These are the specs I have , I've always had nitrous cars and one single supercharged car. So this is very new too me . But I'm the kind of person that if I'm gonna do it, I'm gonna do it big and go overkill on everything . The engine, fuel system, rear etc will all be up too the task of supporting double my goal, and according to this those turbos in a pair should get me up around 1400 spinning the hell out of em
