Q: induction style dual turbo setup?

hope this is advanced enough. Jordan, or anyone?

i'd seen severeal of these run on 1000+ RWHP cummins diesels and was just curious as to why i've never seen anyone that has done this w/ a gasoline engine. basically what were talking about is say a t-66 or equivelent, thats large on the exhaust side A/R for free flow, that the exhaust side also feeds a t-88 (smaller exhaust a/r) or larger turbo. this in turn blows it's pressurized air back into the inlet side of the smaller turbo, which feeds the intake. kinda like pressurizing a turbo, so it compresses allready pressurized air. the only tricky part would be matching the intake flow requirements of the small turbo w/ the flow charachteristics of the larger, so it never runs out of compressed air.

i feel this would also fairly effectively dissipate more heat from the intake charge. but would the benifits of this system be worth the effort? perhaps this is why?

yes i realize that most setups work with one turbo and work well, but i want to at least know why somone has not attempted this. too complex? too much air? other downsides? any thoughts?

here's some pics if this helps,

very interesting man, dunno why.. be cool to try it tho :)

ive seen several twin turbo gasoline setups making over 1,000hp, but that was with both turbos pressurizing the intake.
i havent seen a setup with 2 turbos pressurizing one another (or however said configuration was configured) and im not sure of the benefits.
the reason there isnt many people running that setup, im sure, is that the current turbo offerings and configurations are capable of making more than enough power, and are familliar which aids in tuning. but, hey, im all for new technology, provided it works better!
