om617 boost limit ? - Theturbodave - 05-16-2012
Whats the most any of you have seen or done. Mine must be a freak cause I run 30 to 35 psi at all my drift events compound turbo with NO intercooler ( I know WTH right, I can't figure out were to put it). It heat soaks after 3 to 4 back to back runs. You can tell it looses power when intake temps get up there. I had it overheat once at an event but that was cause i let someone else drift it and they did 5 back to back runs. We let it cool down refilled coolant and went back to running it. no problems since. I just wanted to know how much I can do before it explodes.

Supposedly you start bending rods around 2.5bar YMMV
Do you have a pyrometer setup? I'm curious what your EGTs are with the cut DV's
