    Saturday afternoon update:
    I duplicated the cardboard cross section of the transfer case and cut down nearly everything but the input shaft center hole and the output side boundary to see what position it would have to be in to line up with the transmission output shaft and differential input flange as well as not hit the seat and go below the frame. The hole the rod is going through is right at 3.5" below the input shaft centerline which means I'll have to raise the engine, transmission, and differential all up by that amount to get everything to work. I checked the intake manifold height and that means I'll need to modify the hood center hump to raise it about .75" (my estimate). Since I thought about making longer A-arms for the rear anyway so I wouldn't have to run such large spacers, a change in the axle lengths due to raising the differential won't be such a large impact. Well, large impact is relative...


    I'm also taking a look at how the seating position will have to change from normal. It looks like I'll need to move the base of the seat forward, raised by 2", and tilt it back more. I can compensate with thicker padding towards my knees so I'm not trying to stretch out and rest my feet on the pedals. A removable steering wheel will be a 'must have'


    Still more to mock up, but I'm almost back to thinking this is doable

    Will this be a manual shift 4 wheel drive or a full time all wheel drive system? I assume the modern all wheel drive systems are computer controlled? Hope this fits. I'd love to see this plan come together.

    If I can get it all to work, it'll be full time all wheel drive with a 1:1 ratio only in the transfer case (no high/low since that adds weight, complexity, and size). 6 speed manual for the transmission.
    Everything will be mechanical - upgraded viscous in the center and front, Torsen in the rear.

    A bit more cutting took place and the transfer case I'm looking at was put in place. Turns out I need to cut a little more of the tunnel. Good think I have a welder for later haha


    I'm also looking at a different transfer case to see if I can gain a bit more room back for the seat.
    Here's a front to back view:

    Big fan of the "hack and modify" approach. Nice work!!

    Of course we had to do it just to fit in the Gen 2, you're getting 4wd.

    I am sure of two things

    There IS NO warranty. and
    if there was you toasted it!

    I got my coupe about a week before yours arrived. Its sure fun to watch your progress.
    Did you make anything with your bridgeport yet?

    It'll just be hacking for a while haha
    I still have to figure out how to fit myself in too. At 6'2", it's going to be a challenge unless I want the transfer case on my lap!

    Will do! Just don't want to bore people with small, incremental steps since I'm realizing there will be tons of smaller details to figure out.

    I've made a nice 1.5 ton, 9"x40" translating car part shelf LOL
    In all seriousness, I bought a phase converter for it (the mill is 3 phase) that I need to hook up and I still need to tear it down and clean up everything before I put it to use. Parts will probably start once I get the transmission, transfer case, and rear differential all in place and I know what I need to do for support cradles, suspension modifications, brake caliper mounts for the front spindles, etc.

    I love the AWD idea. What is the theory on power to the front wheels? A transaxle is my assumption.

    Yep. Custom tailhousing adapter from a T56/TR6060 to the transfer case, spline adapter if necessary, long driveshaft to the front, and then an offset front differential. At least trying to make that theory work in reality

    See post #39 for the layout:

    I wanted to get some measurements for the rear axle angles and things to see what I'd be dealing with from a 'stock' IRS setup and what I may have to do. I put on a wheel and tire from my WRX's summer setup even though I know the wheels I eventually use will be much wider and about 1" larger in diameter.
    For the record, I've run gunmetal Advan RS wheels a long time before Factory Five put them on the Coupe R (over 5 years). Just sayin'


    Anyway... on to real matters at hand.
    It seems the flanges on the frame or the A-arm spacing is off on my car too. I'm not sure if anyone else has it this bad, but for me it's just a small nuisance since I plan to make new A-arms, but I can see it being an issue otherwise. Hopefully this is something Factory Five is working on since I've seen other comments about it recently. I took out the forward bushing to make things fit for the mockup. You can see how far forward the arm is in the clevis:


    For the axles, I wanted to see the stock angle and the angle they'd be if I ran with the diff raised up to meet the necessary transfer case height.
    Here's a picture with roughly a 4" ride height (very slight axle pitch up):


    And here's a picture with the wheel moved down to simulate the same ride height but the differential moved to match the transfer case flange (axle pitch down noticeably with the provided axles):

    In reality, the upper A-arm was hitting the frame so I couldn't simulate the full angle

    So... since I wanted to be wider in the rear anyway, I compared the Factory Five provided axles (bottom) with the stock 2015 Mustang GT axles (top). It's a 5" difference on each side.

