Torco Accelerator

Has anybody ever heard of this stuff or used it?

Looks like it may cost more than just buying race fuel???

I race in a class where you are not allowed to use race fuel. I was trying to get the octane level up on my 93 octane pump gas. Not real sure how good that octane boost you buy at the parts store works. I have tried up to 3 bottles of the octane boost from the parts store in 5 gallons and I don't notice any difference.

are you getting detonation? if not then your not gonna do any good adding octain

whats you build?

Its my brothers motor, it is a 460 bored .060 over, flat top lightweight speedpro forged pistons, eagle rods, balanced, c8ve heads home ported using scotty's web site, 2.20 and 1.76 manley stainless valves, cam research solid lifter cam 530 lift on both with 222 and 224 dur. at .050 with 110 ls due to vaccum rule, 1.7 crane rockers, guide plates, 3/8 pushrods, scj intake and exhaust manifolds, 2 1/2" exhaust pipe into a 3 1/2 Y pipe, prosystems 1000 holley carb, it is not zero decked the pistons are about 20 in the hole, wish he would have 0 decked it.

Yes it has detonation, I have turned the timing down until it quite pinging but it runs like crap at 18 degrees. The distributor weights are welded out since it is race only. I tried a distributor with light springs in it that advanced out at 2400 rpms, but it still pings. He is using the hot plug right now and is going to try the colder plug and see if that does anything. He is using 91 octane pump gas right now since that is all they have in his town.

It only has detonation at the initial hit of the throttle, at 34 degrees of timing the detonation is their at just the initial hit of throttle.

Am I on the right track, any input will help him?

"I race in a class where you are not allowed to use race fuel."

Can you run a mix with a some AV Gas 100LL? Or is it just pump gas and 1 quart adatives that are legal? Mixing some 100LL in there would solve it.

What about getting some thinner head gaskets? .025 ish commetics? That will get your quench right and talk with a cam grinder about cam event timing, the cam you have is to small and holding to much cylinder pressure. Maybe talk with Dave Mclaine or Brett Powell about camtiming for your application and rules.

Also talk with them about distributor set up, their a couple of tricks for vaccum rule stuff to.

The rule just says no race fuel.

Technically speaking, aviation gas isn't race fuel. How close do they check the gas?

Might try the cosmetic gaskets I did not know they went that thin. Do you need to prep the block for those or will the factory surface on the block and heads work?

The cam is custom ground for the engine the vaccum rule is why it is so small. Even a custom solid roller cam from cam research was not any bigger it just had more lift. Scott Main at Cam Research told me where to degree it in to run its best and that is where I degreed the cam at. I talked to Scott at RHP about getting a custom distributor and he thought the welded distributor was best.

They don't use a tester, as long as they don't smell race fuel you are good.

If they are testing by smell, I'd mix in some 100LL as suggested. I'd love to have them tell me they could detect race gas by smell....that's a good one.

It is very, very effective and of value if it fits your needs and rules.

Most off-the-shelf octane boosters that you find in your local auto parts store are highly ineffective relative to your performance needs. If you look close to these "octane boosters" labels they claim something along the lines of "increases octane by 10 points!" BUT if you read the fine print their points scale is something like 20 points equals 1 motor octane point. In other words, they are ineffective octane boosters for high performance needs.

Torco Accelerator is supposed to be a highly concentrated form of the same chemicals that Torco uses in their race fuels, and so if you add it to pump gas it kicks up octane big time. It costs about $20 per quart, and 1 quart treats 10 gallons of pump gas making it 102 octane (ask them if this is Motor Octane, Research Octane, or R+M/2 Octane). At $20 per quart added to 10 gallons of fuel, that increases fuel costs by just $2 per gallon, which is not bad at all if the resulting anti-knock index meets your needs.

Depending on how pump gas fuels are tested at a "pump gas spec fuel" racing event, this blend will probably fail the fuel test.

I wouldnt waste my time with one of scotts distributors for vac class rule racer, talk with Brett Powell. You need to speak with someone who does those motors. Like I've said their are a few special tricks to make them work and make power.

You may try retarding it a degree or two and see if the detonation goes away. You could be right on the line.

Thanks guys, my brother will have the torco additive this week some time. Will give it a try and let everyone know.
