Nitrous on a leafblower

[tonydanzah]

Found this video i took a few years ago. Myself and 2 friends from tech school found a leafblower in trashcan next door on garbage night. Ran pretty aweful even with some turning. So we stripped it and ran nitous on it hoping to blow it up. It took everything we gave it. After it was all done it ran like brand new. Probably burned out all the carbon and reseated the piston.

I'll post one video now and the other if more interest.


not sure how to embed the video



DO NOT TRY THIS AT HOME.

You have to add fuel too, otherwise all it is doing is making it go lean. Nitrous is an oxidizer. When you add more oxygen you also have to add more fuel or it just leans it out (wich is a bad bad thing). When you install a dry kit to a fuel injected car. You add only nitrous and the computer on the car adds the fuel. The leaf blower has no computer, it is carbureted. With a wet system you add both fuel and nitrous.

Thanks but, i know how a wet and dry nitrous system works. But leaning the **** out of this thing did nothing to hurt it. It was a trashcan leaf blower. The nitrous did affect it, remember lean is mean. Even though it wasn't getting the proper amount of fuel, it was still able to hit much higher rpms with the nitrous than without.

It was probably lean, hot, and auto igniting. With no fan load on there it would rev itself too the moon, even without nitrous. But generally the ignition module has a rev limiter around 9-10K rpm. Get it to auto ignite and they'll go sky high. I've delt this on a simular engine model, would stop reving at 9400 rpm despite no load,because the rev limit program was coming into play. A strange issue allowed it to auto ignite at times, and would run off to 14,000+ rpm, even with the spark plug boot pulled off.

Lean is mean, till the piston melts.

not sure if it had an ignition module, heat wasn't really an issue as if would after long runs stall and spray nitrous out the intake and exhaust. Or it would get to the verge of stalling then we would back off the nitrous and it would pick back up again.

Tony D you should not have posted this thread. Now there will be members thinking about trying to soup up their rider lawnmowers this summer.

At the very least you should have placed a disclaimer. "OLD PEOPLE DO NOT TRY THIS AT HOME."

fixed for you

If it had no ignition module, what was hooked to the spark plug to make it fire?

a magneto?

Why does everyone have to be hating? Why can't we just enjoy a little entertainment and move on instead of always having to nit pick everything. Who cares how he had the nitrous hooked up or what he was doing was dangerous, it was done, can't change it now and it had entertainment value, move on already!!

Nice video, I'm out!!

Tim Allen would be proud..lol!

I wasn't trying to hate on him, and I apologize if it came off that way. I was just offering an exlination as to why the revs climbed so high.
