Default Waffle pattern brushes/Dyno Questions

Anyone tried the waffle pattern brushes on a P2K/P2K2.

If I buy the Fantom Facts Dyno, what else do I need to buy to hook it up to my PC.
What features does the Fantom Dyno offer over the cheaper Indi Dyno. (besides PC compatability)

Thanks,

Pops: Never tried the brushes. Fantom, comes with all the hookups. You just have to register the sw with Dave C to print data and make changes. The indy dyno is not a "true" dyno. On the Fantom, look at the table results and not max numbers. Stock motors run between 20 - 28 amps. Tune in this area. I use a TD45 now so that is all I can offer. Sold my Fantom this summer. I use Tribo. Had good luck with them. JMO I put a drop of oil on my shims and use a teflon on both ends if possiable.
psycho is right not to tight. Had someone here at the track do that this summer. lost power due to drag and less rpm. Removed extra shims and motor came alive.

I bought a Fantom dyno because of the instantaneous data that you see in the table and the graphs are pretty too! It works well as a tuning aid. You can see small changes that you wouldn't see on a T35. I decided against one of those dynos that you have to do the math to figure out the numbers because you only get the peak data.

Default So whats the best dyno for the $$$

My P2K2 is apart for a skim cut, so I will recheck the spacing. I haven't been spinning the arm to check spacing, but it seems to find it's center ok without. I will try spinning this time.

So what is everyone's preference in motor dynos, that are available in the USA?

Thanks,

in offroad, i think that if anything is geared right it will work vry well. lately my favorite motors in a truck have been core/hellfire (TOP tear down). in a buggy i think almost anything on the face o the planet will work. p2k's as well as any other, and they take the abuse well.

Default Motor Problems?

Ok guys, I assembled some of the motors I posted about a few days back. Some are p2k's and some p2k2's. I ran them in on a 4 cell pack with 767's, red + green - and there was a lot of arking on the 3 motors I assembled. The arking did get less at about the 3-4 minute mark but it was still noticable. I took the motors apart to check out the comm and it looked pretty bad. No discoloration or anything but it seemed as if the serations on the brush dug into the comm and caused a burn like mark on the lines that separate the comm segments. Also, the serations in the brush were almost completely gone. I believe I had to cut about 1-2 thou off of the comm to get them clean again. I am assuming this is not normal? Anything I can try to fix the problem?

That's what happens with silver brushes like the 767's, they are hard on the comm so the serrations cut grooves.

It's normal - whether it's desirable is another question, I know trinity are releasing some brushes with angled serrations, which will wear the comm evenly.

I havent tried aligning the hoods yet. I was planning on picking up a tool next week unless I can get away with it some other way? Should I use another type of brush to align the hoods?

Default P2K(2) brushes

Everwhere I've looked. Almost everybody uses 767's in their
P2K's. That or another manufacturers similar brush & compound.
