    Test and tune today

    Michael and I spent the day at an autocross test and tune today.
    I would estimate about 50 runs today.
    We beat hard on the 818 today and she withstood the challenge.

    A couple comment on systems.
    Filled our self bleeding cooling system. Started engine until thermostats opened. Added a pint then shut the cap.
    It suck in another 8 oz from the overflow bottle after cooling over night. Refilled this morning, Held that level all day. (7 hours of intermittent runs)
    Dash temp meter was right at the mid rang point all day long. My radiator fans were under ECU control.

    AWIC system was holding initial level. Drive car off trailer caused fill tank to drop 1". Refilled and it held that level al day.

    After 4 or 5 hard run in a row we could not leave our finger on the hot side of the intercooler. I estimate 150f.
    The cooled side was lukewarm. I'd estimate 100f. Ambient was 85f.

    Our square brake system we though was working great. On Mike's last run of the day. He was coming into a very tight turn very hot. 50 mph, very hard braking and hard left turn resulted in rear lock up with an instant 270 degree spin.

    What is the best way to clean virgin fiberglass of cone marks?

    Since I was running with no engine covers or aluminum panels in the engine bay, I really can't come to any conclusions on my engine bay cooling solution.

    The gopro wasn't ready for today. Just a couple of pictures.

    Is the self bleeding system the barb fitting added to the coolant pipe? I can't remember where you had your overflow bottle, front or rear.

    Wookie test

    Today at autocross, 4 big guys(>6' >250 lbs) tested my WOOKIE seat configuration in my 818.
    They all love it and said it was very comfortable.
    One 16 year old. 5'8" 130lbs tried it. He couldn't see over the steering wheel.

    Hi Craig,
    Don't use Wayne's mode with my system.
    My whole engine cooling system is in the rear.

    tanks.jpg

    Tank on left is for the AWIC filler tank.
    Tank on right is engine overflow bottle.

    Today was first real test of your AWIC system. All works great.

    By the way, I went with a BMW AWIC pump for my AWIC.

    Bob, are you considering adding pre and post intercooler temp sensors? From our autocrosses, our post intercooler temp was hitting 100 during full boost, but dropping back to the 70's immediately post run. If yours is sitting at 100 post run, it might be getting pretty hot mid run. Are you data logging at all to watch for any knock correction? Also, we were spraying the intercooler heavily with water, we had ducting, and we were leaving the car idling to keep the fans running and the AWIC cycling.

    We are getting the rest of our speed density tune on Tuesday (sensors installed now), and the tuner will pull timing in relation to the post IC temps in case things heat up too much.

    Hi Tamra,
    I know how important data logging is. Not installed yet.
    We beat the 818 this weekend. Over 60 runs really pushing as hard as we could.
    The metal neck going into the throttle body was showing no heat by my calibrated finger test.
    I do not have any fans on my awic heat exchanger.
    We were typically shutting of the car during our quick driver exchanges.

    With all the talk of "Turning Radius" Here is a quick video that shows the radius.
    The 818 was slow starting because the motor got rotated backwards during the spin. Didn't get the clutch in fast enough.

    At this past weekends autocross we rented a uhaul trailer. Here is a picture of the ramps needed.

    We also loaded it backwards as the front bumper would hit the tire stop on the trailer.

    This picture is also a good view of the tire width.
    The front are 205's and the rears are 225's
    Both at -2.5* camber

    That's approaching comical. But yeah, the uhaul trailers were not designed with race cars in mind...

    Mounted hood and cut side scoops

    A couple of small thing got done this weekend between college graduation and daughter moving.

    Got the hood mounted and side vents cut. Still need to trim the returns on the hood.

    Thanks Tamra,
    Still need to trim the lip edges on the hood. I will also add some bump stops to raise the front corners of the hood to match the bumper.
    Your body panels are fitting up nicely.
    I have my side sails back about 1/2" to avoid cutting at roll bar.
    I don't know how this will affect my doors.
    I also will have to do something to make the sail-fender interface look better.

