You ran a 14.9 in a 14.0(stock) car. You should have beat that SI but it is hard to launch a TL-S without getting alot of wheel hop

I won that race, and show me a auto TL-S that gets 14 stock, the guys with the camera were cheering on the SI. That SI has Every bolton and Hondata. He is awaiting the turbocharger in the mail now.

civic is souped up right and yours is only modded because he beat you... fuzzy logic works every time.

@gtdrummerdude went back and calculated the DAs on some other runs, and it seems that it runs slower in -1000 weather than sea level to +800 weather. I'm not sure why. At the same track with -900DA it ran a tenth and 1 mph slower. I noticed the same problem at other strips as well, and it baffles me, this shouldn't be a problem on an EFI car. The 60 foot times were actually a tick slower on the 13.9 runs and it was still quicker. Weird, maybe it really does need a tune.

@gtdrummerdude Yup, mine runs slower at a lower DA for some reason. With one less mod it ran 14.1s@99/100 in 1000-1500 DA. 13.9s were done at basically sea level, -150DA, still feels slow though. Shift kit and a tune are on the way, so we'll see what that changes.

[gtdrummerdude]

@03basesedan I'm in the same boat, but your car probably beats most cars on the road, making it a quick daily driver. I was running basically the exact same times as you out here in Phoenix at the end of November, and I was also on all-seasons, 225/60-15. Your density altitude has been close to -2000 ft this month though whereas mine has been around +1000 which is actually great for Phoenix. If I put the difference into a DA calculator, my car would run 13.4 @ 104.8 mph at Cecil. Sweet.

@gtdrummerdude ran a 13.907@101.38 the other day, 13.9s on all the other runs too, and i still think mine is slow. all-season 215/65/16s.

the si won the race but the TL had a better time.

[gtdrummerdude]

Read my response to karsseboomh22. The new SI's are ok once they have intake, header, exhaust and Hondata but still only mid 14 worthy (in my area anyway). A would say a fast street car is a car that cuts 13s @ over 100 mph on regular all-season tires.

[gtdrummerdude]

But an intake pipe with filter is worthless and the cars already come with high flow exhaust systems. The K20 responds well to TUNES which is why I think it was tuned. Plus I raced a friend with an '08 SI that had intake, race header, full exhaust, and Hondata turning 8900 rpm and I put two cars on him back when my car was runnning 14.7s.

[karsseboomh22]

well the k20 responds to mods very well so its most likly true...

[karsseboomh22]

they do run low 14s, 14.2 according to car and driver
