Ok i really want a Kb roots blower so i think that i might sacrafice my cobra for a new gt and put their top psi intercooled blower onto it instead of keeping the cobra and doing the D1SC on it and tunnin about 15 psi. i think that i will have moe fun with the roots system. well i need input on what to do. i have seen graphs of gt's that have like 400+hp with the roots so i figure that this will be enough. well thanks
