I'll try to keep this simple...
bitch is getting too hot. gauge is just starting to creep when I notice. probably 213-218° so not too hot. but still hotter than I want.
did it on the B20 and now the D16Y8.
2-3 OEM lookin thermostats. at least 2 of them with hole 6-8mm in size. temp is 72°/178°
both my fans work great. and as they should. stopped and stop/go it is fine.
she heats up tough on the freeway at speed. 70+.... and if you tip in/wot...well then she gets pissy and you can just watch the temp climb. (didn't note this on the B20. didn't do many pulls on that busted motor)
its got mostly water. about quart of 100%. and water wetter per instructions.
radiator is half shrouded. half open. with 2 12" fans.
downpipe and dump are header wrapped. manifold has shield. dump tube goes to ground under tranny.
I have tried to direct air to the radiator as best as possible. got foam insulation from core support to radiator to tighten air leaks.
it has oem'ish china looking replacement radiator. maybe 5years old? 30k miles? no obvouis signs of damage etc.
that's all I can think of right now. this has been an on going thing. ambient temp gets like mid 70's she starts to act up. but didn't notice temps above 200ish on the dyno. or it creeping up.
