Texas...I know it gets hot where you are (100 plus)...but even in 93 degrees F with high humidity, 87 is fine...even under severe loading conditions with marginal cooling. I really took great care in designing the hemi combustion chamber, compression ratio, cooling fins, etc to balance power and reliability for long life. We have had zero detonation problems so far. Remember, higher quality fuels are not available everywhere...and I wanted to make sure that our engine will run well with no problems on 87.
93 octance was tested some time ago and we lost 100 rpm off the top.
Todd,
That's an interesting approach. I also liked your explanation of the metals used. Very high quality materials.
Thanks
Jim
