Now I know why you guys are so interested in the P2K2 - last night I tried my new P2K (1. gen) - much better than my Spitfire.

in my stable, i keep 2 p2k's and 2 gm3's. i've tried the chrome stock - good torque, but the p2k performs better and is more consistant. also had a spitfire - it's identical to the chrome stock, but my spitfire performed better than my chrome stock. i had 2 mvp's, but they still seemed a little lack luster compared to my p2k's.
i race atleast once a week, sometimes twice. i used to cut the comms every night i raced, but i've noticed that sometimes it would be completely broken in. now i my comms about every 11-13 runs, depending on how the comms look. i usually get the best performance between the 5th and 13th run (i define a run as a full a battery pack or approximately 5 minutes - the equivalent of a race).
i gear my p2k's pretty tall, and my gm3's considerably lower. my gearing gets more specific depending on how the track is set. all of my p2k's are real torquee - 183 & 184 nmm's. so you see, even on a tight track, i can only maximize it's performance if i gear high.
can't wait to get my hands on the new 2nd generation p2k, i'm thinking it'll be the new benchmark

I can't wait either.... I'm thinking about retiring my GM3 after I get one.

I ran the P2K2 motor last night and it ran great! Can't wait till real motor builders get a hold of this motor and start working their magic on it. Here are numbers off of my Competition Electronics dyno:

Here are the stock numbers straight out of the box:

RPM Torq Watt EF Amps
18098 4.3 58 64 13.3
16668 6.1 75 64 17.3
15782 7.2 84 61 20.0
15127 7.9 88 59 21.8
14279 8.6 91 56 23.8
13375 9.5 93 52 26.0

And here are the numbers after a fellow racer (sting) & I spent a couple of hours on the motors (this is the motor the way I ran last night):

RPM Torq Watt EF Amps
24941 2.4 45 50 13.3
22477 4.6 77 65 17.3
20543 6.2 94 69 20.0
19704 6.9 100 67 21.8
19080 7.6 108 67 23.8
18184 8.5 114 64 25.9

One of our local motor builders (acloco) is taking the motor and seeing what he can work with it.

The second set of numbers are pretty good. Too baad I'm getting rid of my dyno stuff. Acloco and I pretty much do the same thing to the motors. Good run last night. Too bad things didn't go too well for me. I'll be back out there for the last points race though.

i just picked up a p2k2, but it isn't a pro - no dyno #'s to look at. it looks similar to the original except the can is a different color. out of the box it's a pig. @ 4 volts, it wasn't pulling too much juice. anyway, i'm gonna have to mess with this thing and figure a good spring/brush combo. the springs & brushes it comes with kinda suck.

The ones we have at my LHS don't say "Pro" on the box, but they are the same price as P2k Pro... so my asumption is they are the Pros seeing i told the other guy to order "Pro" not the regular...

I bought a body today instead of motors..... so i'll wait a while on that..

The P2K2 Pro is not out. Only the regular P2K2 is out -- the Pro version normally comes a month or so later, and then Trinity released bulk motors to aftermarket tuners about another month or two after that.

I ran a P2K2 for the entire raceday today. I was also directing, so I didn't have time to true the comm or really do any other maintenance to it, but it performed well.

I started off with a 21/88 gearing (7.67 FDR) and moved up to a 22/88 (7.32 FDR). It seemed like I might be able to go up another notch (23T pinnion, 7.00 FDR) but I did not really want to risk trashing the motor in the main.

To those of you that have also been testing the P2K2, how far have you pushed it gearing-wise? I regularly ran my P2Ks in the 6.5-7.0 range, but after the GM3 debacle I don't know how far I can push this new one.

I don't know though, after a five minute heat with a 7.32 (22T on a XXX-S) you could still touch the motor for a bit. I bet Jeff G. was geared even higher than that, he was running a P2K2 as well and definitely had speed on me in the straights.

Nobody killed a P2K2 today, but Tim smoked a GM3...
