Nutec race fuel
Posted April 05, 2002 - 06:39 AM
Well I have just completed a fuel test to include several versionsofthe Nutec product.I normaly run Cam 2, andwas very happy with it, However. I first did a dyno run of Cam 2, then we went the Nutec GP-2,and got a small increase in bottom end. Next we tested Nutec special 4,and WOW we got 3 horsepower increae. This stuff is incredible. But the down side to this is, the cost at 15.00 a gallon, and it's HARD on the motor. In case you ever wanted to know. Dave

Is the tests compiled against say 91 octane fuel from the pumps ?
What is the summary of the test cases you have run through ?
What Test Cases did you validate on these summaries.
Comarison between race fueles and standard fuels
Sorry its my job to look at this kinda stuff in a relitive manner differant industry though
At 15 bucks a gallon, it would be nice to see full figures on why spend the money (Right Shawn)

I did not mean anything (No Offence), my career is based on research and development. It is a very bad habit of mine to want information. I think if I were a Hotshoe and racing I would venture into the world of 15 buck a gallon fuels. But since I am a washed up balding ol`fart haz bin the Buck 80 91 octane is just right for me.
I like numbers and info so What I would say is since your bike is pumping iron, what are the Mods that you have done aka piston, stroker Cam or ??
This would be the Test Spec
test Case would be the senarios you ran the bike under
Test Summary would be the conclusion of the Data gathered and evaluted from the spec and case.
Man I am a stickler for perfection
Goo info though thanks for postig it

Can you please explain how it is hard on the motor?? Corrosive?? Eats seals?? Heat??
VP MR-2 is also oxygenated. Do you have any experience with it?? Is it hard on the motor also??

You have to jet accordingly though.
I tried it in my 426 and it didn't seem to run that well. I have a Yosh pipe, airbox and done the BK mod. The best I've found for the 426 is VP motorsprts 103.

The fairgrounds hosts every Friday Night and some wekends Sprint racing, thats why the 76 racing fuel in some Stations.
I mention this in case you have a regular raceway in and about the area try and scope the 76 stations and see if the ones close to the track have the 102.

How long have you had your motor wet sumped? I just had mine done last week. My question to you is are you going over 1 hour per oil change or do you have a practice bike? Any adverse reliabilty yet? I put about 1hr fifteen minutes on mine this past weekend. Bike ran fine, but the oil was spent. Would appreciate your insight.
I am very happy with the weight saving...you can really feel the difference on the bike. MXA made the whole changing the oil thing sound so difficult...I found it to be as easy or easier then stock....having a small funnel is essential. Getting the DrD CF airbox this week....can't wait to see if it makes as much difference in the handling (wt. wise) as the wet sump.
Let me Know..thanks

Not to seem skeptical I do believe that it is possible to get a 3 Horse gain especially on a bike that is creating 45+ horsepower. But when you are only comparing the NUTEC to CAM2 it is not a very thorough test.
Now if you had tested a few different blends of VP, 76, Trick etc. I could understand. I just have a feeling that VP makes a gas that is comparable with the same results or close.
Also at 15$ a gallon that is way way to steep, I hope at that price it comes in the cool little painted drum and not just a Blue can.
Well to this point I have had no need for Race Gas on my 4 stroke just a shot of VP octane booster but I personally run 76 110 Leaded in my 2 Stroke at 6$ a gallon.

I see $15 a gallon fuel all these mods on a bike that hauls anyway for MX applications.
After reading all this hoopla I went to about the fastest guy I know around here on the east coast. (Actually the reigning 25+ A and 30+ A national champion.) and asked what mods and fuel he runs. I think he runs a Big Gun pipe (Not a plug for them because I run DRD. And this is only because I just bent my stock one all to pieces.) and some suspension work. For fuel I believe it's 85 octane in the winter and 89 in the summer. I can promise you, if you watch and hear his bike go around the track there won't be many that go much faster anywhere. (Outside the nationals.)
If all of this is tinkering because it's a hobby, then more power too you and I think it's great. I just wanted to post this because there are people out there in my shoes reading all this and trying to figure out what they should do to make their bikes run sound. Just read the manual and run Premium pump gas. (Unless of course you are mod'ng the bike and they require the extra mods.) But if you feel you need this for an edge, just go check out the bikes of the fatest guys at your local tracks and see what they are doing.
Again, for all the persons on here, I'm not attacking you and all this stuff you are talking about is great. I'm posting this for persons like me who just want their bike to run solid and not want to rely on mods to give them an advantage but more so want to make sure the bike doesn't break down or run improperly to put us at a disadvantage.

1st Yamaha designed the bike to run with the highest lowest Octane, They have to, us nim rods who just run stockers on the weekend would buy soemthing else if 115 octane was the norm.
I like Lawdogs tests though good insite and good info for the Racer who wants the most from his bike. Again common sence is needed here to distingush what Lawdog has posted and what is best for your bikes.
Personaly I would not spend 15 bucks a gallon on Gas, ( would pay 42.95 for a spanner wrench thoug Eh Hootna)
even my emntioning 102 octane from 76 @ 5 bucks is a stretch for me so I will stick with my 91.
KFrosty I would bet that the Fast Dude you refer to has his bike dialed to the letter. But I do find it hard to believe 85 Octan though, No Diss just have a question marc on that one.

Anyway I usually eat at Super tacaria for all the race gas I need prior to riding

So I now must tune myself down or risk being banished by the Red Thumper God!!!
Well then again we got in trouble on the 426 board too. Man we are batting a thousand..
Maybe we need to go pay the KTM board a visit and give that moderator a fit.

Ya the diagnosis was lack of Baa&&^&llls
Wuzz That got to doo with Race Fuel
Anyway if and when we hook up at hollister maybe we should duel to the finish

Ego has got a serious point about $15 a gallon gas. If you understand how gasoline works, you'll understand why Nutec at 90 octane makes more power but is harsher than the 110 octane. Im thinkin the chemical make up of the 90 octane is heavy with trichlor-ethylene (which will desolve aluminum not unlike true Ethanol)and Methyl Ethel Ketone. Both of these carry very high levels of available BTU's. Both very hard on engines, but make a ton of power. Understanding how octane ratings are achieved is also key when deteriming what fuel is best for which applications. Motor octanes are very different that research octanes. The pump octane ratings are achieved by averageing the Research and Motor octanes. Problem: Motor octanes are developed by testing done at 4000 rpm and research octanes are developed at 1500 rpm. Which do you think are the most important for a racing spec? Problem 2: What if your average octane 92 gas is something like 100 research and only 84 motor? Bad gas, but its still 92 average octane gas.
The best of both worlds, I cut my race gas with 92 pump gas. I run like I said, VPc-12 or trick 108@50%. Saves me a ton, my bike starts easier, eveabody happy

Also, I need to learn the difference between their's and there's.

I do appreciate all of your input,and all I was trying to do was give some insite on a new fuel that hit the market.I do believe that VP makes a very comparable fuel (MR-8),and it works very well. If you guy's don't know,I am a quad rider,and compete on the Pro level. I am the fastest guy around here,on a quad, and on the national level I need everything I can get. Where isthe one place you can pass 19 quads a once??? The Hole shot!!! Stock 426's run great on pump gas, but I can't leave any thing to chance. I hope I haven't offended any one, just wanted to post some info. Later Dave
