what would it take to go 12.90 E.T.'s in our cars with stock tires and a street legal
exhaust? how much would it cost? skip.

A good tune and practice. Cost - under 500.

street legal is a vague term... pretty sure no performance exhaust we put on will be 'street legal' depending on how strict you wanna get.

more than just a tune ....


Tune - thorough
Catless DP
Modded Air Box
CP

Driver MOD

With a tune, weight reduction, the track we run at, this will be enough. Need practice tho.

-downpipe
-3" exhaust
-tuning
-intake
-PRACTICE

exhaust does little for these cars. Save the $600.

this was a loaded question. saw a guy at the dragstrip the other day
run a 12.95. talked to him and he said all he had was a catless DP, muffler delete,
short ram intake, and a trifecta tune. i was like wow. skip.

Driver mod, learn how to launch. Your 60 is crucial.

Look at my sig, that'll get you into 12's. Tuning is the most critical however.

You and me were talking. I took off the short ram, was making fuel trims all messed up. I have since threw slicks on the car and am knocking on 11's. I am telling you with a good tune and practice, running at Norwalk witch is a top 10 in the world track you will be able to get 12's. I just watched a srt 4 with just over 300 wheel horse and alot of weight reduction take the world record stock turbo ET of 11.82.

I say stay away from any of the intakes at the moment. Tune, catles dp, and driver mod will get you there

yeah, I don't have the intake on .... yet. We'll see how it acts

hi cmiller. what kind of slicks you running? did you get your new trifecta tune
worked out? you were having some problems that day. or was it the short ram
giving you issues? skip.

I believe it was a little of both. However we are getting there on the tune, Vince is on vacation or it would be done, but is close. Where going to add a little more boost yet and hope to trap about 114-115 even with the slicks. I have a 17 inch wheel and a 26/7-17 motorcycle slick.

motorcycle slick. crazy.

Ha, its OK. It has been done for a long time.

Any high speed stability problems? Are you using the stock wheels and tires in the back with the slicks?

<<< 12.95@ 116 here.... Tune, Charge Pipes, Catless D/P, and custom Intercooler. On street tires

Any high speed stability problems? Are you using the stock wheels and tires in the back with the slicks?

Yes stock rears, I am not having any problems with them. There are no load ratings, or speed ratings on slicks they are all made the same. Also there are two compounds in a motorcycle slick, motorcycle compound, and a general use compound which is what I got.

I think you are Term. can be in the mid 11.80's with slicks. You guys need to get a set and go run.

Yeah, a good 60 foot plays a big role in getting in a good run. I'm hoping with the supporting mods I have and a good 60 I can try and crack into the 12's when I hit the track thursday. But I will be on street tires so it'll be a little tricky.

Do not use launch control. and dont shift to 4th if you have a raised rev limit. depending on how many runs you usually get at your track, and the amount of prep done, start at about 1800 rpms and slip the clutch out. if you dont spin at all, raise your rpms about 200 each pass.

Yeah, that is on my to do list... 17's with some nice MT ET Streets.... We'll see though!

Yeah, I've never used the launch control, I've heard it doesn't work the greatest. Cmiller, I am in the Dayton area in ohio.

At what light do you guys start to slip the clutch?
At what rate of speed do you slip the clutch?
At what point do you go WoT?

I've noticed that no matter when I go WoT with JUST my Trifecta tune I break the tires loose in 1st. Even if I don't break them loose on the launch, then go WoT, they start to break loose.

I have HPTUners... so I limit torque and boost in 1st gear with a very aggressive RAMP up into torque and boost in 2nd gear...

2nd to 3rd NLS still equal lots of tires smoke.

just have to do controled clutch slips... to keep power to the ground.

I went 12.71 at 114mph on just a tune and m/t streets (hot lapping). 1.7 60's all day!!!!

1.7's 60. I hope to god to hit a 1.7. If I hit a 1.7 I will run around a 11.8.

Dont worry about the lights when you are trying to get a good time. I never even got the clutch released fully in first when I was on street tires.

Sure, but if reaction time is .5 then how much does that take off of your overall time?

it doesnt unless your in a competition. which even then you will just lose but time will not be affected.

So just ride my clutch a little more on the launch to insure better traction?

Yep.

How fast is this going to burn my clutch up? I'm going to the track on friday. With a good launch I might get into the mid 13's ^-^

I have a tune only and am running a 13.081. I do have a motor mount, trans mounts, and muffler delete, but they don't do anything for performance. Should be in the 12's with the new tires I have.

Well you will get the feel of it.

hey miller, you ever go to 42? i'm thinking about going on tues. and trying
for the 100mph club.