    In transfer case to differential mounting news, I picked up a 30 spline pinion flange made for U-joints from a 03-04 Cobra that I'm going to see if it fits on the Super 8.8 pinion flange and in the 2015+ IRS case. In hindsight, I should have looked for a 2015+ F-150 pinion flange but I still may have to do that.


    Here's how I plan to couple the transfer case output flange to the differential. The silver pinion flange will hopefully replace the stock IRS-to-CV-style-driveshaft pinion flange (black) used on the Mustang GT to let me move the transfer case further aft.

    Man that this looking awesome. So unless I missed my guess you are mounting the rear end directly to the transfer case? That what I would guess since my driveshaft is so short.

    My plan is to have no driveshaft to the rear at all. It'll be a solid mount from engine, to transmission, and to the transfer case. The transfer case to differential will be solid through the pinion flanges because the pinions need preload on them and I can't just go spline to spline. I'll probably put in a high durometer rubber coupler on the pinion flanges because the pinion nuts on the transfer case and differential hit before the flange faces meet.
    Everything will have to be in a perfectly straight line to make sure I don't fatigue the shafts or wear out the bearings and bushings.

    Some progress and setbacks.

    I was able to remove the 2015+ IRS differential pinion flange with the help of the Factory Five provided pinion flange to driveshaft adapter and a ratchet strap to keep it from spinning on my. I followed the instructions pulled from dhuff's Mustang GT repair manual. First I tried to measure the free spin torque of the flange which is under 20 in*lbs and then I removed the nut and flange itself with a puller. Not too difficult, but the procedure Ford uses is to punch the nut and stake it into a recess in the pinion gear. Great for holding it place from spinning, not so great to undo.


    Next, I tried installing the 03-04 Cobra flange on the new Super 8.8 differential and found it's a no-go from stock part to stock part. Can you see the reason?




    Ok, neither could I. After measuring with some calipers, I found the spline diameter is just about .030" smaller on the Cobra flange even though both are 30 spline 8.8" pinion flanges. Dang it!

    I put out a request to Nitro Gear and they won't do a Cobra flange with a 2015+ Mustang GT spline even though they have the tooling to do both. I've also got a request in at a local company to see if they can modify the splines. I really would prefer not to have to modify the splines myself.

    Any ideas of places I can contact to make the correct splines even if I have to turn my own flange on a lathe? Even better, a company that might be willing to modify the existing splines?

    Well, you know what you say about the internet... you can't believe everything you read!

    I realize these last few posts are a sidebar or tangent from the usual build, but what I'm finding is interesting nonetheless. Who knew that so many places list different spline counts for the same differentials? Or that the 2015+ Mustang GT and 2015+ F150 ring and pinions are interchangeable if you don't have any towing package that bumps the axle up to a 9.75" ring and pinion? Or that even truck guys on forums don't know what size differential they actually have because they only think of the number of bolts matters (now some realize that was an easy identifier in the past)?

    Anyway, I stopped by a local spline and gear manufacturing business that turns out splines and hobs some Boeing parts. They confirmed that the spline pattern should be a standard 24/48 involute profile which got me thinking. What kept bugging me was that with a given diametrical pitch and pressure angle, you can't just increase the diameter without increasing the spline count. Well, that made me recount the splines on the Mustang GT stock pinion and flange. I thought I mis-counted because I read 30 spline everywhere, but there are 31 splines now!
    Long story short, I ordered a 2015+ F150, 31 spline flange that seems to fit both the Super 8.8" and 9.75" differentials. Once that arrives, I can confirm.

    More silly transfer case and differential info below. You've been warned.

    Good news! The 2015+ F150 flange for the 8.8 and 9.75" diff has the same spline count, same spline diameter and outer diameter (to match the oil seal), and same depth that's inserted. I was able to put the new flange on but didn't tighten it down all the way to get the correct preload. I'm going to pull it back off and check to see if the pinion nut sits at the same height because the white dust shield didn't fully seat when the nut torque started getting high. Worse case I add a washer under the nut to get everything to fully seat.

    Even though the new flange pushes back the mating surface by almost 2", the pinion threads and nut stick out to eat up about an inch of that difference. Note to anyone who needs a longer driveshaft due to transmission choices or driveline angle issues and is ok ditching the Factory Five provided flange adapter, this could buy something like 2.5".



    I cut the bottom X bracing in the Coupe's frame to drop the transfer case forward output flange right to the bottom of the frame line to get it as far down as possible without hanging down to get hit. With the new flange on the rear differential, I put the seat back in to get an idea of the new position. While not optimal yet, it is noticeably better than before. You can also see how high all of the driveline will sit relative to my seat. This will get reinforced frame members around it for sure so I don't break my hip if anything ever went wrong.



