With this exeption, that our yearly meeting still needs to be
held, so the regulations will change, as you could read in my previous message, I was talking about the old regulations.....

You are right. They are both short stroke engines.

Corey: I know what Uriah says about the timing. I believe what Mugen and Novarossi say. They say the engines are the same. I had both and they ran the same for me. Either way, the NS12S3 is a good engine.

ABOUT TURBO GLOW PLUGS

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.

Following is a selection chart for Novarossi Turbo Glow Plugs

Type Thermal Range Nitro% Air Temp.C° Humidity
C5TGC Hot/hot wire 10-20 0-10 70-100
C6TGC Hot/average wire 10-20 10-16 70-100
C7TGC Hot/cold wire 20-30 16-25 70-100
C8TGC Hot/ultra cold wire 30-up 25-up 70-100
C5TGF Cold/hot wire 10-20 0-10 40-70
C6TGF Cold/average wire 10-20 10-15 40-70
C7TGF Cold/cold wire 20-30 16-25 40-70
C8TGF Cold/ultra cold wire30-up 25-up 40-70


Hope it helps

Thanks, that is very useful information.

So if I am using 30% nitro with an average temp of around 80 degrees (F) and a relative humidity between 70% and 100% your table would recommend a C7TC (I cannot afford the gold plated plugs). Do you agree?

Thanks for the help.

Default novarossi top 8/sn??

hi
anyone heard of this .21 engine? was given to me by lhs to test out if i liked it but upon opening up it looks very simple..3port design, abc construction, slide carb, standard 1 piece head.

is this engine competitive? looks like its a basic .21 that will not produce much better..then again it may be a terror?

Right....weather in Florida is like our summer, so we've been using C7T's for ages...just be carefull with humidity % Use C's for over 70% and F's for under 70%.

thanks... i'm looking at the 12+3 sct version. haven't had any experience with ceramic bearings. that's why i'm asking for any opinions or feedback about this..

The Plus 12-3 SCT is different to the Plus 12-3CT. Both have ceramic bearings, but the SCT has a different diameter crank and bearing. It is 11.9mm rather than 11.5mm diameter. I've been running one for the last few weeks and it is gun.

Also, after extensive testing with pipes, we found the Novarossi 2630 to be the best! The pipes tested were, Mugen 2501, Sirio 2611, Novarossi 2601, 2602, RB 2604, Skyline VR12, VR12 Plus.

thats right, the 2630 pipe seems to be the best for the plus. i use it with the short (5 fins) manifold.

Darren Johnson has used on the Euro 2006 in Heemstede the 2601 pipe with the short (5fins) manifold. I talked to him and he said that the bottom power is much better with the 2601. He also said, that it´s more important to change your gear transmission.
