Nooby Q, very noob

What is the effect of moving the turbo further from the head? Does it increase lag time?

[BLK92_D16]

Like, say a rear-mounted turbo? or what? Just mostly for space... And yes, a log manifold would have less of a "lag" effect because of less travel. So longer the piping, the more "lag" time.

makes perfect sense

i think your both wrong...lol

BLK92 D16, lol explain how an equal length manifold which has more internal space than any log manifold usually allows better response and less lag..... your statement is incorrect.

[rattmann316]

length of manifold piping has nothing/very little to do with spool time. most spool issues can be addressed with the turbo internals.

This is what I was thinking. Figured the pressure inside the manifold was fairly similar once in was completely pressurized no matter how much volume was there. There also would be less bends/bending than in say a big ramhorn or something of the like. Also a little harder for CHP to figure out in a routine stop. Wondering how much of a turbo may be able to be hidden in the rear of the engine bay.

Correct me if im wrong, but isnt a turbo manifold in some relation to an N/A header in the fact that runner length will have an effect on you power band.

i.e. a log manifold will cause you to lose top end power but will have a little better spool time, but having a tubular top mount or ram horn style manifold will actually hurt spool time a little but it will show significant gains top end compaired to a log style manifold?

i just remember hearing that somewhere... i could be totally off though.

a lot if you had a k swap...

Was thinkin' the same thing, but I don't want a K. Or is it that I can't afford one right now?

Well, another problem with getting the turbo further away is the charge piping. You have the opportunity to lose alot more pressure when you start adding charge piping length.

I was gonna try to keep a SMIC somewhere in there to keep that issue at bay. Looking that might be hard, but to route it up front would only be 18" more max. I would think that turbo selection can help this.

That's exactly what this site and turbod16 has taught me over this last year! so that's what I'm stick'n too!
