ok heres a question ,
i am wondering what percent nitro fuel to use for my new xtm monster mt with the .28 in it.

one shop i go to sells 20% another shop sells 30%

would i see any increase in power with the 30% ?

20% is better for break in.

Yes but increase in nitro equals increase in temp. Nitromethane creates oxygen when it burns which effectively turns your engine into a supercharger but the more air/oxygen, the leaner the engine becomes and the more heat is created. Stick with 20% unless your racing.

when are we going to hear how it runs, the 28 in there is a good motor i have it in my lst2 and its a animal. i know they up the spurs on it to steel but ....how is it i am dieing to see, the thing is huge from what i have seen probably as big as my nemesis.

Stick with 20% it will produce a little less power then the 30% but it will cause less engine wear if all your doing is running around for fun. If you are going to be racing it a lot then you want the 30% as it will be faster for the track.
