You got the blocks mixed up. The Jet Block #2 has no flow and is way to restrictive and has 10 jets. Jet block #1 has 9 large jets and has pretty good flow. I need to seal it back up and throw it back on the new test system. Will do tonight.

Cathar's design compensates for the pressure drop by having a whole bunch of tubes, so it works well with any pump . As the flow rate increases, the pressure drop increases exponentially, so big pump owners need to have a nice pump, with a lot more head than flow, to run nicely.

I understand that. Unfortunatly I am trying to make use of the equipment I have at work and tiny jets are not an option. I was trying to make up for it by making large jets and bigger holes which I am not sure of it worked or not as I have yet to test it.

I really wouldn't give up on the jet block just yet. LeeJSmith's work is top notch, and uses a brass tube, for the jets, which I think is great because at higher flow speeds, a smooth inner surface in the tube is going to be less restrictive, and should result in a very focused jet.

Yeah, his work is looking damn good. Will see how the 9 jet block works out. If it isn't to good I am going to drop it for now and get back to my Lemon Block as it is doing real well. It is one of the few blocks I made that had any real thought and real time put into it. All the Rev. blocks and these 2 jet blocks were thought up and developed in less than 30minutes at work as that is about all the time I can squeeze in every now and then.

"Cascade" isn't hard to make, but it's hard to make it right. I think it would be a perfect exercise for you, JD.

I could make it. I am just trying to do it a little differently. I always new these jet blocks wouldn't be Cascade performance though. Not what I was shooting for.
