This is from Teammate Ray's '99 FRC with new 408 engine and our custom tuning during a 90 mile ORR on Nevada state road 318.
He covered the 90 miles in about 32 minutes.
He had the Ease datalogger record everything that went on for the powertrain and here is the raw data analyzed.

Average speed 168 MPH, top speed 195 MPH.
Zero misfires or knock even though this road was above 6,000 feet above sealevel which cost the engine 91 HP.



We did the whole tune via emails, I never saw the car and only went by Ease PCM scanner data to do a true custom tune.
