Freestyle Running Powerfactor chamber wet

my experience with them was negligible cause i wasnt using the extra power up top it was providing and it was difficult to keep the pressure right,it would eventually collapse to quickly and cause the pipe to over heat. With some extra testing using a larger valve, a valve that uses a pretty large washer sealing surface works better.the larger the washer pushes shut easier,allowing for a much stiffer bigger spring to hold it open under higher pressures,a heavy duty spring is more likely to keep its original tension after being completely compressed for greater and longer duration's. You can also drill micro holes in the washer to allow just a bit of water through when the valve is shut to keep pipe from over heating and still keep in it the right heat and timing zone for sustained top rpm..I just never ride like that. but im sure some here do.

Interesting thread with many ideas on how best / reliably administer the water (MSD Water injection, reverse flow control valves etc)... Could I chuck another one in the mix having had a think?

Yam made the YPVS (electric power valves) and Seadoo / DASA / XScream realised pneumatics driven off crank pressure would work far more liner and reliable right?... Well why not use the same principle with a pneumatic valve controlling the injection into the pipe, like a mini PV?.. use a 'normally open' version. As crank pressure rises with RPM the valve closes and shuts off the water. Simple and reliable? Think these are called 'Valve Integrated Pneumatic actuators' or similar...

Couple of larger examples..

True, but it's my understanding that most have hit the jacket.
If you take a close look at your manifold it's pretty obvious where the water jacket runs. I ended up having to drill two holes because the first hole I drilled put the end of the spray bar too close to the hull and I couldn't get the hose on it. I never hit the water jacket with either hole because it's easy to see where the water jacket is.

Think this can work. Must be balanced with some different springs to dial it with crankhouse or exaust pressure.

Un fricken believable. 6 pages and the thread is still on topic. I guess weirder things have happened.

appears dependent on the author..as long as the data is out there,who cares right?

superjetjim,I think the simplicity of a valve closed by water pressure right in front of the injector if the valve was contructed properly would be the most desirable,but the crank case pressure valve would deff work if it was setup just right as well. wonder what the reliabily of such a valve would be compared to the older style elec controlled solenoids used in salr water would be?

We won't be there. But there will be 2 havocs heading to get looked over then off to sponsored riders for the winter season until their hulls are done.
I really enjoyed the quick ride on the Orange Havoc. If I didn't already have my backie chan, I'd have a Havoc on order.
 
Has anyone ever measured the pressure in the cooling system through the RPM range? (pressures in the 4500 to 5500 RPM range being of most interest).

Master you referring to my water injection?
I ve been running it on my spec blaster for the whole 2014 tour with no issues.
Erik had one he made that we tried back a few years ago. I took a fuel filter and modified the internals for my boat. tested to find the right rpm shut off.
It's been working!

just looked at the first power factor pipe i got about 5 or more years ago. already drilled ,tapped , plugged
