New SIRIO S12 TRP EVO 2
Guys check out the following link from Kyosho France, they are the pictures of the new War Horse from Sirio. They've surely improved this engine...1.5 hp and 41,000 rpm. I got myself one from Spain. The engine is impresive, new carburator, machined piston,and high quality work all over. Now lets see how it does on the track.

It's a good motor. The one in the pictures is the IFMAR legal engine. The ones in the states have a better crank than what is in the pictures, and they have an aluminum sleeve. I have modified quite a few of the new Sirio's and have heard nothing but good things.

is it the same with the sirio aac?

Grinder, thanks, I new you would post your experienced comments. Perhaps you can help me with the issue of running in time, in the instructions it states a 15 minute running in time, doesn't it sound to little time? or is the engine loose from origin. What is your advice on this issue?. Also it states not to use higher than 15% nitro????. What head clearance would you suggest for 20 - 25 % nitro?, and what plug to use with non-turbo head. I usually break in my engines on the Serpent bench at the richest 2 stroke setting possible in order to avoid premature damage to the conrod with 4 stroking, is this correct?
And what pipe do you suggest to use with this engine.
I hope i'm not asking to much.

Sirio's stated time of 15 mins is a bit short, I run my sirios for about 30-40 mins on the track gradually leaning them down and they are fast
I'm not sure about running them on a bench first, I've had engines done like that before and they're ok, but they still need to be run in under load on the track.

Where can this engine be purchased from? Its a good looking engine... how much does this cost compared to other engine manufacturers?

In the USA I would contact Uriah Murnan. He has a lot of experience with modified SIRIOS, and very affordable prices.
Check his last post here in this subject, he is known as GRINDER, and has a web page for Murnan Modified Engines.
If you want stock Sirios, Trinity is the distributor for USA.
Hope it helps.

Thanks Grinder
BREAK IN: I actually do like 3 bench tanks(bigger), 1 at idle(heat cycling) and 2 at WOT, and then finish with 2 to 3 tanks at the track. I get better life span on my conrods that way.
PIPE:I finally decided on getting Sirio's own pipe, it is an In-Line pipe and the guys in Europe say it is the best pipe for it, very smooth from low to high end with lots of mid power. The pipe is Sirio S12 200006, and i don't think it is available in the USA. I will post results after it arrives and have tried it.
GLOW PLUGS: What is the equivalent in Nova Plugs to those O'Donell's????, because Nova's are about the only thing available down here.
By the way, I tried the New Sirio carburator on my old Nova Mega and it worked perfectly and had no problems to tune it, so old carb comments about being bad, are past history.

Hey Grinder, do you know the size of the pin for the con rod on the crank? This is on the Sirio.

Thanks, I ran it some Sunday, and after tuning it was great!
What about the tolerances? How small is too small?

It's tough to beat the Murnan NS12. I have yet to see an engine that could keep up.
