Twin Screw Supercharger Conversion Demand

If a twin screw supercharger conversion were made available would you be interested in purchasing such a kit? I've been brainstorming with several friends who are in the performance field, and we're going to design a setup for the Cobalt in the sig. We were wondering if the demand is there to streamline the setup and offer it as a kit. Your opinions and thoughts are greatly appreciated.

1 problem, those who want to race the car in NHRA or IDRC can't run a screw type blower.

What exactly is a twin screw supercharger?

2009 Turbo Cobalt SS
traded in 2005 SS/SC

Dragracing is for fast cars, autocross is for fast drivers.

What kind of power gains are expected? How about price? Personally I would wait until people can fully tune the cars before releasing such a kit.

I think he is referring to something like a kenne bell supercharger. Not quite as much torque as our roots blower, but it's more efficient, and will produce greater power up top. Not to be confused with a centrifigul blower though, the boost will be linear like our roots blower.

the big issue with it, is that it's going to be a $2000~ upgrade, and right now everyone is spending most of their money paying off the new cars. i would say in about 1.5-2 years it will get alot more interest

Really? That sucks. But how many people actually race NHRA and IDRC circuits religiously with these vehicles? I know a few autocross. I guess there's a downfall to everything.
EDIT: Aren't Compound Forced Induction Setups illegal too?! I guess we'll be in the same boat.

Well on our car we're hoping for 400+ to the wheel, but we'll be happy with 350-360hp. Eventually we'll work up to the 400 mark if we don't get it the first time. We're planning head work and custom camshaft profiles. The efficiency of the twin screw is great and with stock internals, stock heads, 300hp is realistic. We're going to hit the books heavy starting tonight and put together a realistic performance projection. I'll post as soon as we get it figured out. Like I said our goal is 400hp to the wheel, no nitrous, just blower and engine.

The kit would be $2000-3000 more than likely. Tuning right now, is going to be handled by a MAFT/injector controller setup and methanol injection is staying on the car so we'll be using that also. If something comes out that gives us full access to the stock PCM then we're going to switch over to that. No offense, but sometimes you if wait around for someone else to solve an issue you get left behind. The J-body guys are still waiting for software. There's stuff out there on the market already that you can use without cracking the PCM. It sucks, but it's part of the game I guess. We're also looking into a custom manifold/intercooler setup.
