Hey guys...as you can see with my mods below I should be running in the mid to high 8's...and I ran a best of:
R/T...1.625 (first time ever at a track)
60'...2.303
330...6.073
1/8...9.171 (against an SRT-4 (9.560))
mph...79.35

I can get traction for crap! I am peeling out until 35 mph AND I am easing into it...Do you think the problem lies at the line? Because, I know my car has so much more potential...ANy suggestions would be greatful....(Rear tire pressure was 36lb, front = 24lb Street performance Hancock Ventus tires...

Your launch sucks as bad as mine does. Here is a ZZP article that has helped me a little bit. Also, what tires are you using? That can have something to do with it.

Without your cam in you'd run a 14.168 in the 1/4 not to shabby with a poor launch it will come with experience both reaction time and launch techniche.

Also those hankook ventus are not the best for traction, especially in a car liek these that don't liek the t word. Are you heating the tires before you launch or anything? this can make a considerable difference as well. My buddy has the hankook ventus on his stang with a 5 spd 4.6l and he blows those things off of it all the time and he is stock, he will burn em off the line second and breakem a lil in 3rd. Get a good tire and that could help, i liked my gforce kdw but they where loud on the highway but would handle and hook like a dream. Also had the kdws on the factories for winter and they where nicer for everyday. the eagle f1 gets good reviews but i don't like goodyear so i will never run them but have good revews at tirerack.

there my 45 cents worth

I have heated them...but I read a site that's it's not good to heat them for a FWD especially for street/performance tires...so I will try without burning them Friday...

I went back to the track and ran a very consistent 9.4 1/8 mile...I KNOW that I can do better. I can definately tell that I need something to help with traction...traction bars..adjustable struts...SOMETHING!! HELP! I know I'm putting out at least 315 HP and I need to back it up!

With your mods you would dyno around 225whp+ 30% at the crankyou need headers and a cam to get even close to 300hp I see you took your cam outa your signature what happened. I suggest 1-9 rockers an easy swap and will get you closer to your goals.

hmmmm...you're not making much sense to me, considering 225 hp+ 30% = 292 HP...I would take that as being close. Oh yeah, I just haven't installed it yet...that will be a weekend project and I don't have the time right now. I can't believe with all of that stuff you have, that you're not putting out over 300 whp...

the limited slip differential from thrasher is well woth the 500 bucks, that is one of the biggest performance robers in our cars. also get a pair of slicks from the front, with your mods you`l be seeing mid to low 13`s

You need to put your car on a dyno a stock gtp is about 195whp i am not trying to put your gtp down it's just you don't specify what hp your refering to whp or chp by the way 272whp translates to around353 hp at the crank also i did see trac bars on a site i just can't think of it right now i was just trying to clarify your claims I also simpathize with your launch difficulties one other thing i'm dynoed at 272whp without nos i've yet to get back on and spray .By the way good luck on your cam install it's quite a job but well worth it smile

I know...I meant 300 WHP...but, then I realized that you have a GT...anyway...I've seen the traction bars...anyway, I believe my problem can be solved by the suspension package from ZZPerformance...looks pretty nice...set my rears to firm so I don't get so much weight transfer...I'll get the cam in...anybody know how to post a video? I recorded my car at the track on one run...too bad the sound didn't come through...

GDGTP, you are running a 3.25 with out headers, P&P mani's, cam or rockers. I would bet you are getting some KR with your setup. I would also be willing to bet with your current setup a 3.4 would get you more HP.
