yet another problem today i removed my heatsheild and found a crack on the manifold about an inch and a half long how much powerloss is this costing me and could this be the reason why i cant set my boost at 15 psi with my mbc it only goes up to 9 psi??? and also can i use jb weld to fix this problem till i get a new one????thanks

did you mean exhaust manifold, because as far as i know the intake manifold doesnt have a heat shield. And i dont think that JB weld will hold up with the amount of heat that it will be dealing with. I dont know exactly what they are rated for though

actually i just used that stuff on my radiator because i had a crack in it and man that stuff is amazing. But you have to be quick with it. You sit there and knead it in your hands and it will start to get pretty hot. Then apply it fast because it will harden and if it does then its useless. But that stuff worked great on the top of my radiator, not sure how it will work with metal. But i guess theoretically it should

new exhaust manifolds arne't terribly expensive and if your gonna spend the money to replace it you may as well go ahead and upgrade to some headers... quicker spool times
