Could we make a list over what is needed for doing the conversion from a 144 superjet pump to a 155 oem pump and what models that have these oem? It would be to great help for me and others looking for this option

Fantastic work, you got a lot of talent. Please don't over work so you loose your motivation. The sport is evolving due to people like you :)

I am interested if he doesnt take it ;)

Just to clarify for other readers, what I have said is regarding dyno testing complete packages to show customers what they can expect for the money. I did not talk about one specific component or whatnot. I do however like the tech info that have come out of this discussion, but I feel that the...

I have a question for the wise, how come that you say that no dyno can reproduce the load of a pump when it is easy to get a dyno with an electric generator as a load with programmable load curve/rpm input? It is totally possible to get a custom load from a dyno, but I accept that it would cost...

Since I have a DASA motor with a TNT chamber I know that they make good power and they also know what they are doing. But even when I know that I still think that having a way of measuring what kind of torque the motor produces is a great way of knowing what the different builders can do. It...

We are not talking strictly about a pipe builder but an engine builder. And he would have to do that once on each motor he builds to collect the data we need. He could buy the service from a third party testing facility and easily get away with far less than 45k$ But since most of you don't...

I don't know if there is a language barrier, but I tried to say that you should use a puller and not just bang on the crank. And when I re read my post it seems pretty clear to me at least that this is what I said

I was thinking about knocking the flywheel off the crank without any puller with tension mounted ;) That works too, but not without damaging the crank shaft.

The best solution is to use a flywheel puller. There are three threaded holes in the flywheel where you fasten the puller and pushes the flywheel of the crank shaft. Should not be a very expensive tool. Using a hammer is not recommended even if that does the job(poor crank shaft) Edit, seems...

Second the sheared flywheel key. I've had that happen with the exact same symptoms on a jetski and motobike

Do you have more info about this? I am in the process of making some custom stuff and need to calculate torque requirements for the pump

I understand that, but how does the need for different pumps for different motors void the fact that a dyno reading tells how a motor behaves? Am I missing a important factor? If I had two motors with the same torque curves. How would the two motors behave differently? And if one motor has...

Have you ever seen somebody mapping/finetune a car to program a ECU on a road? I just don't buy it, but you are free to do. Because someone with an agenda tells you something doesn't make it true. What power that the engine produces is not usable to a pump? Please give me data that proves that...

But that is another part of the driveline that needs to be taken in to account. That does not rule out that knowing how your engine perform is unnecessary? Let say that you have a brand x 1000cc motor giving y powerband on a dyno. The next engine builder provides another motor with the same plot...
