Novarossi glow plugs ????
I am new to the hobby and it seems that novarossi glow plugs have very many choices to pick from can anyone explain this to me and if so is there a chart out here so i can understand thanks btw i just bought a (murnan modified novarossi .12 sct )

well im not running a Murnan but i got a 3SCT - Tuned and im running C7TF but gonna order some C7TFC (i think) they are the Ultra Version. just a better Quality plug. the 7 runs a bit cooler so u can lean it out a bit more and gain more top end

there is no glow plug named 7TFC
the number(5,6,7,8)/turbo(T)/gold(G) or not/cald(hot)(C) or freda(cold)(F)
a lot of combinations can be made

I think the .12 motors like hotter plugs, number 6 and 5. The shorter and longer body plugs will change the compression ratio of the motor slightly. I run 21 and generally stick with #7 plugs. Do a bit of research or ask Grinder what the best plug and head clearence is for that motor, two small things that will make a big diff.

Thanks for all the help but i still do not under stand all the codes of the plugs and when to use what plug in what type of condition????

For .12's I usually use 5's and 6's for the average short track. A monster 301 style track might prefer a 7.
Edit: Actually now that I think about it, the longer bodied plugs probably have a deeper hole so they might cause a very slight drop in compression, unlike standards where a longer body means the plug is deeper in the head and therefore slightly raises compression. I'll have to yank some elements out of some old plugs and check.

the long/short plug part is up top, not the inside the engine, so no compression change

Go with the 6F and if you are eating that plug go with the 7F, as said before, only on MONSTER tracks go with the 7,
have fun and I forget, run with 16% nitro, more is just waste of money

Even if the length is above the head it is still part of the compression chamber. Lets say that the hole where the wire is 1 mm x 3mm deep = 3 cubic mm. Now lets say that the long body plug is 1 mm x 5mm deep =5 cubic mm. It is volume in the squash area of the compression chamber. The numbers that I gave are not the correct sizes but I used them to show that the length of the plug would matter in the volume that the plug has. It is not much.

I need to spend sometime on there web-site to research this as the cost effective Ninja plugs are on the endangered species list...

I emailed fusion motor sports awhile ago and ask the about long and short plugs. Basically a long or short will not change compression. but the two plugs will hold heat from the engine in different matters. In the past most 12 engine where tuned with high nitro content and users used very cold plugs. that's when 30% nitro was the norm. Well since the price of fuel has risen some drivers are opting to go lower on nitro content (16-20%) with that being said; racers now could lower the deck head height and move to hotter plugs.
A hotter plug will give better idling and better low accelaration at the expense of top end. A colder plug might give a rougher idle and trouble clearing out the engine but once a little heat has been generated the engine will sing. I normally use cold plugs because my engine is shimmed for 25% but I do intend to move to 20% this season maybe 16% (If I can find a dedicated supply) At that time I would probally move to a medium heat plug.
