Ball bearing turbos are definitely not out of date and its a good thing cause they aint got as much friction. But I really can't knock the t28 too much. Alright its small but the Garrett bb t28 spools up pretty quick, but yea, the output may not be as high. Hey, I mean c'mon, there are positives and negatives to everything. Oh yea and autocross and drag are for 2 different types of drivers so even trying to compare them is retarded.
