I have showed you a couple places where they state the facts so far all you have done is run off your key board and called me names .So who actually is the ignorant one here .
Show some documentation by some real people.

[ No, that was you with your 'I feel why prematurely wear out a $ 3-500 engine when I don't really need the extra HP.' comment. ]



This one cuts the cake ,you don't think adding extra strain and cylinder pressures of 30% nitro is not going to hurt your engines? plus the fact your swinging a larger prop than is more than likely recommended,Another extra strain bonus and yet you have the nerve to set there and say your engine will out last one thats been properly taken care of.

And I also agree with Rcpilet get a bigger engine if you need that much power !
And as far as me knowing a little about engines ,Owner and operator of a Automotive Machine shop for 30 yrs I think qualifies me as knowing some .

Ok I give oh mighty know it all Engine God ! Were all wrong and your right .
There ya happy !!!!!!!!
