there is not enough weight in the plastic pulleys to make a difference, the transmission will also spin at the same speed.

its all about belt tension,

How can different (lower) internal ratio makes the shaft spins at the same rate/speed? I might be wrong.. thats why I ask

I think the reason behind the low internal ratio pulley set is just the exact same with one of the design purpose in Serpent S710 ( or it maybe the other way around, the design of T1 low internal..... that inspired the S710).

but we are always short on parts with
the evo2 foc now so what about supplying the demands on the parts for
the evo2 and the other kit out there that
Xray have and lets have the options parts for the kits as options and not a
new kit, because I just bought my evo2 kit and to hear that a new kit will be out
soon, man that depressing, that is my opinion and not to bash XRay, well XRay keep up the good work, I live the win and drive a XRay.
The new kit will just include the updated parts, you will be able to get them for your car.

the diff will spin the same speed(as if you were using the old ratio) unless you change your final drive ratio, the layshaft pulley will spin faster than the original pulleys did, the ratio may be lower, but the gear is higher. the parts are so small, lightweight and all of there weight is in such a small diameter, the difference is negligable.

this not what makes the difference anyway, its the belt tension.

Dr. Smooth

The factory kit is just a refinement of the Evo 2 with some parts that are available as options.
Short arms, ligthened outdrives and wheel axles, Bulkheads with new roll center positions and C Hub ONLY.

The car will make the official appearance on the Nuremberg show I've been told.

The description was a little loose but these parts can be seen in some photos of team cars since mid year.

The car will last for the entire 2004 season with no planned versions or models being released.

I saw the info leak a while back and even some photos of parts in this topic, but I know from a very reliable source that the car is here to stay for one year....

The parts are compatible all over. In fact as time went on I upgraded my car to the same config, regarding diffs, ratio, c hubs etc etc.

The only things I'm missing are the short arms and the new front bulkheads.

You can see them here:


Now compare that to the Yokomo SD 3 versions in 6 months

Dr. you got PM

The main difference with the front bulkheads is the point for attaching the camber link.

On "normal" cars the link attaches to the suspension tower. Like this they can slip washers under the link and change roll center much easier. On the tower we would need a lot of holes and would never achieve such a fine degree of roll center tuning.
Like this the washers can be as thin as we like (well, almost)

Notice that it has a slope cut so that the camber link can attach correctly. The normal ones don't have that slope cut.

Actually aditional to that the bulkheads have aditional roll cented adjustment on the arms front and read the have also been substantially lightened.

Looking at the pictures od Josh's car ( http://www.rctech.net/events/clevela.../index10.shtml ) it seems that the bilkheads are ligthened to a great extent.

Nice photos, I notice that the pivot are on
the out side of the bulkheads I guess
those are the short arms, but what advantage the short arms have over the
stock arms.

You need a new layshaft too - 1.77 doesn't use the center one-way. (at least, this is what it should like from your question - was it the *small* pully you are asking about?)
