I have process west setups on both my manual ute has 380 rwkw stage 2 cooler and my tornado has the full plenum kit it has been tuned for 412 rwkw . they never have issues with inlet temperature just with the radiator trying to keep the gearbox and motor cool. once you go skywards of 350 rwkw everything gets real hot real quick I had both utes running around powercruise last year and felt the inlet after every cruise around the track and cold to touch. I did not get one ping and the performance stayed the same all day. My cars were getting hammered I do drive them hard. You can only get about three laps before the auto goes into limp.
