I guess i'm at a loss here. i helped my friend put a 4-71 blower on his
'vette over the winter and we basically just replaced the intake manifold
with a plate that sat in there that the blower was bolted down onto. It had
all the ports in it like an intake does. Maybe I'm not understanding what
you're trying to say.

So, if the length of the outlet is perportional to the engine size, for you
to be able to use on on a V6, wouldn't you have to then find one that came
off of a V6? If you could find one of those, making the mount to secure it
to the top of the engine would he relatively easy i suppose.

wouldn't either intake manifold be designed to the air to flow in? I've
seen people use the "ram" syle of intake with a roots style supercharger,
but with a turbo you could use any type of intake manifold you wanted, you
just need to make sure that you've got a good seal between the intake tube
and the TB/carb.

What would that accomplish? that's basically the same idea as using an
aluminum plate to cover the belly pan. I was talking about doing something
similar to the M1 2bbl for the V6.
