All that on the stock internals? I'd be careful man. 465-480 to the rear wheels is really pushing it. Thats right around where i want to be with my stock internal cobra with the same setup pretty much but instead of the aftercooler im going to get a icevex intercooler for like $350. You have a sweet car though. Do you have dyno sheet pics and do you know what your a/f is during your dyno runs? Would really like to see them.
Good luck with the sale
