Vortech S-trim supercharger 10lbs of boost.
30lb injectors.. modified gt-40 heads.
Just put new head gaskets Fel-pro 1133's mls.
Runs fine, needs a new tune, running on a diablo chip....timing is a bit off..but still runs.
Problem is =
Even if the motor is cold......if i get into any boost at all or even under a load....or even without getting into the boost. It will blow water through the radiator cap and fill the overflow making a big mess etc....etc... and then it starts to overheat. Checked the oil...no water...havnt even gotten into it hard at all and it does it. Also.........took the thermostat out thinking it froze up. Same issue..........still blows through the cap etc... using a 16lb cap...and yes...new...bought two just in case....also....yes i even put a 20lb cap on there to see,,,, and still.....blows water through the cap overheats..etc...
Any ideas????? I bought this car a while back as is and went through all the top end after blowing the first set of gaskets which were stock replacement gaskets "shakes head"......
Also.......im pretty sure the waterpump pulley is aftermarket underdrive... stock belt rubbed on its self around the tensioner and the pulley on the waterpump...bought a shorter belt..worked out well.........is it possible that with the underdrive pulley its pushing too much water? Does it need a bigger radiator? does any of this make sense??
Please help, im at a loss.........
