Over driving front diff 501/511

[MHeadling]

Where we race a Faversham on a slippery wooden floor on Sch Full Spikes some of the top lads are over driving the front end of the cars and it seems to be working well.

I want to try this on my 501, I have the big pulley conversion, Does this have 37t diff pulleys? What are the centre pulleys ?? tooth.

Is it just a case of using an orginal 501 diff pulley and what tooth size where these??

Is it there an option of running the 37t diff pulleys all round and chaging one of the front pulleys by the spur for a smaller version??
