<<  Thanks Lynn E. Hanover. That's right where I'm at. I run 1580-1620
depending.

 You are welcome. Next year the Sports Care Club of America is going to let
us run
two 38MM chokes instead of two 36MM chokes, and is adding 100 pounds to the
Toyotas to bring them up to 2080# same as the Mazdas. If we can make that
change and come up with a dog ring gearbox, we could be very competitive.

I saw a member lost some insulator off of a plug and was thinking detonation.
I would think about going to a much cooler plug range if that is not now the
case.
Aircraft engines are at high RPM high load most of the time. The idle and
slow speed low load performance of a hot street plug are of no value at all.
But the high temps can crack off a piece of insulator once in a while. Very
bad business if it gets loose in there and cracks an apex seal or scores a
housing. I have never in 30 years lost a racing (cold heat range) plug. But I
have lost many street plugs just in the tow vehicles.

Take a look at the car on this web site:
