Pulley What size? I have Procharger D1 on the way. Trying to figure out what pulley to start with. I currently have a 3.4, 3.2 and 3.0
Is the 3.4 too small to start with??
I am shooting for 600 or more rwhp.

With the SDCE crank pulley which is 7.25" a 3.4" will max out the D-1SC at 7100 RPM or so. If you want to max it out sooner you can do that by running the ATI 8 rib crank pulley which is 7.65". This will allow you to max the D-1SC out at 6800RPM or so with a 3.4 pulley.
By the way i have an 8 rib 7.65" that I'm going to sell soon. Tell me if you want it.

Ed, I don't remember if I asked you yesterday if you have upgraded your fuel system to handle the increase in power. We see 600 rwhp as the upper limit to where we feel safe with using the stock fuel lines. Past 600 rwhp, we've been swapping out the whole fuel system, as we did on these two cars.

I don't know how it'll translate over to your 383 but this is my set-up.
9.1 comp 346, Ported heads, TR 224/227, SDCE tensioner, 3.50" 8-rib pulley, dual 3" inlet hat, TTS Longtubes, 3"y - 4" over axle - 3" dual exhaust, M6, 12bolt w/3.73's.
18 deg timing, 13.5-14 psi @ 6200, 93 octane
672 rwhp/600 rwtq SAE

The 3.7 with the SDCE is the best overall performer for me, the 3.4 picks me up ~2psi of boost but the car doesnt pick a ton at the track. I would just put a 3.7 on it and call it a day, its where the bllower really likes to be if you shift around 6800.

And if the 3.4 will bring in the boost sooner.
Plus I would have to order a 3.7

Uh oh, Ed got his D1 and is pullying up ! 
Hmm, wonder if I should learn from your mishaps and sell my NX MAF setup and put the proceeds towards a D1 too (keeping the P1 for smog like you're doing).

But it was my fault for the boom. Not the Nitrous.
