Pops, perhaps you should not talk offense so easily. Neil is only offering a suggestion and did not intend to disturb you.

He did not say YOUR spring tension and YOUR driving style did he? If people were to rip on each other by providing advice based on experience..all anybody would do is disagree.

My experience with Tribo is a mixed bag. Yes, it feels like it has a little more power on track (not much but enough to make you want to use it at big races) and yes it also gums up the brushes if you use too much.

Thanks for the support Rod. Looks like I hit a nerve with Pops, which I didn't even intend.

Guess who got a partial?

One thing we have found with the Monster motors to get more torque out of them is to put a timed cut on the brush but put it in backwards...To take timing out. It will knock off around a 1000rpm but will bring the torque and power up.

Hope this helps.

Eric,
Mind giving a little more detail on how this is done? Thanks man. I have heard different things and am somewhat confused...

Rob just take 10-15 thousandths off the leading edge of the brush...Normally you would take about the same off the trailing edge. You can also run a very small hole in the center of the brush after you de-time it to help brush contact.

I can take a pic of a brush later if you need.

Leading edge.... When inserting the brush into the hood you are talking about right side as the leading edge??? That is what is confusing to me. I have seen the cut that Todd puts on his brushes, but get contradicting answers on leading and trailing.

The leading edge would be the right side. Todd cuts the trailing which is supposed to help torque.

Actually, a leading edge cut will advance the timing and make the motor spin faster to the sacrafice of efficiency and torque.

A trailing edge cut will retard the timing and make it more torqy and possibly help the efficiency.

I've found that a hole in the positive brush will help the efficiency drastically and push the rpm up a bit. Power stays the same with a shift to the higher end. Torque drops.

Cutting the corners off of the trailing edge of the negative brush should reduce the arcing and burn, though I don't have enough experience to comment on the torque and power impact.

I need more torque and wanted to confirm the trailing edge cut. I've never tried it before. I'll probably try it tonight with some 4499s so I don't waste my Putnams on it. If it works, I'll do it to my putnams.

How would cutting the leading edge advance the timing if it delays where (in realtion to) the brush makes actual contact with the next contact on the comm? It doesn't. It retards the timing. Your thinking must be a little backwards there sands. You can rest assured that EA has forgotten more about race motor tuning than most of us will ever know.

EA- WHY YOU TELLING ALL THE GOOD SECRETS!!!

advancing the timing on a mod motor means turning it more in the direction of rotation. looking at the end bell, this means turning it clockwise. From say 12 deg to 32 deg. Last time I checked (I still may be wrong, need to check this out tonight) this meant more speed, less torque.

The same can be done with a fixed endbell by trimming the cut of the brush.

http://www.nascart.com/electric.htm for how to cut a brush to increase the timing, what I call advance (and may be incorect)

This may also be a semantic issue, my definition of advanced timing might really be retarded timing.

Leading edge cuts = more speed

trailing edge cuts = more torque

advance, retard, whatever, the brush cut matters. If I read the other posts right, we are saying the same thing.

So why not square the brush. Cut both leading and trailing edges.
I used to do it on the old MVP's worked great.

Default stock

i used a stock class for a while and it had good power and speed, but was very sensitive to heat/ overgearing. one toothe off and it starts frying if you're not careful

I much prefer the monsters to anything else right now.

Anyone try any brush timing with the Camillion 2?
