P1sc Procharger upgrade Hi guys, this is my first post so bear with me.
I'm looking to upgrade my p1sc Procharger unit to the d1sc on my 98 Firebird (ls1) Procharger will do the conversion for around $1,100. Does anybody know what would all be involved? As in, will I need to upgrade pulleys, or is it a standard swap. I'm afraid of starting a 'one things leads to another' money pit.
My primary reason for upgrading is simply the noise. I have an older version, and it just howls like crazy at low rpms, and I honestly can't stand it. I've heard the d1 units run much quieter. Any thoughts?

Thank you for the reply.
I just got off the phone with Procharger, and they said the D1sc swap will not replace the straight cut gears with the newer Helical cut ones. This is what I was after to reduce the idle noise.
I'm now thinking about upgrading the 6-rib to an 8 rib. That will change the crank pulley from 5" to 7.65". Maybe that will be enough to get it out of the low idle chatter area.
Any thoughts on this would be very much appreciated.

You might be better off money wise, selling your head unit and buying a new one, then you can get one with the helical gears. Give me a call for a super deal on one.
The D-1SC will require switching to a larger pulley on the head unit to keep boost at the same psi that you're currently seeing. http://shop.brutespeed.com/ATI-DPxxx...-ATI-DPxxx.htm (Pulleys) A six rib D-1SC (6" crank pulley) on a basically stock F Body with headers, no cats and exhaust will use a 4.0" blower pulley to make 7 psi of boost. Swapping to the 8 rib upgrade isn't really necessary unless you're going to run more than 8 psi of boost. Here is my link to the 8 rib upgrade. http://shop.brutespeed.com/ATI-1GJ11...-1GJ115-08.htm

Hi guys, thanks for the replies. Alchemist, your D1 does seem a little loud, is that with straight cut gears?
I finally got my car back today after getting the 8-rib kit and new pulleys on. It went from 4 lbs. to 8 lbs. of boost.
It did decent power on the dyno (412RWHP and 410 torque), but choked out at 5500 RPM. I presume it needs a bigger fuel pump and (hopefully not) injectors. Any suggestions would be appreciated.
But back to the point of this thread, the blower is still too noisy for me at idle, and I am just going to have to buy a new head unit. I just really hate to spend $2000+ to get rid of a sound, so i'm debating on doing a D1 with helical gears. My new pulley setup is 3.55" blower / 7.65" crank. Will I be ok to just stick a D1 in there and tune it again? Or will it make too much boost?

I agree, somethings not right. Bob

It should not quit making power at 5500 rpm, a ProCharger will normally keep building boost the higher you spin it to. Do you have black dust all over the blower? Bob

That makes sense, yes it sounds like it is on track to make a lot of power. The blower will make a lot of power from 5500 to 6500. Do you have a forged engine? Bob

Yeah, something isn't quite right. Granted, if he's completely stock, the motor makes about 330/330 at the wheels. With 8psi of boost, he should pick up a solid 150rwhp, which would put him around 480 at the wheels, give or take. So with it stopping at 5500, maybe the dyno operator saw it go lean and lifted out of it, which is smart.

Conan, as far as I know, the car is pretty much stock. I bought it from a guy who passed away right after installing the Procharger, so unfortunately I don't have all the details. But it seems the internals are all stock. Exhaust is still stock manifolds and awful pipe (next on my list) with cats removed and Flowmaster muffler. There was work done to the fuel system, it had a booster installed that we ended up bypassing. I wish I knew more about it, but I guess I gotta start somewhere.
No, its not forged, which is why I'm hesitant to add much more to it.

Side note for you... Like ALCHEMIST said, my D1 is noisy as hell at idle too. There is no mistake something is going on under the hood. I had a guy tell me at the gas station last week I need to have my serpentine belt looked at LMAO

Ok that's making a little more sense, with a stock engine and a restrictive exhaust. The flow master catback is one of the worst, and manifolds don't help either. Get the fuel system up for the job and see what she does all the way to 6,500. Then start to add some better parts to the system.

As for the replacing the head unit, the noise mine makes is louder than the standard procharger idle whine. I'm willing to spend the money to replace it with a quieter version, and sell mine to someone who doesn't mind the sound. Unless anyone has any suggestions on how to quite this thing down, it looks like my only option.
