I have a single turbo cobra, running 19 psi on 94 plus water/meth, with an 03 mach 1 intake. The car is essentially a dd street car, makes good power I'm just curious if switching to a sullivan lower with an hpp upper would be worth anything or a waste of time. I might be going with a larger intercooler and larger cold side this winter so I was just curious if this would be worth doing? Car has a built motor, right now I spin it to 7k it does pretty well.
