Super Charger Lesson I'm new to SC. I've read the sticky on turbos (very good btw) but I have not been able to find the same information on super chargers. I recently purchased a used ATI Procharger d1sc for my 2002 LS1 engine (going into a 1st gen Camaro); I was wondering what besides the SC head unit, intercooler, tubes, and FMU what will I need? I plan on using an 8 rib belt setup but what else do I need? Do you have to replace or upgrade anything else on these engines? MAP, for example? Thanks!
Did you buy the whole kit, or just parts?
You will need tuning, gauges(boost and fuel pressure), fuel pump, and fuel injectors(42# or larger). You can see the mods I have in my sig and on my site, and the pathetic power I'm making, and problems with the car...

Super Charger Lesson I bought a SC pulled from another car. Are 60lb injectors the correct size for my application? Should I be thinking about a cam swap before I install the engine? I was planning to use a Walbro (GSS340) electric in-tank pump that delivers 40 gph @ 45 psi (based on 13.5 volts) will this get the job done?
Well 40gph = about 170lph. Most people on here use 255lph pumps.
Injector sizing all depends on how much power you want to make. 42# injectors will hold up to about 550rwhp forced induction. I am planning on getting a big motor (408ci) so I got larger injectors to accomodate for this.
You do not need a cam swap, however a cam will get you a little more power from the motor. You can still make engine destroying power with a stock cam. FI cams are usually "split" pattern cams, with more duration and lift on the exhaust, such as a 224/228. My cam isn't the greatest for FI, but I feel its better than stock.
So you didnt answer my first question, did you buy just the head unit, or a entire kit?

You will need to call ATI then and order the rest of the parts that you will need. Read these directions and you should be able to figure out what you are missing. Also, I'd reccomend starting off with an SDCE 8-Rib pulley kit instead of the standard 6-rib. It will eliminate the belt slip that I and many others have expirienced with the 6-rib set-up.

Stay away from the FMU it is not needed, stick with the tunner setup, Injectors and pump and a good PCM tune will do. 8 rib upgrade a MUST!!
Even better than ATI, give Bob at EPP 260-483-9300 a call he can beat ATI,s prices and set you in the right direction with everything you need. Even fill you in on which cam as well.

7.25 Crank Pully
3.3 RR Supercharger Pulley
D1 Supercharger
~6000 RPM peak power
Blower Speed is ~55000 rpm.
I run a very large custom front mount and intercooler setup (only about 18" of piping total). If you are running the ATI kit, you may not be able to get to 16 psi even on the D1 due to the twin intercooler restriction. With the P1, maxed (spun to 65k, 3k over max) you'll probably only get a smidge above 14 psi.
All of the cars that we have maxed the P1 out on (only done with the SDCE) with the stock ATI piping and intercooler, they peak boost was between 13-14 psi. The cars all put down between 610-650 RWHP.
