Sorry Todd -- This one was free and working The white turbo car in raleigh had it sitting around not installed. I called up Alex and told him dibs -- It's mine now!!

Anyway - I dont see any company names on it or logos.
It's round and about the size of my palm. There's a gas line on the bottom and one on the side. There's also a vacuum line on the top w/ an adjustable screw.
My question is >> Which gas line goes where? And how tight/not tight should the screw be? I'm very new to these things.

Probably best to take some pics to be safe. It doesn't sound like the one I have (Cartech). Can you get a picture?

Sure -- Here you go!

Whoa. Afraid I can't help you there, I haven't seen one like that before.

Ok got it! I looked around and found out that it's a Powerdyne RRFPR. You the ratios range from 6:1 - 8:1 - 10:1 - 12:1. I have no idea which one this is. But as old as it looks -- It's still something powerdyne sells, so it could be relatively new! :~

That's kind of like Vortech's too- you insert discs into them according to the ratios you want. Never used one personally though.

I don't know if I can help or not. Use as needed. My RRAFPR comes from BavAuto. It's roughly the same shape as yours. I just took a look at mine to see the orientation and which gas lines go where. Here's now the BavAuto RRAFPR works.

-Picture the round disk-like part as a wheel. The gas line that runs in the same direction as the axis on the wheel is the return line back to the fuel pump. In your picture this is the lower gas line connector. The other line is where it connects to the fuel rail (sticking out the side in your picture). In my case the FPR goes right in like the stock FPR.

-I don't know how the adjusting screw works on yours. On mine there is the vacuum line and then a screw to turn to adjust the fuel pressure. The adjusting screw has a lock nut that must be loosened first. There's also a cap over the screw that fits down on the locknut to keep everything clean. The key is that it's possible to screw the screw too far in either direction. I found it takes very little screw turning to get a pretty significant change in fuel pressure. I would avoid messing with the screw until you can install the FPR. Then base your adjustments on an actual fuel pressure gauge reading.

Hope this helps. I'm envious of you turbo guys. Hopefully in a few years I can follow in your footsteps.

Thanks Rich!
I was looking at it and yeah -- Looks like the side is the IN and the bottom is the OUT back to the tank.
The adjustment feature is a bleed type valve. The more you open it, the more boost is leaked to atmosphere -- which means the RRFPR sees less boost. Fully closed means the most fuel.
