Another item I thought of is the 8 EGT bungs my dyno headers have where my chassis headers only have them on 1 and 8.

I have adopted the habit of overbuilding my engines hp wise so various real world parasitic losses (or otherwise) are not the end of the world. And then we also have nitrous lol. I'll definitely make some hits on the chassis dyno to double check the driveline at speed. The chassis dyno available to me chews the hell out of slicks which is something to consider. In my world the engine dyno is money well spent just like a wheel dyno.

Also there is no way you can test power adders, verify valvetrain stability or accurately get a baseline fuel curve with a test stand..it's not happening. Also agree on using the carb and box for the car. No worn out pro power dyno mule coil for this guy.
