What amount of boost are you running on your LT4?
- What are you running for boost on your Lt4 ?
- Did you notice issues if going over 10 psi (e.g stock boost)
- Have you made any cooling or other mods to support the higher boost ?
- What is the highest safe limit on these motors ?

I’m running 18.2psi but chasing spark issues since I got control of the throttle body down low. I’m going to gap the plugs tighter than a crabs *** and go from there...

I'm at about 17 psi on the stock blower and yes it gets very hot. I'm mostly going to be drag racing it from now on. Only have 1 track day scheduled for this year and I'm able to cool it at the drag strip. If I were going to continue road course I would do something else about it. I have installed the DeWitt's Z06 " cooling kit " it has helped, but doesn't completely cure the problem.
