|CharlieNJ said: (quoted from post at 17:58:48 11/02/12) Rootsy, you have done a fine job. I am curious as to how that GM breathes, does it really breath through that Mason jar and 2" pipe? Would not want to restrict her and suck the seals in on the blower, talk about running away! Otherwise, that;s a nice tractor.|
Well think of it this way. The stock engine was 248 CID and 4 stroke. The GM is 142 CID and 2 stroke. Thus, equal in volume of air moved per crankshaft revolution (under suction anyway). A two stroke moves twice as much air as a four stroke per cylinder per revolution of the crankshaft. I don't have this engine turning more than rated RPM either. 1520 RPM at WOT. Even though it is pressurized it isn't a whole lot of pressure.
At one time or another someone puked this motor and put it back together. It has a different supercharger (was painted alpine green) and a Reliabilt rod (DD reman) in one hole.. Had two different liners and two different pistons in it. This post was edited by Rootsy at 19:39:49 11/02/12.
