Mustang Dyno Results Ran 685/583 @ 6500 with 10 psi very consistently for about 12 runs, AFR was about 11.0. (Had some trouble with the boost controller).
Highest recorded was 718/629 @ 5000 rpm, but boost spiked up so we stopped the run early (again trouble with the boost controller).
Timing was set 16 deg for all runs, no methanol.
All runs were on a mustang dyno.
On the last run where the boost spiked, coolant sprayed out of the rad filler cap, and then we got off the throttle and shut it down, after which the car started and drove fine, no further runs were attempted.
What are the chances my head gaskets need replacing, OR is it possible the heads lifted "just a bit", due to the excessive pressure and reseated? I know I know wishful thinking, but i thought I would ask anyway...
