Ive seen Xscream also do this to there intakes, the did tho fill the elbow a bit in the intake to straighten out and reducing volume in the intake. I use one of those modded boyesen intakes on my dasa 1100 wich i also reduced crankcase volume in, for me it looks like good results.

It will give you high rpms and a narrow powerband but power is power, it takes power (kw) to move water and you always have a correlation between power and torque thats just mathematical. My point was that no one in standup industry dyno anything and thats beacuse they say it cant be done, wich...

There is no need to pull long slow sweeps, thats only for 4strokes and 2stroke racebikes imo Dyno ski engines might not be for have it tuned, but a reference that is actually can produce this and that alot of HP the builder say they do. And yes you can fool the dyno with correction numbers and...

Well alot of them you do this on now, both water and eddy braked ones, Super Flow Dyno jet Go Power systems to name a few Its mostly up to you as a tuner/control of the dyno that limits what pulls that is possible/want to do

The correlation is that you will not have any pipe temp without load on the engine. 360 etc combos loads engine/pump way harder then some flips, seem to run pretty good :) I run rrp pipe now, with 100 jet in sprayer, temp a bit low but response is less if I go down to 85-90 in sprayer but temp...

Yes different curves for the engines, but hook it up to a modern dyno and use all the brake varibles you want you can simulate a jetpump/clutch, not tolkning about som old Dynomite Land and Sea crap. Yes the tuning will always be off a bit from when its finally installed in machine, but you will...

If it that SN with 760 and maybe 38s? Id start with 2.0ns 115g, 75p 135m, low 1turn, high 1-1/14 turn, just my 5cents, whats in it now?

Yes if you read it you see ive posted there, builders dont do it because people blindly trust them and buys stuff with hopes and Dreams, Yes they run good, but does a comp 900 pull 160+hp, and a new 1200cc around 200+? Naah i doubt it, but however they do run good.

You totally missed my point. But no a dyno test on a freestyle/freeride motor doesnt suck, it still gives you proof that the motor is capable of those hp that the manufacturer has promised, it can show the differences between exhaust system, it can help with finding sweet spots for ignition and...

Yes ofc chelminski, but what I mean is, you never or rarely get any hard proof of what power this and that makes, except for what you feel in your butt and arms. My hat is off for those dudes and companys that push this forward absolutly but everything in this buisness of aftermarket stuff is so...

Just in this way the standup pwc industry is quite funny, everybody talks about research and development in this and that, but when it comes down to a flow chart or a dyno sheet, nothing ever is shown or rarely done. I would love to see some engines and different carb/intake/exhaust setups...

Yes, and there is this second part of manufacturing a ready to run ski, you will have yo deal with alot of warranty claims that probably happens beacuse of improper usage/tuning/retardness, thats a quite bit to deal with, and that will fast cost a lot of money

Its a cool idea and market needs it imo, hopefully it goes well and its easy with spareparts and warranty claims. 12.500 sounds cheap compared to what every part of a standup ski costs as sparepart

If I remember correct white is more advanced

I would say pipe temp isnt everything to look for the amount of water also changes the resonance of the pipe, but that I guess you already know that

I would make cutback on it before going steeper

What prop do you have in it now? Do a clip on those 360/combos, you load the pump harder when comboing then just straight flips

Any clips of the ski ripping? Genuine interested in watching and hearing it run :)

If possible i always run racegas, i like how high compression wakes up a motor, and you can never have to much power

I'd say you better be prepared to do some glassing/carbon fiber work bo matter what old a/m hull you buy, even the rickters etc will be pretty worn from years of abuse
