Seen this over on the hot rod boat site, then read the arti in powerboat mag.. What a bad *** set up... It is twin turbo'd and blown. Will make over 1000hp when set up right... This is what I h=found looking on the web, but the artile in PB is better

Yes i just checked it out in the new diesel magazine that came out, it has twins and a supercharger. It is BAD A**!
In the mag they said they cant wait to see it in a hot rod, anyone up for a challenge!?

 

Hmm, that forum is calling it a "sequential" supercharger-turbocharger setup. I Don't see anything sequential at all about it. The turbos dump into the intake manifolds upper plenum beneath the supercharger before the A/W inter-cooler.
That's NOT sequential.

Still a bad *** combo, they must have a vacuum/boost operated differential pressure switch/solenoid that operates a valve where the turbo charge piping meets the upper intake plenum. Otherwise, at low RPM when the turbos aren't producing boost, that supercharger would just be back feeding into the turbo's charge piping, not building boost in the manifold.
