Default REEDY MVP STOCK

Why do these motors run so bloody hot??? I have the right rollout/gear ratio for my track. I'm still using the standard springs that came with the motor, i've cut the comm but i don't think this would help. I've even installed a fan that blows air over the comm but still runs HOT. Any help would be appreciated.

Cheers
Mick

The MVP gets hot no matter what you do to it. Short of telling you to buy a new motor (Monster stock or ROAR Stock), I don't have too many suggestions. It's never been a fast or efficient motor.

I have used the motor with success on small, tight tracks try narrowing the face of the brush this should help.

Narrowing the brushes on this motor will make it run even hotter and make gearing absolutly crutial. Even when geared perfectly with narrow brushes, the motor runs so hot it will show a considerable drop in performance less than half way into the race. To get an MVP with narrowed brushes to work, you have to use the dry-ice trick or the peltier cooler before the race in an attempt to make the motor as cold as possible (without freezing it). Even with this method, it will still come off the track incredibly hot but you will only notice a slight decrease in performance toward the end of the race if you notice any at all.

I spent a long time getting this motor and brush combo to work and with a lot of help from Big Jim and Paradigm Racing (they cut brushes fspecifically for this application). While an MVP with narrowed brushes was faster than an MVP with full faced brushes under almost all circumstances, there was unfortunately no instance where this motor/brush combo was faster than a Monster Stock. And the Monster Stock is 1,000,000 times easier to work with.

Bottom line give up on the Reedy and go with Trinity or Epic based stock.

The problem with the MVP, is the motor is too good.....

Let me explain.
On the dyno (and no not the fantom dyno, lol) this motor produces very consistent and big power. Much more consistent than say a MOnster or Epic Roar stock will. The problem lies in the mangets. The magnets are way too strong for Stock racing. It cuts down the RPM and heat builds up very quickly. In turn heat = lower laptimes.

Believe me if you could get the heat out of the equation and pick the RPM up about 2000, this would be the motor to run.

We had to run them at the Oval nats this past spring and the TQ was about 2-3 seconds off the track record set with an EPIC Roar stock. So they can run pretty quick if you fool around with them but we figured if we ran Epics or Monsters we would have gained about a lap.

"The magnets are way too strong for Stock racing" If this is the case, then is there no way to De-zap the magnets to reduce their strength?? Jonathan

Some have tried to reverse zap the can then zap it normally again. This does increase RPM but usually the power loss is too much. At least for Oval it is. Not sure how it would work for On Road.

i've been out of the stock game awhile and so i run the monster just to keep the motor equation out of me trying to get back into the groove. but when i was doing well, i would experiment with my MVP...

i used narrowed brushes or full faced brushes with a drill hole. both worked relatively well and better than a standard full face brush configuration. i found that at least on fast high speed layouts where you barely roll off the throttle, it was very fast... its definitely a screamer on the straight, if you can maintain infield speed its a goodie.
