Maximizing traction by increasing rpm and tire size

For reference, I'm currently at 515whp on 255/40/17 on 120utqg semi slicks and battle traction issues constantly. I'm on boost by gear 9psi in 1st, 13psi in 2nd and ~20psi in 3rd-6th. If the conditions are just right, I'll hook 3rd gear with full boost but most of the time I still have to feather it. By the way, these are all reference to running the car on the street. The track is a completely different animal as the tracks are normally prepped and sticky as hell. Last time I ran at the track I hooked 1st-3rd very hard, no traction loss.
I agree with Junky, if you want more traction under the circumstances you've given, go with good sticky tires and as wide as you can go. The taller tire will probably help but keeping as little camber as possible and laying as much rubber to the floor is whats going to give you more traction. But loss of traction might be a good thing at this point, that's at least the way I see it, I'm probably saving my stock diff and trans from breaking by sacrificing some grip lol.

You will need the following: puddymod/8.8/R200 diff with a taller FD and a set of drag radials and at 600whp with the stock trans plan on using boost by speed/gear in the first two gears and ramp it up in 3rd. If that all seems to work your clutch will be the next to spin if you aren't running a twin disk. More boost more problems.

I’m turbo’d with 617/442 dyniojet. My s2k sees mostly canyon/mountain roads. I find that boost by throttle works for me the best after playing around with boost control. This is on stock AP2v1 wheels and RE71-R tires.

Soulicious you are an inspiration! I'm running AEM Infinity so i can do boost by gear/traction on my 2004 AP2. I don't plan on doing hard launches from a stop, but more like highway pulls/rolling anti-lag launches

OP you do not want or need to run DR's. You will compromise the handing of your S2000. Not worth it when you can get very good traction for strait line with an appropriate size R comp for rim width, like a Nitto NT01 or Toyo RA1 or R888R while retaining good handling/corning control.

Found your post about boost by speed. Brilliant! So simple so elegant lol. If it existed i would do the following: 255/45/17 Michellin pilot sport 4S with 1"wider ap2 V1 wheels. this would be one Killer set up with boost by gear/speed!

As my screen name implies i want to have a Formula 1 S2000 lol. It's gotta pick up and go and dart through turns like a F1 car or bust! High redline, high HP, Quick Acceleration and turns. S2K can do it
