On Monday, VP Racing Fuels introduced two brand new unleaded, nonoxygenated race fuel blends — C20 and VP Unleaded Extreme — to the market, with each delivering rather significant performance gains versus competing unleaded fuels. As VP’s Regional Manager-Midwest explains, “as with any VP fuel, C20 is best in class, but you could say VP Unleaded Extreme is in a class by itself.”
“C20 is an improvement on VP’s popular C10 race fuel with increased power and torque, along with a significantly higher octane rating of 103 (R+M/2) for better detonation protection,” continues Rueckert. “It can handle 30 lbs. of boost and compression ratios up to 12:1, plus its RVP is higher for better vaporization in naturally aspirated engines.”
The new C20, with its higher octane rating, makes it a great fuel for use with intercooled, forced induction engine combinations common in drag racing. VP worked with John Wiker at Johnny Lightning Performance during the development of the new blend, utilzing a supercharged Ford pickup truck.
“We had been running Shell URT and making 700 horsepower to the wheels with 24 lbs. of boost with a 2.8 Kenne Bell Supercharger,” said Wiker. “When we switched to VP’s C20, it allowed us to advance our timing two degrees and picked up 15 horsepower. C20 also reduced the black smoke we’d been emitting before. With URT our best run was 9.89, but after making some modifications and switching to C20, we set a personal record in testing with a 9.59 at 143 mph. This achievement was due, in large part, to C20.”
“With VP Unleaded Extreme, our Mad Scientist has created the ‘be all, end all’ of unleaded, non-oxygenated racing fuels,” Rueckert said. “VP Unleaded Extreme can be used with lots of boost or naturally aspirated, or as a ‘concentrate’ to mix with other unleaded fuels to increase the performance and octane,” Rueckert continued.
Unleaded Extreme carries a Motor Octane (MON) rating of 110, which according to VP, is five points higher than any other unleaded fuel, making for impressive detonation protection.
VP points out in the release that C20 and Unleaded Extreme are both great choices for drag racers wishing to use unleaded fuels or those competing in eliminators that require nonoxygenated fuel.
VP Racing Fuels will be on hand at the upcoming PRI Show in Indianapolis (Booth No. 4201) to answer any and all questions regarding these two new unleaded fuels. For more information on VP, visit them on the web at vpracingfuels.com.
