Fuel Question

gilmoujr · 09-10-2002, 06:52 PM

Has anyone ever run high octane fuel (like 110+) in their late model GT (4.6). I was wondering if it will better my track times or cause more damage than it is worth. Will it cause damage? What is the highest I should run if it is okay to run race fuel? Las time at the track I ran a 13.760 and was wondering how much further I can go... without blowing up!

Don't think it will damage anything. But, it probably won't help your track times either. Unless you are knocking, using high octane fuel usually won't help you out.

Hey,

Hammer did a kick*ss review of fuel and what octane ratings do and all that stuff (that man knows it all...). I think it was posted in windsor power not to long ago. Check back a couple of weeks and look for a fuel thread. It really helped my understanding of fuel.

Thanks. I have only stuck to Modular madness and Street Racers (for the stories). I guess there is valuable info in other forums for me, too. I will check.

Thanks Titan.

Depends on what fuel it is. Most racing fuel has a higher octane rating. Higher octane rating=more hp. more hp=better times. I use VP racing fuels in mine..and they are the best out there hands down.

Not always. The higher the octane, the more compression it can withstand before it combusts. So yes, racing fuel may give you more hp by letting the pistons reach TDC, but if 87 octane fuel will let your pistons do that, then why use a higher octane?

I've never seen a car that didn't respond well to racing gas so it must be doing something right

Higher octane burns slower thn a lower octane..depending on you set up you may loose HP with higer octane...Higher octane = mor HP with more advance timing...

Maybe a little clarification....Higher octane burns with a colder flame =slower burn....you need advance with higer octane to get you HP
