Does this motor use a standard or turbo plug? The description on Mugen's website, says this uses a standard plug, but it has a turbo head? Doesn't make sense to me. And when I looked at the plug that was given to me by the previous owner, it looks like a standard plug....

Any recommendations on what plug I should use?

Every X12 I have/had used standard plugs. I heard that Mugen had started importing them as turbos, but never saw one. You really don't have a problem as they are not interchangeable. If it has a standard head button, a turbo plug won't even thread in. If it has a turbo button, a standard plug will be too small and not grab the threads. If it had a standard plug in it when you got it, then you can only use standard plugs, unless you remove the head and change the button out for a turbo button.

Thanks for the info Scott.

I baught my murnan modified X12 from uriah and it came with a turbo head button. If you were to go but know it will have a turbo glow plug.

Anyone have a link to pictures differentiating a standard and turbo plug?

www.rcnitro.com/rn/articles/glowplugs.asp

scroll down the page a little and there is a picture of the two types of plugs side by side.

Nitrohouse.com has TURBO Mugen X-12's.

They just got them in stock a few weeks ago, the price also raised.

BTW, I have the engine and it is turbo.

Thanks for the reply guys.

Since my engine uses a standard plug, does it mean the engine isn't turbo? I always thought X12's were turbo.

Any performance difference between the engine I have, and the Mugen X12's that utilize a turbo plug?

I know someone who had both engines on a dyno,

I believe the STD. was 1.52HP and the Turbo was 1.54HP.

The RPMS were probably a little higher too.

Your engine is not turbo.

STD. does have an advantage, it's easier to tune, especially when you race at different tracks.

Thanks Fast.

Oh well.. .2 hp difference. I bet I can make it up with a Murnan mod to it I still love the way this engine revs. Really really really high.

What fuel do you use? Right now, I'm using 20% trinity. I was thinking of going up to 30% because I heard the engine can handle it.

I just one this engine in a raffle. The one with a standard plug. I wanted to know if it is made by NovaRossi for Mugen? I don't know alot about this engine, so any info would be appreciated like personal experience. The spec sheet says 41000rpm with 1.52hp with a part# of 'NS12S3". This is the best nitro engine I have owned and just want some more info on it. I was also thinking of running Byrons 30% nitro in it as well, is this a good choice?

It is made by Novarossi. It is a standard plug version of the NS12S3. No problem running 30% nitro. It is a very good engine.

Thanks Scott.

Would this engine be considered a low, middle or high end engine in the Nova line? Any tuning tips or quirks with the motor?

i would consider it a high end stock novarossi.... i would suggest putting a .1 shim in the engine... what do you say scott?

Are you saying its best to put a shim if we were to use 30%?
