How can I get a little more power for cheap.
I only have 3 races left and one is a 100 laper and I need a little more power I am fast enough to keep up but not quite fast enough to make very many passes.

The cheapest way to go faster is to work on set-up. If your keeping up now you may just need to make better use of what you have available. Remember, more speed through the turns gets you to the next one faster.

do you have a fuel specification? does it say no additives? have you ever heard of nitro propane? it's an additive that, with proper jetting, will make a little more power. most tracks don't check your fuel because it's too technical of an issue for them. i read an article on it in circle track magazine a year or so ago. you'll have to fatten up the jetting a bit. just a thought.

Can you enlighten the UN-elightend or is it a secret.

Maybe just a little secret. Propylene oxide is an oxygen bearing fuel additive that from what I have heard, takes some pretty sophisticated techniques to find it if done right. I beleive that this is what some big time guys were soaking their air cleaner elements in a few years back. You get a boost for qualifying, and its gone when you pull in. It allows you to back off the timing of the engine a whole bunch, and still maintain a good burn. Any time the fire is lit and the pressure in the chamber rises before the piston reaches TDC, its taking away power. This is called negative torque. So, if you can light the fire later, and get a quicker controlled pressure rise, negative torque is less, and more goes to the flywheel. Mix at up to 5% by volume, and VP Fuels sells it.. no, I did not say that. Although it is one of the safer additives, if you play with it, you better know how to read a plug for impending detonation with the best of them, and have a deep pocketbook, just in case. How much do you back the timing off? Well...uh yeah, uh..every engine is different, yeah.

If i remember right there was a formula on here that gave the amout of jet you would have to increase to mix nitro with fuel. Try to do a search on nitro ...that should bring it up. Let us know how it works....might want to put a scattershield around the motor he he jus kidding.

You dont have to cheat to go faster !
Would you actually feel better doing better by cheating, Find that perfect setup and cam and you'll be all set.

you better jet it up a bunch unless you're wanting to change motors anyway from what i've read almost alcohol jet sizes and you need to drain it the next day to keep it from corroding the fuel system & leaving junk behind just a pain in the @ss if u ask me.
