3" turbo back exhaust, self ported head with stock valves,
shift kitted auto, stock injectors, no AFM.

Just noticed that the IT is showing -77 on the graph.
Dont know what affect this would have on the final figure, if any.

Will put it on a dyno again in around six weeks (at a different place) with different timing & minor cam adjustment.

Did you have issues getting the ignition right when advancing the exhaust cams to +4 ?

When I'm at +4 I can't get below 12 degrees base timing.

I think something is wrong with my set of cams. It was from the first batch. The car has never run well since they were installed.

Just bought a set of HKS cams.

Hi guys I have the BC 264 cams in my motor and I'm almost ready for dyno.
Just curious. What settings are you guys running your adjustable cam gears at and what pin are they set at in the cam?
Also what sort of figures have you reached?
Cheers

Did you advance both cams or retard them?
