Turbo manifold design

[RICE RACING]

The long to short runner thing is a classic and it WILL do your head in LOL.

One of the classic examples of a horse cock manifold is to look up the old TWINS TURBO converted Red Time Attack FD3S, running massive horse cock exhaust manifold with BW turbo and PENI GROW on steroids 5" dump pipe! and 4" exhaust !!!! you can actually see video of it doing ~480rwhp on the interwebz on a dynapack machine when set to ~20psi boost pressure. The amount of fab work and shit on that engine bay set up is homo in the extreme for very little return in performance.

You can see at least two other examples of short manifold cars running same or less boost and dyno'd on the exact same dyno types returning more power and with the same power band if not actually better. All around 500rwhubhp @ 1.3 bar boost pressure.
