There is a thread somewhere talking that exact same thing... At what rwkw is too much for the street. If I remember right I think a few of the boys with 400-500+ rwkw were saying that about 350rwkw is the limit for the street, otherwise stuff like TRACTION become real issues. The boys driving autos with big power drive in manual mode to avoid kick down when accelerating, cause I can just imagine how exciting that would be when not expecting it.... Street driven also means 'in the wet' 700rwkw in the wet in any car is just stupid imo... I have trouble in my car in the wet and im no where near 300rwkw. I agree with Michael (ypurv4) set urself some mini goals along the way... say conversion, then 300rwkw, bottom end, 400rwkw, turbo etc.... Cheers Mike...
