Monday, February 15, 2010 VP INTRODUCES NEW U4.4TM RACE FUEL FOR MOTORCYCLES, OTHER POWERSPORTS



Cost-Effective Performance Gains Include More Power, Better Throttle Response

VP Racing Fuels, the world leader in race fuel technology, today announced the latest generation of its U4-based fuels - U4.4TM. Designed for stock and modified 2- and 4-stroke applications, U4.4 offers more power across a wider range of applications, better throttle response and is less sensitive to heat than its predecessor U4.2, according to Steve Burns, VP's President and Director of R&D. “With horsepower gains up to 6% compared to premium pump gas, U4.4 is comparable to VP's best AMA Pro level race fuels for less than half the cost—a relatively inexpensive way to generate additional power.”

"U4.4 is designed as a direct, pour-in replacement for pump gas,” continued Burns. "It will require a modest jetting change—up to 2 main jets and 2 pilot jets at most, so customers can essentially 'pour in the power' and be on their way."

"Historically, generating maximum power from a motorcycle fuel required trade-offs in other areas, for example, residue build-up in the carburetor, vapor lock or other issues," added Burns. "With the new technology in U4.4, there are no trade-offs. It causes no residue build-up, will be more resistant to heat and will yield the most cost-effective power gains of any performance part on the market."

"U4.4 is ideal for engines with 10:1 to 13.5:1 compression," Burns continued, "and with its Motor Octane of 103 and oxygenation, it provides excellent detonation protection." U4.4 is designed for all 4-stroke applications, and because of its higher octane rating, it's appropriate for all 2-stroke applications as well. U4.4 passes AMA Pro/Am fuel rules and is perfect for CCS, WERA, AFM, NMA, WORCS, SCORE, Best in the Desert, club level racing and more.

Use of U4.4 will yield faster and more responsive engines without harming carburetors, O-rings or gaskets like some other race fuels will. The cost effectiveness of its performance gains should not be underestimated, according to Burns. "For example, a costly new exhaust system wouldn't generate as big a power increase and its increase would be on a smaller slice of the RPM range, while U4.4 produces power gains at all RPM levels," Burns said.

Regarding the evolution of its U4 product line, Burns concluded, "There are always improvements that can be made. We'll never be satisfied until we've explored all options for providing customers with the best technology and performance possible, and we have the ability to move quickly to introduce the newest technological developments to market. Making the best performing fuels is what we do for a living, and we’re pretty good at it."

Over its 35-year history, VP has earned a reputation for producing high quality racing fuels with superior power and consistency—as illustrated by its sweep of all AMA Pro Racing Championships in Superbike, Supercross, Motocross and Supermoto for five consecutive years through 2008. VP is also the official, spec fuel and/or contingency sponsor of AMA Dragbike, AMA Flat Track, AMA Motocross, AMA Supercross, NHRA and ADRL among more than 50 VP-sponsored sanctioning bodies. - vpracingfuels.com.

I never had any issues with the 4.2 I used for the last 2 seasons. Cool though, looks like they made some improvements to it.

WIsh they would make a 'cheap' pump replacement fuel rather give VP money than government in form of gas taxes. Consistent 93~95 no additives just good ole petrol like we used to get. $4 bucks a gallon would be fair, rather it would be cheaper but I'm realistic.

Do you use it in your 4stroke or 2stroke?

I was lucky enough to have hand in pre release testing...

It's an excellent fuel, very similar to 4.2 just evolved to the "next level".

Can you give us a price per gallon? Like say if we were to buy it at the Cycle Ranch MX near the VP HQ?

Thanks.

Will it gum up the carb if you leave it for more than a couple days? That Ultimate 4 could really fuck some stuff up. Ran good though!

U4 gumming stuff up hasn't been an issue for a few years. The additive that caused that problem was removed early on.

As to U4.4...

Lots of ENERGY. Plenty of Oxygen.

Very clean burning. The new Injected bikes seem to love it.

I tested it last year in a KX450 and a KLX450 (Set up like an '08 KX-F motor). Both bikes loved it and ran jus' a little bit cleaner off the bottom than they did with U4.2.

The U4 products are the best Race Fuels for the Money.

Period.

I thought this was already out? I haven't bought race fuel in awhile but I heard about it awhile ago I'm pretty sure?

4.4 has NOT been formerly released till now to my knowledge.

Loretta's was the original goal to release...but I guess it just didn't happen.

It probably retails over 10 a gallon...not sure on that to be honest. They used to offer a refund for the metal can, but that went away...so instead you buy the fuel plus 15 for the 5 gallon can. If you can find a place that pumps is from a storage tank..and is smart about storage (no air contamination etc..etc..) then your good to go.

Formally released?

Yes, it is...as of the Indy show.

You may not find in stock for a few weeks.

When we ran it we were testing...it had a funky name that was all numbers and it was Red.

It should come in, price-wise, right along-side U4.2.

Sounds like they loaded it down with more Ethanol, or Methanol.

They surely arent using MTBE in CA.
