Thanx.

Hey Erik, are you comparing the CFM & Glacier on that?

Thanx.

My foot never slipped off the pedal. I think the dips may be from when Erik was applying the load. just a guess.

Of course the run where the foot slipped also shows the best gains, and it would seem to me that the dyno operator would make another run if his foot slipped off. Something doesn't add up!

Umm, no. The lower HP run (without the large dip) made the GDP look even better. We didnt use that run because it wasnt close to numbers that JP had run here in the past.

We are only doing tests like this to see what really works on trucks with the mods that so many of us have. There is no ulterior motive. If it doesnt work, I dont want to carry it. If I sell a bunch of manifolds, that is cool, but I doubt I'll ever see as much margin from these sales to cover the time and effort involved in doing these tests. Nor will it make a dent in the $60k invested in the dyno equipment.

So what exactly would my motivation be to mislead anyone?
