Not too shabby ....

Big thankx to RMCompetition for the head work and cam design.  
My 557 SCJA head made 751 Hp @ 6000, and 726 Tq @ 4900 on Baker Engineering's dyno Friday.
First ever dyno session for me. Kudos to TJ and Co. @ Baker also.

You had better tighten up those sticks on the back.

That Randy knows a thing or two.
Was that a chassis dyno?

Baker Engineering, sometimes known as Pro/Cam racing engine components, has had an engine dynomometer for at least 30 years.  I think it is a Stuska with a DePac acquisition system.
They build and maintain quite a few Oval track race engines there.

I think they may have added a chassis dyno, also.

From the pics of it it looks like a dinosaur dyno. Is it common to pull an engine down in place of ramping up in RPM? Seems they go to full RPM then pull it down.

Their chassis dyno was a nice set-up. I was there when it was first installed and was a bit hard to get a good read on a front drive turbo car with a FMIC. They weren't set-up to give me any cooling.

With a Stuska dyno and DePac data acquisition system you can go up or down in the RPM range when testing an engine; whichever you wish. Pulling it down against the absorber for a test will usually emit a bit higher torque number, unless it is step tested.

I look forward to seeing you at the Memorial Shootout in early June.
