D1SC Procharger Setup- LS1 Camaro
D1SC Procharger Setup- LS1 Camaro I have a 2002 LS1 Camaro with roughly 110,000 miles on it. It has bolt ons, headers, 255 walboro pump, yank SS3600 stall, ford 8.8 rear with 3.73’s and suspension (koni/strano) and brakes (cadillac ats) done.
I am new to forced induction, but have been reading on it the last while.
I just bought a D1SC used procharger (6 rib setup). I pick it up this weekend and plan to install it on my car in the fall / winter. The previous owner tells me the crank pulley is just under 6” (I am assuming it must be 5.85” from my research) and the blower pulley is 3.45”
It is a twin 4.5” intercooler setup. I have a few questions:

It is a twin 4.5” intercooler setup. I have a few questions:
- I think this setup will put down between 500-550rwhp- what size injectors am I best to go with? My thought is 60lbs to give me room to grow some, but maybe this might be overkill and cause me issues with the current setup?
- I am thinking the walboro 255 might be borderline adequate, I was going to reach back to where I bought the pump to see if I can drop a bigger one in since I used the hotwire install kit. My thought is I likely don’t need to run new wires again. What size pump should I be targeting?
- I was told this setup with the pulley size should be about 7psi - how can I verify this? Can I safely put down a bit more power? Also, I am a touch worried about the 6 rib setup, but not sure it’s worth it to push to a 8rib setup yet.
- I was told he didnt pin the crank, what are my options to do so? Or should I bother?
- I am doing some reading on adding a meth kit, but is there anything else I should be considering at this point?
- Do I need to go to colder spark plugs? If so what range and what gap?
My $.02.

My thought is 60lbs to give me room to grow some, but maybe this might be overkill and cause me issues with the current setup? I'd get some genuine Deka 80lb. injectors to start, I made 600whp on them with pump gas.

My thought is I likely don’t need to run new wires again. What size pump should I be targeting? I'd add an additional 255 to the bucket with a hotwire kit from Racetronix on a hobbs switch, easy and cheap and good to well over 600whp plus it will work well with the stock returnless fuel system.

Also, I am a touch worried about the 6 rib setup, but not sure it’s worth it to push to a 8rib setup yet. Get the current setup up and running and working before worrying about upgrading. Boost is a measure of restriction so it will vary a little.
- I was told he didnt pin the crank, what are my options to do so? Or should I bother? Yes, pin the crank, lots of kits out there that make it very easy.
- I am doing some reading on adding a meth kit, but is there anything else I should be considering at this point? Meth isn't necessary until you start getting up over 12-14lbs. Start looking at everything south of the engine, clutch/trans, diff. as they'll all be tasked with handling the additional power. The 4L60E trans is pretty weak as is the stock rear end, plan accordingly.
- Do I need to go to colder spark plugs? If so what range and what gap? TR6 plugs would be a good choice, probably gap them in the .028-.032" range to start.

1. I agree with the 80lbs injectors. What I am not getting confused on is if I need to upgrade the fuel rails and the different connectors I might need. I have a stock ls6 intake manifold.
2. Do you have any info on how to setup that fuel system and exactly what is needed. I reached out to racetronix but they just kind of linked me to a diy kit and upgraded lines/rails (which I hadn’t even considered). I have no plans to run e85 as it is not available here in Canada.
3. I still intend to do meth so that it is tuned in on this tune and is there as more of a safety.
4. The procharger kit seems to have the old blow off. Does anyone know what the new proflow blow offs that come with the new kits changed? I think they are $200-$300. Is there any benefit to ordering a new one, or as mentioned earlier, just get it running? Here is a photo of the one I have:
