and that's on dirt, in road racing the 125s are more like 54hp
But being realistic, 100hp/L can be had with old school calculations on graph paper, and/or careful selection of components that work well together.
on my lambretta build I'm aiming for 150hp/L (~26HP from 175cc) at 8000 rpm. First time using EndMod 2T and getting all the measurements right has been a bit of a learning curve, and the simulations are up to ~25hp so far. finally feels like a science (with a bit of art).
speaking of realistic goals:

The reduced lifespan of a hot motor is something that I fully expect. I get about 12-18 months out of a tuned motor if I'm lucky. In this case, the failure was just a little more dramatic than I was expecting.
For modeling, do you have a link to information about Endmod? That sounds pretty interesting, but a quick google didn't point it out, only lots of other stuff that was not a motor design & simulation tool.
$400 US so not to be sneezed at!
Chandlerman, have you seen this guy's work? Quite interesting - in regard to max power from the 150 case motors. Especially the case work on the LML. https://www.facebook.com/Stratocaster99/
