The motor will still heat up but the temp at the end of the run will not be as high because the intial temp was lower since the motor was iced.

I used the PEK2221 which is the standard stock motor brush, in an MVP previously(Narrowed, of course).
In Modified I used the PEK2151.
Both were pretty easy on the comm and lasted well.

For max performance in stock, the Reedy 767. It has the highest silver content. What I usually do is run a 767 on the psitive and a 766 on the negative side......the 766 is the brush that comes with the MVPs. This gives the same amount of power as 2 767s, but with less wear on the comm.

Also for max stock performance I also use Putnam green and blue shunt brushes. The green is extremely high silver and the blue is high silver. Run them the same way......green on the + and ble on the -

Hmm, got me on that one. I've never used Peak brushes. Although 99% of all brushes come from the same manufactuer, so just get the highest silver content they make and u should be set. So a high silver brush from Peak is gonna work the same as a high silver brush from Fantom, Putnam, Trinity, Lightspeed, Orion,Reedy,Birdman, ProMatch.........etc......u get the point.

Looks like the 2154 for Mod and the 2221 for stock.

I've tested a lot of brushes and as long as they are full face and high silver they WILL work....The Turbdyno doesn't lie!!

but they all use different oils to pull them out of the mold, different carbon make up. sure all the silver %'s are generalized but the rest of the compound is different

Well on the dyno they don't look much different. Maybe varrying a couple watts and slight variations in RPM which means nothing since thats mearly a gearing factor. Although where we race most of the people are able to tune their motors to maxx perfomance anyways, so the driving and setup are the only difference. I've won with motors that were having problems and OBVIOUSLY slower and still won so.............

What motor are u trying to tune? If you want a fast motor period, use Putnam Green on the + and Blue on the -. Red spring on the + and a green on the -. Make sure to have a fresh cut on the com. Never change brushes without cutting the comm first. Then run the motor at 3.00volts for 30 sec. pull the brushes out and check for even wear right down the center. If the mark is off u need to adjust your brush hoods. Once the hoods are set, run the motor for 4-5min @3.00 volts or until the brushes are fully seated and the serrations are gone.......now your set!

I suggest you align you brush hoods no matter what, then break the brushes in. Once you break them in, do not unseat them for any reason until your going to cut the com and replace the brushes.

I wouldn't recommend using dry ice or the like to cool motors before running, as it will make the bushings shrink causing a tight fit between the shaft and bushing IMO.

but also being the first part to heat up they will expand quickly that and most of us will either reem out the bushings on a new motor or use a tooth paste to burn away a little of the bushing and polish it.
