ok, i got the RB v12 turbo, but i have problems with hooking it up to the v one rr transmission because the 2nd gear pinion is touching the 1st gear spur, any advice?

compaq888 07-20-2004 10:30 PM

nevermind, i had the whole assembly on wrong and even the clutchbell wouldn't spin, now everything works, just got to fix the little stuff.:sneaky:

And i put a more aggresive gearing, so it should give me more top end and more bottom end, can't wait to see how this car drives.:D :sneaky: :tire:

By the way, Nippon, please snap some pics of the internals of the E-Spec you have there. :cool:

FFR3582 07-21-2004 07:01 AM

I just canceled my order with Tower and then reordered with the 15.00 off code.

I figure if i have to wait awhile to get my motor I should take advantage of the current discount offered.

compaq888 07-21-2004 10:32 AM

you should of ordered last month, you would of gotten $20 off your order. You won't get the engine till the beginning of September maybe you should cancel and wait for a better discount.

I'm going to order mine now too, except that I have a $20 off code. That will make this engine only $159.:cool:

This is about as big a discount code as I'm going to get, and it ends this month, so I figure I'd use it while the usings good.:nod:

OS Turbo plugs...
 
i don't know much about turbo plugs, and since I'm going to be gettng this engine, I figure I should start educating myself.

Q: Do the turbo plugs follow the same general usage guide lines that non-turbo plugs follow?

-What I mean is, I run 30% in my current engine. This of course requires a cold plug to avoid detonation. But while reading the RC Car Action recent issue, they say to use a hot plug anytime your running turbo plugs.

Q: Is the OS T-P6 hot turbo plug (included with the R-Spec) okay for 30% nitro?

-Or should I go for something a little cooler like the T-P7 medium or something much cooler like the T-P8 cold?

Just gathering some info ahead of time.

Just gathering some info ahead of time.

Here you have it........

The numbers and characters on the plugs, are the product number, wire thickness, and thermal range of the plug’s body. Example: The Mega Turbo 2315 6TF

Product Number: 2315
Wire Thickness: 6
Plug Type: T (Turbo)
Thermal Range: F (Fredda)(Cold)

The plugs with cold thermal range F(Fredda), have a body with thinner walls, so they dissipate heat better and faster to the engine head. So because of that:

·When the ambient temperature is high, we have to use a plug with thicker wire.
·Humidity determines if we use a Cold (F) thermal range, or Hot (C)(Calda) thermal range.
·With high humidity percentage we should use a Hot (C) thermal range plug.
·If we have high temperature and high humidity, we should use a plug with thick wire and a Hot(C) thermal range.

The best instrument to determine which Turbo Plug to use, is those weather panels they sell for Yachts, that have Temp, Humidity and Barometric Pressure on them. Have it calibrated at your local weather station, and bingo, you’re ready like the Pros.
That is the key to success or failure tuning engines with Turbo Glow Plugs, because they are so sensitive to weather variations that is unbelievable.

Following is a selection chart for Novarossi Turbo Glow Plugs:

Type Thermal Range Nitro% Temp.C Humidity%

C5TC Hot/hot wire 10-20 0-10 70-100
C6TC Hot/average wire 10-20 10-16 70-100
C7TC Hot/cold wire 20-30 16-25 70-100
C8TC Hot/ultra cold wire 20-30 25-up 70-100
C5TF Cold/hot wire 20-30 0-10 40-70
C6TF Cold/average wire 20-30 10-15 40-70
C7TF Cold/cold wire 20-up 16-25 40-70
C8TF Cold/ultra cold wire 20-up 25-up 40-70

Now, there should be some chart for OS plugs in their site that explains their range and applications the same way as per the Nova range.

Hope this helps

i may be way off but i was under the impression that you just about always want the hottest plug you can get for a .12 and adjust detonation with shims. ask motorman or dino or palmaris, they know everything.

Darkseid 07-22-2004 12:26 PM

Well I had never heard of anyone suggesting a hot plug for 30% nitro applications, regardless of shimming. The current Nova Rossi plugs that I use now(C6 cold) say they are specifically suited to 30% nitro usage.

Duhhh....on me. I didn't even think to check there first.

