I don't even want to know what temps 400hp would result in, haha

I could probably do a single hot lap at 14-15psi; but that's not what I was going for. This next year at the NASA and RL events; I'll be doing more of the single time attack laps...so boost/power will likely go up.
Interesting. I'm pushing ~ 425/475 RWHP/TQ to the wheels (17-18psi) with the Procede/PWM Meth system and did a hard 6 lap set around Big Willow after a few warm up laps. Oil temp gauge hit 250 and stayed right there through all 6 laps (so car was on the track for ~ 20 min straight, being pushed hard for about 10 min). The brakes quit on me otherwise I could have kept going...not sure for how long though but it seemed like the engine wasn't getting any hotter. I have zero cooling mods except meth. Willow is at 2,700 ft elevation and was fairly cool that day, so perhaps that also helped keep oil temps cool.

MFlowT5 tracks his car quite a bit at over 400+ wheel HP and meth and I don't remember him experiencing cooling issues. Maybe he can chime in.
