Well its all done.. wasnt too hard.. It was however hard to get a good picture because of how shiny the polished aluminum is..LOL

I was amazed after riding in it that the bypass valve does make a large WHOOOSH sound like a BOV does with a turbo.. but it only does it under heavy throttle/Load when the engine is building serious boost..

I must comment that the car does now seem to build boost much slower and it also appears that i have lost 2psi of boost.. I was getting a good 8-9psi before but im not only getting 6psi..

I know my exhaust is seriously hold back the HP, so its hard to tell if it has any more power than before..

Im guessing im loosing at least 100-120hp threw exhaust .. (at the track i take the cover off of the exhuast dump)

I do know one thing... if you feel the pipe coming off of the supercharger it is very hot after a 10 min. ride... and on the other side of the intercooler the pipe is cool to warm at most..

Valve should only make sound when there is vac present-like when you let off throttle or light cruise. If you are losing 2psi through the intercooler it may be a little inefficient, especially at only 9psi.
My blowoff/bypass valve sound like an airplane at light load or at the end of a run.

Everything is tight.. I had one of the hoses blow off on my first run... i went back and retightened everything..

It only Swooshes when i let off the throttle when giving it alot of big flipper..

The intercooler is supposidly good to 1000hp.. it is 4"thick by 28"wide by 12" high..

That looks like a nice setup. Who cares about the boost number as long as your making power. Now you should be able to crank up the boost for some more fun.
I have the 3.4" pulley on my D1SC and make about 18-19 psi. boost through an air to water intercooler.

I have the red Procharger bypass and like Steve said above it is a constant whoosh sound when in vac, at light throttle or cruise, but in my car it seems to make boost much faster than before the bypass was there.....

Steve I also have a D1-SC in my 92. Is the 3.4 the smallest pulley for the D1-SC? How fast does you unit spin with that pulley? I'm runnig Prochargers 1300HP A2A IC with 3.5" inlet/outlets.

The 3.4 is the smallest pulley Procharger sells for my 12-rib setup. I limit my revs to 6500 rpm, I can't remember the exact impeller rpm, but I know it is below the max. I think around 60,000 rpm. I see about 236 kpa (19 psi) of boost.
