let me start off first by saying that I am in Germany 1000ft above sea level. track that I race on it made of concrete in segments up hill a little. no traction even with 24.5" slicks. most people raced in the states say its a 1 second difference, if you run 12's in Germany you will run 11's in the states.
my car 2.0l ls/vtec peakboost kit 450whp . 95 civic full interior.
last year I ran 12.1 using a b16 transmission with a sc61 at 20psi.
this year I have a ls transmission long gears,
I am very frustrated with my performance this year because my best time was 13.17 seconds @ 198 kph trap spead. I don't know what measures to take to improve my launch, and 1/4 mile times. season is over, so I will frankenstein a transmission for shorter gears,
the funny thing about all this I don't lose.
any tips that might help me improve is greatly appreciated.

 

what do you run your tire pressure at?

 

12 psi on the slicks

 

get a gsr or b16 gearset in there,rev limit @ 10,500, drop slick pressure to 6-6.5psi, launch around 7k with 5 psi boost pressure.

 

I launch at 6800 rpm with 6 psi in M&H 25x8.7x13 and I would run the b16 or GSR tranny take the LS out

 

I just got offered a b16 transmission, so I will begin the frankenstein next weekend,
I usually launch at 6000 rpm using the s300 antilag, the next time I have a chance to race is october 5 hours away. but better track. hope I can reach my actual goal of 10 seconds. 600whp

 

drop the tire pressure in the slicks.(I have seen as low as 4psi hot) I dont think that the ls tranny is killing you. I usually went faster on ls trannys then anything else. is it falling out of boost between gears? are you letting off the gas between shifts?
600whp should get you deep into the 10's!

 

I ran an 11.21@131 with only 340 hp

 

its a different track, and different altitude, it won't be the same from what others with experience here told me it will be whole second slower than stateside.
my gears are way too long. I have a rev limit of 9400rpm, and I finnish the 1/4 mile in 3rd at around 8000rpm.

 

Altitude sucks.

At 550ft above my 280 whp went 11.200@124.

I feel for u lol.
