Video: Dinan BMW M49 dyno video makes me tingly

dinan bmw m49 engine dyno

Engine dyno videos are either exciting or terrifying. Well, OK, occasionally they’re boring too. The folks at Dinan just put out a video that manages to be amazing, sensational, and borderline pornographic. The star of the clip is a Dinan-rejuvenated BMW M49. If you know BMW engine codes, you know we’re dealing with something special here.

How special? Well, this is a M49/2, which was the motor used by the 1976 BMW 3.5 CSL IMSA… which won the 24 Hours of Daytona. It was rated at 480 bhp, which is a ton when you consider that the Batmobile-esque BMW racecars it powered only weighed about 2300 pounds.

Want to hear what one sounds like?

That, my friends, is a noise that sends shivers down my spine. Well done Dinan… well done indeed.


  1. Is this post working for everyone? I'm having issues with it on my computer… but the issues don't make sense.

    1. No video, and inexplicably, if I click on the link, it takes me to a different Hooniverse M1 vs. Pantera article. If I copy the link location, it does the same thing. If I take just the youtube part off the copied link, I get the correct, dead sexy video.

  2. What are the sprayers in the top of the Velocity Stacks?
    That sound is so very amazing. Also super cool seeing the slide valves in action.

      1. I don't think I've seen fuel injection above the butterfly. That's way out of the mind of a carburetor guy.

        1. I recognized it only because the injector's above the butterfly on the throttle body of my Geo Metro.
