Does anyone know the web site for Sirio motors.

http://www.star-motor.com/

For the presentation of the new SIRIO S12TRP EVO2 go to the following web page http://www205.pair.com/kyosho1/kweb/ (it is Kyosho France) under Moteurs, it is a comparison with the old engine, it is in French but you can tarnslate the page with altavista transalator
The official Sirio site is not up to date.
In the Trinity web page they are announcing it for 2004 and has some specs on it.
I think it is being sold in europe only up to date, I got mine in Spain at www. azormodelismo.com.
IT IS AWESOME.

I have Murnan Modified Sirio EvoII's for sale. $230.00 + shipping. They come with the new carberetor and aluminum sleeve. 3 port turbo. They are extremely fast.

I recently bought a Sirio .15 outlaw 5 port and I'm not impressed at all.I hope the .12 are better.My Mugen MT 12 will spank it.

I just got my Sirio! woohoo!

One quesiton....

I got the 12TRP with the blue heatsink head. What, if anything is different from the original black head 12TRP?

Did you get the new S12TRP EVO 2??? or is it just TRP, is it with 3 needle carb or 2?? does it have ABC or AAC sleeve???

Some TRP's came with blue or black head. The new EVO 2 comes with either blue or black but is larger in Diameter than teh old one. You should dissasemble the engine and check the interior parts and compare with the follwing:

Well what I ordered was just the TRP. It has a 3 needle carb and a the blue head seems quite large. It also has an o-ring to help with the carb sealing to the case. Thats about all that I can spot from the outside of the engine.

I have the S12-TUP Pro blue heatsink, 5Port AAC, 3 needle carb and also the O ring at the carb neck. Dunno whether this is from the newer batch. So far the engine is running very good, no tuning problems what so ever.. and is one hell of an engine!! Is the new Evo2 better than this?

As i said before, go to the following link and compare.

I looked on the trinity site and compared them. One thing I noticed is that they say it comes with both the standard and turbo plug head buttons. Mine didn't come with both, so I'm not sure which engine I have. everything else was the same.

still choosing what to buy between these two 5 port engines.
please let me know which is better overall. i prefer high torque and top speed as well as easy to tune. from some drivers from our race track, i heard AAC is a bit hard to tune than the ABC.

Then your engine is an OS instead. The ease of adjustment doesn't changes with the material of the sleeve, some engines are a bitch to tune and anothers are sweet to do, is a matter of luck. Anyway, choose whatever you want.

Seems that the AAC is more 'exotic' and here, at least, for the same timing wise, AAC P/S is more expensive than the 'ole' ABC... probably Grinder can shed more light about this, he makes magic daily with those engines.

hi Corse-R,
good to hear from you again, over here the AAC is more expensive than ABC, more popular too. probably because of the alloy p/s and its new.

Hey guys

The ABC is definatly easier to tune, there's not much difference in power between the ABC and AAC. When an AAC is tuned properly it has better top-end and is more fuel efficent than the ABC.
