I had this all written out in one big report, but my email couldn't handle it
and I lost it. What just sent through the list was written off memory.
I don't have the information in front of me at the moment. I do remember
changes, but I'm not going to state them until I have the exact data as to not
confuse things. When it comes my way again (I'll hopefully have it for you
tommorow) I'll type it all up in a very detailed and easy to read fashion.
This doesn't apply to our cars but I'll tell you what the Porsche guys
have found and are running.
After Sat's Qualifying race, one of the Porsche 356 drivers came over, one
to compliment on all the nice saves from that sway bar incident, and another
to talk about the Hoosier Speedsters. This fellow started the weekend at
around 32lbs hot air pressure. With the recommendation of Vic Skirmants, he
bumped air pressures up until they were reading 37lbs hot. He dropped 4
seconds a lap with just this change. I talked to Vic later on and he confirmed
this is what they are running. Car weights are approx 1650lbs and negative
camber is -2 degrees. The tread also showed to be "rolling" a little more than
that of the Dick's Triumph. This is ODD. The lighter the car the lower you run
the air pressures, not so apparently with the Porsche's. Vic was running mid
2'19's to low 2'20's throughout the weekend. Looking at their tires, they too
were showing more wear in the center section than the outers, but I expected
to see more considering the tire pressures they are
running. BUT remember, these are a different type of car, with a different
type of a suspension.
As I said, I'll write up a nice report when I get the information. We have a
quick Spec Miata racer / set-up guy among our ranks; he was there and has ALL
the data at the moment, and he, I, Dick , and a few others are hard at work
getting these things exactly where they should be before the next event. The
Zippo GP should be interesting..

. Tires were reading about 31lbs hot, and the pyrometer was showing them to
be hotter in the middle than the outsides.

It is not clear to me what tire pressures you folks 'started with', and what
changes you made during the week end.
