Procharger Stage 2 Install

[Process]

The 4.385 stage 2 on the d1 makes 15. 4.75 made 12.

5.00 pulley on stage 2 kit. Procharger said it's supposed to make 12lbs but heard it only makes around 10.

The math on the 5" says almost 12, but in practice I've seen about 10psi at stock redline, maybe a touch more

So with cat deletes 4.385 should do 14 I'm guessing

I think 14 would be a little too much for pump gas. I would like to run E85 but not sure the stock fuel pump would support that much and Lund won't tune E85 with stock pump.

Sam from coastal running 15 lb on 93 pump maybe with some torco

3.4 is the smallest Procharger makes for the D1SC?

Lol

Ya but that's usually used on a non stage 2

On the stage II it looks as though 4.0" is as far as you can go within impeller speed limit of 62K. 4.0 gets you 61.5K impeller speed. However there are guys who have over driven them to 110%.

I initially had the 4.5 pulley on to get me over the 700rwhp mark but the tuner was uncomfortable running 13psi on pump 93, so we're trying to tweak the tune a bit using the 4.75 pulley right around 12-ish psi.

 

[z06psi]

Yeah my goal is 650-700 rwhp on 92 and then with Meth to go on in a little while. So damn expensive over here. No e85 access and 100 is $10 a gallon at one location. Hawaii sucks for big power.


50/50 meth/water should make 5 gallons last a little while.

 

[Phils15GT]

Sounds like I need to order the 4.75 pulley for it. Wish I would have known the pulley setup they sent me wasn't going to make the 12 psi I asked for. Now I have to buy another pulley and belt.

 

[z06psi]

Who did you buy it from? Terry (Beefcake) and I discussed it first.

 

[Phils15GT]

I bought it from lethal. I told them what mods I had, elevation, and how many lbs of boost I wanted to make. They passed that info along to procharger and procharger specd the pulley specific to my build. It was supposed to be 12lbs.

Understood. Im keeping the ID1000s, I was told there would be a 30% restocking fee if I return them, even unopened and I pay for shipping. :tsk: Hopefully the Lund tune is decent enough to get me by or limp my car home from install. If its bad, Ill just get a local shop to do the real tuning on dyno.

Weirdest thing. This afternoon, since I was putting in my stainless clutch line, I went about hacking up my JLT oil catch can and with new hose and fittings plumbed a custom PCV route for my D1SC setup. Instead of using the two PCV inlets to the intake tube like the instructions (like I had) I ran the PCV from the passenger side behind the engine to the driver side PCV. Just before the driver side PCV, I put a 5/8" tee and dropped it down towards the strut tower, where I tied in the 3/8" vacuum line from the y splitter behind the engine. I then ran the single 5/8" PCV line from there to the oil catch can (with new 5/8" barbs on both sides) as a single inlet to the intake tube fitting before the blower inlet.

I just figured if it worked it would reduce the amount of oil making it to my intake tract and maybe reducing the potential for lowered octane effects.

What I found was that it smoothed out about 90% of the surging I was experiencing at the 0-5 inch of vaccum mark mid throttle. It's not totally gone, but it was SO MUCH better and smoother. I stopped and checked it and told myself it was all in my head. So I took it back out later with my wife and she said the same thing. I checked all the fittings, and again, everything was tight.

Not what I was shooting for, but hell I'll take it. That's a hell of a bonus for getting the oil catch can back in my loop. Now, rather than surge, surge surge surge surge at mid throttle, if it finds that spot, it's just for a second and it's gone.

Just thought I'd share that around in case anyone was thinking of doing anything similar. I just hated that ProCharger had me putting a rubber hose onto my PCV valves. It was killing me. So instead of cutting up the original parts, I bought hose, elbows, and tees and used Ford PCV clips. Worth every minute, and much cleaner too.

Maybe I'm doing my math wrong, then. Isn't the stage 2 kit an 8" dedicated 8-rib crank pulley for the blower?
Stage II System:

8-rib dedicated belt drive system
P-1SC-1 up to F-1R (600 HP to 1,225+ HP)
Additional 230+ HP to otherwise stock motors running 91 octane pump gas
100% reversible, no permanent modifications, no drilling or modifying
Patented 8" supercharger crank pulley that fastens to the factory balancer
Belts and pulleys can be changed without removing the supercharger
Upgradable to “Red” Race bypass valve
Handheld tuner available

And I asked about overdriving the blower when talking to Procharger sales and the guy I spoke to said the P1/D1 series impellers hit a wall at 100%, and no matter how much faster you spin them, they are going to flow that 100%. The designs on the impellers on the F1, etc., are different and can be and often are overdriven on purpose built race applications.

I'm not quoting that as gospel, because I would think the faster it spins, the more air it would compress, but that's what the company that makes it told me when I asked.
