Well, the air was cool and the track was sticky, this is what my best run looked like of the night:

R/T: .438
60': 1.89
330: 5.549
1/8 et: 8.601
MPH: 81.62
1000: 11.23
1/4: 13.482
MPH: 101.75

My mods are Invidia Catless Downpipe, Invidia exhaust, K&N Drop in with Intake Silencer Delete. Everything else is stock and ran at full weight.

Yeah.. took some air out of the tires and just kept revving up trying to build boost off the liune. She hooked nicely and I couldn't be happier. I wish the run before this one I wouldn't have missed 4th gear. I cut a 1.7 60' on that run and was one tenth faster through the 1/8 mile than this run I posted. Wound up coasting in nuetral after the 1000 foot mark to a 14.0@ 83Mph....LOL.

Only dropped tire psi to about 30psi down from 35. I have seen stock WRX's(06-07) run a 14.0 at like 95mph stock. I guess the stock times for STI's are similar to what I ran.

I have never felt a difference in launching with different tire pressures. I reduced my fronts from 35 to 30psi. But then again, i'm a FWD non-Subaru. So it's different. I have seen people at the strip adjusting their tire pressures for every run and I just don't see the point. Just show up, line up and run....

Drag rubber on a relatively stock WRX would be silly. AWD has so much grip that you can't get much tire spin anyway. Drag rubber starts to be useful when you start to exceed ~100whp per powered wheel. That's nothing for even a stock RWD 4.6L Mustang GT but it's a ton for an AWD 2.5L subaru. Once you get to 200+whp per wheel or more, drag radials become almost a necessity to get even half way decent times for your power levels. How many 800+whp WRX's do you see though?

There are the stroker kits and other methods to get there. I have read about several in the 790-810AWHP. One was complety stripped and everything though. Other guy said he cant use the power cause when it hits, its a rocket, and really slow before the turbo start spooling.

idk, my tires at reg psi it spun a little too much for my liking. Lowered them and cut better 60's. best 60 I could get at full tire psi was a 2.0. Best on lower pressure was a 1.7.... but missed 4th on that run.
