Just trying to figure out if i can convert a mini moto engine to run on R/C car fule. A 2.5cc engine runing on 25% mix will produce 2.8hp, What will a 49cc be like?! The only thing i see that differs from the R/C car engine is that it has a glow plug, and the moto has a spark plug, Its just for a cheap laugh but any info would be good! thank you

Nitro needs to run about 30 to 40% richer and the glow fuel already has oil mixed in so you will have to either empty the oil or not mix any more in, but that's about it. It will run, but you'll get more power by using a bigger jet in the carb.
Not sure you will see any advantage though, nitro only really comes into its own when it's compressed massively. Nitro glow plug engines use 30:1 compression and on a bigger scale use superchargers to force a lot more mixture in. Mini moto engines are around 10:1 so I don't know if you'll see the full advantage of using nitro. The higher the compression, the more nitro you use, but obviously the more dangerous it becomes too!

thevert in da house: Just trying to figure out if i can convert a mini moto engine to run on R/C car fuleOne word, DON'T!!!! We have had a buch of people playing around with this and if it's one of those Chinese "cheapie" MiniMotos they will blow up in your face, it's almost impossible to get the compression up to the level you need to get it to work and if you do the quality of that "China-junk" will just fall to pieces.... If you want to go monster power go for NOS-Holley's Nitrous-kit for GoPeds, I have fitted that to a Piaggio Ciao with a Polini EVO motor in and it takes of like crazy and can be controlled with regards to the Nitrous, it can be setup to work real good. This is the system I use www.holley.com/products.asp?product=03200-OZNOS it has a fuel pump that runs on a 9.5Volt battery so you don't need an 12 volt electrical system.... DP says: To get it working 100% it has cost me 2 motors and they are €xpensive....

thevert in da house: good idea, Already got a nos for it. heheWhat ever you do DON'T use NOS if you are going to try out RC Fuel that spells dissatser!!!!! Belive me I have been using NOS in cars and on bikes since the early 80's, was the first in Sweden to street race a car with NOS and since that I have had NOS fitted on salt flat racers as well as street race cars & bikes, I have even had NOS on two daily drivers one 90 Acura Integra and one El Camino SS454. With the right setup NOS is a bunch of fun and will not (as most "know-it-all" claim) kill a motor in a day or two, right now I'm building a Stripper from a Aprilia RSV Mille, the bike will be used strictly for fun and as one of the first and only (except a new chip and filters) motor modifications is a NOS setup..... If you want to learn more about running NOS buy "The NOS Bible" How to install and use Nitrous Oxide by Joe Pettitt, I must have worn out atleast 6 copies of the book....

i'v got 2 spare motors, could be worth finding out if it will work on these motors then go on to the water cooled versions

I would. Where's the fun in not doing it?!!! I put nitrous on my 125 just to 'see' what it did. It scared me, that's what it did, but if it blew up then so what? I can fix it. I like the idea of using a nitro rich fuel and nitrous, it spells to me that you can use a lot more nitrous as the nitro won't detonate anywhere near as easily as a petrol-only fuel. Shame my 125 is a 4-stroke or I'd give it a go on that too.

i always thought nitro was closer to diesel than petrol because of the glow plug???
