Default Hot Bodies E817 3.5 D Block

The owner of VRP, Mike Ankey, has been running the Hot Bodies E817 buggy for a few weeks. He noticed it seemed a little loose in general. So, he wanted to add rear toe. Problem was, HB is out of the new 3.5 Degree Toe Block for the E817. So, he drew one up and cut a few. He tested it this past weekend with good success. The added toe locked in the rear end.

So, we are offering the E817 3.5 Degree Rear Toe Block. This is a straight block that locks into the chassis like teh stock block, but uses a delrin spacer to take the place of the rectangle section that is locked down to the chassis.

We will be selling them for $20, plus shipping. Pm me if interested.

I think for the next race I may try the VRP pistons I got here, or, if I could work a swap of the 3 x 1.3mm pistons I have with VRP to get the sizes I am using right now, I would be interested in that too. The pistons are NIB.

Dang, I just ordered pistons and the body shelf for the B6. Is there a way to add this FREE motor plate to my order?

Still trying to understand how the EU piston varies in feel to the non EU

Well, Awesome! lol

But that's ok, out of the VRP1227 ones, I'll take the VRP1253 one instead.

Could you not just drill a set of EU 2x1.6 to 1.7 hole sizes?

The EU work better on high bite tracks. The way the sidewall of the piston is designed reduces friction and provides better stability on high grip.

Its pretty cool they did a promotion like that. if they are looking for promotion ideas, a buy 2 piston packs get 1 free would be a nice one too

Roger - don't trust myself with drilling and don't want that variable in the back of my head. Since you replied, if you don't mind, what do you use in your rb6.6 in lower bite Astro (since you don't race clay)?

Pretty much always 2x1.6 front (500cst 50cst) and 2x1.7 rear (350-400cst).

On very bumpy slippery tracks I have run 3x1.4 both ends (450/350cst).

yeah I am still trying to wrap my head around when to use a different piston hole count. I reference this from Dino_D:

Quote:
Made a little chart to show hole area and hole sizes.

mm..........2.......3......4.......5.......6..
1.0......1.571 2.356 3.142 3.927 4.712
1.1......1.901 2.851 3.801 4.752 5.702
1.2......2.262 3.393 4.524 5.655 6.786
1.3......2.655 3.982 5.309 6.637 7.964
1.4......3.079 4.618 6.158 7.697 9.236
1.5......3.534 5.301 7.069 8.836
1.6......4.021 6.032 8.042
1.7......4.540 6.809
1.8......5.089 7.634
1.9......5.671 8.506

As you can see 2x1.7 will have similar STATIC pack to 3x1.4 or 4x1.2 or 6x1.0.
When you move the shock shaft slowly, the differences between them is not that noticeable. However, the differences between fewer larger holes and more smaller holes is when the shock starts to pack. Less holes pack late in the stroke. More holes pack earlier due to more turbulent flow from more holes. Normally I alter pistons size and holes to adjust for track conditions. Bigger holes also favor bumpy tracks, but will bottom out more on larger jumps, smaller holes are preferred on smoother tracks with larger jumps.

I don;t have a chart referencing piston sizes (area of the holes) and oil weight combinations as there are too many different brands of oils.

Remember, oil weight is used to control the weight transfer front to back and side to side.
You can match heavier oil, and more holes or larger oils and light oil with smaller and less holes to achieve the same damping ratio, but heavier oil and larger hole area pack later in the stroke. Lighter oils and smaller hole area pack earlier in the stroke. It depends on what you want to achieve with the car.

Normally I tend to figure out what oil I want to use (heavier for fast flowing, high grip, and lighter for smaller technical tracks) and match the piston sizes and holes accordingly. Bigger holes for low grip and bumpy tracks, smaller holes for higher grip surfaces. Smaller holes for larger jumps. Just need to find the perfect balance and it takes time to test and find the right combination.

This is my opinions and testing. Feel free to experiment and try.
So my question is when do you want more holes versus less holes, assuming static pack is the same in laymans terms? (higher traction, want more holes, loose bumpy, less holes)
