Passion 12 port- dyno #s please post!

[Fireroad Express]

been hoarding parts like crazy for the last 2 months(carbs,reeds,+4mm crank,adjustable timing plate,head and pipes) getting ready for an engine build. looking seriously at the passion 12 port jugs to top off my cases. what kind of h.p. #s are you guys getting out of this engine with a +4mm long rod crank and stock bore. i realize hp #s on paper don't matter as long as it goes like a raped ape but i'd like to know the potential of this set up. will be using pump gas and 35mm carbs. looking to build a very hot open-trail/fireroad machine. if possible i'd like to see some dyno pulls.please post some #s. thanks in advance! oh yah, thanks to everybody who helped me out with the parts. :thumb:

jim at passion is currently building me a 4mm 12port, with bigger carbs, head, custom domes, adjust timing plate, bigger bore, and the works with toomey t-5s, and he said when he was done the motor should make 75hp at the back tires on race gas. approx 90hp at the crank. hope that give you some sort of idea.

I'll be getting mine on the dyno maybe around mid july sometime. I'll post it when I get it done. I'm still breaking it in and jetting right now.
