Ratman, I'm not trying to say you're wrong, but here's the math (and math never lies)

1 gallon of 110 octane UNLEADED mixed with 20 gallons of 93 Unleaded yields 21 gallons of 93.81 octane brew.

Using leaded 110 will give a teeny bump to, maybe, 94.0 tops.

I raced and tuned two strokes for a looong time. MX bikes run just fine on pump gas, even when modified with porting and pipes. Adding octane to them can keep you out of detonation if you've missed your jetting to the lean side, but it usually isn't needed. Two stroke roadracers are set up for race gas, and "104+ octane booster" won't keep them from chicken-tracking the pistons. The way I look at it, is you either have a pump gas motor or you have a race gas motor. It just gets too hard to keep track of for all that "middle ground"...

i sell a product for race cars. its called Torco. i run 17 psi boost on the street with it to keep any chance of detonaion down.93 turned to 104 octane its unleaded and acts like a race fuel. i have used for three years and now i sell it. check it out on there site [url]
http://www.torcoracefuels.com/torcoenter.htm

i sell it for $69 a case and will treat up to 120 gal.

look under the accelerators way better than all the others i know i have tried them all

UNLEADED & LEADED ACCELERATOR, RACE FUEL CONCENTRATE.




--------------------------------------------------------------------------------



Torco Race Fuels is the first and only race fuel manufacturer to produce a real race fuel concentrate that performs like a race fuel. This product is not an octane boost; it is a race fuel concentrate that transforms a 93-octane super no lead up to a 107-octane race fuel when proper mixing instructions are followed.

There are many different variations of blending the concentrate to suit the customer’s needs:

--------------------------------------------------------------------------------



--------------------------------------------------------------------------------

1. Blend the Leaded concentrate with 100 low lead aviation fuels to get up to 112-octane race fuel that really flies!!!!

2. This concentrate when blended with a race fuel makes a Nitrous fuel to fit many applications.

3. The Leaded concentrate makes up to a 106-octane race fuel when blended properly. Plus giving the needed lubricity of LEAD!!!

--------------------------------------------------------------------------------



--------------------------------------------------------------------------------

The Unleaded concentrate when blended with a 93-octane super unleaded makes up to a 104-octane race fuel for many of today's streetcars, motorcycles, watercraft, ATV's, and many other motor sport applications!



Take a case or two with and never worry again about not having a high-octane racing fuel for great performance for stock or modified application!!




OUTSTANDING PERFORMANCE WITHOUT HAVING TO CARRY A LARGE AMOUNT OF RACE FUEL!!!

Thanks mcollinstn and SMOKDU. That's very helpful.

SMOKDU, what would it take to turn 89 into 91 or 92. How much would one of your 'cases' treat?

Trying to do the math here to figure out if it's worth making "fuel brew" or just chaulking it up and going out of the way to the 91 pump.

mcollinstn, i was mixing high octane 110 leaded gas with 93 octane unleaded. ratman

Yeah, I understand, man.
But a 1 to 20 only raises you a full point. Possibly two on the outside.
Sure, the lead is a factor, and it works on diminishing effect so the first tad of lead has more effect than the next, and so on. But Leaded 110 doesn't have all THAT much lead in it. And your mix ratio simply makes it impossible to realize the huge gains many people assume they are getting.

Not necessarily a bad thing, though, since any additional buffer can take care of borderline conditions. And lead concentrate can have a pretty dramatic effect on its own, as long as you don't need more than 95 octane or so. It's just hard on sparkplugs (although boat plugs get changed often enough its not an issue) and fish.

The TORCO concentrate mentioned is probably the most effective "bang for the size" that you can legally obtain. Say you go on a long weekend where they only have 89 available. Obviously you don't want to drag a tanker truck along with you so the TORCO concentrate takes up the least hauling space and returns the best results. But once again, the marketing language used for that product is as misleading as all the others. The difference is that this stuff DOES have kick.

One 32 oz can costs about $17, but delivers the same end result as adding 3.5 gallons of leaded 118. (The leaded 118 at $7.00 per gallon will save you about $3 over the Torco mix due to the fact that you get "more fuel" by 3 gallons). But there is no denying the packaging benefit to the 32 oz metal cans that the Torco comes in.

<< from the ratio chart on the bottles >> note that the bottle shows a chart with 93 octane base fuel, so all numbers are dropped 4 to compensate.
32oz of Leaded Torco "Accelerator" Race Fuel Concentrate in 20 gallons of 89 will give you 93. (That's as good a kick as you can get in a bottle.)
32 oz in 10 gallons of 89 will give you 100.
32 oz in 5 gallons of 89 will give you 103.
This trend shows that adding 32 oz to 40 gallons of 89 *should* give you your 91 you are after. This corresponds to a price increase of $17 for 40 gallons, which is an extra 42 cents per gallon.

If you need a 91 octane minimum, you can clearly see that it is cheaper to find 91 around the lake somewhere than to "make" your own.

Best of luck.

Bingo. That's what I was looking for. Thanks a million!

3-4 months unless it's stabilized while it's still fresh. It's the air that ruins the unleaded fuel, and also sunlight, but there is no sunlight in the fuel tanks.

put a little DIESEL FUEL in that puppy, SEE HOW THAT DOES.

Does the Torco have packaging that allows you to keep it on the boat safely so that if you find yourself in a bind?

Maybe you can post a picture?

32 oz. Metal cans. Screw off caps.