I have not, and I hear it is junk so I wll probably never go.

I had dissapointing times tonight, I had to 13.99's, best 60' foot was 2.22, I'm getting slicks next year, screw street tires. I know I should be faster in the quarter with the mods I have. My car was trapping consistantly at 102-103. Track I was at doesn't have the best prep. Cooler, less humid weather needs to be here.

Why does everyone just default to slicks when their 60' time sucks? Why not learn to drive on street tires first eh?

BTW, my 60' times are 2.1's and I run a 13.0@110.

Oh, my comment wasn't made toward you, i have seen what you do, and it is good. Lol. Just these people that come in here and say, I could only get a 2.95 60' time, so fuck street tires, I'm getting slicks. These are the people that run 30 psi in their slicks, and don't do enough of a burnout to warm them up, and that shit pisses me off. If you can't drive, learn to drive before you go spending money on stuff thats only going to make you look cool.

No offence, but most of us don't have anyone to teach us. Generally slicks is the best route. I'm all for learning how to launch with the continentals. But i've also only been driving stick for a year. I do this for fun, not for competition. Which is why I've been asking questions about the clutch, etc.

No offense taken, and I understand where you are coming from. BUT, slicks wear on ALOT more than just the clutch, and I don't see the benefits of running slicks if you are just doing it for fun. Maybe my appeals differ from other people's, but I see great appeal in running street tires because it is a sort of disadvantage. I have set goals for myself, and when i meet those goals, i will consider turning to slicks. But, just because I have a shitty 60' time doesn't mean its time to move to slicks.

Long story short, I guess I am trying to say slicks are a bandaid. If you suck at driving on street tires, you'll suck on slicks.

hey miller, you ever go to 42? i'm thinking about going on tues. and trying

I live close by there and have been meaning to get up there with this new tune but just haven't found the time. Oh and the 100mph club...shouldn't be a problem for you...I did it stock.

hahaha. I don't really have money to buy wheels and slicks, sooo....Better get teaching ;)

Practice makes perfect! I went out my first time at the track and ripped off a crappy 13.8. I knew both my car and my abilities had WAY better than that, and with some tuning tweaks, and skill refinement (through 40 runs on the car in the first half of this season) am now down to a 13.0.

I stuck with cmillers addvice on working on my launch last night and it did help out quit a bit, a 2.22 60' is my best so far in the cobalt. They get lower everytime I go out, its just finding that right certain spot does take time. I'm not nls'ing since I am tuned after seeing the horrow pictures Maven posted up on a thread I had started, so losing a little time on the shift probably. Just need to keep at it.

Practice makes perfect. Learning how your track operates is the best too. I can consistently launch at 4k rpm, but your track may not allow that, or may allow a higher launch before gobs of spin.

Dunno. Havn't really tried riding the clutch at the track, so it's hard to say. They allow 5ki launches, which helped me out to slowly slip the clutch when I was stock. Too much power to do that now. I've gotten OK at leanching between 2-3k, but again, I've never ridden the clutch once I've launched. Won't be going to the track tonight either.

When we go it's more of a family event. Uncle has a 66GTO that he races and he bailed out on us. My aunt has an 02 Mustang GT and she T-boned someone a few days ago. Which leaves me the only one. Pretty sure we're going next week though!

Trying different stuff is the only way to find out is what i meant. Have fun, learn and get better.

Yeah, the track I go to isn't like norwalk in how they prep, that is for sure. Yeah, it takes practice, this track if I launched at 4k rpm, I would spin like a mofo so I just keep trying to see how close to it I can get to launch.

A little spin can be advantageous. Too much is bad. As long as you aren't wheel hoppin, let her spin a bit, obviously don't burn the tires off, but if it spins, give it a chance to catch up to itself. Also, what are your mods and best slip? 60' and ET?

Mods are in sig. Hahn 3 inch catless downpipe and exhuast, hahn charge pipes, hahn, intake, hahn intercooler, and trifecta tuned. Bests, 2.22 60', 13.99 at 103.01 mph, I trapped 81 mph in the 8th mile on that run.

if people are promoting sub 13s runs with just a tune, and maybe a catless dp... what would the GM staged kit run? What mods further perk up the GM kit? Has anybody actually bought this thing yet??! It seems like nobody is commenting on it!

Because it's not officially out. Trifecta tune puts down more power than the stage kit. and only costs 1/3rd the total price.

What did Maven say about NLSing when tuned?

AAHHH.. I thought it was out. Makes sense now.

So is the 290HP & 320tq confirmed for the GM kit? How is it making the power vs stock? Is there a mod that will wake it up even more?

