I have always wanted to try the new U4.2 which claims a 6% horsepower increase. Motorcyclist conducted a dyno test with a 1098 and only found a 2% increase from 143 rwhp to 146 rwhp. If you look at the graph there is a slight increase across the board whic is good.

So, I decided to check the price of U4.2. Well.....

5 gal = $63.61
30 gal = $429.23
54 gal = $632.60So at approx $12/gal I think it would rather just stick with pump gas.

However.....

Just in case anyone has noticed or was wondering there is a VP fuel station in selma. I have alway drove by it, but never stop to see what they were selling. Well on my way home from buying my truck I stopped by to see what they offered. They offer 100 octane VP Streetblaze racing fuel. I thought surely this stuff is just a higher octane pump gas like you see back east.

I did a little research and found out it is just your typical pump gas. Here read for your self.

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), StreetBlaze 100 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 StreetBlaze100 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.

This what is said about the U4.2...

The latest generation of our U4 based fuels, this fuel is a direct pour-in replacement for U4 with little to no jetting changes required - +2 main jets and +2 pilot jets at the most. Makes power equivalent to U4 with no sticky residue and a less pungent odor. Designed for stock and modified 2-stroke and 4-stroke applications. U4.2 passes AMA amateur fuel rules and is perfect for club level racing, CCS, WERA and AFM. U4.2 makes up to 6% more power than pump gas.

When I drove by the price for the Streetblaze was $6.87/gal. Now I know that is a little more than pump 91, but compared to what the U4.2 is selling it really isn't all that bad considering what is says it will do. Now it will give a little extra HP, but probably not 14%.

A station in Coalinga also sells VP. Not sure what types though.

I read a thread on the Gixxer board where a guy cited an article about 87 vs. 89 vs. 91 octane pump gas. The article claimed that 87 and 89 actually put up better HP numbers. If I can find the article I will post a link. Any comments on that though? Certainly you can only realize any good gains if you have a Power Commander and a custom map. Yes, no?

the higher hp with 87 or 89 vs 91 is because the lower octane fuels burn slightly faster. the higher octane in the fuel is to help slow the burn which helps with pre-detonation in high compression engines. higher octance is not always higher hp

i think it may also cause a problem for o2 sensors if any bike comes with them.

Calkidd,

Last time I check, Madera Honda Suzuki carried in their parts department VP race fuel. I believe it was 10 Gallons at $80. Guess that makes it $8 a gallon. Things may have change since. But check it out.

Guys I am not looking for a place to get racing fuel. I posted this for information as I was curious when I saw the VP station.

I think I will try the streetblaze just for giggles.

So does it matter or not? I find it confusing. The racers run more octane and get better numbers, so it has to help. But what needs to be done to make it most effective?

On topic: on a stock bike, would there be much of a difference between 89, streetblaze, or the expensive stuff?

When comparing the racing fuels to pumped gas you are comparing apples to oranges. Racing fuels are refined differently having additives which allow for better burning of the fuel ie oxidizers to oxidize the fuel. This in turns allows the engine to produce more power.

Octane is an additive that prevents detonation. The higher the RON # the more octane is in the fuel. So in theory Will is correct if your engine does not require the higher octane you can hinder the ignition process rather than help it.

If you exceed the octane requirements of the motor it can hinder performance. Octane is only the measurment of a fuels resistance to spontaniously combust (knock and ping) given heat and pressure i.e. the compression stroke. Octane is not a measurement of the power potential of the fuel, that would be BTU's. Increasing any of the following three will increase the need for octane 1) compression, 2) timing, 3) boost. If you have done none of these modifications to your enging you do not need more than what the manufacturer reccomends.

http://auto.howstuffworks.com/question90.htm

actually, R+M/2 is the equation to figure out the octane rating... but yes, there are additives that they put in gas to raise it's octane rating... the additives are not called octane...

going by what tat website is saying, 110 octane race gas, would be 110 percent octane!!!:eek:

that would mean there is nothing else in the gas but octane... and they got an extra 10 percent shoved in there somehow...:confused::rolleyes:

Oct or 8 eight
Tane or chain of hydrocarbons

octane - chain of 8 hydrocarbons

in diesel it is cetain or chane of 10 hydrocarbons

R = research octane or chemically measured octane
M = motor octane or mechanically measured octane

(R+M)/2 gives you the average of the two measurements
This is the American method of displaying the fuels octane, in Europe they do it a little bit differently and will yeild a higher number for the same fuel.

In gasoline octane is altered with different chemical additives.

Always change your fog light fluid, blinker fluid and muffler bearing at the same intervals. So as not to void the warranty. Most dealers recommend every 3 thousand miles with the oil changes.

My 749 R needs a new wiper blade and I was thinking about those high dollar clear silicone ones. Any thoughts? While I was at it I was thinking of upgrading to the 420cc silicone ones too.
