Picco Plugs
#17
I do not own a Picco plug, de idea was that people can list their plugs.
From an old G1-pro engine I still have some parts and so I could messure the hole for the plug.

After the GLC I will take time to make some measurements for accurate comparisons. I have not had to tighten OS plugs any more than normal for a turbo. Nor have I seen anything unusual when looking at it with button removed from engine.

I have an old head button off of my JL Evo 3, an O.S. P7 plug and an ofna 51006(picco) sitting in front of me and there is an obvious difference in the way each plug seals. The picco sits absolutely flush in the chamber and looks almost like it's part of the button. On the other hand the O.S. sticks slightly in the combustion chamber and I can see a gap around the plug. If you sit the two plugs side by side, the difference in taper is obvious.
Now the question is, does it make much of a difference?
As soon as my camera battery charges I will try to take some clear pics to show what I am talking about.

Why didn't they create 1 standard turboplug?

Now that's the 1 million euro question.... money,money,money
Glow plugs are expendibles. If Picco never sells another engine they can always bank on the usage of their glow plugs.
I pose this question to one of popular rc mags. His first reponse was money.
the second reason is to maintain the proper timing of the combustion process(bogus) It's money!!!!

Well let's put it this way, if this were the case then the company with the best performing/cheapest plug would be selling them while all the others would have shelves full of unsellable plugs.
It's actually quit clever because I would never pay $10+ a plug for the piccos if it weren't for the fact of having 3 red dots. However, I have never tried to run the motor with any other plug.

Well I'm going to get some of my turbo plugs and place them on a Optical Comparitor( a huge magnify glass that measure distances on a cnc axis). I should be able list all of the critical measurements of different plugs. I will post my findings tomorrow.
Pass you soon...

Ok, here are the pics I promised. The first two are the O.S. plug and the last two are the picco. The last pic shows the difference between the two.

Here's the data. I used the same measurement points as the picture. I did add one dimension G. Which is the angle of the taper in degrees and minutes From straight verticle (up and Down) to the taper angle. Some of the points I measureed from are not true angles but radius; so those dimension can very by .05mm or .002/in. All measurements are in millimeters.

head buttons
What head buttons will fit a new picco engine? Are sizes and bolt patterns different? I havn't been in .21s long enough to compare different motors.
Thanks for the info.

the Ninja plugs are a real close fit. I never had issues running them in 1/8th and in fact they last way longer than other manufactures.
On the issue of money concerning these things, why are exhaust gaskets so damn expensive! At my local hobby shop they wanted 7 dollars for one RB exhaust gasket! There must be an alternative! any suggestions?
