What is a good pinion size and what is a good range of pinions. Meaning like between 17 through 23 or something like that

I run an 18 tooth pinion on my P2K2 with a 88 Spur. I would get a range of 17 - 20 and that should get you going just fine.

Josh-Help answer a few questions and I will try to help a lil more.
Is it a Stock P2k2?P2k2 Pro?
Or is it a P2k2 Tuned by someone?
What color springs are on the motor?


Are you running the Red Spur?

Is the track REALLY BIG and FAST or is it kinda tight?

Answer these questions and not only can we help with gearing but maybe even a better Motor Brush/Spring Combo.

Depending on the track size, start off real low (13-14) and go by your run time and motor temp. Since trucks have a bigger tire than a buggy you have to gear down considerably lower.

Here is what the track consists of. You start out with about a 75ft straight away that ends with a 2 spaced apart singles then you have a S type turn with a small double that is followed by a huge set of doubles. Then you have another corner that goes into a rythm section with about 8 bumps. Then another corner that is followed by a big tabletop. Then your back at the start.

Here is what Im running now.

Truck: MF2

Motor: Team Br00d P2K2 pro

Springs: Purple Pos / Blue Neg for the rpms ( started out with red/green combo but I would get smoked on the straight)

Spur: 86

Pinion: 18

WOW -Is the Blue Spring Extremely LIGHT in tension?
Most blue springs are and I would pull it off right away.

With a 75ft straight that isnt much at all and I would actually gear the motor for the LONGEST PART of the track which is the infield stretched out.

If that blue spring is LIGHT like most manufacture's blue springs pull it out as fast as you can and either go another purple or a Red on the -.2 springs that far away can only mean brush bounce on one side of the motor which is really bad.
If you run purple/red then I would stay at 18.
If you run Purple/Purple you may try 18,19.
Red/Green works REALLY good in buggy on faster tracks but trucks dont seem to like the Green Spring on the -.If the BLUE spring your using is normal and VERY light in tension while it may feel ok I guarantee the motor doesnt like it.
Goodluck and if you need any other help just ask.

P.S.Great Choice in Motor's going with Team Br00d.

so you think I should run a little bit stiffer spring on the neg?

what about purple green

Driver1

our track is similar in size...

i would start with full face 767s with the red+ green- combination to start at..

i gear 16/88 and my truck always runs barely warm...this is in the winter also..
but also try and 17 and see what the affect it has on temp, punch out of corners ect....


try that and let us know...
