OS TR engine thread
 

I wanted to find out more about this engine and i am planning to buy one.

Please share your experiences with it and it's advantages/disadvantages

And the TR-T too

:nod: You should contact Atomic at www.kinetixrc.com
He ran this engine at the SWCS #3, He TQ'd and won the sedan class w/ it! :nod:

TR
 

how is it going compaq? I do not own a OS tr, however I do own a CV-R and I have come to find that the cv-r has good low end power but lacks the top end. I have also read thouht some of the post in other threads, and others have mentioned that the Tr has the same probelms, it is better orientated for small to medium size tracks.

thanks Jason

I have also heard that the TR lacks in the high end department. But it's fuel economy is a lot better than novarossi and RB and etc., is that true?

I've been hearing that a new version of the TR is coming out, is this just rumors or for real?

Here you can find info on the new OS TR-R

They say it is allready beeing sold in Europe and it has same lots of torque and now same top end as most italian engines, but with reliability and fuel economy as traditional OS engines.

i see that it uses lots of silicon on it's piston, which is bad for reliability, but since the pistons are good for 5-7 gallons then i think it might last.

I know the regular TR costs $130 and the turbo version $160. Any guess on the price of this new TR R-Spec Competition Engine??

From where this statment come from?:weird:
More Silicon longer life of engine, more silicon more stable geometry, more silicon better expention rate-everything is more-only one thing is realy difficult-to put more Silicon to Al alloy and have piston not bridal ( too much silicon piston brake so easy). A lot of developments was done to find right alloy with great ammount of SI and keep very strong.
BTW, OS pistons doesn't contain that much Silicone as others.

i'm just saying too much silicon is bad. I know it reduces weight and makes the engine have less friction but it makes the piston weak.

Well I disagree with you, more Silicon is better ( but can't tel you what is reasonble limit). About weakness of the piston-yes in many cases it is getting weak after Si content is more then 24%, but again there is way and recepies to make Si content 27% and still keep it strong enough to don't brake or explode.
I would love to have 32 % but at this point i just have 27%
We have Al alloy with 32% Si, but it has other properties which doesn't suit to our needs, so for now we stay with 27%

Can anybody tell me where i can find the best deal on the TR or TR turbo??

so far i see that the TR costs $130 and the TR turbo costs $160. Anybody know better deals, and where?

I see you are from Socal. I just bought one from Tony's hobbies in La puente yesterday for $118. That price was for the standard non turbo

website, or phone number???

Hello, Ron Atomic is running the .12TR-R-Spec. This engine was designed for large tracks. It comes with the new Hyper head and P6 Turbo plug. the crank has been modifiyed for more Horsepower. Ron will be using this engine at the Notionals in Toledo in a few months and you will be suprised to see some top drivers using this engine this year.:cool:

Any idea when will it be available on the market for any mortal???
Do you have any idea of pricing???
Is it true it's allready being sold in Europe???

Seems to me that you work for Great Planes or have inside contact to know all this info.

Ive seen Ron's O.S. engine firsthand , you wouldnt believe it was an O.S. , definitely underated motors.
