Default Stock gsr 12.570@120 on street tires..12psi

Setup is

AFI street kit 57trim Tunned on 12psi E85

car is daily driven atleast 50 miles getting about 22-24mpg and i dont baby the car....158xxx miles on the stock motor

The car weighs 2750lbs with me in it...

my best time prior to this was a 12.604@118.34 best trap before was 119.20

Tires are Nitto neo gens 205/50/15

60ft: 2.162
1/8: 8.420
mph: 93.91
1/4: 12.570
mph: 120.12

i hit the 8400 rev limiter right as i crossed the line...guess ive about maxxed out how fast i can go on street tires...

given the weight of my car and the trap speed im guessing it was making 350-360whp????

i need to get some slicks on it asap!

Yessir!

Given your 60 ft's, I'd say you got a 12.0* or 11.9* waiting 'round the corner with some slicks! Are you gonna go 24.5's?

with that power id think you can go a little quicker.

I did a 12.1@118 on an ebay kit in a full weight integra on 10psi on street tires spinning first three gears. I did cut a 1.9 60ft though. i think with a good launch a lower 12 would be possible on street tires. using the TCI calculator i was making approx. 300whp

doesnt that time say 12.18@116mph?

yeah that 60ft is where it was... also your 1/8 mile was really good...im dead positive you wernt spinning first 3 gears if you were able to run a 7.9 1/8 mile...im sure the car could do alot better if it didnt spin so much in 2nd...i have to feather it alot... for a track that only has VHT the first 60ft i think it does well...ive yet to run the car on a good track like Woodburn or SIR...

When i dynoed 321whp i was trapping 115-116mph so if you were trapping 118 id put you close to the 330-340 whp...

but im pretty impressed on your times though... it was a teal gsr right?? 94-95? wasent it an LS/VTEC on 10psi?

It was originaly an LS automatic. but yes, the 12.1 was a basic LS/VTEC at 10psi. My car full weight with abs and all with me in it was right about 2550 with a half tank.

I was using this calculator. which would have put me at 327hp
http://www.tciauto.com/Product...asp#0

For reference i have this one which is the B20 on 13psi


The car would hook for 1st since they were using vht in the 60ft, but then id hit second and start blowing the tires off, and it would spin at the topo of third. If i had put some 22" slicks on it would have done a high 11.



I wanna see pics : )

Ahhhhh that explains it.... i was wondering how you got the 122 trap with 15's on there.....like i said i hit the 8400rpm rev limiter as i crossed the line... the ls tranny maxes out in 4th at like 142mph@8500 but my gsr tranny maxes out in 4th at like 128@8500.... trap speeds are like an estimated speed between the last 30 feet of the 1/4 mile... so when my timeslip says 120mph im really crossing the line at like 126....unless i get some taller tires or up my revvlimiter (which i dont really want to do unless i get some valvesprings) i dont think im going to be able to trao much higher right now...

Well the 121 speed was with the B20 at 13psi shifting at 7200. The fastest trap i pulled ls\vtec was 118 still running a 12.1 but with a slower 2.0 60ft.
