Thread: Stupid Question but ill ask any way

I saw a dyno test of these somewhere... The turbo is already out of breath before 5k rpm. It's a fast-response, daily-driver tiny turbo. A bigger turbo, a couple flow mods, and a tune would net 400+ easy.

Here it is.

But why are we back to the late 80's TPI 4500 RPM days? ****'s dumb if you ask me. LNF was fine, why change it? It can't possibly be cost effective to develop 4 new ecotec variants instead of modifying the current ones to meet CAFE standards... Oh, GM.
