So I am planning on getting a large Whipple by the end of summer. This is for my Cobra. I want the car to have 625-650 rwhp but safely and without going in the engine. So I am gonna start doing some reserch on the best displacment twin for my power goals. I am also gonna do a meth injection but want the 625+ to be without it. How much fuel system do I need? I want to keep the stock tank but can I just get dual super car or Focus pumps? Also what size injecors should I get? Do I need larger rails or lines or for 650 is the stock lines and rails enough?
