I went to the track a few months ago when I had a downpipe,exhaust and Greddy BCC. I didnt have a boost controller so my car was running a little higher than stock boost due to the downpipe. I had the stock size 255's Sumitomos in the rear and here is what I ran on 93 octane pump gas.
60' 2.068
330 5.762
1/8 8.636
mph 86.75
1000 11.112
1/4 13.168
mph 110.38
I am going to the track tomorrow with brand new Sumitomo 275's in the rear. I will also be running race fuel,have the boost now set at 18 psi and will reset the ecu before I run. I dont know how much quicker I will run compared to my above run after doing these few things but I will let you know tomorrow. I have heard that you can knock quite a bit of time off by using race fuel. I forgot to say that I have an automatic 94 Supra....
