I did a run just to see how bad my car was doing with the wrong converter/turbo blowing oil. Becasue of these, I can only powerbrake up to ~1600-1800rpms and can't even get a # of boost. I ran a 15.1 @ 100mph. The time is low, but the mph looks very promising. I have seen that most cars running in the 100mph zone run in the 13s. Is that correct? I am just trying to figure out how much of an improvement a stock or 2800 stall converter will make in the 1/4.
