A nice find !

This 21T is suppose to go in the front at the mid bearing block to replace the stock 22T side pulley.

The stock 22T gives about 1 mm split (i.e. you need 1 mm smaller front tire than the rear tire to give a 1:1 overdrive). With the 21T pulley, it'll give about 4 mm tire split ! So if you run 64 mm rear tires, you need to use 60 mm front tires to get 1:1 overdrive.

Else, you could use this 21T pulley as a tuning aid. A lot of people put there like to run the car with front overdrive. Especially on short tighter tracks, it is nice to pull the cars out of tight corners.

Ummm, I guess with this first pulley being aluminum, Serpent would come out with an onslaugh of aluminum pulleys for the rest of the car...

p/s: I notice Serpent is listening to more of the requirements of racers who run on shorter tracks. Also new is the 20T pinion (802520) which is suppose to give a higher 2nd gear ratio from 5.09 (57/21 combo) to 5.34 (57/20 combo).

I would be interested to know how different it is using this 21T side pulley against Pyramid / Goldfinger's 46T rear diff pulley...

Pyramid / Goldfinger, has this 21T aluminum pulley arrived on your shores yet?

Ooophs, I thought I replied to this...

I guess it's a matter of preference. Some people like the front diff better than the front solid but I like the front solid better. I would rather go with a solid front first and then work on the setup to get more off power steering back.

You could take a look at the setup I posted recently at 3hobby.net. For other tracks, just change the gearing or perhaps the tire shore to suite.

When you say locked-diff, this would be the one-way locked with the pins?

How do you modify the front ball-diff to be locked?

Cheers, Mark.

[For me, my preference is for the front-diff, simply because it is more tunable. I don't think the front diff is lockable in its standard form. You can tighten it so it is pretty hard, but attempting to tighten it so much to make it solid may result in damage to the diff collar (this is my assumption).

When I get back to my circuit, I will, however, try out D's suggestions for the front solid. I have already run it and it was very nice - I simply haven't done back-to-back tests yet.

No. He took the front ball diff axles and pulley and physically locked it. So there's no more diff action on his front "ball diff" anymore. Don't know the details but Uncle Crash thought he heard him say that he locked the front ball diff with a glue. I actually did not take a close pic of it but he took off the diff collar too as it was not required.

Very interesting No doubt a mod we'll be seeing on a car not too many miles away from D in the near future

Precisely. Like some friend of mine told me, it's passe.
