Sunoco Fuel

[klebs01]

With the AMA requiring spec fuel, is anyone racing CCS planing on running that fuel?  I just talked to BFR and they said they are looking into carring it if people are running it.  I'm just looking to see if its worthwhile to set my bike up for it.  Seems a lot more economical than VP or R-tech.

It makes less power than pump gas.  Go to Road Ranger or to Flying J and buy that gas.  It will be more economical and give better performance than the AMA spec fuel. 

What you need is some consistency.  I've used R-Tech, Power Mist, VP, and a list of other fuels.  There is power to be had, but it comes with expense.  What you really want is an oxygenated, leaded fuel.  Whether you do that by purchasing it or by making a combination of street and a race gas, find something that you can stick with and develop some consistency with.  A  112 leaded non oxygenaged Sunoco, Turbo Blue, VP, Power Mist isn't going to be a great choice in most production motorcycles.  And an unleaded 98 to 104 racing fuel just doesn't have much carry in the rev ranges that most bikes operate in. 

That give you some ideas, Nathan?  You riding your SV again?

Yeah, I'm riding the SV agian.  Right now its with 4 and 6 getting a little work done.  I'm just looking at a lot of options for fuel.  It seems like there is some benefit to not running pump for tuning, but $30 a gallon for ProV1 seems excessive.

we ran the sunoco last year in moto st and it didnt make any more power then pump gas on the dyno.
it cost twice regular high test pump gas.
I ran some in my 600 during CCS weekends and think i used some towards the end of the 200 last year.bike ran fine on it. but i plan on pump gas for the ASARA team challenges compared to sticking with the sunoco for the moto gt bike

but you will be racing against people running race fuel they might have an advantage in the fuel department.

plus it was a pretty blueish green color fuel

Unless your running AMA also, which it looks like your on an SV so not the case,not much need in tuning your bike for their spec fuel which will give no more power then pump, just cost more.
VP U4.2 will give you good horsepower gain at about $15 a gallon as it is highly oxygenated.

I am seeing some bold unsubstantiated claims concerning fuel here.

Let me qualify this by saying: I currently do not sell any fuel at my shop, nor do I have any vested interest in any fuel company.

While I personally have not done exhaustive testing on our dyno concerning all of the different fuels currently available, We defineltly have done some testing.

How a race fuel reacts in your motorcycle really depends on the state of tune of the motor. If you have a bone stock motor, you will not see the benefits of several of the race fuels available.

So to make a blanket statement tha a fuel does or does not do something without qualifying that statement is very irresponsible.

We have tested the sunocco AMA spec fuel  atour shop and found very favorable resuts on a AMA spec motor on a 600cc motorcycle. What I am saying is that the Sunocco fuel is good enough to use in a built motor. with minimal loses in power compared to a similar VP blend that we have used. But yes, The most exspensive VP fuel does indeed make more peak horsepower.

We've ran R-Tech and VP and I really like the R-Tech it burns a lot cleaner and makes just a tad more HP...the ProV.1 does.

That being said...run the R-Tech outlaw...it's cheaper than ProV.1 and has more oxygnation....it was just illegal in the AMA.  It's going to work a lot better than Sunoco.

Matt, care to tell me what compression your AMA spec motor is?
We run close to 15:1 on our 650's.
The spec Sunoco fuel made 2 hp less than VP C12, no matter how we mapped it.

on a different note you guys running Moto Gt this year?

[Super Dave]

Not me.  Focusing on just my racing program this year.  First time since 1992.

thats cool running the buell still

[Super Dave]

thats cool running the buell still

Yeah, I only did two events on it last year.  Full deal this year.  Not sure exactly what.  Need normal work first.  But I have some ideas at least...
