Well, the RCR Stage 1 kit is working good. I have noticed that it uses more fuel-so the more fuel, more power idea is true.

I run 87 octane stuff that comes out of the barrel that we use for the lawn mower. Nothing special at all. Should I get another small barrel to put some "better gas" in for my Scrambler?

The Amaco place in town sells that 92 octane supper-clear gas. Would that be better now that I am running a performance exhaust?

What do you guys run with your performance exhaust equipted machines? Thanks.

Take your head off send it to rick ritter and have it set for pump gas (92oct) and feel the power. if u run 92 oct in it now it might run a little rich in hot weather due to 92 oct burns cooler.

Higher octane gas is made for higher compression engines. It resist detonation better. If you have not done anything to the internals of your engine, then I would not waste the money on higher priced gas.
I have not had a ton of riding time on my RCR'd quad, but the regular gas seems to run just fine.

About sending my head to Rick Ritter, what increase in power do you get? How much does it cost? Is it worth it?

It should give you more punch all around. I think its $50 im not sure. I know when I went to race gas I had alot more torque. YES it is worth it.

Lurch is correct.. Higher octane gas has one purpose. It is actually, harder to burn, that is why it helps with detonation problems... Anybody that tells you they put 92 in their quad and felt a power difference, is either lying, or they think there is a difference because it is higher octane. It works the opposite. The lower the octane, the quicker it will ignite. Take a can of ether for example. It has an extremely low octane rating. That's why it will burn instanly in any engine.
Race cars run on race fuel (usually 100 or higher) because engine damage will occur if they are run on pump gas. It ignites to early, the explosion is trying to push the piston down, while the crank is still trying to push it up. It will literally beat an engine to death. Of course, the easiest thing is for you to try it both ways and see for yourself. Good Luck.

 

Then why with higher compression you are supposed to run higher octane i run VP race gas in mine sometimes and you can tell the difference,but as you said it could just all be in my head. I just dont understand what ur saying

 

Higher octane fuel certainly does burn slower, and hence, does help against pre-ignition and detonation(pinging).

However, with higher octane, you can advance the ignition timing higher, creating more power overall, and better fuel economy.

Unfortuntely quads don't have ping sensors that allow timing to advance to the max and then back off, delivering optimal performance.

For myself, I will probably keep using the higher octane. If my quad is under a lot of stress, i prefer it not to ping and put a hole in the piston.

 

Advancing the timing, does not always increase
performance. There is a power curve, it will max out and then start descending. I don't think these guys are adjusting the timing, when they put higher octane in them. Just trying to help them understand that it isn't helping anything.
I'm not sure how you "stress" your quad, but if it is stock, then it was built to run on 87, and it will be next to impossible to make it spark knock. If you have increased compression and replaced the cam, and so on, then it is possible.
Even if you run high octane, and bump the timing up, if you took it to a drag strip, and ran a before and after test, you'd be lucky to see a difference of hundreths of a second.

At any rate, I have no desire to offend anybody or start an argument. I was simply trying to help the guys that don't understand the purpose of higher octane fuel.. I hear all the time that it makes more power and burns cleaner, and so on. Just trying to slow down a common misconception.

 

Thanks guys. I will run what I have(87 octane) until I get crazy and mod my engine.
