Of course if time allows and its feasible you would want more than one pull for each test anyways to confirm repeatability

Several companies like the concept and have been offering help. I’m getting the fueling nailed down so the car doesn’t hit a fueling wall before the Pure500 capacity. Fun stuff!

You mention maxing out and reliably in the same sentence. Don't think that is how it usually works 😉

Depends what you mean by 'max out'. Like is driving a car at WOT "maxing it out" and can you do so reliably? Is running your CPU on your PC at 100% maxing it out and can you do so reliably? Part of me wants to say you should be able to use things at 100% (i.e., 'max out') reliably if they are well designed; i.e., they would include a factor of safety so they they can run at 100% without truly being at their limit. But it's a somewhat subjective interpretation of maxing out. Some engineering and philosophical food for thought
