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.

Well, I plan on putting this cam in within the next few weeks..just need to buy a gasket set and find the fuel line tools and harmonic balancer removal tool....then I shouldn't be getting any KR hopefully, but I don't think that's my problem...I know it lies with the traction...c'mon, 2.4 60' times...I peel out until 35, sometimes 40 mph

well, I had a run tonight and got great traction on one of the runs and:
R/T .568
60' 2.202
330' 5.979
1/8 9.093
mph 79.85

I also had 2 runs at 9.12, so I feel like I gained experience, but I don't think I will be under 9's until I get better suspension...Well, unless I get that cam in...then I should be near 8.75. You agree?

My best 60' so far is a 2.176. That is on stock tires. I think you need more practice to get that time down. Just do what I did and go out and pick on some rice or rustangs.

Looking good , what is your goal? your setup isn't ideal you need header's at this point more than the cam at least ported ex.mnfld's isn't your knock ratio through the roof with 3.25 pulley?but your definatly a quick study 2nd time at the track and showing that much improvment.

I've already bought the cam a couple months ago...so it will be better for it WITH the cam then without anything...I will have about $2500 in a month and a half to spend on my car, and hopefully someone can help me get the best upgrades for the money...Headers for sure and throttle body spacer...

Put a 3.4 SC pulley on there and I bet you will improve your times. That 3.25 is giving you hella KR I will bet my GTP on it! A guy in our local club has something close to your current setup and put on a 3.25 and had it scanned. He is getting about 12*+KR. I bet with your current setup and a 3.4 you are still going to get very mild KR maybe around 2-5* With my setup, I still get .05-1.0*KR and on hot days it can even get up to 5* KR around 60mph at WOT. KR is a horse power killer!

I would increase your rear tire pressure to 44 psi and your fronts to 30 psi. Do one 4-5 second burnout. Do not drive through the water. After stagging(sp?), press down on the breaks with your left foot and bring the rpm's up to 3k. At the green let off the break quickly and give it more throttle but do not floor it until about 1.5 seconds into the run, then give it all you got.

Not that i doubt your times but i don't think track times should be posted without time slips ,anyone can claim great times you need to back them up with proof.

Hey, how do you post a picture? I took a pic of my timeslip....you can go to my website to see it (www.cardomain.com/id/gdgtp) or http://images.cardomain.com/member_images/4/web/412000-412999/412665_15_full.jpg for the pic. If you STILL think I'm the one on the left or something, then I'll show all 40 of my other timeslips with matching Trap Speeds (78s 79s)

I was told the last time I went to the track (and that has been years ago) never to burnout street tires because the treads would hold water that would make you spin at the launch...a set of slicks will make a world of difference in traction...in conjuction with some of the other mods mentioned should make your ride a real rocket...and in this day of rice-racers its cool to see some modern US iron kickin butt!

Yeah Thunderbat...I heard something like that too, but it wasn't until I was doing the correct way to do a burn-out when I was getting faster times and better traction...the 8.85 run, my tires barely screeched at all...it felt so good...I appreciate the compliment and motivation to make my GP better...at least SOMEONE can say something other than dis-belief, etc....I should be installing my camshaft before July and headers soon after...July 3, there is an Ultimate shoot-out drag race at the MidAmerica Motorplex...you can win $300 for each class...

I have been told that you are not suppose to burn the street tires. Also heard to drive around the water box and do 3 very short burnouts to help clean the tire.

You said you raced a Neon SRT-4 that put down a 9.5 1/8 mile, mu buddies will hammer 8 flat all day......with slicks......Thats only if you beleive it tho.....You are making great improvements GD, Im glad to talk to you all about racing becuase i went to an autocross event this weekend and there was only one pontiac and it was a fiero. nothing new at all..To bad i dont' have susp mods i would run mine...
