Stock internals on e85 how many #'s of boost have you safely run

[Offaxis]

Anyone running 12#'s or more on there stock engine ?

Personally 10-12 is the max I usually go. Im sure there are others that have pushed it more.

I stopped at 10.1psi. Made 713 and I dont want to push it any farther until I build the motor.

Wastegated at 11.6psi with a procharger on e85. Made 702whp 657wtq on 10.1psi. Probably about 740whp on 11.6...i also have an engine diaper installed for when it goes

I made probably 25-30 passes on 13lbs of boost with just OPG's installed. Never beat on it on the street. Just ordered my 11-1 Aluminator shortblock. Should be done in a month or so and I will turn up the boost a bit more to 18lbs or so and see what shakes loose.

8.5 and AED tune is all you will need

"Safe" trap speeds on the stock internals are more interesting to me than psi.
