Reply to "air filter"

Dear Bell,

FWIW, years ago Space City Panteras hosted a Dyno Day. In their testing, the Holley Dogbone air cleaner was the only one that did not lose HP and, IIRC, actually gained a bit of power. I was surprised.

Recently, a friend had a 351C professionally built and dyno tested. He had a Holley Dogbone and I related the tale of the Space City findings. So, after the standard dyno test and tuning, the engine made 447 HP. Then dyno test with the Holley Dogbone in place showed a stunning 20 HP gain with the top end at 467HP. I was very, very surprised. The engine builder could not explain it, but did say that such unexpected phenomena happen once in a great while.

I think it is very interesting that the two dyno tests with the Holley Dogbone both show positive findings. My friend enjoyed the engine, Holley dogbone and the 4000 mile round-trip drive to the Fun Rally this year. There is *something* about those darn dogbones.

Warmest regards, Chuck Engles
