Which Sirio for RC10GT?

[PiErow]

Which Sirio should I get for my dad's RC10GT racer?

Why sirio??

 

[Diver6127]

because that's what he wants

I like sirio. I want a good high performance racing engine. I was also thinking about the NOVAROSSI's, and RB's. However RB is out. The Sirio seems to do good in the NATS.

Diver you run these little engines which Nova or Sirio.

Sirios have huge problems with air leaks.


I'd look at the OS TZR

I havent heard of any air leak probs with Sirios... They are high class engines, they shouldnt have any probs.

I've never had a problem with mine.. except keeping the front wheels down on the track...
The Sirio .12se is a sweet motor
the track owner has a .12tz .. he can't keep the thing running.. never idles and he knows how to tune a motor with the best of them

I have heard with the sirios its a hit or miss type thing, some leak, some dont.
I though the TZ was for onroad cars?

Sirios have huge problems with air leaks.

You'd be amazed what a little high temp rtv sealant can do!

Pierow, I run nova based engines (Novarossi NS12S3, Mugen X-12, Max12 mod) for my onroads. There's nothing wrong with sirios. They are just known for airleaks around the neck of the carb. I had this prob with my Sirio 21 Kanai Evo2 engine. High temp sealant does the trick.