It's for a business/company car so maintaining warranty and reliability would be really nice.

Since its not CARB approved yet, then, I doubt anyone has it installed. Some people have bought it, but are waiting on the CARB approved programming.

I've seen not to nls when tuned cuz the tranny can't handle all the extra torque. He posted a picture that looked like shrapnel and it was a piece of if I remember correctly, a chunk of third gear. My car only has 3700 miles on it so not trying to break the tranny on it.

I use it all the time.

I only use mine on the track now. I guess if the trans blows, I pray to god it only blows the internals and not the case, and I will be getting a new, cryo treated set in return, lol.

I have not, and I hear it is junk so I wll probably never go.

i know it isn't the greatest track, i been there. but variety is the spice of life. it's just cool
to go to different tracks and see different cars/people etc. you probably won't get your
best run there, but it's neat to say you raced there.

I live close by there and have been meaning to get up there with this new tune but just haven't found the time. Oh and the 100mph club...shouldn't be a problem for you...I did it stock.

so what are you doing this tuesday night sandman? why don't you meet me at 42??

Yeah, thats the bad thing about nls'ing, it seems the only way you get faster times when at the track, I was half tempted to do it this past thursday but held back. I might try it once next time I am out to see how much of a difference it makes in the quarter mile.

What did ya run?

Best was 13.99 at 103 with a 2.22 60'. Mods being Hahn offroad downpipe and exhuast, hahn intake, hahn charger piping, hahn intercooler and trifect tuned.

See.. Now I'm confused. how are some people running 13.99 with these mods, but others with just a trifecta tune are running 12.75? I've gathered that a typical stock time is around 14.1-14.3s @ 99-101mph. What would a trifecta tuned car with a catless DP run typically?

Its all in the driver.

My car with old Trifecta tune ran 13.4@106 with a K&N drop in.I will say, these cars take alittle skill and a lot of practice to launch.I agree with mkriebs,that just by throwing slicks or drag radials on your car your 60'ft times will be better. All the peolple I know that have tried this, after being terrible at launching on street tires,were no better on slicks or DR's

driver mod makes a huge diff

driver mod makes a huge diff

This is true

Yeah, driver mod is 90% of drag racing a FWD car. Hence why the majority of people prefer RWD... its easier to drag race. People criticize me for racing a FWD car, but what they don't understand is my FWD can still whoop their RWD cars ass.

i agree, i prefer to do my ass whooping on the street, where you can use you high hp fwd power,

the track does not reflect what a high hp fwd car can do, expecially on street tires

It can reflect it is the thing. You just have to compare apples to apples. I have a friend with a low 11 second SRT. Now, it makes about 500 hp. Granted, in RWD 500 hp would likely be a low 10 car, but were comparing apples to oranges there.

Yeah, our cars are beasts for top end power. Turbo spools up so fast if you're stock, and even faster with a tune. They're soooo nice. I can't wait till Vince can make the launch control changable.

quick question, how wide of street tires can you put on the front of this car on stock rims? 225? 235? 245?

What does it come with stock? 225? I looked on chevrolet.com and couldn't find it...

stock is 225/40/18, there are people running 245's but i think it all depends on your tire selection and setup

my next purchase will be 245/40/18 et drag radials i think


these street tires are useless in 2nd gear

Yeah, I've only been to the track 3 times with the balt so I am still learning much about the car on launching it. Even when I had my grand prix, even being a automatic, it still a few times at the track on how to get the best launches, I'd say it takes practice with any car. I just need more seat time at the track and I should be able to get my launches and times down lower.

On the front, I could most likely fit a 255, VERY VERY tightly. I have 245's right now, and one of the back ones got cut because my rear end is pushed more to one side than the other (brand new when i bought it, never wrecked, so IDK...). I will be flaring the fenders this winter so I can fit 255's all the way around... if not far enough to do 265's or 275's... this bitch is gonna be a track demon.

i hit 13.00 on psyko shitty tune so im sure with a better tune ill hit 12's no problem-0

but to OP i say tune, charge pipe,down pipe, good drivin in good weather if u still cant then SUSPENSION MODS thats what everyone forgets... or the pussy way and do a 50 shot or higher

I pulled a 12.95 with Charge Pipes, Catless D/P, and tune! :D

I could EASILY be a 12.0-12.2 with tires and the new tune for sure!

goodluck with that lol... ill give you a 12.5 if you mean street tires... maybe radials or slicks you can do low 12's

i hope u hit that with the new tune tho... ill definitely throw it on ASAP lol... then ill have to buy another intercooler after selling u mine lol

Yeah, I meant DR's or something along those lines....

:D
