Rick:

We build high-performance Lycomings for a few select customers, and have
always used the B&C starter and linear regulator as an integral part of the engine
package (which also icludes an improved inverted oil system,
specially-designed cam, flow-developed and balanced heads, compression as high as 11 to 1,
modified intake system, special ignition system, modified injectors, tuned-length
headers, improved baffling, etc. etc. etc). As you might imagine, the
cranking demands of an IO-540 with 11:1 compression and a  lightweight MT prop are
pretty severe.

With the B&C, they spin almost as if the plugs were out.

(BTW, this is not an advert. We are swamped with work.)
