PR Turbo Setup - Update on page 13

I picked up my turbo kit from PR Friday last week and spent some time on Saturday and Sunday installing it. If it would not be my highly custom bike the install could be done in as little as 3h.
Parts fit very well, the header pipes go on very easy, much simpler than the Stage IV pipe headers. I went with chrome headers, chromed intake side of turbo and jet coated hot side. The kit comes with a chrome heat shield but I think I will make a custom one to match the flow of my bike.
Made my own SS braided oil lines. The kit comes with pre-made oil lines that install very easily but I wanted mine to match and tie into my existing setup.
The new fuel pressure regulator comes with a bracket and hose extensions to fit under the stock left cover. Again my custom setup required me to make a custom bracket behind the plenum (pressurized air box). Fits in perfectly.
Instead of the kit supplied mechanical pressure gauge I got an electronic version from Auto meter to math my gauge setup.
The last peice missing at the moment is a custom down pipe as I will be using the Stage IV 2 into 1 muffler. I just like the looks of it.
For now I installed a simple diverted to the exhaust port of the bike.

Download the custom PCIII map, set the fuel pressure regulator to 65 psi at idle and hit the start button. Engine fired up right away.

I have not had a chance to ride it, might take a couple more weeks as I will spend the rest of the year in Cupertino, CA looking for a new house in the San Jose area.

Pictures will follow once everything is done.

I will keep you posted!

Ok guy here we go:

This is the turbo itself without the heatshield and without the custom downpipe. Just added a diverter to be able to run it for now. The cool side plus the header pipes are chrome, the hot side is jet coated but will be hidden behind a chrome heatshield.

LCV and standard vacuum gauges stay. Bike starts and idles just like a stock bike.

This is the plenum that connects both throttle boddies and feeds the pressure from the turbo. It gets bolted down by a plate that spans the frame.

The setup comes with a special, adjustable, boost linked fuel pressure regulator. You adjust it to 65 psi for the stock setup at idle and load Nigels map to correct the fuel delivery.

Finally the turbo needs some oil to live. The package come with a very elegant solution that taps into the oil delivery of the cylinder heads by using a longer banjo bolt at the bottom of the stock oil lines. In my case I made some changes to my custom oil lines to tap into that line. Don't have a picture of the return line but it simply uses the drain bolt behind the rear cylinder on top of the engine case.

More pictures to follow once I get the customized exhaust (based on the Stage IV pipe done. Just have to brush up on my welding skills and get a couple SS bends to modify the current Stage IV header.

Hi Oliver,

That is looking real good. Will be interesting to see your final dyno results. Been considering the turbo myself. Should make a nice setup with the stage IV (and my NOS). At some point looks like a chain final drive will be needed, but that is an easy conversion.

Just a thought - do you have any short v-stacks inside that pressure box to smooth the air flow into the throttle bodies? I would think that even a small stack with a bell radius would be worth the effort.
