I figured since I became the 1st turbo 2.4 on the boards here that more people have become to be turbocharged and we should should have a thread with just turbo 2.4's to discuss whatever turbo related. Post what setup you have whether it be hahn's, another vendor or custom and also post your 1/4 miles and dyno numbers. Should be useful to those thinking about going turbo. Please make this a sticky. Thanks.

2006 Cobalt SS 2.4
Automatic
Hahn racecraft Turbo System
Wheel Horsepower on Mustang dyno: 234
Wheel Torque on Mustang dyno: 244
1/4 mile: 13.7 seconds @ 104 mph

Over the next month my numbers will be going higher and I will update this post with the new numbers.

Everyone else please follow suit.

 

nice numbers you got there. i hope you fix the boost issues......also i can't help but poke fun a bit...... but if you were NA you wouldn't have any problems

 

2006 Cobalt SS 2.4L
Automatic Sedan
HAHN Racecraft Stage 2 Kit
Wheel HP/TQ: Unknown
Best 1/4 Mile Time: 13.56 @ 108

 

hmm i though pzazzz was the first turbo 2.4 nice numbers guys .. we need to start punching up the boost and making big numbers

 

nope, in fact he was with me when i got first dynoed then he made his kit after that and later had too many problems and removed his kit. if you look at his thread dates and my thread dates youll see i was before him.

 

ahh so i see i just heard about his first lol

yea i heard about his problems i thought he got it smoothed out but sold it anyway meh whatevers..

cant wait to see your new numbers

 

thanks, my new numbers im shooting for are in the 300whp/wtq range and low 13's. Within the next month i hope to be retuned and ready to hit the track again but itll be hotter by then so my best numbers wont come till the fall i guess. this should be with 13psi

 

cool i think you'll be able to get better then low 13s if there's good track prep

 

sorry but id have to say your are second....your the first hahn turbo...but ppazz was first to turbo...once i get mine done im pretty sure ill be the only custom setup on the board

 

haha we already went through that haha .. readin =fail for you and nope you're not even the only custom setup 2.4 on here .. i know there is one that doesnt really post but he's a custom turbo 2,4 if i remember correctly

hehe you'll be the only custom ACTIVE 2.4 turbo on the boards

 

ehh oh well....me no likey reading sometimes....maybe perhaps 2.4 with the most power? i dont know it doesnt really matter im just happy 2.4's are finally starting to break into their potential. Whish btw, that reminds me. I dont believe any known 2.4 on the board has broken 300whp. i wonder who it will be

ive talked to him a bunch of times and the only major problem i remeber him having was the turbo was defective. after that the kit never made it back on the car. what problems are you talking about?

 

well yea over 300 whp you might have.. if you dont count hahn

there's somenoe on here with 300trq about and almost 280 whp on a 2.4 ion least i think he's on here ..

 

im not sure on the other issues. i thought i heard him say something about an exhaust leak maybe but there is a pittsburgh cobalt click that he is in and they wont talk to me anymore for unknown reasons.

Just to put to rest the argument of who was 1st turbo charged in the 2.4 community:

Fail.

My tranny is going in within the week along with some other goodies.


I'll be sittin at about 350whp

 

cant wait to see how that tranny performs with that power. good luck.

 

Howdy lol im not a cobalt but as of tomorrow i should be at 300whp, putting the clutch masters fx300 clutch and fly wheel in with a bunch more goodies. Will be running at 14psi tomorrow night 8). G5 GT 5speed if your wondering muhaha.

 

who has a custom turbo kit? i was planning on supercharging mine this summer but im now thinking about turbo cause i hear you can get a lot more HP out of them. just seeing whats out there, dont want hahns kit either.

 

if your going to be doing that on the hahn turbo youl be close to or maxxing that thing out

 

The HAHN kit will serve as a base.

Im ordering a significantly larger turbo, that still has great spool up.

I wish the car to be at 450whp-500bhp when im done.

Now, the 2.4's have been pushed over 400hp fine. but i dont feel like givin out thousands for custom 2.4 internals, since i just forked out $7500 for all my other goodies.

 

looks like with that power you should be the fastest 2.4 on this site. my 300whp wont be able to rival you ha ha!

 

You gotta figure, im also at a disadvantage over yourself.

You got a coupe :P


Did you ever get your 300whp?

I'll keep modding this car until I blow it up, i'll remove the turbo, then sell the kit, and then trade in my car.



Last night at the drag strip my car was thrashed..i had an easy 200lbs of baby **** in my back seat/trunk that i just left in the car.


I had to throw a blanket over it all, so the techs wouldnt see it and bitch.


im still debating on going with a AEM standalone system so i can tune per psi of boost.

Im tired of drivin in Drive...and if i go into boost it bogs down the car (since the thing kicks up to 70psi at 1psi+)

 

no, i didnt get to my 300whp goal yet. im waiting on my 60# injectors to come in then I will be hitting the dyno once again and hopefully not having any tuning issues for a long time after that. With 300whp i think i will let it be for a while till i pay the car off then maybe i'll build a monster with the tranny and forged stuff.

 

Was talking to HAHN. he said 12-14 psi should put us at 290whp.



Did you increase your fuel pressure as well?

he said 12-14 psi should be at 90psi of fuel.

 

yeah i maxed out my fuel pump on the dyno with my 32# injectors, im putting in 60#'s so hopefully i'll have better results. I should be running 13 psi but with the boost problem i dont know what is gonna happen when i fix it.

 

I have a friend with a Cobalt SS supercharged, but he is looking to take out the supercharger, and going to turbocharged, and he wants to put out at least 600 hp, can someone help me and lists all the modifications he need to complete this swap and get the horsepower
