Nissan 370Z Forum - View Single Post - Stillen S.C. Plenum charge assembly coolant leak during WOT on dyno

At idle, there was no white smoke at all. It makes me believe if there is a leak, it is small. The reason for the white smoke at the end of WOT is the blower is producing 6.5 lbs which was also pressuring the independent closed loop cooling system for the plenum through this leak. When the Z went into vacuum, the now pressurized plenum cooler then discharged coolant at about 6 or so psi. Hopefully I'm not screwed. Like I mentioned, car ran fine afterwards. Curious if anyone ran into a similar issue and could shine in whether or not I hydro phucked my engine.
