Thread: Header Temperatures

Tweet

Check the timing. Retarded spark will cause hot headers. 2000 rpm under no load shouldn't make that much heat.

the mechanical timing was set at 8 BTDC. After letting the ECM take control, the timing goes to 23 at idle and 32 at 2000rpm. Right where it should be so the timing is fine.

The glowing headers are my concern. Does 375F sound too hot? Any oil drip onto those headers will catch fire which is bad.

Yes there will be fire if you spill oil on headers
I think you will know if you get a over heating problem and by plug color.
I used to have a chart,dull red 500approx, cherry red 6 or 700,orange is 900 approx and white hot is approx 11 to 1200 degrees. I am sure those temps are far from correct ,but you get the idea.