    Heading out to the Wilmington airport pad this weekend.
    Saturday test and tune, probably 60-80 runs between Michael and I.
    Sunday point event, 12 to 16 runs between us.
    Another weekend of beating the *** out of this car to see if we can break anything.

    About 30 autocross runs

    Today we had a beautiful day for about 30 autocross runs.
    We let a couple of very good drivers take the 818 for a spin (literally).
    They recommend some bigger back tires and some better alignment.
    Both I knew we needed.

    The car was only backwards on the coarse a dozen times.

    Here is one of Michaels clean runs.
    Turn up the volume and you can hear the tires working.

    Do we need a front sway bar?

    Couple of pictures from yesterdays autocross.





    Stock 818s springs. Right now we are not running a front sway bar. Maybe we need one.

    Hi Bob good to see the body on and running on the track. How did the cooling systerm work with the body on? Are the radiator fans still controlled by the ECU and can you record the data with romraider on a auto cross run? I am interested to know if the fans are running as you are cranking it up in the course. This would show if there is a draft through the radiators at speed.
    Keep up the great work!!

    Hi Don,
    Our rear mounted radiator fans are controlled by the ECU (2 speeds)
    They do kick on sometimes in low speed but never seem to come on for more than a minute.
    I have not done any data logging yet. Shame on me.
    My testing is still suspect as I don't have belly pan or wheel wells installed yet in the engine compartment.
    I was planning on having the complete engine cover on this weekend but my radiator supports are interfering with the rear hatch hinges.
    I also have no windshield and no block off sheet metal in my humps. All these things will effect cooling.

    Bob

    We have the R package suspension. We put the 500lb springs on the front and it feels good - we may not need a sway bar. We have not tested the car as much as you though. Our car is also not oversteering (other than on throttle), and actually has a slight understeer bias at the limit, off throttle. We also had 245 Hoosiers on though...

    With the 300lb springs in the rear, we are hitting our bump stops some, so I imagine that you are too. We will likely need to go to a stiffer spring in the rear (which might mean we'll need stiffer springs in the front too to keep the current handling). If you are hitting your bump stops mid corner, it could definitely break the tires loose and cause a spin. Basically, you'll go from your current spring rate (275# rear), to infinite spring rate, which would cause snap oversteer mid sweeper.

    I think, with the 818, that increasing the spring rate until you're not hitting the bump stops would be the first step, followed by either a sway bar for further fine tuning or playing with shocks/springs options more. The good/bad about running e-mod, is that your options for suspension changes are wide open. Then, you get to add aero for further confusion

    With the 300lb springs in the rear, we are hitting our bump stops some, so I imagine that you are too. We will likely need to go to a stiffer spring in the rear (which might mean we'll need stiffer springs in the front too to keep the current handling). If you are hitting your bump stops mid corner, it could definitely break the tires loose and cause a spin. Basically, you'll go from your current spring rate (275# rear), to infinite spring rate, which would cause snap oversteer mid sweeper.

    I think, with the 818, that increasing the spring rate until you're not hitting the bump stops would be the first step, followed by either a sway bar for further fine tuning or playing with shocks/springs options more. The good/bad about running e-mod, is that your options for suspension changes are wide open. Then, you get to add aero for further confusion

    Hi Tamra,
    Thanks for your insights.
    All of our testing so far has mostly to prove reliability. Which has been good.
    We have had to tow or nurse our Impreza home from an autocross/rallycross a couple of times.

    We have not looked an suspension yet, mostly because we are not sure what were doing.
    On our gstreet Impreza we were able to go from understeer to neutral with a bigger rear sway bar and higher rear tire pressures.

    We are running four old 205 federals right now. I suspect we are only at 0.75G when the back end breaks loose.
    We are in a learning how to drive a loose car with power. Michael with 40 year younger reflexes is killing me.

    One note. The course Sunday was pretty fast. There were about 4 places we were hitting rev limiter in second gear.

