Took the 55 to TWS today and ran it for 15 to 20 minutes (yep 4.5 hours round trip). Ran perfect. Only difference in the car from when it bent the intake valves and melted the plugs last Oct. is the fuel and two steps colder plugs. I have no idea what octane was brought to me at Hallett that we put in the car after R4 then loaded it on the trailer but I know it had 93 in it today and it ran perfect. Last Oct. it messed up by T6 on the second lap first session out. I hate that it happened but hope it was just low octane fuel and not a problem waiting to return.
