Twin Charged RX-7 with a Toyota 1JZ VVTi swap is also rocking a Borg Warner turbo and a M90 supercharger. (http://thegarage.jalopnik.com/check-out-this-twincharged-engine-swapped-mazda-rx-7-1787080619)

The low-mounted Eaton M90 supercharger boosts the engine at all times, then his Borg Warner S366 turbo spools up and adds power on top of that higher in the rev range, he doesn’t seem particularly troubled by his setup.

that's pretty cool. I think he said 20 lbs boost. you think the m90 gets in the way of that big ol turbo being compound boost? some weird cavitation thing. I only say that cause our M90 is good for what 15-18ish lbs. I think everyone has doodled a compound and/or twin set up and then crumpled it up and said naah.. hats off to him for doing something different. if you're ditching the rotary rev the SC whine is a great substitute sound wouldve been nice to see a boost gauge blip.
