The Mega/Exeed DS4 is the same build as the Picco EVO4 so all can be exchanged, if the rod of a Torque is the same as the EVO4, that I can not tell...

thanks! it will be my 2nd choice after my speed II. Novarossi seems too expensive on parts cost compared with os.

C7TGH plugs
 
Anyone have any experience with using these new plugs?

What makes the C7TGH plugs different from the C7TGF plugs?

According to Novarossi's website, the C7TGH plugs are meant for ambient temps of only 0 to 10 deg C??

If the above is correct ,then I purchased the wrong plugs?

If anyone has used these plugs for ambient temp range between 15 to 30 deg C, I'd like to know whether they worked fine or not.

Thx!!

I don't understand why it recommends 7 plugs for conditions that cold, and I haven't noticed that on the website. F stands for "Fredda" and H stands for Hot (same as C), and the difference is the thickness of the plugs body. The plugs with cold thermal range F, have a body with thinner walls and shorter body, so they dissipate heat better and faster to the engine head.

According to the information that I have 7H plugs are for much warmer weather than that. You can check the file attachment for the information that I always have referred to. I hope that anyone that disagrees or have better information will share it here, so we can all learn.

Appreciate the info!!!

The chart below is what confused me...it indicates that the #8 plug is the way to go...

Does your team have any experience with using the C7TGH with Flash21? If so, what are the drawbacks? Will they run equally well in our climate?

Appreciate!!

Does the special coating on the new pts slow down or even stop the amount of carbon that should build on the piston?

Not related. /still have carbon built up on the coating, and the coating will be faded.

pipe and manifold for .21 PT
 
I heard 2015 is not a good match. What are the best pipe and manifold combos for the .21 PT.

rias5037 07-17-2011 11:31 AM

You guys know what engine button from novarossi will fit in my max xxl3 .12?

im not sure on the pts, but i did notice on my jp the powermaster fuel leaves almost NO carbon behind at all, a engine guru told me it had to do with the type of oil they use, synthetic vs amount of castor within, not sure of all the geometry , but im pretty sure its the powermaster fuel, i noticed it in a second engine as well.. i was thinking to add a touch of castor to each gallon, to aid in the carbon building!!

For me, it has more to do with track than temp, though temp matters too.

Long straights, you need an 8 no matter what the temp is. Anything hotter is just going to get destroyed by all that sustained rpm.

Shorter straights, I usually run a 7 and sometimes even a six, especially if the weather is cool.
