160.3 mph with the small early stock GTS splitter. The nose seemed fine.
We had no issues on the banking or braking/turning. Of course, we were on
banking and. It going 160 mph around flat corners at Daytona.
We are on 8 inch fronts 10 inch rear wheels with 225/15 front and 275/15
rear Hoosiers R7.
I saw my prior email on engine failure was inconsistent. The surge in oil
pressure made us think main bearing. Then, the rod end cap bolt banged out
and sent the rod end/cap through the oil pan. I will update when we get
back. The bottom end had not been updated from our prior builder.

Thanks, Will.
A bad day racing is better than any day in the office, especially in
a rare car like the Pantera.
BTW, the Pantera had one timed session....best lap was 2:11.0A with
theoretical best (based on sectors) of 2:09.A We may with a few
more sessions got a few more seconds off that.A We would not have
gone faster top end than 162-63 as we had the rev limiter set at
6100 rpm and we're already there.
