Seems as if you need an EGT (exhaust gas temp) gauge for that application. Here is what I dug up.
"EGT Gauge
The exhaust gas temperature (EGT) gauge shows how hot the exhaust gas is. The way the supercharger over runs the stock fuel system these temps get super hot which I am convinced will shorten engine life. If you have a supercharger I highly recommend installing an EGT gauge so you can monitor the exhaust temp. You can check out my fuel delivery page to see why I think this is so important. I used a Westach dual EGT gauge that has two needles in one gauge so I could monitor the EGT in each cylinder bank. They are high quality and so much cheaper then Auto Meter. It is important how to read an EGT gauge. If you see the temps going up as load increases and then suddenly see the temps drop off, be careful. That is a sign of detonation and a tremendous amount of heat is being absorbed internally and could lead to an engine failure. Look out for that. In my dyno testing max power was between 1400-1450 F. Over 1450 the power would drop off indicating a loss of power from to lean of a mixture. {"
