Sirio XXXV .12
 

Hello guys,

just wanted to open this thread in order to share opinions on XXXV .12 engines from Sirio ...

cya !

Great! Was thinking to buy that engine for next season!

first we must see what diff it has from the previous xxx model.only a diff case?does it make that noticed diff that make us buy it than the older and less expensive model?

Rock solid engine durable con rod and incredible speed! But the cuberator is pc of sxxx~

Carburator ? ... so you are using a non-sirio one ?

The new crankcase is stiffer than the old one and has a slightly smaller volume = faster gas movement and higher internal pressure.

Awesome engine, IMO the best .12 out there and I also never had any probs with the carbs.

Nova carbs do fit though.

I'm looking to buy the new XXXV. I'm wondering if there are any performances differences between the Sirio 2611 and 2653 pipe? Also I want to buy an extra con rod with the motor. Are the XXX piston sleeve and rod the same as the XXXV set? Thanks in advance.

Is this the engine you guys are talking about?

Yes this one.

xxxv
 

that looks like the older one xxx not the xxxv but the older one was a very good motor also and that not bad price with the pipe.

Might just be an old picture. I thought the XXXVK is the latest sirio sedan engine.

after Picco made Torque for 2011, Sirio is probably the last one great cheap engine on the market now.

xxxvk
 

yes that must be old picture but they had vk seperate from the xxx it is very fast motor unfortunately my carb slip out in a race and wore my piston out my bad must not have tighten it enough

yes, i hope sirio out with new model this year. already using sirio xxx & xxxvk around 3 year. cheap engine with great power & fuel consumtion. last 2 race i tried novarossi, i give me headache about fuel. now come back to sirio.

there is already a new model that is called xxx nemesis.

i have already seen that motor on many different sites but not in the original site of Sirio Engines...:( Whats going on with this motor? Its original or jut a tune of XXX by others who named it SIRIO XXX NEMESIS....??

this crankcase is like the xxxv,not the xxx.and i think that since the new orion abi is based in the xxx and not the xxxv noone else could take the xxxv platform.

Sirio xxx Nemesis
 

Hi

I've seen that the bore and stroke measurement of the xxx Nemesis Engine are the same, 13.9 x 13.9!
Can someone tell me what this mean reguarding the power band of this engine?
Has this engine more bottom end or top end power?
Ohter engines like Nova, RB, Max have the long stroke version 13.8 x 14.2 and Picco, REDS,... the short stroke like 13.7 x 14.0.

It will have more HP than torque since it has a 'square' bore/stroke, but where it will all be focused really depends on crank timing and how the ports are designed.

Where can I find XXX Nemesis and parts?
Even sirio official web site still stop update in 2010.

Got 2nd place on Chilean nats last sunday, my car is the yellow/green, im using Sirio XXXV .12 + VP PRO Fat/short pipe :
