R/C Tech Forums - Sirio engines thread

If you are taking about the Sirio Evo 4, I do have one and like the XXX better. If you are talking about the IDM Evo 4, I just ordered one a few mins ago and should have it here in about a week. I want to give it a try at the Motonica Grand Prix which is in about 3 weeks.

no i was talking about tha sirio.
But let us know about that new baby IDM Evo 4:nod:!

I was looking into buying a sirio S21-CL7 R STI how would you compare this engine from IDM.21 novarossi 359 tuned and all the other engines.

I have seen thsese engines run at my track and the idm .21 will have a little more bottomend, the 359 tuned will be the better all around engine in terms of performance and reliabilty. However the siro is a great engine and has a ton of top end speed thats what they are none for there revs. Just make sure that you dont over heat the sirio because it has an AAc piston&sleeve which can be ruined if they are overheated. But if you want sirio top end and novarossi durabilty get the jp r9.:) But the siro is a great buy you wont lack any power.

this engine is insane, 2 guys are running them at my local track. TONS of power!! I don't think you'd be disappointed if you go with it. best with 2013 pipe set.
