FREQUENTLY ASKED QUESTIONS
Q: How can this system help my cylinder head business? I do some porting, but mostly late model heads where all you can do is a limited valve job.

Q: I donít do much port mapping with probes, How can I understand the information from your program?

Q: I donít understand pressure differentials what does this mean?

Q: Why do you have a standard kit with a standard valve? What if I use some specific valve angles?

Q: When I receive the kit, how do I get the software program?

Q: I have a motorcycle head, and donít think your kit will work on my head. do you have any special kits for this?

 

Q: How can this system help my cylinder head business? I do some porting, but mostly late model heads where all you can do is a limited valve job.

    A: The P-D Valveô system can map and show the air entering the valve flow (valve job) area, and it can identify why certain valve changes work or why some do not. The more rules you may have in this area, the more small gains will show up as power on the track.

Q: I donít do much port mapping with probes, How can I understand the information from your program?

    A: As stated by most who has used the P-D Valve system ďIts genius is in its simplicity.Ē the information produced in this program is nothing more than a view of your valve flow area not seen before. A pie chart and slices of the flow area are easy to see in color, the big advantage here is when you make changes and see not only, that the changes work (more air) or not, also the identification of the problem areas ďThe more you test the more you learnĒ

Q: I donít understand pressure differentials what does this mean?

    A: First off we are talking about compressible air flow, which means we have a completely surrounded conduit, (or port), which is susceptible to different areas (size) and velocities (speed) of air moving along its passage (port), as this air moves in this port the pressure will change as the area of flow grows in size and the speed of air slows, or the area decreases in size and the flow increases in velocity. The difference in pressure can be calculated to the area and velocity of flow.

    Flowbench and mapping these differences can show you not only how much Air is moving in the port (CFM) But where the air is in the port, also identify, good and bad (laminar or turbulent) flow.

    This test valve shows the Valve flow area not typically mapped before without obvious obstructions, (Pitot tube placed in the main stream of flow can obstruct the flow).

Q: Why do you have a standard kit with a standard valve? What if I use some specific valve angles?

    A: A good question with a two part answer:

    1. Many race classes mandate stock valve geometry, even if they allow after market valves. We have tried to keep the cost of this kit down, we use in most cases a stock style valve geometry, so the user can jump right in and get valid information.

    2. If you are using a specific valve geometry you can order your kit this way (with some small delivery delay, because our machinists build them one at a time) and receive the exact valve you use, or you can order as many different valve styles you wish after your purchase of the kit.

Q: When I receive the kit, how do I get the software program?

    A: The latest version of the program is available here. The software must be unlocked when first installed on each computer. This process can be completed instantly using the instructions on the downloads page.

Q: I have a motorcycle head, and donít think your kit will work on my head. Do you have any special kits for this?

    A: In some cases you may have to call our tech line and talk to one of our techs. You may also have to send us your head for a custom application, there are so many different head styles we canít possibly have all of them in stock. We do have a specialized machine shop for this reason.
