Oh, you think so little of me that I'd associate with ricers? :p
One of these guys is running a v6 turbo T-bird in the 11's(daily driven) and the other was in the middle of fabing a twin turbo setup for some really sedate looking import 4 door sedan, there version of a sleeper I think.
Anyway, I made it clear from the start it was not really a lack of full boost, just how long it took to get there. They said the impeller was heavy and an ineffecient design, that for a given exhaust gas flow it was not turning up to speed as fast or makeing as much boost for a given impeller speed as a newer one. They named a few that are common and might bolt up.
It'd be a little nieve to think turbo technology had stood still all this time anyway. One of them was also looking through some part number books and said the SDL had a newer version of the Garret I think it was...
I have always thought a quicker spooling turbo would be a fine thing on thise motors. I want full boost at no higher than 1200rpm. Dammit.
