Had another great day autocrossing the go kart
This is Mikes last run. About 55 seconds. Yes, he did beat dad.
Today we ran 205 595r federals in front and 225 888 Toyo's in the rear.
I spun out twice and Michael once. More importantly our natural instinct was to lift if the back end kick out. By the end of the day we were both staying in the gas and drifting/ counter steering out of the slide.
The video doesn't give you a real feel for the speed. about 5 seconds after the start mike was at 60 mph before taking the first left.
I love this car.
In the video watch the engine movement. I need to fix this.
I have no sway bar. You can watch the front suspension to see the body roll. I don't know if this need attention. Pleas give me you opinion.
Jeff Kleiner and gang put on great events.

This video tells us all why we are building this car: fun.
Yeah your engine moves a lot. Is the transmission moving that much too?
I noticed your big braided line tie-wrapped on the frame. Wouldn't after a while the line moving a little scratch the blue powder coat?

Hey Frank
I used scratch proof powder coat.
Yes the transmission is moving all over the place. I hit a bump and it smacks the frame. (see powder coat remark above)
Right now I have ZERO pop rivets in the car. It is held together by a couple hundred zip ties.
Zip ties make is very easy to change. Once everything is where I want it. I will go back an change about 1/2 of the zip ties to "P" clips (fastened by screws).
Funny this happened today. I kept hearing this squeaking noise. But Michael could not hear it.
After a couple of runs with this noise, I discovered it was my helmet rubbing on the rubber Kirkey emblem on the seat.

... low polar moment of inertia... it is addictive, only thing I love to autocross (besides the kart)
the fun factor of mid engine is intoxicating. You will learn so much about driving and how to use the car as a tool to "dance" that edge of control, mid engine, lower polar moment of inertia, faster to change directions. This can be good and bad! hmm kinda like the shifter kart!

Watching the video - Do you have broken or non-existent motor mounts? I have never seen an engine pitch around so much. And - the pitching is fore and aft, not side to side. Normally engine torque will pitch the motor side to side. What's up? Do we all need to add additional "pitch stop", or other engine movement limiters to our engine/trans. package in the 818?
Hi Tmoretta
The engine and transmission mounts are not broken (yet). There is no pitch stop.
The mounts are oem and are 10 years old 93k.
You get side to side motion on a front engine with rear wheel drive as it is the reaction force of twisting the drive shaft. This style car has only 1 / 4 the torque going to the axle because of rear dif ratio.
On a transaxle you get forward reverse pitch as the reaction of the half shafts going to the 818 rear wheels. Full axle torque in first gear 13.5 x 225ft/lbs at crank is 3037 ft/lbs of torque twisting the motor assembly. On the 4wd wrx half of the torque goes to the back wheels. So only 1/2 much pitch on the motor.
Options:
-harder durometer engine and trans mounts. (expensive)
-dog bone pitch stop from air conditioner compressor bracket to the fire wall.
-custom trans and/or motor mount and/or pitch stop.
Fixing this is pretty high on my list, so I should have something in the next 3-4 weeks.
Bob
PS: I'm worried about the guys with bigger turbos hitting the shock tower brace.

Spin Wednesday
I don't know if anyone has published a video of an 818 spinning out yet.
In this video Michael has a nice save at the 7 second mark, then another at the 9 second mark.
At the 12 second mark the back end kicked out to fast to save.
For all you auto crossers, think more rear grip.

Which springs are you running front/rear, and are you running a front sway (and what size)?
Hi Tamra,
We are stock 818 Street. 350# front 275# rear. We are not running a sway bar at this point.
-2.5* camber all wheels, 2.5* front caster. 0 toe front and rear.
205/40-16 Federals in front, 225/45-16 Toyo R888 in the rear.
We are getting ZERO push in the front and not getting any heat in the front tires.
The rear is pretty loose and tires only 15*F over ambient(guess) with 1 minutes runs every 5 minutes.
If you have any ideas about this, let me know.

