I would much rather put resources towards finding an answer to the age old question of: Do they still make those?" or "How fast does it go?"
Freestyle Who wants actual dyno numbers?

yup thats about what a 787 makes. Thats with the ve cylinder assuming you have the ve cylinder so 3 exhaust ports and 7 transfers rotary valve so we know they breath very well.

hope you have success with this,no reason it cant happen in fl especially. I talked about this in length yrs back and you could tell everyone was afraid of it. who really cares what the # is. the data is in the comparison. what ever is best is best and no denying it! power on the curve is great to know as well,give you a good idea of whos port timing is really working better for what we do

Yes thats right its not about the power its about who has the most and the best delivery.
But as long as bogus figures are being quoted then its just bigger and bigger to make it look better. so figures get based on the seat of the pants dyno
Peak numbers on a dyno are nothing more than bragging rights. It's the hp and tq curves that mean the most. As far as what you'll feel by riding if you would compare a engine that say has 120 hp and 85ft lbs of torque and an engine with 115 hp and 90 ft lbs of torque the engine with more torque will feel stronger cause it's easier to feel torque than hp

i like how the first 3 pages have people talking about how import tork is. now someone jumps in on the 4th page. boss i tell yous what. dis here moostang has tork. not like your rice patty over dere.

yeah, but throwing in a pump adds a whole new factor of uncertainty.
No it's not. The pump is the only thing that matters. HP on a shop stand is irrelevent. What matters is thrust, the delivery of that power. A motor builder should be as concerned with matching their setup with a pump as they are building the motor.
Who cares how much HP your car motor is rated for. They don't brag about how they pulled their motor and dyno'ed it. The brag about HP to the rear wheels. The power of the motor is only as relivent as that power delivery.
And in the end of the day, all of the talk is settled on the drag strip. Dyno's are for tuning. There are more practical ways to measure an engine. For example, how it performs. I guess the engine builders know that since they spend obsured amounts of money sponsoring riders.

One day out with my X2.
Random guy, "Dude, where did you rent that?"
Me, "Huh? It's mine. Why do you think it is a rental?"
Random guy, "On the handle bars there, it says Rental."
Me, "Dude, rental isn't spelled with an H. It says Renthal. It's the brand of handle bars."
Random guy, "Oh, dang, I wanted to rent one."

do me a favor. sober up and reread what you typed.
drag racing is gay. and i can't believe you just insinuated that a 650 motor with a perfect pump setup could compete with something else. seriously, the only way a stockish motor could compete with these motors is if you started in the water and someone else was on a beach cart a 100 yards away and the race was only 101 yards.
i think i see what you are saying, but, just like building a car. you pick a point in your setup and build for it. you don't buy a 14/20 prop and a 150 mag and go let me build my motor around that. you start with the motor and set your pump up accordingly. how much usable hp and tq is king. sorry.

comparing engines with pumps is a terrible way to compare engines.

ha ha... it got so bad one year that my friend put "not for rent" on his hood in big bold letters... guess what still happened...
I would really like to reverse engineer this whole thang Bros, What we need is to see what type of force is required to throw a ski and rider into the air 25', next see what load is required for a 148,150, 155 pump with all kinds of props to develope the thrust for the 25 foot goal,from 0 to 15mph , 0 to 7000rpm. Then "Dyno" hords of motor with different combos and see what may work best. We could do this for just a few hundred thousand , I think a federal grant for this nobel project is in order.
I like good throttle response and strong coffee Yee haw , Happy Thanks Giving out.

If you look at the snowmobile engines of equal displacement they're getting the 200 plus hp out of their engines but @ 8200 rpm to 9000 rpm, and thats using twin pipe setups. So how are watercraft getting that number at 1000 rpm lower and on a single pipe? I've done some dyno testing and you can definately fudge the numbers but it doesn't do any good if your trying to make improvement. For a good engine its all about torque and responce, and that responce comes from a good package ie: pump, ignition, engine rev charactoristics. If your screaming for hp numbers than most likely you don't really know enough about the subject to understand what makes a good setup. I'll take a good setup over supposed peak power any day. Oh yea, its gotta be tuned right to even make it worth the effort, and if you think "just give me the jetting specs" is what tunning is, you need to pay some one to do it.

What kind of dyno do OEM's use to proclaim their HP numbers?? I wonder how true those numbers are..
