You can make money with IF you run it a lot.
Plus it should be a business driver. Not only for your shop but other local shops to come to you.
You already know but I’ll say it for John Q. Public a dyno will protect you and the customer before the engine leaves the shop.
You catch leaks and other stuff. You are breaking in the cam in a relatively safe environment.
At this point, I’d rather guys spend two days on the dyno especially if they really want to tune the engine.
Not just lash loops but developing a timing curve and testing headers and stuff.
In a shop environment you really need a guy who can run the dyno and do the tuning, but who is capable of doing other work if the dyno is not being used.
And then finding people who not only want to do it but are capable of doing it, or at least learning to do it.
Learning to run the dyno is relatively simple. Learning how to use it is much more difficult.
Learning how it actually works, and what’s wrong with it when things get sideways is much, much more difficult to do.
