2000 Chevrolet Camaro Z28

ProCharger:
P-1SC-1

Intercooler:
twin highflows

Naturally Aspirated RWHP:
305 RWHP, 325 RWTQ

ProCharged RWHP:
458 RWHP, 415 RWTQ

Boost Level:
8 psi

Exhaust:
stock exhaust

Vehicle Specs:
92 octane, stock LS1 engine,



Would a D-1sc on the same car net better hp/tq numbers, or would it be pretty much the same?

Curious because i'm looking at the d-1sc kit from epp. It would be on my stock setup until I get some more $ to do exhaust/ internal mods.

well from what i understand(im kinda still a newbe) is that 8 psi is the most you would want to run on a stock motor so 8psi from a p1sc and 8psi from an d1sc would make the same power. but you can "grow" with the d1sc and you will max out with the p1sc and want more later. so i would go with the d1sc. the only reason i hav a "p" is cause it was on the car when i got it

150 rwhp gain!!! (Why do people doubt a D1SC @ 10psi would make 650rwhp on a 383LT1???)

email Bob at EPP, hes the one to talk to about prochargers from my understanding

Thanks, I appreciate it!

The P-1SC and the D-1SC would both virtually produce the same amount of horsepower at 8 psi. The P-1SC comes standard with 3.5" thick intercoolers, where the D-1SC comes with thicker 4.5" thick intercoolers. At 8 psi, the thicker intercoolers would keep the inlet air temperatures down slightly from the smaller 3.5" intercoolers, which may allow the D-1SC to produce a slightly higher amount of horsepower.

From an article that was in a GM Hi Tech magazine. Bob

"Ryan compiled the raw data into these convenient graphs and as you can see there was approximately .5 psi less of boost drop off from the larger intercoolers. In addition the larger intercoolers were 10 percent more effective in cooling the intake air temperature, especially in the upper rpm range.... "

"...At 6500 rpm intake air temperatures were only 62 degrees with the 4.5-inch intercoolers, meanwhile, with the smaller units, intake air was at 71 degrees. As you can see from the graph, as rpm and boost increased so did the disparity between the two intercoolers, proving the potential with higher boost levels."

I didn't realize the intercoolers where different thicknesses between the two kits.
Another reason for the D-1SC kit.

Thanks Bob!

You can upgrade to the thicker intercoolers with a P-1SC kit tho.

However, if you are buying it new, you BETTER get the D-1SC from the start! Its only like $200 last time I checked. But if you get the P-1SC now and then change your mind later, it will cost you $1200+ to send in your P to convert it to a D. Plus you got downtime too.

I wish I had a D-1SC. I am spinning the P-1SC almost to the max impeller speed right now. Although it is making good power, if I were spinning a D-1SC at the same speed, it would make more power than my P-1SC.

Do yourself a favor and get the D-1SC from the start!

BTW- my bone stock engine with stock exhaust manifolds made 454 RWHP at 6psi. With headers, it went to 489 rwhp.

You can see my new setup in my sig making 632rwhp And I still have the 3.5" twin intercoolers...
