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. |

Sounds good to me! Make sure to have all of your tools and such with you, to make sure nothing goes wrong. (And remember, if it does, it'll be the one thing that you left the correct tool at home to deal with!)
Keep an eye on the gauges; with less air flowing over the car and more friction in the motor you may have a heat issue. I say do the 20-minute cam break-in at home, then head over to the dyno shop! --DD |
