Anyone mounted one of these engines on a flywheel dyno for tuning? Lots of work, but has it been done?

Edelbrock has one, and I would be surprised if DC or Underground didn't get one soon, or at least have access to one. Some of the trade schools have them as well.

yellowfever#154 said:I would prefer a engine dyno than wheel dyno myself. Easier to work on the engine, easier to fix problems or leaks, etc. Our builder told us that it is more accurate to tune on his dyno than a wheel dyno. When measuring A/F ratios they have a fuel flow meter and can tune to each cylinder easier (dont ask how cause I dont remember what he said). A similar process that they use on blown alcohol engines. When on a wheel dyno they are using only 2 O2 sensors and each sensor is measuring 5 different cylinders.

Naturally, if I was just doing a Billet bottom end/cam swap I would go straight to the chassis dyno.
