i like to run a 8.5 ratio on a monster and a 7.6 ratio on the p2k2 pro! keeps everything peaked when ur on a sweaper where everyone else is boggin but at the same times gives you the speed ya need!

Pops.... I never got Putnums to work for me... the comm always looks bad after I break them in, no matter how I do it and my dyno (or the track) doesnt show any increase in power. I know some guys swear by them but I just cant make them work for me. I still have my best luck with 767's. I also get my best dyno numbers and lap times with a purple spring on the pos side. I know you dont agree but it works for me.

Monster gearing = 6.0 to 6.8

on 99% of the motors i tried...the 767's had better luck in the Monsters then the Putnams....i didnt like the Putnams when i tried them they seemed poochy for me ....but thats my opinion

This is very intersting. Saturday for the first time, one of my Monster's (Brand new) would just not run with the Putnam brushes. I re-cut it and everything trying to get it to run, but it was slow as heck. Put some brand X brushes (didn't know what they were) and it ran much better.
Now, why is this? Putnams react the exact same way in Motors that have softer Copper in the Com, but Trinity stock Motors have always had a harder Copper, so Putnams worked very well.

I gotta wonder, is it the Com material in the Motor that is different or is Putnam using a different compound in the latest batch of Brushes.

Anybody have some idea's?

Thanks,

I have noticed that depending where you are, Monster stocks are geared all over the gearing spectrum.Here where I live ,we gear them at about between 7.3 and 8.0 or higher because we run on tracks that are medium sized .Where I noticed some people that run in australia have said they have run as high as 5.8 but usually around 6.0-6.5.My motors would fry at that gearing for touring car.Am I missing something here?Are your tracks that big that your constantly on throttle?Just wondering because the monster is a rpm motor.Anyone ?

i just ordered some putnam greens
for my monster stock

o-well...

why why why????

racenut123 - Ele racing on nitro sized tracks = high gearing.

I've run from 5.8 to 7.2 with my Mvp, it depend's on the track.

I've been checking the amp draws on 3 of my monster stocks. It seems like the newer one is drawing 7.8amps on a constant 4.0amps feed. The other 2 with a fresh cut and brushes are drawing 4.5-6 on a constant 4 amp feed.

I've heard that a good motor draws between 7-7.5. Now are 2 of my motors bad? I've tried all kinds of brushs and spring rates on the 2 lower ones, and still can not get it up to 7-7.5 amps.

These 2 motors had only 3-5 cuts on them. They do feel slow also on the track.

Hey george.What brushes are you running?I noticed with 767 over the stock trinity brush which is the cross cut 99's 4505? the amp draw is alot better with the reedy 767's. 4.5 amps at 4 volts is not much.I would have to hear the motor also.My motors with 767's at 4 volts are pulling anywhere from 7.5-9 amps.I dont know if testing this way is really accurate.I usually only use it for reference between motors.It helps is knowing how to gear my particular motor.Too many variables to be that accurate.Anyone else on this subject have some insight.

Hey POPS !! th brushes you gave me to try were ok on the bench but in the car on the track then went away fast.. like 1st lap any way thanks and Ill mess wit that motor later..

Hi everyone. Can you post your gear ratio for a medium sized TC track with a P2K2 Pro? Thanks. I find finding the gearing is a big hurdle.

I ran from 1.2 to 1.3 inch rollout on an xray with a p2k2. This is a bit on the high side. Next Sunday I'm going to try 1 - 1.12.

Although my p2k2 looks almost identical to a monster on the fantom dyno.

Hi guys,

do you know if there is a powerful 27T motor out there that comes with a full armature ( unfortunately split armatures are not allowed anymore ).

Thanks,