    The final two pictures show the height difference again but also show that the seat belt bracket for the driver's right side lower tab will need moved or the other flange on the transfer case cut off. My guess is both.





    Anyone want to sponsor the car so I can fund the transmission purchase in the near future and keep forging on, or get some wide wheels in a square setup, or rear Wilwood brake kit, or other necessary build parts? Pretty please?

    Pretty pictures and charts time (because I don't get enough of that at work haha)

    On a topic that can have infinite discussion with no resolution (also an aspect of work at times), I've decided to try to pin down what I want to do with the transmission gear ratios and final drive ratios. I chose a front differential to match the 3.73 of the Mustang GT performance pack to minimize upfront costs and I would like a fairly good spread of ratios, a 1st gear I can crawl in traffic with (Seattle to Everett), and a top gear I can cruise if the highways are open or take a run further away should I actually start traveling again.

    I cropped all the captures the same so anyone should be able to save the charts to your computer and tab back and forth to see the changes more easily.

    Baseline: 2016 Mustang GT, stock wheels and tires, performance pack


    Second: Gen 3 Coupe, T-56/TR-6060, 3.73 rear, with 2.97 1st, .63 6th, square 295/35/18

    Not too bad at all. I'm also trying to keep in mind that I want my engine to rev to 8000+

    Third: Comparison to my WRX with a 07 STI 6-speed, stock tire size for chart

    You can see 4th to 5th is a small change, 60mph already spins the engine at 2200rpm, and at 75mph I sit at 2750rpm.

    Search for all available differential gears that match both the Super 8.8 and the 7.562" front differential I'm starting with to keep the size down...4.56:1's are available!
    Fourth: Gen 3 Coupe, T-56/TR-6060 with 4.56 rear, 2.97 1st, .63 6th, square 295/35/18

    Surprisingly, this is nearly identical to the crank to mph gearing of the STI I'm used to. Crazy, huh?

    Finally, fifth: A fun thought should I change out 5th and 6th to .74 and .50 with the 4.56 differentials, square 295/35/18

    I can crawl in stop and go traffic, shift similarly to my 390+hp WRX, and still cruise at 60mph like a stock Mustang GT at 1800rpm. Seems like that's full of hypothetical win!

    You really have some good chunks of time to think this stuff through. Looks like you got quite a few things figured out! Keep at it and by spring you'll be go carting for sure. Especially if you find that sponsor! My next hurtle is making my own driveshaft. I need to research and find a place to weld it up.

    FYI if you ever get into making custom splines. WIRE EDM is the process you are looking for. You design the DXF and specify the tolerances and materials. You can supply the blank from your lathe and find a shop that will wire cut the spline in there. I have programmed and run several for years.

    I'm an engineer, I'm paid to over-analyze any design
    I did the FSAE car suspension design in college, was hired to work on the CH-47 power transmissions (though was assigned to a special project on my first day), and now I'm working wing mechanisms, so I'm in the same fun field at work and home hobby.

    A sponsor would be awesome, I just have to figure out how to find one and then convince them the ideas in my head are worth their money or products. Sooo... until I have a great finished car, I'm guessing I'll be completely self funded haha!

    Have you checked out driveshaftshop.com? I expect to contact them about my transfer case to front differential driveshaft since it'll be longer than the average car and custom.

    ------
    In other news, I half convinced myself I need the 4.56 gears. I know the Coupe is going to be lighter than my WRX, but I created a graph of it's current wheel torque vs speed and compared it to the natural aspirated build I'm doing. I can see why the WRX/STI/Evo all feel so fast from the get-go since they're usually not traction limited and the gearing is so low. With my current turbo and tune, it's got a pretty noticeable peak starting from a 5mph roll, but once it gets going, boy does it move quick. The 3.73 gearing of the Coupe, since I also hope not to be traction limited, would be great after 40 but seem slower on the butt-dyno until then just due to the gearing.

    Here's the chart, based on wheel torques of my WRX vs. the wheel torque of a stock Mustang GT which I should exceed easily with my tuning, the better heads, non-restrictive exhaust, etc.


    While waiting on building funds for the transmission, I'll start working on the updated rear suspension design. I'll post as I get that started to be sorted out.

    I realize it's been a long time without an update, but I've also been trying to clear out things in the garage and wrap up other projects at the same time.

