anyone have any experience or opinions on sirios .27 monster block race engine?

i guess its not that polular lol i will let eveyone know how it performs when i get it broke in

Ata thrash had one in his mugen

Seemed pretty powerfull when I saw thrash racing. I've heard people complain about pullstart probs and finicky tune but if you can tune there shouldn't be a problem

its a race only version no pullstart just bump, came that way in box.

cool, one less headache then

Overall from what I saw, the motor was powerfull and ran pretty well.
