Scotty and mindless make a good point I rode his 785 with dry pipe. It was nasty power. Nothing to do with cc but it was race fuel "perfectly setup" with God knows how much testing,swapping,tuning by the best builders in world to get it perfect with a pipe with no ability of sound wave adjustment. Same thing goes for mindlesses ski. Crazy amount of time put in with setup ect ect Quite a accomplishment with pump fuel really it's making great power. It's funny u mention rider ability though. If u ever tried injecting it for instant linear hit more friendly to learning tricks u may be surprised at your new ability with it

Its all in the tuning and what you want to do with it....... Harder Hit, Soft Ramp up of power. Arm Ripping Explosive power...... Each person may like a different setup.

I bet if we took a poll of what kinda power curve would you prefer? Almost all would put a check in the box for immediate maximum off idle torque and power that is linear through the milli sec you pull throttle all the way through upper mid and sac a bit of top end hp All but top pros. That's what injection timing the pipe wave provides. The same reason the b pipe was so popular for so many yrs before combo surf /flat water hull builds became possible

I have a boat you need to ride if you want immediate arm ripping power a d @bigkahuna can back me up. It's honestly in the pump tuning. I purposely set it up slightly under propped to demo the low end snap of the 1105 at wf. The prop before that changed the whole attitude of the way the motor hit. It had no other changes but propping it down. Out of 30 plus guys that rode it only 2 came back in and said it felt under propped lol. This boat will be in va this weekend @masterblaster hit up Erik or Phil to test it out.

I never want to set foot on that ski again. unless it has a smaller motor or you pull a plug cap off................ or both plug caps.......... Holy crap.

Brian216. I have no doubt that it's great powercurve. That 10 mill crank and 155 mag amoung many other things helps.
I'm just gettin at this. If I was a tuner makin $tuning to substitize my ski habit I may promote spending countless hours messing with exh mani size.stinger mods.Waterbox baffles. Ign timing. Carb jetting. Pump size Prop pitch. Reduction nozzle diameter ect ect. All to the perfect load on motor to deliver the pipe sound wave at the mili sec it needs to be to make dry pipe timing curve work well. Not to say All those factors cant be At least close and still have the pipe work injected. But it will be much more obtainable with more variation in other components just by changing water settings to time the pipe

Its not rocket science........... Well ok, yes it is. But you get good results with either setup. It is all just different methods of tuning and where you want your power to be.....

Seriously.... I didn't know running a dry vs wet pipe setup could cause so many different opinions. I thought we all had different boats and we could do what the F we wanted to it..... everyone has different riding styles and like the power in a different spot. I'm not one that likes to "wait" for the power when it comes to surf......

Part of the reason the wet pfp is popular is its easier to tune. The pfp takes a bit of work to get it hitting where you want. It's easy to bolt a pfp on and be disappointed with the powerband. After injecting the pipe you suddenly have a bunch of snap.

thats another way of saying it..lol after all we are talking about fractions of a second

You all have me so confused.. Why would you not want to inject?

Does the PFP camber design provide the perfect wave timing for every motor package out there? At least with injection you can tune the wave to your setup vs tuning your setup to the wave.

Dag, At this level. It is not just bolt on parts and go. With injection it does give you room to tune. With Dry, you have to tune a different way. Phil has the tuning down. I rode the new 900 on his ski at Havasu. All I can say is holy crap. I have never felt a ski that was as crisp. XScream (Chucky) and Tricky all know how to get the power out of the PFP in Dry Mode.

We are way past the bolt on parts and go, I don't think anyone that runs a PFP can bolt on and go. As stated early in this thread, it will be very disappointing. so moving away from that..

What i'm stating is why would anyone (other than top level riders, that have professional support and advice) not want to inject. Injecting allows you to tune the wave to the setup you have. If its a $8K boat or a $20k boat a spray bar cost what $35 and and withj $5 jetting changes you can tune to your setup. If you tune your boat to the natural wave of the pipe you are talking spending $1000 in "tuning variations" unless you can convince a "pro tuner" to give you the setup you need to make it all work from the get go.

My experience is you will never get "pro advice" here unless you are a 1%er

How are people controlling the injection? When I had it on my race limited SJ I had an MSD controller. There are other ways to use static control. Using jets to control flow but it is not cutting off the actual flow. I have also heard of using a FCV to help control flow also. That just blows your mind trying to figure out the plumbing on that way!

but to answer your question. If I was spending 5k on a motor, 2K on a pipe setup plus possible 2k on MSD Total Loss. 2K on a pump setup. Whoever I was getting the motor from would be getting hired to help get it setup also. After spending almost $12k on a driveline It is crazy to not pay a few hundred to get the final pieces of the puzzle put in place.

Why not try it? The amount of time people spend reading others opinions you could just test for yourself. You can drill and tap the manifold, and put in a spray bar for very little cost. Change the water routing and see for yourself. If you dont like it you can plug that hole with a npt fitting and put it back to dry. All for under $50 and a little of your time.