    I did a spur of the moment search on Craigslist for the tire size I wanted and a set popped up from someone with a drift car who couldn't fit the tires in the wheel wells. Worked out for me, because I got all four 295/40/18 Nitto NT555 G2's for less than the cost of two.
    I also made use of eBay's recent pre-spring 20% off code for a purchase from a US company to get some wheels. Turns out one vendor was also having a sale at the same time and the cost of the wheels dropped dramatically with the stacked discounts. Add in that they upgraded to a nicer set when their inventory list had an error and I ended up a happy camper! 18x10.5 ET22, square setup in anticipation of the AWD working out.



    As a result, this also means that I expect to sell the 18" Halibrand style set I got when I placed my order for the Coupe. With AWD, trying to match front and rear tire diameters with different widths and not being able to rotate them means it's unlikely I'll ever use them. If anyone is interested, let me know or I'll be posting it up in the classified section at some point.

    Figured I was past due for an update. I'm working on a mix of the theoretical and the practical by focusing on the rear suspension changes required to lift the rear differential up to a height that matches the transfer case output flange and have everything above the bottom of the frame.

    First up was 'compensating' for the height increase by trying out the Mustang GT axles (which I showed earlier being 5" longer each side). I figured if I'm to re-do some of the suspension that I might as well lower the CV angles and one easy way to do that is widen the rear track. Who said we'd need spacers to get rid of the wheel gap?



    This also means I'll get to try out some fiberglass molding again. Weee!
    Here's a side view that also includes the front differential I had to open up to verify the internals. For anyone who cares, the Ford Explorer and Ranger in the early 2000's used Dana 35 internals with a Ford requested case. Many places report the smaller Dana 30 only. Anyway, the body will need to be a bit wider when all is done.


    Finally, I've been contemplating ideas on how to grab all the dimensions I want from the rear spindles as well as possible ones I want to use in the front. After chatting with some coworkers, one strong front runner (that didn't include using a laser scanner or FaroArm which require permission and a business case at work) was to use a center finder combined with a DRO on my mill. Since I don't have a DRO and I wanted to get started right away, a much lower tech solution filled in to get rough dimensions.
    Check out my overturned book shelf and a combination square ruler!


    I'll pull some dimensions from the existing frame and A-arms to get the nominal caster / camber / effective spring and wheel rates as a baseline and then design new geometry with those in mind. I'm still debating the 'easy' direct coil-over setup or a pushrod and bellcrank design. Hopefully more on that on or before next weekend.

    I made some really good progress doing a few coordinate transformations to get the spindles in the correct locations and match up with the 'baseline' Coupe rear suspension. Everything is at least really close without disassembling all the components to verify individually.

    The top is the as-designed-by-Factory-Five layout.
    The middle is the wider version using the Mustang GT axles, raising the diff to match the rest of the custom drivetrain, and using the same chassis mounting locations for the a-arms by effectively extending their span. I also assumed using the upper spring mounting location for a bellcrank to make things easier. Easier always being relative...
    Bottom is the overlay of the two.


    Initial findings:
    1/2. I have an error on the spindle face location for my setup, it needs pulled inboard some (too wide of track)
    1. The axle angle shouldn't be an issue
    2. The angles between the a-arms and the axles is going to cause the axle CV's to probably bottom out because as the car compresses in height (bumps, any aero, cornering, etc), the arms and axles are not close to parallel.
    3. The upper spring mounting locations may actually work well for a good rising-rate spring setup and if I get fully adjustable dampers they can up and easy to access without crawling under the car
    4. I haven't looked at wheel rates, stock suspension travel estimates, or anything else yet.

    Fun times ahead!

    What good is access to a farro arm and laser scanner if you cant use them on saturday for fun? when technology disappears simple solutions are visible! great work! that will be some flare youll be making.

    Big milestone started/accomplished today: I placed the order for the transmission which is the last major component necessary!

    I don't remember if I mentioned it earlier, but this will be a Corvette based T56 case with upgraded TR6060 internals, blueprinted assembly, and an adapter to bolt to the transfer case. It has to be a forward shift location instead of a mid-shift or tail shift. George Kreppein from Rockland Standard Gear will be building the unit for me and also works on the Tranzilla version of the T56.



    Once everything is built, shipped, and delivered, I'll be able to get to work on finalizing the powertrain and make some real progress!!

    While the transmission is still a work in progress and RS Gear is waiting for Tremec to send them some additional gearsets to give the ratios I requested, I went looking to see what I might do for the interior and alternatives to the Kirkey seats that might still allow the even more restrictive space of the wider tunnel and fit my tall and skinny frame.

