Sirio engines thread
Discuss Sirio engines here. :cool:

Yes,that way we don't have a hundred different threads opened which are all discussing different issues with a certain engine.It's maybe best to try to keep most of the info on a particular brand engine in one thread so it can also be used as a refernece and all the info grouped. :cool:

if your engine has a std. plug (non-turbo) use Novarossi C7S or C8S, if your engine has turbo plug use Sirio S001720127. These engines love cold plugs. AFM Fuzzclub If you are buying the Sirio .12 engine, get yourself the "new" Sirio Evo2, it is a rocket, I have one and it has an awesome high end. Following is a report on the new SIRIO S12-TRP EVO 2, and it's comparison to the old. I only could get the text of my word document, because i don't know how to post an attachment with pictures, sorry. AFM "This new engine is in conformity with the 2004 regulations It is an evolution of the Sirio 12 TRP which was the first production Sirio . Having used the old 12TRP, I will benefit from it, to compare the 2 engines and to see thus what evolved. With the first glance, what one notices is the cylinder head which is larger, of blue color and the Sirio initials are engraved above with the name of the engine EVO 2. The carburetor is not any more with 2 adjustment needles as on the last TRP but with 3 adjustment needles.It is new and resembles much the one equipping the .21 Sirio Kanaï. Much more material around recovery screw (mid range needle), it is in this place that Sirio had problems with sealing in the past. Still a common point with the Kanaï, the casing evolves and integrates now an “O” ring to improve the sealing with the carburetor, moreover the mating plane is more significant. That should ensure a perfect sealing. The casing is equipped with new high speed bearings, which is too often neglected in this category of engine. The front bearing is a new more resistant model. As his big brother.21, the casing of the .12 is worked from origin with cuts at the bottom of the boost transfer and at the top of the exhaust transfer. The crankshaft has now more work in observance of the new regulations. The skirt is worked with beveled cuts on the side transfers .The exhaust transfer is modified at the top sides to match the cuts on the casing. The piston is machined and not molded.That ensures much better thermal and mechanical qualities.The rod is of the knife type with a central groove and 2 bronze rings equipped with holes for lubrication. The back plate is equipped with 2 "ears" in order to aid the side transfers. The S12 TRP EVO 2 is delivered from origin with a turbo insert. This insert is very thick and deeply fits in to the cylinder head in order to support heat exchange and to thus ensure an optimum cooling. The engine has 1.5 hp and 41,000 rpm, with a more progressive power band and a killer high end." |

Not to contradict you, but I have the "new" SIRIO S12 TRP EVO2 and the carburator works perfectly, it seems the problems are a thing of the past, I even tried the engine with a Nova carb just for performance comparison and didn't get any difference. The engine works fine with both. Ceck my previous post on a report on the new engine. AFM |

Where's the best place to get the new SIRIO S12 TRP EVO2? ..
|
I got mine in Spain, at www.azormodelismo.com. Cost me 237.00 Euros.
Also i've seen it advertised at Kyosho-France, and in the USA Trinity is announcing it for 2004, but it isn't for sale yet. Hope this info helps. AFM |
I'm awaiting the arrival of my Sirio .12 TRP (black head) and I was wondering what plug I should start with? I plan to run Trinity Platinum blend 30%.
If you can, offer up a plug and what temp it is, and if possible, comparible plugs in alternate brands. Thanks |
Plugs,plugs.OK:
For non-turbo head (std. plug): Novarossi C6S mediumplug, for cool days Novarossi C7S cold plug, sunny and hot conditions Novarossi C8S verycold plug, for extremely hot days or high RPM running. For Turbo head engines: Novarossi C6TGF hot plug, for cool days Novarossi C7TGF medium plug, best all round plug for most conditions Novarossi C8TGF cold plug, for extremely hot days or high RPM running. Don't have experience with other brands, sorry. AFM |