I just found it odd that RCCA turbo plug guide says to "use the hottest turbo plug availible", while they did not take into account the type of fuel being used.:weird:

Well as you can see by my last post, it isn't allways like that. You have to take into account WEATHER, and NITRO%, and NITRO% determines the right shimming of your engine.

As per OS Turbo plugs, they have three types rated by ambient Temp:
P6 for low temp applications
P7 for average all season use
P8 for high temp applications

gijoe64 07-22-2004 02:51 PM

Try the new P3 super hot plug. It will give you about 500 more RPM's

It is getting very "late in July" does anyone have a motor yet or any new information on the ship date?


:D

rodneybarrett 07-27-2004 07:19 AM

don't expect these motors until late August.

I don't know why Tower still has that "late July" listing there. Both they and OS has comfirmed to me through email, that the R-spec wont be reaching retailers until "late Aug".

Towerhobbies or your local hobby shop (if they deal with GreatPlanes) are the ONLY places to get OS in the states. So if you really want one, I would suggest pre-ordering now at one of those locals. I have and I know a good number of others have too. I went with Tower since I know they'll get them first.

Darkseid 08-09-2004 09:25 AM

NOTICE!!!
 
Anybody who preordered the R-spec on Towerhobbies might want to give them a call. It seems that Tower is lowering the price for Aug. and that means more savings!

I had mine reserved for $179 with a coupon code for $20off. Now, the new price is $159 and they will still apply the coupon code, so that means the engine will then be $139!!!:cool:

***note***If you go to their site and search for the engine, the main page still shows $179, but if you click on the engine to go to its information page, you'll see the new price of $159.

Now I don't know if this was a mistake on their part or if they are really putting it on sale like I was told on the phone, but either way now you know...


-Just spreading the knowledge...:cool:

BigDogRacing 08-10-2004 07:07 PM

Just wanted to let you guys know that my E-spec was awesome on it's first race this past weekend!! Ron Atomic (O.S. sponsored) came to Memphis and raced with us. The track was fairly slow for nitro so we couldn't tell if my box stock motor was comparable to his motor on the big end, but down low and mid-range it was wicked fast. I ran an R6 turbo plug and kept the tune around 230-240. Unfortunately my driving wasn't near as clean as Ron's so I was about a second per lap slower (18 sec laps) than he was consistantly.

We had a great time and I couldn't be more pleased with my motor.

Darkseid 08-13-2004 12:02 PM

That is good news. I'm very ready to get mine. Tower bumped the engine up to "Mid Aug." so maybe it will be in around the end of next week. If not, late Aug. is still acceptable.

Darkseid 08-14-2004 11:52 AM

The R-Specs are instock at TowerHobbies! My backordered one is being packed up to ship out on Monday. I should have it by Wednesday!

Whoo...hooo...:D

rodneybarrett 08-14-2004 12:46 PM

yep. mine too. However for some reason the discount didn't get aplpied correctly. I did buy it at $159 but there should have been a $20 discount too. I tried to call and Customer service was already gone. I'll try again tomorrow or monday.

FFR3582 08-14-2004 01:57 PM

That is great news, I have a race coming up on the 21st. I want to take it with me so I can drop it off and have it modified.

How are you going to know what you have gained with the mod if you never try it in stock form???:confused:

Don't worry, Tower's custormer service is great, they'll hook you up.:nod:

FFR3582 08-15-2004 07:19 PM

Most of the people that I know of that do motors don't work on used motors. I also don't care what it does in stock form I only care about what it will do when it is modified.:)

If I have it by the next race I don't have to ship it to the guy, or if I get it real early in the week I may be able to ship it and have it delivered back to me by the race.

S.Stew 08-15-2004 10:32 PM

anyone running a TR on a track about 200-250 ft long? Any thoughts?

My budget ran short for nats and i need to know if theres even a point in me going cuz im gunna get motored all week.

oh, I got ya...

