530grafix Posted July 7, 2007 Report Share Posted July 7, 2007 Question is, does it make much difference when you port your cases to match the porting of the cylinders? thanks for any help Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted July 7, 2007 Report Share Posted July 7, 2007 I noticed a difference. Quote Link to comment Share on other sites More sharing options...
alcoholbanshee Posted July 7, 2007 Report Share Posted July 7, 2007 From the dyno tests I have seen it makes little difference at all. Certainly not noticable. It is really one of the piece of the puzzle kind of deals. Once you get all the peices together you have a complete package. Usually like 1-2hp on 100+ hp engine.

It seemed to me like the midrange had more pep after I had it done. Quote Link to comment Share on other sites More sharing options...
Fireroad Express Posted July 9, 2007 Report Share Posted July 9, 2007 (edited) the larger i went in displacement(bore size) the more concerned i'd be with case porting. for a stock bore shee motor, i wouldn't even bother. at 68mm i'd start to consider getting my cases ported. especially with a dune/drag port. if your sinking big bucks into a 10mm engine or larger,i wouldn't bother running it unless it was case ported. but hey, thats just me.

locogato11283 Posted July 9, 2007 Report Share Posted July 9, 2007 id say every little bit counts.. i mean for what it costs, if you get 1 or 2 hp youre prolly doing pretty well.. i have it done on my 10mm cub motor... but shit after spending so much on it, it doesnt make sense to not go ahead and have it matched.. if youre just stock stroke, stock cylinder wity no porting i wouldnt bother. its not worth the hassle.
