actually, the hahn kit on the 2.2 running 8-9psi is suppose to be good for 200whp. Plus...reeper...no one said with this kit running stock boost we would ruin an ss...like redbasebolt said....it'll give the ss some competition...a 200whp 2.2 vs 220ishwhp ss would be a good race....if both were good drivers

 

YES! Finally have a forced induction kit to look forward to.

 

I'd be really excited right now if I had money for this. Better start saving up I guess.

As far as twincharging, the most practical use I've seen for it is for the blower to feed into the turbos so that they spool up faster.

 

however the 2.2 is going to produce more torque which will give it teh win

 

Bingo

 

+1

the shorter gearing, though it isn't a huge difference, is going to help a bit there as well

with a good driver it will run with, if not be quicker than, an SS/SC that's stock, if not maybe mildly modified

not sure why some of you can't understand that

 

you'd smoke those crappy tires on idle lol

 

I think you 2.2 dudes should supercharge your rides first seeing the gm supercharger Fits 2.2's ITs makes sense cus you get over 200hp then you can always Twin charge later if not the ss/sc guys will alwyas have you beat

 

Thank god.....me wants more power

 

Im going twincharged as soon as the kit comes out...with the twincharge kit, stage 1, and other add ons ill be pushing waay over 300hp. I just hope Hann doest back out on the project.

 

This thread has been fun to read, and people are mostly following the rules. I do have to add what I can however, lots of wrong stuff. I met with Bill about a week ago and here is the latest news I got straight from the man himself.

The kit for the 2.4L is for the Solstice. It would not work on the Cobalt. It is available right now.

The LSJ (2.0L) turbo kit will be ready first, before the L61 (2.2L)

The LSJ kits plumbing takes in fresh air to the turbo, intercools it, then to the supercharger, then to the engine, all in series.

The L61 kit is current being held up by ECU tuning issues. They have been delayed by the people providing them with the fuel maps. They shelved the L61 to work on the Solstice and the LSJ. Since those are done, they can now work on the L61, so it shouldn't be much longer.

Even without that, they have already successfully made 240 WHP on an L61 Cobalt (the JIN Tuner Transformation car)

Given the same amount of horsepower, the engine with the larger displacement will produce more torque. SOOoooo.... An LSJ with a stage 2 kit making about 240HP should get beat by an L61 making the same horsepower.

Okay, I think thats all I got for now.

 

Have you even looked into your own engine bay? Supercharger is bolted to the intake manifold so no piping for the turbo to go directly into.

 

Sounds good, all except the 2.4 part. Makes me sad. That was my summer plan.

 

If they don't come out with a coblat specific 2.4 kit the solstice should work with just a little fabrication. Its stupid if they don't. Not alot of R & D would have to go into since the sol kit is out and i know alot of people would be in line for it.

 

I'm not sure why u would say that.....this kit from gm has been talked about.....its gonna be over 3g's for the kit for around 200 horse....not wheel horse....but at the flywheel....definately would get beat by a stock ss/sc. The hahn turbo kit should be around 3500...and would give the 2.2 around 220-230whp....upgrade the internals...up the boost....more power than that supercharger from gm could ever make, much better deal in my opinion. As for the twincharged kit.....its a great idea but I think it'll be hard to get alot of power out of this using the stock supercharger. Like NJHK said....the supercharger is going to limit the boost from the turbo...it'll restrict it....it is a roots type charger....bolted directly to the intake manifold...how is the turbo going to help the supercharger like some of you have said????The turbo isnt plummed to the supercharger. Now if it was a centifugal supercharger like one from vortech or a procharger...where the turbo could actually be piped to the supercharger...I can see this working well.....but tuning on it would be crazy....along with cooling both FI components at high boosts....

 

right

also, you don't add boost pressure together, you would get the highest level of the two since it would sustain (or at least try) that pressure over the lower one

Bill is a great guy, I talked to him for a while last year at Nopinationals. He helped give me a few ideas and clear up some questions I had with things at that time.

 

How many of you guys are actually considering buying either of the Hahn kits? I'm a dealer for them and would love to get a big order in all at once and maybe help you guys out with pricing. Anything to finally have a Cobalt finally give me a challenge

 

Oh and if you guys didn't already know this...I'm Hahn equipped personally. The time in my signature is with the HRC Stage 2 Ecotec kit with 40# injectors and a 6:1 FMU calibration. Those are the ONLY 2 changes from the basic kit. Shows you really well what's possible.

 

when do you see yourself getting these in, i noticed a while ago you had them as available and in stock...or am i confused

 

I'm getting one either way, it all depends on what kinda deal we can get for a group buy I guess.

 

i think i still need to be sold, the only hahn product i had, i had problems with, and it was only a manifold.

 

I have 0 in stock but I have been told I can accept pre-orders for them.

I can't by HRC's rules run a GP on their products but I can cut my profits to get more people into the addiction I won't be able to publicly post any prices though just because of fair pricing rules. I'll let you guess know when I have a price though.

Roadrunner: You do know HRC has a 3 year/unlimited milage warranty right? If you have issues send it back!

 

Can we start a list of interested parties or is that not allowed? I would love to know what kind of interest there is so I can start working out some pricing options.

 

Clutch yes will definitely burn up. GM says the pistons wont be reliable enough. but that is GM and they will be very conservative. I would change the pistons for it is not much money compared to an engine, But it may not be necessary.

 

As I posted in another thread...GM's piston and rods numbers are way off. I've gone way past them. Heck I'm still on a stock clutch, flywheel, and axle setup too.
