Eric's cam challenge

But that was the whole point. The testing was to simulate what happens a good bit of time and that is get a cam, stick it in and go.

You’re old enough and been around enough to know that I’d say a majority of engine builds on this site not done by a shop (and some shops can’t degree a cam so there is that) get installed dot to dot.

I can’t believe it’s 2025 and guys still won’t spend the time and money to degree the cam. But it happens. A lot.

That was his whole point. I think he at least met expectations of how he set up the test. I’d say he worked his *** off and exceeded my expectations for sure.

That’s the beauty of dyno testing. You can set up about any testing you can think of. It’s not always about max power pulls (hang on…I have to throw up in my mouth a bit because that statement hurts) so you can test anything you think you want to learn.

I think it was @mbaird that put his engine on a dyno near him and they did very few power pulls. IIRC, and I tagged him so maybe he will see this and correct me if I’m wrong they spent most of the time doing part throttle work.

That dyno operator is rare. Most guys just start making power pulls. That’s ok but you can do more than that.

This is an example of setting up a test to see the results of just one change.
Yes… it was my engine . We did around 7 power pulls but spent quite a while doing low rpm/ part throttle tuning .
This guy was exceptional though… he had my engine for 3 days. Day 1 he hooked it up, Day 2 he broke it in and did some baseline tuning , day 3 we did part throttle and wide open runs for 6 hrs.
He charged me $650 if I recall .
