I posted this in another forum, but I want to know has anyone ever thought of Compound Forced Ind.? For the ones who dont know it is were you use a Roots blower and a turbo in stages. I just want to hear opinions. Years ago it came out on a diesel engine and worked great, no lag time and the torque of a turbo, then they do it on a Toyota MR2 and works again, hmmmmm, just make s me think, and I want to hear what others think also! Thanks
seems like it would work well, since the added exhaust volume from the blower would really help the turbo spool as well. Only issue I see: cost - there are people running 10's and 9's on at least semi streetable GN motors without a blower, and a blower for these motors would have to be cu$tom made. Probably not worth the time/money investment...

Not an expert, but if you were to have a combo forced system, couldn't you use the factory roots-type supercharger from a newer GS or GTP? Possibly with a air-liquid intercooler as well.
Always good to dream of new combinations few have tried before
FWIW, lots of tractor pull motors are series & series-paralell turbo (2 turbo's feeding 2 turbo's) apps. they use the primary turbo's to spool up the secondary ones & the secondary ones for making the big numbers.
I think its a great idea, I would love to see one that works. there was a guy about 15 years ago that made a setup that had twin turbo's blowing throgh a blower in a little Pro Street Nova.
