Don't know the logic in your findings. But what I found is that the 4x1.2 mm with 40 wt oil (or 5x1.2 mm holes with 50wt oil which is slightly harder) is somewhat the same feeling as using 30wt oil with 4 or 5x1 mm holes.

Also what I found is that harder tire shores have better and more consistant SIDE BITE as compared to softer shores with the same set of shocks. For high speed tracks, I would use harder shores if permitted because they handle high speed sweepers better. Softer tires would hook the car and the feeling is not too consistant on high speed tracks. Technical tracks where you need the car to behave and react quickly, softer tires are better. Of course, these are just my findings...

I drive the 710 and I'll be very biased if I tell you why I like the car.

Actually, driving the 710 or any Serpent car does not make you knowledgeable. But I do not deny that driving the Serpent has sparked my interest to know more about the hobby and designs of other cars in particular. I find learning new things fun and at the same time challenging and very fulfilling. More so when you do it as a hobby. It is very satisfying to apply what you know against what you do on the track and see their results coming out the same.

Yes, could be.
But I still think that piston hole or diameter were dictating the piston speed And the visco is purely resistant weight.

I got 1 question that keep bothering me, with same setup do you
need to use 1 step harder tire shore for final run?
Sunny day (50-60 track Temp) and cooler afternoon(40C track temp)

I guess so. That's why Julius say that they are different although the "feel" the same.

I believe most people run harder shoes in their final run because of tire wear.

Generally, I found that harder tires are also better when the track is hotter. When the track is cold, soft tires are better. Soft tires only provide marginal performance in terms of traction compared to harder ones when the track is hot.

I guess at the end of the day, you need to test the different tire compounds out on the track to determine what handles best.

Sorry I don't. There are very few tracks that I can drive the 1/8th scale.

Default Sandblasted piston

I have been living so long with the nightmare of ruining my wonderful NSR12S3... now is happened.
Maybe I used a too hot plug (6TC with 18C temp and 16%nitro) or maybe I was too lean (about 4 1/4 turn out HSN).
The plug broke and filament scratched piston side. Top of piston is also sandblasted. See pics
The motor run about 8/9 liter.
What can I do?
