What are the advantages to using 17t or 18t center pulleys over the stock 16t size?

The advantage is you can run your belts looser without having them skip because of the increased belt wrap.

How do I figure out the internal ratio so that I may figure out the final drive if I were to change the center pulleys?

Simple division. 36/16=2.25 to 1 and 36/18=2 to 1

My question is about the belts, I still run the belts that came with the car and check the tension after every run, but during my first heat I could hear an unnatural sound coming from the vehicle and about four minutes into the heat the vehicle slowed down as if the batteries had dumped. When I got back to the pits I noticed the the front end was spinning more than the front and figured the rear diff had failed, but after further inspection I realized that I had the belts teeth clean! Is this because of the torque of the motor or could it because I've switched the diff pulleys to the 36t alternated variant?
Also how long should I expect the delrin drive cups to last on the front spool with the bl motor I'm using?
Thanks in advance.
Hi,

I used the normal full teeth white coloured pulleys up front as I'm afriad that it will slip when using those hot mod motors.(I using the 3.5R)

The Delrin outdrive if you're using the MRE's, then it should last you quite awhile.My current one have gone through about 30 packs and still is ok.

You don't break belts anymore because the belt is muh less stressed. I have been running 18T pulleys for more than a year now and I have gone through 2 belts in that period of time. Before that I would go through a belt every 2/3 meetings.

Did Tamiya release their 18t center pulleys or do you still have to buy that after market one?

I believe it's the same as the MRE! But, I'm not positive. The only difference on the MSX and MRE was the rear arm spacing so, I think the spacers on both are the same!

Tek, I think you can use the 18t pulley from the 501X, if you can find some.

A top deck from an MSX won't work, you can use only the MRE or MSXX top deck. I don't know of any aftermarket top deck.
