Good day on dyno with Jim.
Haulins sled/motor did good even though it had Quebec gas which was only 89 octane and 15c or 58f temps with humidity.

175 HP and 110 torque on a motor that was iantomasi build. The motor is Sooooooo smooth .

Even though the dyno corrects, if it would have been -10c or 17f with 91 octane . Less humid. This motor is an easy achiever of 180 HP all day long.

I'm really happy with the way Jerry and Flav did this this motor. The Iantomasi boys know their stuff .Div20

This wasn't just about the 840. I was testing getting pipe temps up too. Success there too. Got pipe temps up 100/150 without expensive components.Div20
