SWEET! I've been wanting a twincharged and Hahn (even though they're great with straight turbo) really dropped the ball on it. I think ZZP is going to make a killing from those of us who've been dying to be twincharged.
I can't give up my SC (I love the whine, instant power), but I would also like the benefits of turbo in the higher rpm ranges.
Any word on pricing/when this will be available? A link would be ****.
Saving up for this since my warranty's up anyway--SUBSCRIBED!!

if someone said it couldnt be done its because they are retarded. In reality 99% of the time its not really worth it. A properly sized turbo will give you the same gains with a very similar power curve. Basically all your doing is making the turbo spool faster, the highest amount of HP the engine can make is always going to be limited by the device that can push the most air, in this case the turbo.
Lets say the turbo is pushing 15 PSI, that 15 PSI of air is the most the engine can take in. IT doesnt matter what the supercharger does because its air is fed from the turbo. So basically the supercharger is compressing/passing the air through and doing little more than causing parasitic drivetrain loss.
While yes the supercharger will make the turbo spool faster, but that really isnt a problem with less than 400WHP. The turbo should be able to spool in pleanty of time. Now if this kit was put on a full built LSJ that revs to high hell with a big ass turbo, it would be pretty badass. As a full on HP monster this is cool and worth it. But as a street application its not really worth it.

In the 3800 market the cars come with roots blowers. We've had turbo kits for years. The twin charge GP we did went 9's in a months time. Power is smooth with no turbo lag. The larger the turbo you run, generally the more efficient it is and the more power you make at a given psi level. In other words this kit allows us to use a large turbo and still have instant boost like a blower car (actually a little more). At 15psi our kit will make more power than a typical stand alone turbo setup at 15 psi or a blower at 15psi. Plus by playing with pulley size, boost levels, and bypass opening, you can tune in whatever power curve you want.
And most importantly, I think you're going to really like the price considering what all you get with this kit.

what about cooling. is the charge air being cooled by the stock intake manifold intercooler??
I imagine you could use all the cooling mods out there, CX front mount, dual pass/option B, would that be enough or are you guys using an intercooler??? and if so do you just utilize the stock H/E?? by that I mean obviously if you intercool the Turbo you wont use an after market front mount for the S/C, hmmmmmm, please go over this lol

You haven't driven one then. A turbo always has lag unless it is sized small enough to limit top end HP. We made 350ft/lbs and 350WHP with ease. I'm not sure those numbers can be combined and met with either a turbo or a blower.

Yes it does make for an amazing track car, and 350WHP is nice. How daily driveable is the car? I think this is a great product for a track car, but daily driven seems a bit uncontrollable.
There was someone that did this with a jbody cavalier a few years backs. How much boost is the kit pushing at the turbo and then after the supercharger? Cause the way he had to figure it out was first figure out how much boost the turbo was making, then calculate how much the supercharger would compress the already compressed air into a higher PSI.

IDK I think the turbo alone wouldn't be far behind. and you wouldn't worry about that 60hp added stress on the internals of your motor that having the SC adds.
I will be as bold to say that the engine would be better off and the car make more power with the same setup minus the sc.

Nice what about if we wanted to drop our car off to you guys for you to do the whole thing? Is that possible? Cause you are what maybe 2 hrs south of me
