Well, it's not quite what the spec records are at Hallet, but given how the car was setup I think I did pretty fair... 1:36.9 was the fastest... had about 6 laps in my last session that were under 1:37.3..
(FM DP, enthuza XR, 9psi, 205/45-16 V700s)
FWIW, the MSM cooling system doesn't handle a track day well on it's own.. 3 laps at speed, then one cooling lap were pretty much required to keep from pegging the temp needle.
There was a SCCA T3 setup car (rented for the day) running about 1:39-1:40 on 235/40-17 RA1s.
