Engine Dyno

There are a couple shops in the UK that use engine dynos.

Why are they preferred over a chassis dyno? Presumably there is some advantage. Any chance Buschur or AMS or the like is planning on getting one?

The guys on HorsepowerTV got one!

A nice little side effect is we could then see how a Mustang or Dynojet compares to flywheel power.

The benefits of an engine dyno is control.

You can control the load, the water temperature, the rate of acceleration, etc.

The benefits of an engine dyno is also repeatability and accuracy. You take the drivetrain/wheel-tire-roller interface out of the equation. They also use a more effective means of measurement by measuring brake torque and not observed torque.

You can measure at steady state, or transient states.

The list goes on for reason why an engine dyno is a better testing platform.

There are tons of engine dynos out there. You just have to find somebody that is willing to work with you to get the 4G63 hooked up to it. I know of a couple places that have the setup for the Subaru EJ motors and Honda motors, but for the 4G63, I don't know of any.

It's not compatible with the 4G63. They mentioned addressing that last I spoke to them. Not sure if they did...
