Exhaust Temp

[nissan200sx.dk]

Hi all.

I need answer for some questions about exhaust temps.

On cruise what temp is normal, and what is considered high?

On WOT what temp is normal, and what is considered high?

And last, what is MAX temp before engine goes boom. (forged rb30, std valves in head)

Thanks

4-500 while cruising

700-850 under power

900 is getting critical...try to keep it under that

also depends on the season and the day [and your boost or engine stress levels]

hot summer

600

700-850

900 but you will see this just cruising for a couple hundred km at +40'C days and that is with a good radiator [mine is an alloy apexi 4 core item] with the a/c going.

On really hot days I have to slow down to 90km/h, if I sit on 110-120km/h my oil temp - and I have a cooler - and exhaust temp increase to threshold levels.

850 is about the most I have seen, even in a long race. we run it pretty rich though

Also running very low timing on WOT can increase exhaust temperatures
