im working on a friends car which is a 5.0 .30 over(306) with trick flow internals,he's currently running 10.5:1 comp. with a paxton charger putting out 8lbs of boost he now wants to add an intercooler and water/methanol injection so my question is without studding the heads (aluminum trick flows) how much trouble are we gonna get into.is adding these items going to drastically increase combustion preassure to the point of ripping out head bolts?
