Welcome to the IHoP

Now is that total unit weight or rotating internals weight?

Either way I say you are putting way to much work into pissing into the wind on figuring that.

Also need to know the radius & balance as well. I also hope this is the drive side as any calculations will be dominated by losses in the CVT itself. *basically saying the same thing R2 is

They still have the Ono dB? If so, my bet is that if you Macadamia/Panko crust it and cook it in a light pan of olive oil that the non-fish eaters will love it.

Unless it is fried catfish around here I will stick to something that walks on land till I find a place that actually has good fish.

pretty simple really: the best fish is as fresh as possible

Do you guys know how I could calculate the change in output of a system that has a heavier rotational mass component

Problem

State 1 Engine>CVT System>Transmission

State 2 Engine>Heavier CVT System>Transmission

When I say heavier we are comparing a 16 lb system with a 15 lb system. But because our engine is only 10 hp I figured it may make a difference

Or as the other guy on my team would say, "Yeah, it actually makes a fuck!"

Okay, I am lost. A CVT is a constantly variable transmission, so why the need for one transmission, then another? Are you driving more than one thing off the same engine and need to run one at a different speed? I don't know exactly what you are trying to accomplish here, but given the relatively small output of the engine, I'd just use a centrifugal clutch setup given you don't need to move more than 4-500 pounds.

The lighter setup has a lighter Drive but a heavier driven.

I'm trying to think of some ideas to really shave some weight. Possibility of resurfacing the sheaves a bit to reduce weight maybe looking into grinding away weight where it is not needed. Particularly in the spider or something.... hell I dunno

I guess I should have said a F-N-R Gearbox.

If you want to shave weight off of the car do it someplace else then grinding on the transmission.

Hydrostatic drive off a tractor. Should be cheap, easily attainable and not too heavy. A belt will be your mechanical connection, so service is easy. Some are a simple as a couple pullies and a belt. Can't beat that for weight.

What's the concern with the weight anyways?

If I haven't explained. I am doing a mini-baja competition where we build a single seat off road vehicle to take to a competition where we will do acceleration, maneuverability, suspension, pulling, and an endurance test. We are only allowed to use an unmodified Briggs and Stratton 10HP engine so creating the most efficient drivetrain as efficient as possible is a big concern as well as keeping the car as light as possible. And ofcourse rotating mass is always much more of a factor than static mass.

If you want to save weight. Run the calculations and do testing to see how much steel you need in the suspension and frame. Test the crap out if it. Are what breaks and what doesn't. What doesn't take material out of and need up what does break. Find a happy medium in there that you can live with.

Use heat treated chrome moly frame. Not just chromemoly get someone who can actually weld and make that frame as light as possible.

I'd find a hydro off a zero turn mower. Allows F-N-R and you get the extra maneuverability of the zero turn. Can't beat that. Speed and acceleration shouldn't be an issue. Don't know what you have to pull but it shouldn't be too much of a problem.

If I was on the team I would highly advise leaving the transmission alone unless you have the resources to buying multiple ones.

What materials can they use?

This is rather off the wall, but have you considered Bamboo? It's super light, super-strong, and should be able to take the weight of one man and an engine.

I know our naks car runs a cvt and a hear reduction box with a top speed of over thirty.
