[Fot] 7-1/4" clutch and chassis dyno

[Scott Janzen]

So, I’m putting together my car with a fresh engine.  With a new engine, I almost always spend a few hours on a local chassis dyno - seat the rings, set the timing, check performance, play with carb jets, etc.  Way better than showing up at an event with adjustments not made or an engine that blows up on the first run.

Anyway, I have a new quartermaster 7-1/4” clutch assembly and flywheel that I would like to put in. However, I have to slip the clutch a lot to get the chassis dyno spooled up, and if I do 5-10 pulls, that’s a lot of clutch slipping.  Am I going to toast the new little guy?

The alternative, which is of course not very attractive, is to put the full size flywheel/clutch assembly in, do the dyno runs, then pull everything out and swap it. Basically an engine/trans pull, as swapping a flywheel with the engine still in the car and the transmission out just sounds painful.

Thoughts?
