Picco Glowplugs
Can anyone tell how the picco numbering works with there glowplugs
What is the difference between a P7TH and P6TH (i gather TH means Turbo Hot and TC Turbo Cold ) but what is the difference between P7 and P6
Thanks
John

#6 is hotter than #7

5 is hot, 6 is medium (still pretty hot) 7 is cold and 8 is really cold.
Plus you have long and short bodied plugs. Long bodied plugs are a bit hotter, so a long bodied 7 will be hotter than a short bodied 7 using the same wire for both. Not sure what Picco's letter designation is for those but that is what the different letters mean.

So for a Picco 12 Evo 4 what plug would you use
for the 21 I was told to use a 7 cold

12's I like 6's for most conditions. Really long and really hot maybe a 7, cold as hell on a short track, maybe a 5.

#8
So what would the differance be between TH and TC
Thanks

Thanks everyboby for their help I understand now (wish it was written somewhere
Thanks

7TC
Wire Thickness: 7
Plug Type: T (Turbo)
Thermal Range: C = Cold, H = Hot. In Italian it would be F(fredda) = cold, and C (calda) = Hot
The plugs with cold thermal range, 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, have a body with thicker walls and longer body, so they retain heat and dissipate heat slower 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 thermal range, or Hot thermal range.
• With high humidity percentage we should use a Hot thermal range plug.
• If we have high temperature and high humidity, we should use a plug with thick wire and a Hot thermal range.
The best instrument to determine which Turbo Plug to use, are those digital weather stations, that have Temperature, and Humidity. 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.

In the novarossi world yes, H means cold.
Picco although Italian, TH means the short bodied hot plug. www.nitrohouse.com is a great place to get picco plugs and they show the package, the 6tc says cold on it.
I run the IDM variant but I imagine it is the same for all, I run the 6TH (or IDM6) everywhere all the time in the 12 evo3 and evo4. I run the 7TH (or IDM7) in the 21 for onroad and a 5TC (IDM5something odd) for offroad.
I don't believe in changing glow plugs even from when I break an engine in, with the 12 evo3 I usually go through 3-4 rods before the plug eventually pops. The evo4 I'm told has a superior rod so I guess it will go 3-4 gallons before the plug pops and it will eventually but I haven't had it happen so I don't know as I am still on the same plug with 2 gallons from nationals.

In Novarossi world, it goes like this
Example: The Novarossi C6TG (F) or (C)
Product: C (Conical)
Wire Thickness: 6
Plug Type: T (Turbo)
Plated: G (Gold plated)
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 retain heat and dissipate heat slower to the engine head.
