Our Mustang was dyno tuned on Torco and 93 octane fuel in 2011. It made 742 HP at the rear wheels. That translates to roughly 900 HP at the crank. The race tune uses 48 oz of Torco to 15 gallons of 93 octane fuel and this equates to 103 octane according to their blend chart. Torco is for unleaded gas and will not effect or damage sensors or catalytic converters. Our car still retains the OE emissions equipment, high flow cats and O2 sensors. So, Torco was the right choice for a newer car with this type of equipment. We had been purchasing it in a five gallon pail, but eventually the cost savings was outweighed by the convivence of the 32 ox cans. Summit had a descent deal on 6 cans last time we bought it. Pouring out the 5 gallon pail into smaller cans gets old fast. Also, we just don't use the car enough anymore to have that much additive around. It can go bad after several years of sitting. We have the remnants of a pail here that went bad and have no idea of how to dispose of it. Cheryl
I've had a lot of success with Boostane and Torco in my turbo cars, expensive but flat out works, zero detonation at 25psi when added to 93 pump gas. would even work better on an NA car.
We used to get that toulene in 55 gal drums for printing, mainly called Type Wash, we use it to cut the dried ink off parts and would hand clean ink rollers with it too. You know when you done using this stuff it can make you loopy so watch fumes or getting it on anything as it will melt paint. Can probably get this thru printing supply stores or a chemical company.
Several years ago I was incredibly fortunate to have about a 1-hour phone call with an expert from Sunoco's race fuels division. In a nutshell- add Xylene or Toluene. They are rated at 115 and 117 Octane, so you'll get a proportional benefit. The primary chemistry of gasoline is called the "BTX group" (benzene / toluene / xylene) so these are already components of regular gasoline anyhow and won't do things like damage rubber fuel hose, etc. Also - as I recall, Xylene will slightly dampen (slow) your combustion (allowing you to advance your timing a bit) and Toluene will slightly accelerate your combustion (requiring you to retard your timing a bit), but in either case the increased resistance to detonation will help. Do not add more than about 25% - 30% of either one though. So if you have a 10-gallon fuel cell I'd keep it at maybe 2 gallons of either one. Otherwise you are diluting the rest of the gasoline too much. (At the time he mentioned that there are about 175 chemicals in gasoline). As I understand, the primary benefit of acetone is only for droplet size distribution & surface tension which will increase efficiency but (as far as I know) won't affect the chemical "octane rating" of your gasoline. When I run nitrous, I add about 2 gallons of Toluene (since that's easiest to obtain) to my 1/2-full 20-gallon gas tank as my "poor man's racing fuel". -Bob C.
I run half tank of lacquer thinner in my go-kart one time,...ran like a raped ape for a few min haha,..or at least as a 10yrold kid I remember it that way ha
E85. If you’re running a Holley or efi. Cheap race gas. Drive on it every day and helps keep car cool.
"Cheap" race gas? What's your idea of "cheap"? It's pretty spendy in S.C.! Up till maybe a decade ago the Union 76 stations had 100 octane at the pump for four bucks/gallon. But those stations all gone, sadly Ranger Aiken, SC
My TTA was happy with 90 octane alcohol free pump gas and a bottle of Lucas octane booster. That car has a knock sensor with a gauge, it I did not run the octane booster, I couldn't run over 10 pounds of boost, with booster I could run all the boost I want. A 9:1 motor becomes a 13:1 motor with 20 pounds of boost. They sell it at Walmart for $7.50.
He means converting to E85 fuel. No additives needed, E85 has an octane rating between 100 and 105. Gas mileage is worse though because E85 has less BTUs than gasoline.
I hear you my friend. I use VPC12 in my Chevelle. 75 a pail at track. 100 local. I bought a Mark Sullens E85 carburetor to use next season.
Wow! Thanks so much! I think Lucas has a pretty good line of products. Their rack-and-pinion sealer has been a miracle-cure for me and my customers for a new years, now. Ranger Aiken, SC
The downside to E85 is availability, system maintenance and fuel system capacity upgrades may be required.
Works fantastic. Many people here on Long Island run it daily in muscle cars and race cars with great success. And it helps cool these engines down as a second benefit. Works with both low and high compression and of course boost friendly. It’s cheap and plentiful here.
There’s not much to it. Friends use it for years. Tear your carb down every year or two. Check your filters. Not much different than e10 pump gas we use now. The problem is with methanol. Not E85. Smart thing to do is clean air bleeds with carb clean if it sits a couple weeks. That’s pretty easy.
