George,
As always "Great stuff" and I'll be thinking of you as you run!
That you have a connection from the filler neck back to both cam towers and separate breathers to catch cans is rather interesting- seems counter intuitive but hey if it works it works. That you did not see a drop of oil in the catch cans is quite something- sounds as though the gases are in effect being "pumped" [pulsed might be a better word- hot gases tend to rise] into the cam tower which in turn [it would seem] helps push the oil back down the cam drain chimneys- no excess oil in there no blow to the catch can. Any excess pressure [we must be talking minimal amounts here] then blows through to the catch can and as the gases cool water vapour [combustion product in the blow by gas] then drops out as it cannot condense in the engine due to the heat inside.
It will be very interesting to learn how much oil you use during your run.
Let's hope the race conditions replicate the dyno session and possibly back to the drawing board with my efforts. I have nice alloy catch can lying around somewhere! At the moment I use a spent water bottle [& catch nothing]!
Regards
Fred

Matt,
The hood insulation is removed and vents added to the back of the hood.
You probably already seen the write up ( http://928.jorj7.com/wk-hood/ )

I have noticed that my engine temps where a little lower around town with the vents. Don't have em anymore but may go back to them.
Good luck again Bud.-Matt

I think you've been going to the wrong restaurants in China...
It's suppose to snow there tomorrow. Maybe a chance of rain next weekend.

For me one of the great moments of this event is just after we went thru the speed trap at 210
George mentioned to me in a very casual manor that he was off the throttle and the car was still going 195 and not wanting to slow down. As a passenger the car felt as stable as rock. The sound of the motor at that speed is a wonderful drug. Having owned a few 911's I couldn't imagine going this fast in one.
My only issue with the event was I was wearing Bill Ball's helmet and it's a size to small and I couldn't read the notes all that well.

Bill and I decided not to go to the NORC this time. With the work we still needed to do and the rain and snow up in Ely and Lund we figured it wouldn't be a good time to race. We're planning to run again in September at the Silver State Classic.
