glad to see this thread is still going but i got a couple un answerd questions,
1. if the turbo's feed the super charger wouldn't the super charger cause a restriction at higher RPM?
2. also isn't it possible that you break the super charger by forcing air into it?

its not so much as cause a restriction as cause heat. compound boosting will generate LOTS of heat in the intake. this is why i recon, and ithis has been used in motorsoprt, that bypassing the SC at higher RPM is a better solution. that why you get the supper fast spool of the compound system without the higher temps....
i have heard of the heat causing damage to the roators and housings of SC on twin Charged MINI's....
ZZp makes this kit for the cobalt ss. it just helps boost the car while the turbo is lagging then helps produce more when they are both spooled. Really only a good idea if you want to run like 30psi and get there quick. requires internal work though to accomplish that kinda boost. There is alot of work in doing it and many more variables that can go wrong. Good idea though.

Seems like it would have some insanley high intake temps
at 44 psi (the turbo's were putting out like 24psi of that, im not sure how that works.) with the stock s/c and compleatly stock motor and even exhaust manifolds the hellion car made 1188 REAR WHEEL HP and something like 1108 ft lbs at a real low rpm. this setup is honestly insane, and capible of ALOT of power. thats with a set of twin 66's on a little 4.6
imagine something like this on a tvs'd lsx 427 with twin 88's.
Check out www.zzperformance.com for more info. Matt at Stattama is I believe the designer of ZZP's twincharge kits for the L67 and LSJ. They make good power but no more than a good turbo setup. If you want to see some people running them go to clubgp.com and check out the turbo forum.
They basically use the supercharger to spool a larger turbo than can be used without the S/C in the loop.
This is just my understanding, and the specifics may be different. I dont know if Stattama makes kits for other cars than L67/36/LSJ though.
ZZP/Stattama make great products. My bolt on 9.5:1 Grand Prix with a Very mild cam (200/212 .504/.520 @1.6 115LSA) and a 1.9x 60' ran 12.68 @109 almost full weight.
That is true, but they use the blower because it is a 2-stroke motor with reed valves. It would be pretty much impossible to get an intake charge past those reeds without the roots. The turbos on them is just a huge bonus.
Wrong. 2 stroke diesels have intake ports at the bottom of each cylinder liner that are uncovered when the piston reaches the bottom of its stroke. the supercharger only supplies air to idle on. when theres enough boost from the turbo the supercharger is bypassed.
