Paul;

The EGT depends on your operating conditions, of course; but are not too high. I found on the dyno = that at max power mixture (rich of peak) and WOT at 5300 the temps were right = about 1550F.

I also found that the coolant = flow rate is 35-40% higher without a thermostat than with. So it is no = surprise that your running cooler.
