I plan to get an evo2 soon and I'm going to run in the stock class. I'm planning to get the paradigm monster and I wanted to know if anyone could recommend me some good 64pitch gearing combos for a small, a medium and a large track. I would like to have setups for all 3 types of tracks

This picture appeared in this thread a while back, somebody pointed out that the diff pulley had had every other tooth removed.

I just wondered if anyone else had tried this, if so how did you remove the teeth and was there any noticeable improvement?

Thanks

The people At Pre-worlds Were doing same thing. They were just removing it with a Dremel. I asked and it was to free the drivetrain. They only did the front though.

Thanks, any clue as to why the front only? Were these guys running one ways or the guys running spools?

I run stock and this looks like a nice little tweak if I can do it neatly, I'd do it front and rear though.

With the layshaft being closer to the rear diff I think there'd be more 'wrap' around the rear pulley and so the rear shouldn't have any addiotional trouble with skipping?

On the other hand just looking at my car the rear belt is very slack...

I have the old 3rd party low ratio pulleys as well as a Factory kit arriving in the next few days - I think I'll take the dremel to the 'spare' pulleysand see how it goes.

If they didn't do rear I wouldn't Either. THey were running One-ways Upfront.

Josh said that they were running spools to get ready for the Reedy race as well.

I think that article said that two of the 4 XRays in the A were running spools. The picture was of Josh's car I believe but not from the pre-worlds.

He said he was running a spool at the pre worlds - that's why I asked about spool/one-way. I wondered if the one way meant there was less chance of the belt skipping, perhaps because skipping is more likely under braking than power?

Doh, yes it's obviously a spool.

I guess my point was that the car pictured was using a spool and there was no mention of skipping when it was originally posting so it must have been okay.

Also, there's no possibility of belt skipping under braking with a one-way.

Dotman, yes that was my point, I just needed to establish that the mod was OK for a spool or a diff and not just for one ways because as you say no braking force on the belt with a one way.

I guess i'm not being very clear...

Thanks

Is it something you'd consider trying? or a waste of time?

Now we've established that it's not a one-way only mod, I'm still wondering why the pros did it to the front only... I think the belt wraps ever so slightly more on the back pulley, 50/50 power split so why not the rear as well?

I guess I'm going to have to trawl the whole Josh Cyrul thread to see if it's covered in there somewhere
