 At what RPM's Lynn?

 Paul Lamar

    The 12A gets it at 9,400. The street ported 13B at 9,200.

    I left a scavenge line too loose and paid for it today. The engine filled
with oil it blew out the breather catch can. The driver spun twice in
unlikely spots from the oil he was dropping, and it never occurred to him to
look at the oil pressure gage. It also has a nice idiot light. He went an
extra lap with no oil pressure. I did save the rotor bearings. I found them
in the scavenge filters. 

A fresh but old engine is in the car now and will be
running in the morning. Yesterday we hit the jetting dead on. We had 1600
degrees on both housings at 9,000 RPM. We make movies of the EGT and tach for
study after each session. It was interesting to see the rear housing come up
first. They both eventually run the same. I think the rear getting hotter
water is the reason. Mike Pinnigar is on the pole in a carbon fiber RX-3.
This may change Thursday PM when we have our last qualifying session. I think
Pinnigar must have close to 270 HP and he leaves nothing on the track. An
RX-3 ahead of all of the Nissans and Toyotas. It gets better every day.
