Charliesauto....that Bosch alternator at $2,500.00 is one more reason it cost a small fortune to build a competitive NASCAR engine. :shock: Mark H

I believe many of the teams of switched to an alternator manufactured by McLaren, not sure what kind of price those are.

Warpspeed, is that similar to a pull you guys would do at HMS ? What i am wondering mostly IS, would the pull be that slow and long ??? Also, is that way of pulling an engine typical of an inertia dyno ??? Thanks Mark H.
What was the purpose of the dyno test? I simple test to get a torque / HP curve should take less than 10 seconds. With the programming that can be done a longer test could be minutes, hours, or days.

Stan

This is s dyno test from the Carb Challenge which was done on the BLP inertia dyno.

It's a Prius engine, with the optional 9 volt conversion. Seriously though, I enjoyed watching the video.
I used to be a people person, but people ruined it.

How is the blow by figure calculated/measured? If we have a figure on a fresh engine dyno run, then a 500 mile race and dyno it again how much difference would we see? Is there a certain percentage from a fresh build that signals a significant performance drop?
