Asphalt Assault

Oh my god end of the month.....LOL hanging on to the 3" exhaust! or will 2.5" be enough?

chevysalesman614

it is general forum concensus that a 2.5" exhaust is acceptable for the stock s/c.(even with smaller pullies)
MOST turbo cars go with a 3" to allow the turbo to breath a little better. i assume this would also apply to a 350+whp turbo cobalt. (back pressure is the enemy of any turbo build)

Asphalt Assault

Well I can atest to 3" is overkill for SC modded car with 2.6 pulley and 60# injectors. 2.5 is great. I went 3" for the 350+ HP build. but thought I would go LNF. now that I have not got rid of my SS/SC yet and this build is becoming real I may keep it or get another LSJ equipped with G85 package. then keep at least the catback. thanks. I always heard and felt this way but it is nice to get confirmation from the creator of this kit.

dude, i'm just a guy from jersey that likes cars, and used to have a cobalt... i'm not Bill Hahn.
IMO, LSJ turbo>LNF. dont sell your car for the new SS. your higher compression combined with a turbo will be pretty potent. Plus, from what i've heard, the LNF cars are a tuning nightmare.

Asphalt Assault

LOL I know who you are. I was talking and replying to bill and you jumped in LOL. and lower compression with turbo = better for High boost but 9:1 wont be bad. as far as LNF vs LSJ yeah you could be right. But what I want is approx. 350HP. the power band of the LNF is a turn on for me. so much torque and at 2G's. but there is a GMS kit that will boost power to 290HP and 310tq. I am not sure how I will go. LNF would be easier and actually I should have a car with full warranty due to how much time I have on my hands which is not much. we all have different motivators to making decisions in life. I dont have the luxury to time to tinker with my car. I have a family and I am commited to them above just a car. that is why I would consider a kit or just a new car. but I am watching a local turbo his SS. if he has great success then I just might pay him to do my car. He would love it I know. we'll see which way I go. I like having a new car though..... LOL thanks for the advice but I know alot of what you said already.

Ah yes! Different strokes for different folks. This is why I love this market so, with both factory and aftermarket forced induction...there's something for everyone, whether they want a 'turn-key' solution or a 'turn-wrench' one

chevysalesman614

SSnipes? name change? my bad i didnt know. i thought you we're talking to me. i didnt want people thinking i was speaking for bill, as i am far less knowledgeable. i merely offered a quick response, to a screenname i didnt recognize. i assumed you were a noob, and needed guidance, i rarely look at post counts(or signatures) these days.

from what i remember bill said the super 20g setup produces boost low in the rpm band and is similar to the feel of an s/c'd car, yet gives you more of the "seat of the pants" feeling that impresses the ladies
i think the hahn kit will make you happy. have fun.

Well just a little update for you guys. The car went back to Bill Hahn today so he can finish his work on the fuel system and then over the weekend me and a buddy will be going up there to put in the neutral balance shafts. Then it will be dyno time and video time for everyone waiting!

haha but it still says supercharged!

BlackSS/SC

Can't wait to see the results!!!!

2K5SS/SC?

Nice! Can't wait to see what she nails down for power!

Damn....!

Hahn does and Awesome job.. Wow...

Awesome Car man...!

Hahn RaceCraft

But it IS supercharged...turbosupercharged.

Actually, that's the technically correct adjective! It means supercharged via an exhaust-driven turbine. Of course, 'super' means more than normal, and 'charge' represents the airflow into the engine. So, yes, it's still a supercharger!

Over the years, the term morphed into 'turbocharger'.

That's today's nearly useless triva fact, folks. On to the BOOSTING!

We expect to have some initial results next week.

I thank you. Joe thanks you. Now let's make some SICK POWA!

Best of luck...

hey bill, not trying to thread jack, but do yall make a turbo kit for a 2002 Z24 Cavilier with a 2.4L?

Hahn RaceCraft

We do not...we did not pursue the TwinCam engine in Cavalier/Sunfire, just the Ecotec and the LN2 2.2.

r0k0

hey will the the topic.. do you think you can make a twincharge for our cars..?

i like the idea of the supercharged pushing in the engine and turbo.. its a Turbo guys best dream.. a non-lag turbo power asking goddes of sex pleasures :P

haha sorry for that..

think you could make one..?

if yes.. then i'm saving my car and bringing my car to you guys haha

PuSha050

they already dropped that project a long time ago and decided turbo only was the way to go

Kennyspec

Hey Bill, how much for that intake manifold?

spaz

They already built a twin charger kit. I don't think it worked that well. It was on the desired cusotms cobalt. Keith took it off and sold it to someone on the site when he put the car back to stock.

r0k0

wasnt it good..?

hey Bill give me a call when you see this.

articzap

Twincharging in the Cobalt using the stock blower is very inefficient and not a good way to make power. A properly size turbo or supercharger upgrade are way better options.

Hahn RaceCraft

We are offering them at a special price for Cobaltss.net members:

$750 while supplies last. The price will go up once this initial run is sold.
