Overthinking x1000 here. Time is plenty accurate enough
Well, the pulse pumps push a given volume per cycle, so an integrated counter would be the simplest approach, but of course, I donāt see the pump makers jumping on board, more added cost & no revenue gain for the effort. Perhaps something thatās in line with the pulse line itself.
Im not so sure actually. For example, isnt a KA putting more wear on itself at 16000RPM than at 11000RPM, but its not making peak power at 16000RPM? Fuel usage might not really correlate to the wear and heat cycling that a motor goes through. I wonder if an RPM histogram is really whatās needed, that way you get time and RPM.
It would (not sure if RPM accounts for load bearing & how that might factor into wear, since running x RPM on the stand wonāt consume as much fuel as when carrying the weight of a driver on a track), but TM specifies rebuild schedules based on consumed fuel volume.

Keep in mind TM comes from a motorcross/enduro background, where you use a wider RPM band so it made sense to measure in liters, and I guess they kept it ever sinceā¦itās pretty much the āeuropeanā approach to measure it, I donāt recall measuring anything in hours until I came over to US, nobody used a hour counter. We simply kept track of how many 10L fuel containers we were mixing/using and thatās about it. Every 6 you do the top, every 12 top and bottom, as a baseline (KZ). For karts, as you are always close to max RPM it makes little difference, even the old schoolers that now use a hour meter, they simply convert hours to liters using a 10/11 conversion rate (KZ), keeps things very simple
Liters are easy to count if you only have one engine!
So itās probably just simply owed to European convention then, since the Japanese manufacturers use runtime hours.
I donāt think 10/11 would be accurate for TaG-KZ due to the different state if tune; would need to log hours & fuel consumption to establish a reasonably accurate ratio.
I see that it is the old exhaust on it with flex and a sleeve. Maby want to consider changing that before you start going all crazy at the trackā:+1:

Is blueprinting the same as ārace preppingā? I see some mentions of comet and I know other engine builders use the term race prep, which includes dyno validation. So curious if the terms are use interchangeably.
I would say in the case of kart motors, yes. Blueprinting isnāt really what is going on as the tricks that used to be used in true blueprinting are not allowed. So motor builders are looking to get the most out of an engine using the allowed modifications and there is a target they are looking for on the dyno. In other words, race prepping, so that when you put it on the kart, it is broken in and ready to give the most performance.
