lathe, dyno question
i now am ready to look for a lathe and a dyno. my question is this. which dyno to buy which lathe to buy and how important is a diamond bit? i like the trinity moster dyno, and i like all the lathes, is ther much of a difference, don't they all do the same thing?

Here's my 2 cents:
The diamond bit is great once you get used to your lathe. I wouldn't buy it right off because sometimes you have the odd "accident" while cutting motors. Once you're real smooth with the lathe, it's a great thing to have - never gets dull and the finish on the comm is great.
Dyno-wise, it depends what you want to do. If you're looking for a tool to break in motors and so forth, the Trinity dyno will work. I would also look at the MuchMore Motor Master. It works well too for that sort of thing.
Dyno-tuning is a whole different can of worms. You can't do much with any of the free-wheeling dynos that don't have any load on the motor. That's a completely different thread though, so I'll leave it at that.

basically i want the dyno to tell me when my motor starts to do what?
i know i am never going to dyno tune since i get to race about 12 times a year.

Basically, the free-wheeling dynos are going to give you the basics - RPM and Amp Draw. You can use this to do a quick check-up on your motor in-between cutting the comm and/or changing your brushes in order to determine how much your motor has fallen off from where it was right after a re-build.
Where I would draw the line though is in reading too much into the performance numbers. You can tune springs, brushes, etc. in a way that makes those dynos read much better numbers but this may or may not translate to improved performance in the car. For that, you need a more complex dyno that puts a load on the motor during testing.

There's a ton of opinion out there about what's crap, but I haven't seen a lathe or dyno from any of the major companies that totally sucks or anything, so I'd say if you stick to the fairly well known brands, you should be ok.

But just keep in mind the BEST dyno in the world is the track.....
