Bad 1/8 mile times

[funkbuster]

Hey peoples. Went to the track tonight (Farmington). I was running pretty bad. It was about 83 degrees outside. I have a 1993 talon with 3"DP, 3" test pipe, and a 2.5" pipe from test pipe out the side infront of back tire, I am also running a SBR MBC. My car boosts about 12 or 13psi until around 4500 then it shoots to about 15psi. Rest of car is stock, acording to logger, I am maxing injectors about about 6-6500k. I shifted my car at about 6500 each gear and best I could manage was a 10.206. My brother's eclipse has run a 9.8 last fall, and my car walks his pretty bad. What could be the cause of my slow times? My 60' on the 10.206 run was 2.715 I crossed line at 74.963mph. I cant seem to find a good launch, I either launch too hard and spin thru 2nd gear or bog and almost cut off the car, which I did on the 10.206 run. Run before that one I launched and spun thru 1st and 2nd and ran a 10.949 with 2.8 60' at 73.232mph. I checked compression about 2months ago and was at 150 across the board, is my whole problem my horrible launches? How can I launch a 5 speed fwd TSI good?

Also have a pic of time slip for reference. I am car number 10.

Thanks for help

Your 60' is your problem.
No offence but 2.8 is pretty horrible, my 100hp fwd Jetta does better then that (on the 60' anyways )

I know that 60' is horrible, and believe it to be my problem. My friend ran a 11.2 in his 91 accord stock with exhaust and he was spinning off the line and his 60' was 2.4. I am just wondering what am I doing wrong to bog to the point where it almost dies, or spin like mad, it seems like there is no in between. My brother's eclipse has ran a 9.8 at that track, it just has dejon intake pipe and k&n filter, and exhaust unbolted at Dp, but still pushed together, just unbolted so when he gets on it, it separates a little and opens up, acutally works great. On the street I have walked that eclipse many a time, with my boost set lower and before I got my dp and test pipe.

try holding the rpm's at 3000,then ride the hell out of the clutch, once you start going, let it out slowly and you will either spin, bog, wheel hop, or get perfect traction, i always got the best launches with my old fwd this way, the weel hop and the perfect traction were the best, the wheel hop told me that i was just barely on the edge of traction/no traction. Its definatly not the slip/dump like you launch an awd, its more of a ride ride ride...wait wait ok let it out. At least thats how i launched my car, my buddy had the exact same gst as me and when we used to race he'd spin his tires and leave my R/T wise, but id have a car length on him by the top of first gear because he spooled up and really didnt get any traction, while i didnt give it all it had right off the line but waited a sec for it to get going before i punched it. Also, stay about half-3/4 throttle through first, 3/4 through second, and hammer it in 3rd.

ok, I will have to try that. My cousin said when he ran the 9.8 in that eclipse when it was his, he was doing the ride the clutch for a while then dump it thing. I will have to try that out.

Check the pressure in your tires as well.

Get some slicks(10-12psi) and stiffin the rear suspension. Slip it out of hole about 4500 and let it ride. I used to be FWD.

I just slip mine untill about 4500 rpm. Just into ull boost then go all out with only slight spin around the top of first. I just shift at about 6k to keep from spinning at the top of first and pulled pretty decent Saturday night. First time I've had the car at the track and I pulled a 9.877 1/8th with a 2.318 60'. Hold it at about 3000 untill the launch then give it a little more gas as you slip the clutch out. that works decently for me anyway.
