The profit margin on the higher octane race fuels is larger than the margin on 110. And Comp racers use the higher octane fuels. So if any class that uses higher octane fuels is forced to use only Sunoco, they stand to make more of their investment back. It's the same strategy that VP used.

Unless you consider Non-Supercharged and Non-Turbocharged Pro Mods low horsepower race cars, then your statement is incorrect.

Non-Supercharged and Non-Turbocharged Pro Mods are allowed to run VP fuel.

My statement doesn't mention horsepower at all.

Upfront disclaimer: Your results may vary.

That being said, my 16:1+ comp ratio engine dynoed downto the HP the same (we did back to back tests) and ET's exactly the same on C16 and SR18. The fuel has always checked legal and was right in the middle of the range. In addition, SR18 is cheaper than C16. I'm not disputing what has been said on the internet, just stating my personal experience.
