This has been adddressed;

No it won't.

I take it you have not looked at any dynos of rear mounted turbos.

LS1's & LT1's are spooling up full T4s by 2500rpm using 2.5 or 3" piping.

The air is already flowing through the piping. It's not like the turbo (or turbos) has to pressurize completely empty piping.

There is less pressure drop (i.e. causes "lag") over 10-15' of piping then across ANY intercooler.


I suggest you check out some information on a properly mounted rear turbo. It performs nothing like I imagined it could. There is zero lag & more temp drop then a decent intercooler.
