To dyno or not to dyno?

One of the biggest issues I run into is how much is the customer willing to spend, not only in cash but in time.

If you are testing a non roller engine where you have cam break in and spring changes and/or coated pistons that require time to break in you have to know you are going to eat up the better part of a day just doing that.

Thats before you ever make a pull.

If you want to really tune that is one full day at least. Even if you are using a computer and you can ride the dots to establish a timing curve.

Thats before you make a power pull. Thats before you start working on the carb or anything else. Of course you have your baseline tuneup so you aren’t killing parts getting to the place where you can make power pulls.

Two days is the absolute minimum to do that, and thats IF there are no other issues like oil leaks and who knows what else that can go wrong.

This is why guys aren’t always happy with the results of a day on the dyno. We haven’t even gotten into doing lash loops, carb changes, header testing or anything else.

Real dyno testing takes time to do it right and time is money.
