    A Valiant BJ / Powerdyne BD-11

    I learn something new everyday. I'm going to go pre & post supercharger. Now how do I figure out each nozzel size and water/Rum O:) ratio. I just want to use the one pump to feed the two nozzels.

    THANK YOU! I never though of that. Other than hooking up the brown wire to be hot when the boost switch is activated a 3 psi. Do I need to flip and swiched or adjustments in the Stage III programing. BTW. The wiring doagram in the PJIII instructions says the brown wire is for future...

    Thanks Bill. Nice set up. I have to lean the "after" the blower school of thought as well. Water is as hard as a rock at the compressor speeds. One less thing to come loose and eat the compressor. What do you use to trigger the pump?

    OK I'll hook it up. I could use your advice. If you look close that is not a carb. It is a Projection III EFI... I have the W/A pump & nozzel but, have no clue as how to rig it up. Should the spray nozzel be on the intake side of the BD11 (compressor side) or output side? I've seen what...

    Your right on that front. I have a water/alco. injection kit to install later. I want to try it this way first and see what it does. The EFI computer will record each run and show me any A/F, temp. spikes and EGT. I can fine tune after that or modify.

    STOP! DO NOT RUN YOUR BD11 WITH 928 MOTORSPORTS parts! You will distroy your engine & blower. Please do not use anything from 928. I will be happy to tell you why with photos, documents & the works. I have the evidance. Do you recall if the 928 bearing were stamped KBC. OMG! Buddy Karl is...

    I added a fine brass screen between the compressor discharge & intake. Just incase of FOD (forgien object damage). If the compressor internaly digest something or the compressor blade glue fails. This migh stope FOD from going into the engine.

    PCV Valves and other leaky stuff

    I'm putting a Powerdyne BD-11 on my stroker 408. Just because I have it. I got to thinking about boost preassure mode. An average psi for a BD-11 is 6 to 9 psi, not much. When the BD-11 starts making positive preasure (boost) what stops the presurized charge from leaking out at other sources...

    Now I'm getting to the fun stuff. I've had enough scrapping and painting for now.....I started to install the BD-11 and had to do a bit of body work for clearance. So far so good. I'm trying to figue out how to feed filtered air to the blower. The K&N is their to keep the bugs out for now but, I...
