Whats up guys, I have a few questions about torco. Well for starters i have a 2.8 behemoth (regular inlet on now). Im at 18lbs now. Im looking to get a way to run the blower in the 22-25lb range. Yea race gas would be an option but im not fond of storing that at my house. Im looking at the torco because it easy to store and easy to carry say i run out of gas and have to fill up. I tossed around the idea of meth but alot of people say not to use it. We do not have e85 readily here so thats out the question. Any suggestions you guys have will be greatly appreciated.

Yea i used to work at an exxon (refinery not gas station). One of my jobs was to rate the gas (r+m)/2. I was in the process of formulating the mixture with the blend guy there before i left for resigned. I was going to try one gallon to 10 gallons and from what i research it would have came to be about 98-99 octane. I still may try this and get it tested. The only thing is that im not sure but adding the additives to make it safe to run.

You can make it as much as a 30% ratio.

FORMULA 1
Toulene
R+M/2...114
Cost...$2.50/gal
Mixtures with 92 Octane Premium
10%...94.2 Octane
20%...96.4 Octane
30%...98.6 Octane
Notes: Common ingredient in Octane Boosters in a can. 12-16 ounces will only raise octane 2-3 *points*, I.e. from 92 to 92.3. Often costs $3-5 for 12-16 ounces, when it can be purchased for less than $3/gal at chemical supply houses or paint stores.
FORMULA 2
Xylene
R+M/2...117
Cost...$2.75/gal
Mixtures with 92 Octane Premium
10%...94.5 Octane
20%...97.0 Octane
30%...99.5 Octane

*NOTE* Toluene is much more expensive nowadays. Looking into it further, Torco is probably a cheaper alternative, but doesn't compare to Toluene when resisting detonation, even if theoretical octane #'s are the same.

Lucas oil Octane booster has the same MMT ingredient that Torco has. 1 bottle to 10 gallons of 93 octane will give you 96 octane. 1 bottle to 5 gallons or 2 bottles to 10 gallons will give you a little over 98 octane. The great thing about Lucas Oil's Octane booster is that you can buy it at any major auto parts store. I ran it for quite awhile with nitrous and had no problems.

Where do you get toluene for 2.50? I looked everywhere and it was around 15/gal

I think he's talking about the cost of the amount of toluene per gallon of gasoline for the mixture process. Just to compare it to the cost of Torco or race fuel.

I have a KB 2.8H. I run 20 psi at (4300 ft altitude) 23 degrees timing 9.5 gallons of 91 to 32 oz of torco. No issues what so ever. My understanding is I am at 96 octane
I think your octane may be significantly higher. According to Lethal's and Torco's sites, 10 gal of 91 and 32ozs of Torco is 102.

This is what I have been able to pull out of other threads hopefully this is helpfull:

Originally posted by RWTD:
93 Octane Pump
17 lbs (3" upper) - 20 degrees
19 lbs (2.75" upper) - (not generally recommended; although *many* run 16 to 18 degrees without issues)
21 lbs (2.75" w/ 2# lower, or 3.0" w/ 4" lower) - not recommended
98 octane
17 lbs - recommend 96 octane.
19 lbs - 23 degrees (I'd say the perfect octane mixture for this pulley combo).
21 lbs - 21
22 lbs - 20
104 octane
17 lbs - too much octane; would require more than MBT spark to keep power from being hindered.
19 lbs - too much octane; would require more than MBT spark to keep power from being hindered.
21 lbs - 23 degrees (recommend 101 octane)
22 lbs - 23 degrees (recommend 102+ octane

Torco "Accelerator" Octane Mixtures
5gal of 93 with 32 oz of torco = 101
5gal of 93 with 64 oz of torco = 101+?
8gal of 93 with 32 oz of torco = 99
8gal of 93 with 64 oz of torco = 101+?
10gal of 93 with 32 oz of torco = 98

15gal of 93 with 32 oz of torco = 96
15gal of 93 with 64 oz of torco = 99

91 Octane Blend Chart from Torco's Website. 10 gal 91 + 32 oz = 102. Blend charts for other octanes are also on their website.

I have heard that Torco's numbers are overly optimistic. So just keep that in mind.

Agree! The post that caught my attention and prompted me to post the Torco numbers was the 20psi/23* tune on 9.5 gal of 91 + 32 oz of Torco estimated to be 96 octane. I think the octane is higher than 96 to support 20psi at 23* (more like 102). Regardless, tune it with a mix and stick with it.
