Rotary engine seals page 50 Sept 11

My old friend Larry Webster is wrong about the apex
seals. The current cast iron seals last
well over 200,000 miles.

The new Silicon Nitride ceramic apex seals
last indefinitely. Perhaps 500,000 miles or more.
No measurable wear.

Here is my 2004 RX8 smog report under the draconian California
smog testing.

Hi Larry,
