OK, I need some ideas/suggestions. My mods are in the sig, but I have a huge problem with traction. Besides running full slicks, What are some good traction mods out there?
As the majority of you know, I ran a 13.79 with my stage 3 set up. The time is because of no traction in 1st or 2nd gear. Take note that this was my last run of the day, after running about 3 back to back runs during the LA Invasion at Fontana. I was running 14.4 @ 99mph without the 50 shot. Here is a cheap recording of the Cobalt at the track.

Note: You'll hear the DR's screaming for help as they break loose. Im heading back November 1st or 2nd, but I want to make sure I get better times on the board.


I've raced V8 RWD vehicles since I was 17 (now 28) and mastered it well. FWD, I just started 2 years ago, and it's a whole different ANIMAL.

Thanks Guys for your input!!

 

can't you guys regulate boost in 1st through hpt? You spraying in 1st? what size/type dr's? what rpm launch?

 

These threads might be useful:

How to launch fast.
How the F do you launch this car

Also, maybe you could consider limiting boost in 1st or installing a WOT Box.
Check the various threads on these topics and make up your mind.

1. Can't do anything to the PCM, it's locked (it"s the GMPP one)
2. Yes. The PCM will spray in 1st. 3.5~4.0k thru 6.5k. Thats why I crossed in 4th gear.
3. BFG 225 40 17 Drag Radials on 17" ION Redline rims. 20 psi
4. 2000 rpms, riding the clutch till the rpms reach about 2000 without riding it.

Cool thanks!!

 

i would no put a bottle warmer on your bottle. let it go to 650-700psi. you will not spin in 2nd if you allow it to get cool or go that low. if you don't have a pressure gauge then buy one at dynotune.com for $25 bucks.

through first you just need practice babying the car and not WOT. once you click into 2nd give it hell. floor it and pray you don't spin. when my bottle pressure is low on a 40mph roll i don't spin. did this last night.

once i put my heat in my car for a while almost got it to 900psi. i spun all through 2nd. sucks controlling that much power.

are those all your mod's in your sig? anything else maybe i could try to help you figure out what to get.

 

1 word

practice, you has it or not

 

Mounts help, but its hell on your tranny. I ran a 13.6 @ 108 mph with stage II, intake, exhaust, and downpipe. (on street tires) I for see you getting better times with a WOT box, mounts, and run a 16" wheel with slicks. Get stage II drive shop axles if you don't already. I would also invest in cooling mods (which has nothing to do with launching) but will help you out in the long run.

 

If the pressure is at 600-700, I won't feel a thing. It has to be at 900-950 in order to feel that sucker kick hard.

Those are all the mods. Should I run a lower PSI on the DR's? This way maybe I can spray in 2nd with no wheel spin.

Yes practice is a must. But The 1/4 mile track buy where I live at open once in a blue moon, so it's hard to practice. And when you do go, it's so crowded, you'll get about 2, 3 or 4 runs if you're lucky. The last time was a private event, so it was limited to 150 cars. On a TNT night, they are limited to 500 cars.

But, I'll keep trying whenever I can

Good time for street tires! I'll look in to cooling mods later. Winter is right around the block and playtime will be over soon.

 

if your spinning through all 2nd like i do when my bottle temp is high. keep in mind i am on stock tires. you should lower your bottle pressure it will be a smaller shot and not as powerful however if it doesn't kick out and you don't spin.

traction getting grip > spinning

those are my thoughts. i street race the crap out of my car. talked to joe last night on the phone told him what happened with the 2 srt-4's i raced last night and for the first time having my temp to 900. spun all through 2nd and lost. re-raced the same car was a car in front cause it was lower bottle pressure and didn't spin. both were at 40mph. if the temp is up rolling 60mph you will not spin in 3rd however you shifting at the track into 2nd then spraying automatically with stage 3 ecu it will spin too much. it is worth a shot

 

I'll give it a shot. Did you get those races on video?

 

Three little letters....

R.W.D.


Sorry I couldn't help myself.

 

no i don't have a video camera the one i used to use which was sick is my sisters. i raced my friends 60trim srt-4 he got it back but only running 750cc injectors and 15pounds of boost and his wot box isn't working exactly right. also a stage 2 srt-4 with 300whp

 

are there any 1/8th mile tracks near you those are great for practicing launching

 

More suspension mods if it hasn't been said.

 

lol little bitch my bottle doesnt go below 900psi in florida. heat it up to 1150psi and see what it really does(**i wouldnt recommend it. lol). i pulled a 375awhp evo9 by almost 3/4 of a car

 

last night i ran my buddy with a 60trim we guess maybe 360whp? 750cc injectors and 15pounds of boost. ran a 380whp srt-4 and a srt-4 that dyno'd 425 with race gas but wasn't on race gas. he was maybe 1 car to 1-2/4 cars behind them.

later him and i on the way home did a pull i was 2 cars in front from 60mph and bottle pressure was at 700psi. once we hit about 140 he was right behind my fender. assuming he lost by only 3/4 of a car.

however his car should be up to 20psi and close to 400whp. some how my car is only i am guessing 310whp range idk i really think more and my car some how pulls strong on the road and no clutch slip i just don't get how and why i always win or ahead or tie with cars i never feel like i should be.

also his friend once we got home i raced him a 300whp + srt-4 i pulled 1 car on him with the bottle pressure at almost 900. spun through 2nd him and i both at 40mph and i was 1car ahead. then we re-did it and i spun then let off shifted early and he was 2 cars out on me then i pulled in a little closer and he had me by 1car. should of re-done it at 60mph. maybe soon again however none of us have video camera's and i think cell phone video's are almost the same as trying to explain it.

 

I hear ya, I own other rear wheel drive cars, an 06 Trailblazer SS, an 04 GTO and a 72 Ventura. These cars can hook with a pair of drag radials.

You know how to drive your car. I raced my brother's girlfriend, she an 05 gto, against my 04 gto, both are auto. I ran a 9.1 in the 1/8th and she ran an 8.8. My gto = stock and i had 87 octane in it. Her car has bolt-on's + a Dyno tune. She made 380HP and 379 TQ to the wheels. Driver counts for a lot.