Bob, our thoughts:
The lighter rear springs should help rear grip at the expense of some squat on acceleration.
No front sway would encourage oversteer relative to adding a front bar.
Camber and castor are probably fine but you would only really know by using a pyrometer (probe kind).
Tires, we run matched sets always but at least yours are similar tread wear. More tire is usually better, but if you're not getting any heat in the tires then of course they will slip easier. I'm guessing you'll find that to be different in the summer temperatures.
The general autocross setup is for a car to push if you enter a corner too hot, and oversteer is only induced by power or trail braking. Of course, the degree of each is dependent on personal preference.
We will be running 500lb fronts, 300 rears (we are worried this will be too soft in the rear, but only time will tell) with a front sway, size TBD.
Just our thoughts though, as we are by no means professionals!
Hi Tamra
Thanks for your thoughts.
I would love to go out to a circle pad and try to tune front and rear grip.
I'm worried about oil starvation so I'm going to wait for my accusump first.
I'm not going to change anything until I get wider tires in the back.
We are going to start working on the body with the autocross season over.

Michael And I were over at the barn today looking at the car figuring out what we wanted to accomplish before the last autocross of the season NOV 30th.
We pulled the rear wheels of to look at a brake modification we are planning.
Then we noticed tire rub marks on the lower trailing arms. we are running 1/4" to 3/8" of clearance.
I don't know when it is happening, but both rear tires are definitely rubbing the lower trailing arm. I suspect during heavy acceleration or braking the back wheels are going toe in.
Between rear suspension, shock travel, engine movement, braking performance.
I'm going to need about 6 go pros on this car at the next autocross.

I'm thinking of running a non-pressurized system.
Can anybody give me a good reason to run a pressurized system?

Bob, are you referring to a vent in your water reservoir as opposed to a closed water coolant loop? I can't see any reason why either way wouldn't work, just have to be mindful of contaminants and evaporation with a vented system.
Hi Stiwrd
I would have a closed loop system. I just would have a vented cap on it. I was thinking of a bottle like this on up high in the system.

My F500 has something similar, though it is pressurized. Water comes off the head and into a swirl pot at 90 deg to the vertical axis of the pot and then leaves through the bottom. It allows air to settle at the top of the pot. The only thing you would need to do is make sure wherever you place your pump you don't have enough differential in your inlet and outlet flows to empty the reservoir faster than it refills. In a closed system inlet = outlet (or you start pulling a vacuum and collapsing hoses). In an open one it just pulls air to fill the vacuum if you pull too much.

Today we installed new motor and transmision mount. We used mounts that are 70A durometer rating. (not as hard as a hockey puck) About the hardness of tire tread. The original motor mounts I would compare to the pink rubber pencil erasers we used as kids.
We were able to change the mount without removing the engine from the car. Removed the shock cross bar and hoisted the motor about 2" was enough to change the mounts.
Initial test show we went from +/- 3/4" of engine movement to maybe +/- 1/8"
We still have an option to add a dogbone from the compressor bracket to the rear firewall.
That mod is on hold until on road testing.

That would be a great improvement. Hopefully the road testing shows the same!
I am a beta tester for Mechie3 installing a AWIC kit into my 818.
The first thing I had to do is Clock my turbo.
This is the original position of the turbo. As you can see compressor is horizontal.
After removing the turbo and clocked the compressor about 60 degrees clockwise, this is what it look like.
Craig is sending me a bracket to hold the waste gate actuator in this position.
Next was to mock up the AWIC mounting, using Craig's brackets.
We are going to change the short piece of pipe to a 45 deg bend to improve the fit.
I believe this to be the cleanest AWIC instillation.
I should have this fully installed in a couple of days, after a couple of parts come in.
I will post some final pictures.

Bob is doing a different HE. I have three other people doing the HE installation though. 2 people are testing complete non-clocked systems, another person is testing just the rear AWIC mount installation and the front HE.

Hey Craig
Which holes did you intend your bracket to go to on the transmission? It looks like it will fit in either.
