Atomic ran something like 8 lbs on his high CR 408 with no problems as far as I know. TVS blower.

 

CR isnt the problem.. Fuel and timing play the larger role.. Just like on a 8:1 CR.. too much timing and its gonna pop..

 

its my dd in the summer if its not raining but i just wanna shut everyone around here down. im 600+ prob a 80mm turbonetics.

 

What kinda power are you looking for?

 

close to 600 wheel horse. i have a brand new built 4l60e: that prob wont last long..
i know im gunna pick up injectors bigger than 60#s the aeromotive 340 most likely.
prob a lsxrt intake prob yank it out and do forged pistons and robs and hell fire rings:
ill prob have pat g speg a boost cam. a damn decent one too. i have a 228r new in box i might see if i can wheel and deal with for that.
then theres just the turbo kit and the tuning..

 

a fully built 60e SHOULD last you for awhile if you arent "drag racing" everyday while driving it. You also should be good on stock internals if you don't go too crazy on the power. These engines have proven with good tuning to hold up to 600+ without problem.
