Tuning challenges of the latest trip.

Postby Ken » Fri Jul 19, 2019 1:57 am

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.

The carbs fitted.

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

That looks like the new HSD Irving head.

It's a Joe Zullo head.

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.

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