Intake?? Whatever the air temp is.
Exhaust temps can be as high as 1200 Deg F. But if you push them that high for too long... you will melt the piston.
I don't think your LRV shows either of those temps on the display.
Normal running temp is around 190~200 Deg F. (in the water jacket)
If I'm reading your question wrong... just let me know... and I'll try to get you the right answer. :cheers:
