car went 14.0 @ 99.79 on that pass very low 13's on a 6psi launch with a full out run on 6psi,car has made a bunch of low boost runs just to break in the motor, nothing to serious yet,weve loged 343 miles on it now besdies the dyno trips and few highway runs island would have been the first full out high boost run.

which after the hose incident for the second time wont happen until i can find out why im pressurizing the cooling system,tom im going to install a presure gauge taped into on of the coolant ports on the cyl head or block and take it out for a high boost run and see what it does. im really thinking that either i am lifting the heads,or blowing compression right past the fire ring on the head gasket.only other thing it could be would be a misaligned intake gasketbut then the car would run liek **** all the time

lol if i blow the lt1 i can use that turbo on the ls1 or the 4.3 vortec motor, though my t74 i have for the 3.1 is larger then the gt45
