Really?? Then why the change on Rheinard and Maezumi's car?? Also, do we really need to get TA05 belts then if the difference only lies with the diff pulleys, because I'd have thought that you'd have been able to simply slacken the tension to make up that difference?
I am really keen to try it out, just want to make sure of everything that I need to get.

Not 100% sure why they are using the pullies but I think it a little more efficient with the plastic pullies. I have fitted TA05 diff/spool pullies on my MSX with standard white belts, you need to adjust the cams to the loose side

Great. So really all that you need to get is TA05 Diff Pulleys. Great!

It allows to gear for very low turn mod motors.

with the higher internal ratio, (2.25 with the white diff to 2.1875 stock) you would have to go up almost one tooth on the pinion to achieve the same roll-out ratio? perhaps the change is better suited for modified racing?

"Anyway yes with ran the different transmission, better punch and top speed and way more run time ! simply better in all departments."
Good thing I have some of the pulleys on order
HiH

Ed,
Have you just ordered the diff pulleys then, or the layshaft ones aswell? Any chance of some part no's aswell.... lol
Cheers

just ordered the diff pulleys (51212) and on-way pulley (53867) from Speedtech...hope I ordered the correct ones

how do you manage to fit the TA05 layshaft and centre pulleys???
Anyone tried it?

So for 27T Stock racers, the conversion to the TA05 centre pulley and diff pulleys is not worth it?

The white belts are more flexible than the black ones, because they are a different material (which is also quite crap in terms of longevity) that's the only reason why they sort of give a better efficiency. I've been running both types of belts and frankly can't tell the difference on the track, that's why i use black belts, they last a lot longer.
