Nitro Motors

Not a lot of us run nitro, or at least the guys that run nitro arent here browsing the forum. I'll try my best to get as many racers as possible from hals to join this forum, so they can be in touch with the El Paso RC community.

Well, for who ever runs nitro, i have a couple of tips that you need to know about nitro motors. Just like eletric motors, there are temps to follow.

First, a nitro motor should be running in the range of 180*F to 240*F
You can go as high as 250*F in times, but once you pass that mark, you are in problems. No motor should be ran at more than 250.
I would say that the perfect temp for a motor is somewhere in the range of 210*F to 230*F
Also, as per other articles based of off pro drivers, the perfect temp where a motor gives out its better performance, is 220*F.
I wouldnt really recommend running a motor at less than 180*F since it is actually hurting it because its not hot enough to let all the parts move freely. Once you pass 180*F thats when the motor has the best lubrication out of the nitro gas and thats when the metal parts inside the motor has less friction.

Well, as for tuning, ill look for some videos for tuning, because it is actually a little bit complicated to explain it.

But hopefully a gave some tips for the temps of the motor, which i would say is one of the most important thing that you need to know in nitro motors.

And trust me, you do want to follow this guide lines, because you will either end up with a worn out uncopressed motor or a broken motor.

If you have any questions, go ahead and post them, so we can discuss them, and im sure Hector can also help us with this info.

And Hector, if im wrong on something, please let me know so that i can go ahead and correct it.

That's some great info Alex Alex what should a buyer looking at a used nitro look out for?

check compression, thats the first thing you need to see on a motor, and it would be good to ask how many gallons there is on the motor. Also, you need to see the condition of the motor itself. You can clearly see scratches on the head when it has a lot of use.

Also a good investment is a engine heater! http://www.competitionheat.com/Home_Page.html .. You need to tune your engine when your chassis and engine are fully heated. I see some people tuning right when they start there buggies up. You need to run the buggy for atleast 3 minutes before starting to adjust anything. Also adjust the engine with the body on the car. Also old school method of testing if your engines heat is by getting dab of spit on the top of the engine it should take 4-5 seconds to boil off. On the low end get a pair of pliers and squeeze the fuel line tube it should take 4-5 seconds to cutout any faster your to lean.

When you hear people say the engine needs a pinch that usually means its on its last leg.

+1 on the comp heater, Eric has proven its value of preheating an engine and it truly works. When tuning follow your engine break in guide from the manufacturer then head to the track for final adjustments. It's always good to tune the high end first, then move to the low end paying special attention to your exhaust smoke (plenty of smoke equals good lubrication and a richer fuel setting). When you adjust to a point that your motor is running with an extremely high pitch with no smoke, you're at a lean setting and will need to be richened to ensure not to cause damage to your engine. At a lean meeting you'll also see an unreasonably high temp for your engine make/model.
Great thread started here and hope its helpful to all.

you can pick up a heat gun for around 15 bucks it works almost as good but you need to consitantley check the temp and get the motor around 180 before starting it but take your time warming it to that temp and also to help preserve your motors you will want to alwaysput the engine at bottom dead center as soon as you are done running it. also at the end of the day pull your glow plug and put a little bit of oil in the hole little things like that will help your engine last

The audio isn't the greatest, but Tebo really helped me out with these vid's. Pass it on, knowledge is power. Old Pic of Tebo (O'Donnell days) and Hoosier (Mugen Days lol). But, these tuning vids are VERY VERY helpful.