    Keep any setup tips coming,
    Bob

    If you use that as your basic set up training, then you're on the right path. Big rear sway + higher pressures would make the rear looser (or reduce understeer). Basically, you need to do the opposite with the 818, since it is already tail happy (front sway bar, and either higher front pressures or lower rear pressures).

    Then to add on top of that, since you are not in a stock class, you can play with spring rates (with your G-street Impreza you had to run stock springs, so it forced you to go to a sway bar). Without overcomplicating things, you can use springs the same way you would use a sway bar (very high level of course, as suspension set up can be super complicated) - stiffer rear springs will have a similar effect to adding a rear bar to your impreza (will cause more oversteer), or adding stiffer front springs will cause less oversteer/more understeer. You have to find a balance of course. Too soft of springs means you hit the bump stops as I said before, which can cause sudden and drastic loss of grip. That could potentially be your main issue right now.

    Of course you can WAY overcomplicate things when you start "fine tuning".... but for a basic start, that's how it will work. People who are really into suspension setup will bring up at least 20 other factors you should consider, I'm sure. IMO, start with the basics.

    TINY tires! Well, they will let you figure out the balance of the car well, because they won't mask any mistakes!!! If/when you go to hoosiers, they will hold a lot more G's and will compress your suspension more (basically, if you aren't hitting the bump stops now, you will be!). Also, if you are running a square setup, the car's balance will change quite a bit if you go staggered.

    We will be in Toledo, OH for the SCCA Pro Solo at the end of June (with the S2k, not the 818). Are you guys attending? We'll also be in Wilmington at the beginning of August for another Pro. It would be fun to meet you!

    I don't know if we will be in Toledo, but I suspect Craig will be there.
    This past weekend for us was the Wilmington Pad you will be on in August.

    I just asked Andrew his opinion, and the only thing he'd add is that when you have open suspension, you shouldn't ever tune the car's balance by tire pressure. Set pressures to make the tires happy, camber for the same.

    Bigger tires for the MRG 818

    After this past weekend of autocross spins, It's time to look for some bigger shoes.
    We were running some 205/45-16 on 16x6.6 48et rims
    A friend let us barrow a set of 255/40-17 on 17x9 35et rims.
    Here is the difference in size.


    rear view



    The side view show it very centered in the wheel well at4.5" street ride height.



    Michael (Bigger is always better) says lets try them on the front.



    They actually did fit except for just touching the firewall at full lock. I suspect the will hit the fender a full turn and full compression.

    I took a lot of pictures and notes. If anybody has a questions, let me know.
    Bob

    I won't be there this year. I did win R1 in Toledo in 2013 in a borrowed F500 though after machining tons of custom parts for it. lol. I'm still sticking to only local events still until the baby is older.

    I've heard that the federals aren't the stickiest of tires, which certainly isn't helping. Those 255's look like Star Specs. On my F500 the handling is very very different on year old tires vs fresh stickers or even just current season's tires.

    We used the federals last summer with success. Did not store them in the warm over the winter.
    Now that we have all the engine system sorted out, it's time to look at the suspension.

    Those tires are Hankook ventus R-s3 off of a friends FRS.

    Black, I wonder what it would be like to ride an electric bike. Maybe someday if my liter doesn't kill me first.

    Here are a couple of high resolution straight on tire shoots with measurements someone might want to use for reference.

    Good looking bikes. I think a buddy of mine Shane Turin has raced one of your bikes at Laguna a few years ago.

    Hi Mitch,
    We had 7-8 riders race for us. I don't remember a Shane. There was Shane Turpin that rode a competitors bike.

    Andrew used to work at Brammo. Electric motorcycles are so cool! I enjoyed riding with him on the Empulse. The sound of revving the electric motor is something I'll never forget, and the looks we would get from Harley riders were priceless!

    Shane Turpin worked for the Yamaha Champions Riding School while I was at Miller Motorsports Park. He has said how impressed is has beenwith the performance of the electric bikes he has ridden