BigDogRacing 08-16-2004 09:40 AM

Just a note for you guys that want to mod a TR r-SPEC- if your motor man hasn't spent a LOT of time with the TR R-spec don't count on them being able to make a lot of extra power. I've learned from Ron that these motors don't respond to the "normal" mods like the italian motors. The torque curve on these motors is lower and they need different porting. I'm not sure if Ron's motor guy is willing to do work for other people but we can find out. If you would like to ask him yourself email Ron from www.kinetixrc.com .

Further info- if you are running typically short tracks then don't waste your money- the motor is awesome down low. It has TONS of low and mid range power. The only place it needs any work is high RPM. I'm VERY happy with the motor and wouldn't even think about buying something else.

one last note- for you guys that think a nitro motor needs all this bullshit break-in procedures with rich idle and crap... PLEASE. I don't have time to go into the specifics of why a race motor shouldn't be treated like that (which I can do later) but just start the motor, watch the temps, tune the idle, then ease into the high speed settings. Keep the racing temps around 220-230 the first few runs. DO NOT run the motor so rich it runs like crap- that HURTS a race motor. DO use a heat gun o to heat the head and block before you start it the first time. I've already run almost a half gallon of O'Donnell 30% through my motor and it still has so much compression it gets stuck where the starter box can't spin it- I have to back it up with my fingers to get it inbetween compression strokes. :) :nod:

Darkseid 08-16-2004 12:16 PM

30%...
 
Hey BigDog...great post...By your discription, I should love this motor as much as I did my original TR....with just a little more power!;)

I got a couple questions though. Did you have to do any additional shimming to the head to run the 30% nitro?

Also, what temp plug are you using with it, the P6 that came with it?

Thanks

-Darkseid

BigDogRacing 08-16-2004 01:58 PM

Dark- no I didn't shim the head at all. I'm using the R6 plug. I believe it's the Sirio R6, but pretty much the same as the P6. Just so happened I left the P6 at home so I used a new R6 that was in my box. It runs good, but I can tell by the idle characteristics that it could use a plug just a hair colder or hotter- not really sure without trying it.

Darkseid 08-16-2004 03:29 PM

Thanks for the response...

Racing4Evo 08-16-2004 10:36 PM

I'm getting mine next week. Great deal! OS has got to be the only thing Tower hobbies sells at decent prices! :lol: This is going to be my short track motor and maybe another one as a practice motor.
The only thing I'm concerned about is fuel consumption.

The TR R-Spec motor can hang on any large track the testing on this motor has had very good results on large tracks. The R-Spec can hang with any Italian engine. For the Nationals several drivers will be using the R_spec engine.

Darkseid 08-17-2004 12:35 PM

My thing with OS is reliability. My first year in nitro touring was all about one thing. Reliability! So last year I went with a 12 TR. It worked great. Was slightly under powered on the straight, but was awsome on the in field.

This year I wanted a little more power and was willing to sacrifice reliability a bit. BIG MISTAKE! I've missed more races because of engine problems this year, than I did all last season! Tuning and air leak problems were consistent with my Sirio.(original, not the new and improved EVO2). I even snapped the shaft on it!

So I'm getting back to basics.....my old reliable OS. I stuck my 12 TR back in after it had been in preserved storage for almost a year. Fired it up, readjusted it for 30% nitro (I ran 20% last year) and it was instantly more reliable than my engine this year.

Now comes my R-Spec. I'm hoping it will bring the reliability of OS with a little more 'Sirio like' power on the straight.<fingers crossed>

All I'm really hoping for is that the 11A carb is as easy to work with as my 10J was. Cause after working with my Sirio, I must say that so far, I'm not a big fan of true three needle carbs. Damned...low end needle....:sweat: :lol:

Racing4Evo 08-17-2004 02:36 PM

It's just the carb on the Sirio. After you switch the carb out it's an awesome motor.

That's good to hear. I'm getting 37t ring gears for my car and I can't wait to drive the car at the regionals maybe with the OS.

Yeah, the improved carb on the EVO2 is much better. When it came time to replace the snapped shaft on mine, I looked at the $55 price tag, then the trouble I had with the engine, and I just passed on it.

Racing4Evo 08-17-2004 03:29 PM

You can even use an OS carb. Lunford racing makes an adaptor that slips over the neck of the carb then you insert the whole thing into the crankcase. That should give you reliability.
