i'll mention it

rossi 105 and hurricane.

rossi 105 and OS91 have completely different power curves and hence the OS91 outclasses the rossi at lower revs..
whack an OS optimised fan on the rossi and it wont rev up anywhere near it's claimed max output...

now- pure speculation and based on the claimed specs of rossi- put a hurricane on it so that it doesnt load the engine up at the lower revs and you'll have the best of class at 28-30k revs... 14+ lb thrust.

how 'bout them apples?

i cant help myself about this rossi thing....
