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

http://www.radiocontrolzone.com/foru...d.php?t=167310

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.

AFM

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

:D

Yes I work for hobbico, I am the OS engines Product Manager.

Thanks for the info gijoe, can you comment some more on this:

"Yes they have been using this engine in Europe for about 7 months but the engine from Europe is a little different".

What are the main differences from the one for Europe and the one coming to USA. I ask you this because I'm going to Europe this Monday and i planned on buying one over there. Or should I wait for the USA version???

AFM

Wate for the US version. because in Europe their spec are different from our's. Plus you will not have the black crankcase and I think it comes with the sliver Hyper head. ;)

THANKS GIJOE
WHERE AT TOWER'S SITE CAN ONE SEE IT????

I recently got an OS tr-T. I must say this engine is Super tight! I haven't got to leaning it out after break in but it get's moving pretty well even with the needles still rich.

If you can afford it switch to the Hyper Head, it will give you better cooling and you can really lean the engine out without over heating.

The engine has not been posted yet When it is posted I will notify you:D

i ran the old model 12tr or a year and a half and to say i was pleased is an understatement. for short tracks in a ntc3 it's perfect and the typical reliability of OS to boot. i got over 6 galons of fuel through it. i got an sts now and though it is faster, the quality just isn't nearly as good.

Well you will be double pleased with the R-Spec, I think the low end is to much, but the topend is great lots of R's and some left over. I will have a full report of the Texas Biggie next week. I will fill you in on how the new engine is running and if your down their tell Ron Hey!!:)

does tower hobbies sell this Hyper head and how much is it? And this hyper head is for .12 right?

Also i have a question about the warrenty on this engine. I know OS doesn't give a warrenty on this engine but what if it has a defect?

ok i went to tower hobbies and the Hyper head was $33, while the original TR-T head is $51, how come the Hyper head is cheaper since it's so good for the TR-T?

Also tower hobbies had the R-Spec head too, but it didn't show a pic. Would the R-Spec head fit the TR-T and cool better than the original head and the Hyper head?

The Hyper Head turbo comes with the Turbo-button as the regular Hyper Head does not. Yes you can use the R-Spec head it will fit but if you going to use Turbo Plugs you will have to buy the Button that goes inside the head. The R-Spec engine will be released in Late June.:D

any word on price for the new engine? I bet it will be high then it will go down over time, this is true for most products.

This is what Gijoe 64 posted a couple of answers back:

"The R-Spec will be avaible at the end of June at Towerhobbies. The new engine will cost more than the regular TR it will be around $179.99".

i didn't see it, i think i'm spending too much time on the computer:(

thanks for the price, i hope the price goes down over time.

i just called them and they said they should get the Turbo version in a couple of days with a new price. I hope it's $150 or below:sweat:

Hyper Head
 

Thanks, gijoe! I didn't even know a hyper head exhisted. I just ordered one from Tower!

ok, i just spent the whole day at the track. We had a race with touring cars and guess who got 1st place, a guy with a mtx3 with a OS TR-T:eek: :lol:

a lot of people ran mtx-3's and he also did too, you could clearly see he kept up to everybody in the turns but when it came to the straightaway he got smoked. At the 5 min mark all the italian mills ran out of fuel, and of course he was still going. The italian motors had to be restarted, while he came in for fuel and kept on going. You should of seen the look on some guys when they found out he had a TR-T and they had $250-300 motors and lost. After the race i asked him how much he got the motor for, he said $160.

Personally i think with better cooling and the right pipe the OS TR-T can probably keep up with the Italian mills on the straightaway:sneaky:

I have the os tr (p) te(spec) engine and it is very fast. I run the kyosho tuned manifold and pipe in my fwo5 r and it keeps up with the piccos sirios and rossis on the straights (i have changed to 39th diff ring gears) but it is faster in the infield and more drivable and never has flamed out on me once. The run times are much longer too. I like it but the other guys at he track hate that I have an engine that competes with them at 1/2 the price.

:) :) :) tat's why I like OS engines better....:) :cool:

what track were you at compaq?

i also have the OS tr on my FW-05R and its awesome

Hello from France ,

here's some pics of the TR T-spec 2004
- new cranck shaft ( higher exhaust diagrams)
- new machined piston (light and cut)
- new sleeve (for the new piston)

you can also see my personnal on the cranck (EFRA legal) and on the carburator.

My motors have at the same level than a JP mod or Rody mod with less consumption...
