VP Racing Fuels
It’s not just “race gas.” It’s performance
fuels of all types—racing gasoline, racing methanol, nitromethane, small engine
fuels, hobby fuels, storage fuels—essentially any application requiring custom
formulation for specific performance characteristics. And the pump gas you’ll
find at VP-branded stations? In keeping with VP's demanding standards, you can
be confident it ranks with the best on the market.

C9
C9 was introduced as a complement to VP’s popular
C10 as an economical alternative that offers more resistance to detonation and
substantial performance improvements over premium pump gas. In fact, tests in a
crate engine showed gains of 3-4 Hp and more torque than a competitor’s 110
leaded race gas! An ethanol-free, non-oxygenated unleaded fuel, C9 burns very
clean and won’t harm catalytic converters or oxygen sensors. Because it contains
no ethanol, C9 prevents all the problems associated with ethanol in pump gas and
does not require draining the fuel system while engines sit idle.
C12
The best all around racing fuel made. Recommended for
CRs below 15:1, satisfying the needs of 75% of today's race engines. One of the
winningest fuels in racing history, including NHRA, Modified Tour, GNN,
D.I.R.T., Indy Lights, AMA as well as other local and national championships
across the U.S. and around the world. Spec fuel for NMRA and NMCA.
C16
Used in turbocharged engines, blown engines and nitrous
applications with CRs up to 17:1. Recommended by the top nitrous oxide
companies. Spec Fuel for NHRA Comp Eliminator.
C85

Q16
Q16 will work well in any drag racing
application -- naturally aspirated, nitrous or blowers. Q16 is highly
oxygenated, requiring a 4-6% increase in fuel flow, which will make 3-5% more
power than competitive 116 octane fuels. Q16's oxygenation will significantly
expand the range of air/fuel ratio acceptability, so performance will be more
consistent and won't vary as dramatically with altitude or density changes. For
bracket racers, variations in ET from run to run will be substantially reduced.
This added fuel flow also effectively increases its octane by 6-8 numbers above
its standard ASTM octane rating.
Motorsport 100
Oxygenated with ethanol, this CARB-legal fuel is specifically engineered for
high-performance street cars including sport compacts, muscle cars, street rods
and more. It's environmentally friendly and street legal throughout the U.S. In
applications with anything from 4- to 12-cyclinders or engines equipped with a
turbocharger, supercharger or nitrous oxide system (NOS), VP100 will generate
optimum power and performance. In turbocharged or supercharged applications, it
allows an increase in boost without fear of detonation. NOS users can also
leverage their higher octane ratings to step up to a more powerful nitrous oxide
system. Dyno tests with a turbocharged application proved VP100 generates up to
14% more horsepower compared to premium grade 91 octane unleaded gasoline.
Designed for use in cast-iron head engines with CRs up to 13:1 and aluminum head
engines up to 14:1. Works well on the latest generation of
electronically-controlled turbo engines. Contains no metal compounds and won't
harm catalytic converters or oxygen sensors.
Late Model Plus
Recommended for use on 3/8 mile or greater dirt and asphalt circle tracks in
engines bigger than 400 CI with CRs up to 15:1. Burns cooler, making as much
power on the 100th lap as on the first. Late Model Plus has fueled the World of
Outlaws Late Model Series champion for three consecutive years through 2008,
numerous winners of the World 100, Eldora Dream, Dirt Track World Championship,
Show Me 100 and Colossal 100, as well as many other crown jewel events and
series championships.
VP113
Offering substantial
power gains at a competitive price, VP113 is oxygenated to street gas levels.
Formulated for naturally aspirated engines with CRs up to approximately 14:1.
VP113 makes up to 2% more power than competitive 110 octane fuels, with gains of
3-4% in engine applications with poor or marginal fuel vaporization qualities.
Its oxygenation also yields a higher effective octane rating and greater
protection against detonation. May require a tuning change, including increase
in jet size, for optimum performance.
U4.4
If you’re
not bound by fuel rules, this leaded fuel is the best choice for virtually any
powersports application, offering the biggest gain vs. cost of any performance
part you can buy. The latest generation of our U4-based fuels, U4.4 makes up to
6% more power than pump gas across a wider range of applications than its
predecessors. It yields no sticky residue and is more resistant to heat.
Designed as a direct, pour-in replacement for pump gas, it will require modest
jetting changes, i.e., +2 main jets or +2 pilot jets at most. With its higher
octane rating, U4.4 is designed for use in stock and modified 2-stroke and
4-stroke applications. U4.4 passes fuel rules for AMA Pro/Am, CCS, WERA, AFM,
NMA, WORCS, SCORE and Best in the Desert as well as club level racing and more.
VPR
VP's latest fuel for 4-stroke powersports
applications, VPR, bridges the gap between pump gas and race fuel. The ‘R’ is a
nod to ‘riders’ of motorcycles, quads, UTVs, & SXSs that may not require
professional grade race fuel, but are looking for performance that is
economically practical. Offering 1-2% more power, better throttle response,
increased consistency and long-term savings over pump gas, VPR is clearly what
your stock (or slightly modified) bike needs. Ethanol-related problems will not
be an issue with VPR and you can expect better vaporization, plus a cleaner,
more efficient burn than that of street gas. VPR will extend the life of your
engine, increase the time between rebuilds and lower your long-term costs,
preventing corrosion problems in EFI or carbureted fuel systems in the process.
