Tuning challenges of the latest trip.

[Ken]

I don't normally waste time dribbling about accomplishments at work, though figured this was probably worth a mention.
Been getting a few good tuning challenges this trip to Sydney, the latest was a Holden 6 running 3 x 500 Holleys that I converted to run on alky, turned out my bench tune was pretty close, with 9 pulls to level the bsfc and end up with a safe a/f.
Made 422 fw hp, took the throttle like it was a single 2 barrel carb setup.

The carbs after modding and re-plating.

I took a couple of videos of it running, though don't have a YT channel any more to host them.

A Rail.

That looks like the new HSD Irving head.

It's a Joe Zullo head.

Nice setup. Apart from alcohol whats keeping it cool on the dyno?

Other than the air pulled in from above the motor, not much else.
The block's been solid grouted, just have to keep the run time down to 5 minutes or less for the head.

Very similar looking though.

The JZed head is the old "Duggan" head.

This one below wasn't a challenge to tune, though definitely unique.
