roots blower on EFI small-block
I've been thinking about doing this. I have never seen this done before. If anybody has seen it, please give me the website URL or whatever. The concept is simple. Use a roots type blower on a small-block chevy but keep the factory EFI system. It's what the C5 guys can do with that Magnacharger. The thing there is that company has done the R&D so there's an intake already setup for the injectors and it accepts a throttle body, etc.
What I have been imagining is to take a blower setup from, say Weind, and modify the intake below the blower to accept fuel injectors (easier said than done) and then fabricate something on top so you can put a throttle body on the top. You could do that a number of ways.
Obviously, it would stick thru the hood, so I'd want a "donor" hood. But, the visual impact would be awesome of course, and by having the EFI programmed for the blower, the drivability should be excellent as well compared to carbureted blower app's.

my old room mate had one of the B&M Supervettes back in 1989
it was built upon a 1988 4+3 vert, triple black and utilized a B&M Roots style blower w/ efi on top - it was a 4 injector setup and the car on gatorbacks ran 12.8, maybe 12.7...
It was a sweet ride - kinda primative in the tuning but upper 12's in that day was dang good

Back when I worked for Whipple they did an intake manifold and throttle body adapter to bolt a twin screw supercharger right on to an L98 but they never completed CARB testing so they never put them on the market..too bad the kit fit really nice under the hood and the screw blower is way way more efficient than an old school roots.