    I lucked out an found a discounted, yet brand new and genuine Bride Gias II seat. I point out genuine because there are replicas all over the place with varying quality standards in the fabrics and stitching and unknown internals. From my reading, some are fine to sit in, some wear out quickly, some look poor on arrival, and none are crash tested. You can get a pair of replicas for half the cost of a single genuine seat. It may be the 'sport' model aka least expensive model of that line, but the only difference is the internal frame is heavier and the back is a metallic painted fiberglass instead of the usual but more expensive Kevlar. It's based on a FIA certified model but has a recline ability. The 'Low Max' setup puts the top of the cushion only about 1.5" off of the very bottom of the seat.

    Here it is in the car testing out the recline:


    Here is the side by side comparison to the Factory Five option of the Kirkey high-back seats:

    I'm jealous. That is a nice seat and I really like the style/aesthetics of it. I went and looked at seats too but I am already over budget and had to put that off for another day.

    I've hit my budget cap too so the only reason I felt comfortable buying it when I did is that I should be able to sell it for at least the same price rather quickly. That's also the reason I only bought one!

    You sure have a bunch of things to be researching and figuring out.
    keep up the great work!

    keep the updates coming.

    Just a few more things to figure out hahaha
    Really it's down to the engine build, the drivetrain assembly, new suspension design, bodywork modifications, and the usual kit building steps.... crap, that is a ton

    Here I am hitting refresh on the transmission tracking number (just departed Salt Lake City) and you have a sweet looking paint job and much of the car assembled already!

    Small update but more of making progress on a project to make progress on this project.
    As you can see, the engine is clearly [physically] closer to getting installed


    I had to move the engine to make access for the Bridgeport mill teardown. I'm making good headway on the head disassembly so next is the turret and the table before I can pull the knee and strip the existing paint before starting to refinish and re-assemble:


    Thankfully the head was rebuilt shortly before I bought it but since it was still in use at a machine house before sitting outside under shelter, it does need some cleaning and re-greasing and oiling. The motor, varispeed drive, quill, and spindle all look in really good condition so thankfully my cheap mill can remain low cost to me.


    Last but not least, the mill will be first put to use making an adapter plate to the adapter. With the transmission output shaft being uncut as requested, there's about a 1.5" gap. I also don't know if I'll stick with the recommended Borg Warner 4404 or switch to the 4412 which has a much different mounting pattern. A takeout unit with a 31 spline input shaft will be crossing the US to let me check it all out.


    I'm looking forward to a little less planning and more cutting chips, test fitting, and welding in the future.

    Not too much has changed (as seems to be the typical), but the Bridgeport disassembly continues. I now have the turret off so all that's left now is the bed and knee before I can start stripping paint.

    On the drivetrain side, I received my Borg Warner 4412 transfer case. It seems to be one of the few 31 spline inputs that is full time AWD with no hi and low gearing. The other is the BW 4404 seen in the previous post.


    Unlike the 4404, the 4412 is shorter after the chain, but longer in front of the chain. Instead of having to add another spacer like I thought I'd need, I'll need to shorten the existing adapter by 0.6" instead. The mounting holes are also a larger PCD which makes the mounting flange on the adapter too small too. Work, but not terrible.
    I've kept the critical dimensions of all three transfer cases I've tried (4404, 4411, and 4412) which shows I'll have the most seat room with 4411 but only .5" more than the 4412 which has the correct input splines. Meaning no custom billet input shaft required. Yay!


    I hope to pick up a Harbor Freight scissor transmission jack next weekend to lift the entire engine block, bellhousing, transmission, adapter, and transfer case into the car to figure out the new motor mount location as well as the final drivetrain height. Once the Bridgeport is back together, I'll use that and my lathe to modify the adapter.

    Still seems like not much has been happening on my end, but I've been busy with a new role at work which lets me be in more of a shop environment so I'm still getting my hands on work fix during the day/week. Still an engineer, but now I also get to help other engineers test ideas and improvements they have in a more rapid environment.

    As a result, the car only now has the block, bellhousing, etc bolted together to get a more solid idea of the length and rotation of the transfer case to front diff driveshaft. I've got an idea of how I'll keep everything in alignment while modifying the adapter but I'm running that by some people in the shop to see if there's something better they can think of. Once that's done I'll make a quick coupling from the rear output of the transfer case to the rear diff and have one giant bolted assembly. Something tells me this won't drop in easily!


    I've also been spending a lot more time while in the garage working on the Bridgeport. I've got it completely disassembled (meaning parts galore taking up floor space) and mostly stripped of paint, filler, and oil. Here's a 3 frame progression of the state of it. Original rusty and oily state, then needle scaled, and now Zep Purple cleaning and degreasing in the works.


    Up next is primer and paint for the mill so I can re-assemble and start making the new engine, trans, etc. mounts
    For the car the next step is modifying the adapter. Hopefully with a bit more speed this month!
