If all goes well The Beast™ will be back in my garage by October 28th. Randal and I can then finish all of the little things and she will be ready to go.
As the motor is newly rebuilt with ZERO hours on it, I was thinking about the best way to break in the motor. Our engine builder has given us a sequence that he uses. Our first thought was to take it to the track and use the first 2 sessions to break it in. However, there is a risk that if we run into issues we will be far from home and have to deal with the inconvenience of coming home in the middle of the day. I have a chassis dyno that is close to me and gets $135 / hour to set up your car. The unit is programmable for the load on the car. I'm thinking this may be a much easier way to break the motor in. The dyno is located in a business park, so the owner says that 20 minute pulls are no problem. Two pulls and we should be good to go. I could then bring the car home, change the oil, and be ready for some fun! Anyone ever done this? Engine dyno's break in motors all time, so I don't see a downside. Any comments / experiences would be appreciated. Thanks, Bill P. |

Dyno Dynamics, Mustang, Rototest, etc all offer brake chassis dynos. This will allow you to properly load the engine at all load points. It will be fine breaking in a car on such a dyno. A Dynojet and many Superflows are inertia Dynos. They will not allow for engine loading. They only measure acceleration.

The one closest to me is a Dynapack 4000. Supposed to be programmable for load. Bill P. |
