That's is very nice website information.

I solve my earlier problem ( short life of C7TF ) with C8TF.

I guess C7TF don't like 25% nitro with hot tropical climate.

Hi guys,

the long body plugs are longer OUTSIDE of the head button, the do not stick further into the combustion chamber. The longer body will dissipate heat quicker than the short body, that's why the plug is called "colder". The shorter body plugs heat up quicker that's why they are called hotter.

In addition to the different body style you have the different wire sizes. It can be very confusing :)

btw i saw they have a hot plug with long & short body and a cold plug with long and short body mean?

for example a hot plug with longer mean body mean hot but not that hot? lolzzzz....:blush::blush::blush:

I think you mixed up somewhere ....... C8TF is the coldest type, infact it is a short body glowplug. F means Freda, or Cold.

C8TC is the second coldest ( ranked before C8TF ). It is a long body glow plug. C means Calda, or Hot.

Here is the rank, from hottest to the coldest :

C5TC EXTRA HOT - long body = C
C5TF VERY HOT - short body = F
C6TC HOT
C6TF SEMI COLD
C7TC COLD
C7TF VERY COLD
C8TC VERY COLD
C8TF EXTRA COLD

Turbo Glow Plugs where designed to give more performance to an engine, for the following reasons:

*It forms an uninterrupted combustion chamber.
*The advantage of better heat transfer or heat dissipation, and a leak proof seal, generated by the conical seat of the plug.
*Greater choice of thermal ranges, that allow for more precise tuning according to variations in weather conditions (temperature, humidity, altitude, barometric pressure, etc.).

The numbers and characters on the plugs, are the product number, wire thickness, and thermal range of the plug’s body. Example: The Novarossi C6TG (F) or (C)
*Product:C (Conical)
*Wire Thickness:6
*Plug Type: T (Turbo)
*Plated:G (Gold)
*Thermal Range:F (Fredda = Cold) C (Calda = Hot)

The plugs with cold thermal range F (Fredda), have a body with thinner walls and shorter body, so they dissipate heat better and faster to the engine head. The plugs with hot thermal range C (Calda), have a body with thicker walls and longer body, so they dissipate heat better and faster to the engine head. The number of threads is the same on both types of plugs.

How to select the proper plug:
*When the ambient temperature is high, we have to use a plug with thicker wire.
*With higher compression, we have to use a plug with thicker wire.
*Humidity determines if we use a Cold (F) thermal range, or Hot (C) 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 table digital weather stations, that have Temperature, Humidity, and some also Barometric Pressure on them. 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.

Which one is dissipating heat better and faster now ?

Which one has less compression ?

OOPS!! mystyped,sorry, should read like this:

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

The plugs with hot thermal range C (Calda), have a body with thicker walls and longer body, so they dissipate heat slower to the engine head.

The number of threads is the same on both types of plugs.

Although never actually cc'd a head with each type, in theory the F type should give less compression, but difference should be ultra minimal

Sorry, I mixed it up, AFM is correct. :)

Hi friends,

pretty soon my N12-LL5 piston sleeve will be losing compression and thrown away.

Can I replace the piston sleeve from N12-RR5 ? or Plus12-3 ?

( my LHS don't have LL5 p/s/r. instead rc-mushroom has Plus12-3 and RR5 p/s/r in stock )

All three have the same bore x stroke, but I'm not sure with port's timing. :confused:

Thank you friends !!

I started breaking in my Plus 12-3SCT Tuned yesterday and am very happy with what I have so far and know its only going to get better.:nod: I'm currently using the 2630 pipe with 5 fin header, but I wanted to know what other options are out there to choose from?

Thanks,

Kelly

Great reading here guy's, I just wanted ask a small question.

This past weekend I blew my NovaRossi M12 in the pieces on the inside, now this engine was 10 years old so not totally bothered other then having to replace it so suddenly. I have purchased NovaRossi NS12TS1 and was just wondering if you all could give me a heads up as to what I am looking at as far as the engine goes? Will it be as good or better then my M12 was? I am running it in my Mugen MTX3 Sedan at http://www.rcpikeriver.com/default_e.html

Thanks Guys

Sean

The new engine is basically the same as your M12, with slightly different ports on the sleeve. Performance wise you can expect about the same.

Thank you, thats what I was hoping to hear. Maybe next year IU will look into the new 353 Race 12.

Hey everyone. I was wondering, this will fit my MT12 right?

http://cgi.ebay.com/ws/eBayISAPI.dll...2BSI%26otn%3D4

It says that the CX12N Piston, sleeve, and conrod set will fit the MT12. But the one I bought just says CX12. Someone on this forum said it will fit (In another thread) but I just want to make sure.

yes all you have to do is move the locating pin for the barrel.
