My uncle used to run his cars at 40%, he knows alot about them and he was telling me about how hed be running them and all of a sudden it would just seize up, im just wondering if anyone else uses ***ROCKET FUEL***

lol

Thanks

I never ran more than 30% in a car but I used to run 65% in the boat. It hauled.....

rofl, unless u want to be pullling new engines out your *** then stick with someone below 30%

My son doesn't use any nitro and his car is as fast, or faster, than the others using nitro. It really shows on the drag race up the main straight .

no nitro? what fuel is that? pure methanol??

40% is a little extreme for a land vehicle, 30% should be more than enough power for any land vehicle, and no nitro fuel is called FAI fuel, very popular in Europe, i think the planes over there run a very simple 80% methanol 20% castor and they are among the highest performing plane engines, simlpicity is key

Very often used in airplanes. I have a friend who uses no nitro on a plane. Someone told me that cars can't be run without nitro (I never understood why airplanes could and cars couldn't), I guess he was wrong...

I use no nitro fuel in my planes. I have tried it in my heli but it would not idle properly (about 15% is ideal). Different engines are designed for different % nitro content. Some engines wont run properly without it and some wont run properly with it.

40% is a bit of nitro to be running. You would have to add a couple of shims to do that, or you would just get predetonation I would think. And the engine wouldnt run all that well with predetonation, and if it did run as harawong said unless you have the capabilities of pulling engine's out your @$$ then I wouldnt do it.

But if you can pull them out, I'm wondering if you can get me a new .18cvr or maybe a .12tz. But getting back to all seriousness, I wouldnt do it, as I have run 30% and that had plenaty enough power and it also kinda tends to kill the engine a little faster, I cant imagine how fast 40% would kill a engine.

As for the no nitro you can run engine's on no nitro, as for a car running no nitro keeping up with a car with nitro. I'm not saying that it's impossible but two of the same cars one using and the other not using, I would put my money on the car thats using nitro. I know the difference, from switching 20% to 30% and there is a big power difference. But I always wanted to try running with no nitro as I can get all the methanol alcohol that I ever want. Maybe someday I will get around to trying it.

You can run without nitro no problems. Run a higher compression ratio and it's going to work fine.

The engine we run on zero nitro is a Mach 28 in a Hyper 7. It ran fine completely standard but I've done a fair bit of playing around experimenting with plane engines so we modified the engine to a much higher compression. That's when it started running with and beating other Hyper 7's. We also use 20% castor so it's a true FAI fuel. It certainly couldn't be as fast as a car with high nitro but at the level he's racing right now it's more than adequate, not to mention cheaper and runs for longer on the tank .

wow this is great stuff, i heard that no % nitro in fuel, the fuel is called castor straight, thats just what i heard maybe its and english term like, MINT, lol (only a certain individual will know what i mean) QUALITY

fit eds, (there is a long list lol)

Thanks for the results
