Re: Fixing SR-18
 

Man, that is depressing. I see the Sumoco guys standing around a lot. Not selling fuel. I wonder why? LOL

Re: Fixing SR-18
 

Comp is a sportsman class. We should be able to run what we want. Sunoco or the option to run vp. Hope they let us run vp next season

Re: Fixing SR-18
 

What is the benefit of running a fuel that is getting "flat"?

Re: Fixing SR-18
 

Why should Comp be forced to use a certain fuel? Since they are sportsman cars they should be allowed any fuel on the accepted fuel list just like Stock and S/S. Let Pro Stock and Pro Stock Bike keep being forced to use Sunoco SR-18.

Re: Fixing SR-18
 

Sunoco spent a lot of money to ensure that they were the official fuel of NHRA. And they want to recoup as much of that money as possible.
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.

Re: Fixing SR-18
 

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.

Re: Fixing SR-18
 

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.
