Chassis dyno questions Options

[Cevan]

I want to mazimize the tuning of my carb'd 2056. Short of seat-of-the pants tuning, I figure using a chassis dyno is the way to go. I haven't checked to see where the nearest one is or how much it will be, but after spending all this time and money building it, I'd hate to leave any power on the table. I'm just not sure how you go about using it to tune the engine.

I assume I should have the engine pretty well broken in and running well with the carbs jetted as good as my seat-of-the-pants dyno can tell.

Do I go there with a variety of idle and main jets, air correctors, venturis, etc and start swapping things out one at a time based on a baseline run?

Keeping the stock HE's means you will be leaving significant power "on the table".
In addition to the variety of jets etc, you would need to bring other exhaust systems. You need to be prepared to change ignition timing to look for performance gains too. That means lots of dyno pulls with time between to allow the engine to ccol back down and to make your adjustments.

A much better way for you is to invest in good instrumentation and find a place to drive the car where you can experience a variety of rpm and load conditions including high speeds at WOT. You'll also need a good co-driver to keep an eye on gauges while you drive. Imo, instead of tuning for max power you should be looking for a balance between performance, fuel economy, and longevity (ie, keeping the engine cool).
