Thank you for the information. It seems torco or lucus is the best alternative to race fuel

+1 on that !

Lets discuss financials-when raising octane it is ALWAYS the cheapest to start with the highest pump octane you can buy-ie 93 IF available
as far as cost to raise octane-the cheapest way to raise octane will be to add race gas or Tolulene IF available-lets say you want 100 gallons of 96.5 octane:
you buy 81 gallons of 93 octane-you want to see 96.5-you buy 19 gallons of 112 oct race gas at 7$ a gallon-puts your octane at 96.61-cost 133$$ BUT you would have paid 76$ for 19 gallons of 93 at 4$ a gallon so it really only cost you 57$ to get octane from 93 to 96.6
almost same cost-you buy 99 gallons of 93 octane, at 100-1 you add lucas , it will take 128 Oz's (9) 15 oz bottles at 6.50 a bottle= 58.50$ minus the 1 gallon you added at 4$=54.50$
Torco "Booster"-will take 140 oz (5 32 oz cans) added to 99 gallons of gas-will cost you 110$ at 22$ a can-minus the 1 gallon you added at 4$ a gal actual cost would be-106$
NOS- at the 80-1 mix it would take to get 100 gallons of 93 to 96.5 it would take 80 oz or 7 12 oz cans-would cost 105$ (minus the 4 $ worth of gas it would replace) actual cost of 101$
From everything I have read-if you want to raise octane even higher you can pretty much forget about adding bottles of octane booster becuse it does NOT raise ovctane linear like adding Race gas, tolulene or Xylene will , you have to double/triple the amt of octane booster to even gain another couple of numbers, it would quickly get very expensive. On the other hand, keep in mind when you are boosting your octane with race gas or Tolulene, even at 7$ a gallon for race gas you are replacing a gallon of premium that would have cost you 4$ anyways so its really only costing you 3$ a gallon for race gas. For anyone that want to figure mix ratios of 2 different octanes that hasn't figured it out, simply take the amt of base gas-say 90 gallons of 93-90X93=8370 then take the gallons of race gas-lets say 10 gallons of 112 -10 X 112=1120 then add them together and divide by total number of gallons-8370+1120=9490 divided by 100=94.9 octane, you can move the numbers around all you want to find your requirements, Smitty

VERY GOOD RESPONSE, THIS FORUM IS REALLY STATING TO FILL UP!!

This sounds pretty decent from a cost standpoint??

I start out with AVGAS 100 octane as a base. Its about $5 a gallon, depending on area
.

Torco is must cheaper in 5 gallon drums.

Tyson, are you sure of these numbers because they do not add up to me. I do not see any way 2 gallons of 114 octane toluene mixed with 51. 7 gallons of 87 octane fuel would give 110 octane fuel. From the little I know about this I figure it would take around 46 gallons of toluene and 8 gallons of 87 to make 54 gallons of 110 ocatane. This assumes that it is all linear for the octane rating when mixed together. Is lead also involved? Something else? Since the components you noted only add up to 54 gallons, do you know what the other gallon is?

Drums are only filled to 54ish gallons.... Room for product exspansion!

Better check your numbers as the final octane of the mix ypur describing would be 87.5 , the math don't lie, Smitty
