Fuel Question

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?
