Hey guys, I am sure this has been asked or talk about many times but I cant find a real good answer on this... Simply how much boost will a 03/04 cobra hold on a single turbo set up? I am sure depends on a few things like tune, fuel, so on. MY car has factory crank and rods with manley pistons and arp 2000 rod bolts and arp head bolts. Any certain boost I should not go pass on 93 octane and on e85? fuel system is return L2 fore with dual 465 pumps and ID 1000s. Just wondering what the window is to be fairly safe? thanks for any input.
