On a rough track I'm running the same springs with AE25f and AE22.5r. I'm running 1.5x6 pistons that should have about the same pack as the 1.3x8.

You are correct!

Painted up a new body for my truck , came out a little pinker than I wanted but at least it will be easy to see !

I want to get the Buggy body and use it as an electronics protector for outdoor dirt tracks. Where is the best place to buy one and what would they be labeled as?

timamybrown, there is a chart or two in this thread that shows that,i believe it was posted to the first page if i am not mistaken

I feel your pain dude! I can't believe how noisy mine was when I first put it together either. I was like wtf lol. It will get a little less noisey after some run time but not a ton. I even tried different brand and size pinions and they all made the same awful noise.

There's a truck under all that.....

You are correct their is a piston surface area chart. That tells you witch pistons have more pack. If I run the stock oil front and rear the 1.3x8 will have more pack then the 1.2x10 hole pistons. I just wanted to know what is working for the guys that are already running them. Have they dropped down oil weight or went up in weight. Indoor track loose outdoor track. I'm. Trying to take advantage of the trial and error of the ones that have done the pistons change already. Or maybe I'm just being lazy lol.

a lot more goes into fluid dynamics than just the surface area of the holes. the frequency (number of holes) is inversely proportional to the size of the holes. so in reality, there is a delicate balance between the number of holes and the size of the holes. that doesn't even begin to factor in how far the holes are from the center of the shaft or if the piston is tapered or convex.

hope nobody bought any of that. just trying to sound like i knew what i was talking about for a minute.

We don't need to get that technical. Oil weight front rear with 1.3x8 piston would suffice.

With emulsion on an indoor track, I find that the chassis doesn't move around it's axis's as much ie. Roll center and C of G. It is more calm and controlled during any sort of transition. The truck lands jumps like a wet towel hitting the floor, and stays down after a jump. With a bladder setup, there is more activity going on in the situations mentioned above. The problems with emulsion are some inconsistencies in damping if not bled correctly, and bottoming tendencies on big jumps.
It is critical to get the exact same amount of air in each pair of shocks. Bladder is slightly more forgiving of this. If one shock has more oil than the other with bladder, the damping stays close, but the progressive spring effect changes. The bladder acts like a "buffer" almost. With emulsion, the amount of air effects the damping. It is also important to cycle the shock prior to a run to mix oil and air.
When I build emulsion, I measure the exposed shaft above the eyelet. I use 8mm for the front, and 10mm for the rear exactly.
Fill the shock and let all air escape. Put a little oil in the cap too. Screw the cap on quickly. Compress the shaft to your carefully measured amount, and put the sealing screw in. That is all it takes to build them consistently. I find that the Tekno shocks have the least amount of air afterward than any other shock I've built. I am using the plastic caps, and when I run bladder, I just leave the screw out. I get a little dirt above the bladder, but that doesn't effect anything. Then I can switch without buying new caps.
For the guys running a compensator or a harder bladder. Why??? The stock bladders are awesome. I'm sure a lot of R&D went into the material selection, why second guess it? If you are looking to gain something from doing this, please enlighten me. I think that the stock setup has more tuning options than most of us could ever use, or notice on the track.
