desolate · 05-12-2009

I have my regular arps torqued to 110ft lbs with an autozone composite hg (felpro) w/copperspray.

Doing 33psi spike(16g) and 35psi(scm61) with no hint of coolant pushing. I know that's higher than what arp rates them for but it has worked great for me. This is with molylube as well. I used to stop at 100ft lbs but I always had leaking issues, the day I decided to go 110ft lbs was the day my high boost coolant push issues were gone.

And then the day I start to push coolant on this setup is when I'll go with L19s.
