Second is the steel GT4 a Twin Scroll Turbo???
Third I have heard a lot about variable vane turbos lately, especially for diesels.
Have driven a few 105/115 brake 2L diesel VW's with this technology the lag is non existent, alright at the top end boost drops off a bit (possible undersized turbo). The engine is 2L turbo, full boost at 1500rpm!!.
. full boost is i some 25psi 1.75 bar approx (or more in some cases).This technology if applied to petrol cars would be just a massive jump in performance.
I understand the the high pressures would be an issue in petrol cars but the lag 1500rpm full boost. Imagine getting full stock boost in the 2 at 2000rpm!!! Is there a
(VNT Garrett) (or other) turbo available for petrol engines??Anyone here, agents, dealers, distributers, working with turbos, hear of this technology being applied to petrol turbos?
Maybe this technology being applied to new products in a few years??
I presonally would wait a few years and pay twice the price of current new turbos to get a turbo woth this technology.
