 Uughhh... I really hope you're wrong about this. Mine cools great on the
ground. Define "full throttle" in terms of length of time? I've gone to
full
throttle for about 8 seconds with 6 psi boost, just to test it, however I
normally limit it to 0psi boost or 30" MAP. At this I've done static
run-ups
for up to a minute. I've taxied around for 45 minutes at various power
settings and never seen more than 90C on the coolant and 85C on the oil.
I hope it's not a wind bag in the air.

Hmmm......   You don't think 8 seconds counts as cooling do you?  : )
By cooling, I mean that the temperature has stabalized.
Lots of dragsters have no cooling system at all and "cool" OK for 5 - 10
seconds.
