We dialed in another 05 F7 today, had 2 degree key and a D&D PAC.
For a 500 ft drag spec Chris made 150.5 HP at 40 PSI on his PAC gauge
(= 38 psi on my dyno gauge). Dropping pressure lower than that ran too
lean– dropped HP. These all really need to be dyno’d somewhere to be
sure if you want to tune fuel pressure to max HP. I will try to post
some of the incredible lean fuel bone stock hotrod results this weekend.
We’re dialing in two more F7s tomorrow from north of Albany NY,
at the same time our webguys are coming to install cameras in the
dyno–one in the control room, and one in the dyno room, both with
audio pickups. So if all goes as planned, you will be able to observe
the goings in both rooms while we hookup sleds on my dyno hydraulic
lift. Then you can see/ hear the howling of the engines while the
SuperFlow dyno accelerates the engines through the powerband and
records the data posted on DTR. I’m hoping that we can connect the
Superflow computer screen to the webpage so you can see, immediately
the results of each dyno run. We’ll know more about the ultimte
capabilities of the live streaming video by Sunday.
Now on Sunday we’re hoping to have our first consumer MachZ on the
dyno. It would be good to have that data before Monday when the SkiDoo
and Polaris SnowWeek/ DTR shootout sleds arrive for certification.
