1, I got a used T1Evo2, and the spur saids 125 on it. Does it mean it has 125 tooth?
2, I heard people talk about 128 pitch, 64 pitch, 48 pitch, what is that??
3, I saw Josh Cyrul's gearing at some race and its 93/30, thats 32 tooth lower from my spur gear!! Can this be right?
4, Now if I am to stick with my 125 spur, approximately what pinion do I start with for a 23T stock at a medium grip asphalt technical track?
Thanks in advance
1. Yes.
2. 128 pitch doesn't exist. 64 has smaller teeth than 48.
3. Josh is probably running 48 pitch gears, while you have a 64 pitch gear.
4. No idea, sorry!

I have NEVER got greens to work in Reedy,Atlas,Corally or TOP Cans.Reedy 767's or a 767 and a 766 on the negative cut down works great.Are you doing something else?They dont close to the RPM in these motor's as 767's do.Now on epic cans they are hard to beat.
I have a TON of these motor's O.E.M style in the FS section if anyone is intrested.
I do like putnam greens, alot. Reedy 767's are good too, I just use what I have. I won several races with it against a Factory guy from fantom, and a bunch of other guys using monster stocks. For our track it worked well. I even gave it to someone else to run and they liked it alot. Maybe I just got a really good one?

Ahhh thanks! In this case, what is the benefit of running 1 pitch over another?
Thanks!

64 offers a wider choice of ratios, is potentially a bit more efficient, but is harder to mesh and easier to strip gears.

48dp is my choice, still lots of gearing options, and easier to use - it's the choice of many world class drivers as well.

With 64 pitch you can make small ratio adjustments with pinion changes alone.

Using 48p gears, you really need to change both the spur and pinion to get the same level of fine adjustment. Not really a problem in most Belt drive Cars. Shaft drive Cars require more work to change the spur, so some Guys prefer to use 64p.

I guess it depends on how serious you are about your racing. I true my motors after every race day, which is about 4-5 runs. I also don't pull the brushes or spray the motor with anything during the day. I just clean it with compressed air and re-oil the bushings. The comm seems to stay cleaner and the brushes stay seated.

Dyno stats vs. performance under racing conditions are way off

i never had any problems with any of the other EPIC based stock motors by Trinity, i followed the instructions on gearing when each new one came out and they worked great.

brushes i tried TRI 4499P, AE 767, HPI Sprints, (full width & trimmed) and even changed brush hoods to stand ups.......no help

wish you better luck, i'm sure you'll post if you come up with something
and of course yopur gonna believe trinity?
especially now the using the fantom dyno?
hhhhhhhmmmmmmm

The mvp is a great motor, I run one and it absolutely screams. But it has an on going problem with the magnets falling out. I've had two blow magnets in the last two months. When I re-buy I'll probably be getting a monster stock. The monster stays a hell of alot cooler and doesn't have the reliability issues. But if orion brings out a stock version of their new revolution, I'll definately be getting it.

i use a MVP based motor, but have not had to compete against any monsters yet.

Is the monster a better motor?

Fatdoggy-Durability issue's with Reedy over Trinity?
Your kidding right?
You may have got a couple of bad mvp's but there is NO WAY that trinity has better quality or durability.Run a trinity motor HOT 5 times and talk to me about NO Magnets.lol.
Sorry that you got a couple of bad one's but I have in the last 3 yrs of racing heard of 1 MVP having bad magnets and in just a year of monsters about 50.Plus the Reedy,Orion,Atlas magnets are 10x's the quality.
MVP's are great motor's if you know what to do with them.Even when they get hot they dont loose power.They just get hot.But if you drill the brush or do the Mike Reedy Trick they work Awesome on small to medium tracks.
Otherwise Im all about P2k2's.Monsters work GREAT on fast flowing tracks but when it gets tight?
No thanks.
James-It's a better motor on a FLOWING fast BIG track.The MVP will have ALOT more pull from the corners.
If you race on a small,medium track and wanna go trinity go P2K2.

I had no idea that the monsters had reliability problems. As I said before my mvp's were very fast, until the magnets fell out. I used some jb weld to stick the magnet back in earlier tonight, hopefully it works. Looks like when I replace my motor, it'll be a core stock or another mvp.

Thanks for the heads up.
