Ezy10z Posted on Jun 23 2004, 03:04 PM I'm not 100% sure but I believe I read a post about the Nizpro T having a rev limit of 7500rpm ??? yeah I think it did and probably had a fair amount of pressure forced down it's neck. I think that if have decent internals, correct tuning and remember why engines with long strokes don't last. then monitoring the situation and should be fine and it should handle 7500 reasonbly well. any engine can break any time and usually turns to poo anyway. and most of the reasons why you get a rod out the side is not the rods fault anyway.
