Race Tracking Your Supra - Information exchange

[Eyelise]

The very outside of the shoulder on my front left PSS took a beating at the last track day. The rest of the tire looks actually fine, just the very outside. I run 36lbs hot and may have to bump that up a bit. I am also adding camber plates and considering moving to soft on the Eibach front bar. I was told by someone at the track I could remount the fronts swapping sides. Has anyone done this? I’d like to make it a few more track days while I order new wheels and tires.

you should stay around 35-36 hot and solve outside wear issue w camber

Went to a new to me track this weekend. Thompson Raceway in North Eastern Connecticut.

Fun track but I finally experienced fuel starvation about six times. A good amount of sweeping right turns at this track. Ironically the section where other supras have experienced it, I only got some "light" starvation where the car would just kinda stop accelerating like I let off the throttle, and then in this right turn that is nowhere close to g-forces I was experiencing in the other section, I got MASSIVE fuel starvation on WOT coming out of the turn. Huge backfire and it felt like I hit the rev limiter. This was only with two bars gone on the gauge too, so about 3/4 tank or more.

I might have to limit my trips to Thompson, or get a fuel starvation solution, which I really do not want to do.

And how low where you? I always go out with a full tank.

Whoa.… you got this even when going out with a full tank?

Hahha yea totally. Ironically I have yet to experience this at Lime Rock and that is the track I am currently fastest at, being my home track.

It's interesting too because turn 1/2 at Lime Rock is much like this turn at Thompson. Maybe the banking and surface changes at Thompson compounded it.

What PB atm at Lime?

First session I went out with a half tank. Probably impossible to go through that much gas in a single session

I've had a couple sessions where I was on track lapping for ~30 minutes and I'm always shocked at how much fuel I burn.

Last time I went out with just less than half a tank for a 25 minute session I had to come in early because I was getting "light" fuel cut and my car was screaming at me about being at fuel reserve with 2 bars remaining.

makes sense. I was basing that on my “marathon” session of 8 laps (2 of which were cool downs) ?

seemed like I went through no fuel.

was my first session there

@kyle9 do you have onboard from your 56 lap? curious where you're picking up time vs my setup
i'm the guy who looked up the zf8 neutral info for you on sat

Nice times! I'm still slow AF on Lime Rock lol.

If you don't mind me asking, what mods are you running?

Hey! Peter, right? My SD card was full and my gopro stopped recording. I do have Garmin footage I can send you though

There was probably another 1.5 seconds in it but the track was terrible next couple sessions and I kept messing with my setup (and only 2-3 laps per session)… and obviously I didn’t get to run the next day when the conditions were much better ?

yup that's me, garmin footage would be great, thank you. will be back there this sat to try and get into the 56's, only .06 away

Yea it helps that LRP is pretty short. I usually don't stay out all session at LRP anymore as it just annihilates the front left tire.

Last event at LRP I got lucky with a good string of open laps and was blasting 58's basically the whole session, all a second or more off my PB but it was nice to see I can be sort of consistent if I try. Zero fuel starve.

At Thompson I would fuel starve after about 4-5 laps and that was the first time ever for me at that track so I was not pushing as hard as I do at Lime Rock. It would probably starve earlier once I get to know the track better. Every track I go to I *always* go out with a full tank every session.

typical track driving would be around 5~7 mpg depends on session as well as car setup. so you can bak calculate how much gas used in a session if you know your mpg on track.

Who? The tag didn't load I think

I think @razorlab is referring to me.

Sorry late to this party, I'm on RS Pro3 divorced rear so I may not be much help. I do know someone with RS Pro 2 but I think the rear is also divorced, could get you his settings for the fronts at least.

When I set mine up I used the factory JRZ baseline then changed the fronts to load up a little faster/unload slower. Then I set the rears to load slower/unload faster. I did this based on some feedback another forum member got from 057 motorsports.

I'm no race engineer but I know what I feel, the car seems to be more prone to entry oversteer which I like.
