Hyd roller?

Looking forward to the results.
Where will you be testing, and do you know what kind of dyno they have?

Freshly coated headers and the dyno usually doesn’t end well for the coating.

Correct. They use a SuperFlow but I'm not sure of the model. This particular shop has a bunch of Pro Mod clients (that win), so I go where the big dogs go.
