Dynomomonometer question
Do any chassis dynos read the low end? I see most of the mags and some posted here start at over 3 grand.
One mag did a tune up on a 327 and it went low to around 2500 but not all the way down.
Seems to me that I'm driving around in the zone they don't ever mention.

Chassis dynoes will record any rpm the operator chooses. With automatics you have the problem of the tranny downshifting if you floor it at a low rpm but with a manual you can dyno it from idle. When I dynoed mine I did 1500 rpm and up.

It usually doesn't make more power than a good carb but drives better. I probably should make some more dyno pulls and see if I can best the carb numbers. I may if I tune it to the edge.
