M. collari modified sirio EVO2
sirio S12 WCR EVO2 w/pipe and manifold
werks racing LC12PRO3
anyone who has had experience with these motors i would appreciate your feedback. thanks! 
I have the Lamberto Collari LC12 PRO3E MC, modified by his father Mauro Collari, and I can assure you it's wicked fast.
It has to be faster than the Collari's that Werks is importing, because those are the Standard Collari's, which at 1.6hp must be fast to, but according to them the MC version is about 10% more powerfull, and they will have them in the future.
I haven't seen a Sirio S12 WCR yet, so I can't give an opinion, The only reference is that it is the current World Champion...so get your own conclusion
