can you stuff a 3.5" pipe down there without beating the crap out of it?

qm, you may need a ram air hood scoop to feed that thing.

Wouldn't you get less boost at low RPMs ?

But more HP at high ?

Yes, but what does that mean? I get minimal boost below 2000 rpm with the GM-4 sprung shut.

That's why I'm installing headstuds and dropping CR to ~19:1. It's just part of the package. I also found a new $150 PS IC 3 1/2" inlet-outlet, just huge something like 28" x 32" x 3".

I plan on working it hard. Pulling trailers is only 50% of the workload. I'd like to think traffic won't seem so fast anymore as I might be moving at an increased volocity.
