What i heard from my Lhs was that if you purchase a turbo head.. it doesnt really make it a Turbo because you still need the crank to be Turbo.. i dont know about that but you might want to ask Motorman for that advice..

Motorman you can take this.............

well ya you kinda have a half turbo but each component adds its contribution. Personally the crank is more important than the head as (and here we go this is just my opinion) Turbo plugs on a 12 engine provide a dubious contribution to power at best.

15's and 21's are another story

you can get by with stock head clerance on an MT (.018 thousanths) on 30 percent nitro yet above 85 degrees I recommend adding .003 (thats thousanths not MM) to get .021 MM head clearence. This will aid engine cooling.

PS always use a alumunium head shim against the liner if you can get one. If you have to add additional copper shims put them between the alumunium shim and the head button. Keep the alumunium one against the liner. This goes for 21's too

Why? Don't get mad. Not a challenge, just a question for my own education. Thank you Dennis.

Default Adding more power to MT12

Using a turbo head will add a lil bit of power. Try buying a turbo serpent crankshaft it will add a lot of power more torque and your engine will last for 8 to 9 mins running without refueling.

I was always under the impression that by "porting or modifying" you are makeing the engine more fuel hungry.... meaning it will drink more? Is this true?? Or by doing such mods are you creating a better air/fuel mix?

yes porting your engine will be more fuel hungry.... but modifying crankshaft and combustion chamber is a different story. Using a turbo crankshaft and turbo head will create better air/fuel mixture and more torque will occur

Could anybody give me the standard break in needle settings for the MT12? I don't seem to see them anywhere in the manual.

Check the Tech Tips section on Paris Racing's webpage. It's a Novarossi based engine, so use those instructions.
