Need some advice with LS1 Supercharger I'm currently thinking of purchasing an ATI 5/7 pound super charger kit with intercooler for my 2000 SS Camaro and a little scared about making a bad purchasing decision. My car is a daily driver with 28K miles on it, exhaust, headers, throttle body as well as the intake manifold have been changed out, so from what I understand this is ideal for a super charger.
Sorry to be so winded, my question is this am I right in thinking that running at lower boast levels is better for my situation? What other components will I need to change out when I do a super charger at the 5-7 boost level with this kit? Will I have to change my clutch and drive shaft? What kind of Hp should I be expecting by just bolting it on and running it?
Thank you for your help, I really appreciate any input you might have. <img border="0" alt="[USA]" title="" src="graemlins/patriot.gif" />

Re: Need some advice with LS1 Supercharger You are going to have to get a inline or a intank fuel pump, injectors, dyno tune. I basically had the same mods as you and installed one in my car with 8PSI and added 133 extra horse to it. I also have the P1SC and that kit starts out at 5PSI. With super charging a car you are adding more HP to it, so the more power you add the more money you are going to have to spend. Example.
1. I dynoed 501 at the wheels and 476 torque.
Now i have to save money to get my internals and heads to reduce the compression. Blown cars like lower compression as to the n20 cars which is higher. The ls1's can't handle more than 550 on the stock internals with boost due to heat and excessive wear. I didn't change mine yet( I should have) but haven't. It would be smart to atleast put a safty loop on it so you don't pogo stick it. The clutch i would change if stock.
It all depends on your mods and how much boost you run with the type of head unit you go with. There is the P1SC,D1SC,F1, all of these run different boost levels so it's up to you on exactly what you want to run with boost.

Re: Need some advice with LS1 Supercharger This might be a stupid question but I can't help it. Yon mentioned a safety loop, is this a release pressure valve that you are talking about? The kit I'm thinking about getting is the P-1SC with 5psi of boost, which is the same one you have from what I understand just running lower boost. Does this kit include everything I need minus the injectors and programming? And you mentioned a concern about higher compression ratios and changing the heads out. Will I need to be also concerned about this running 5psi? I know stock compression is 10.1:1 which is very high as is, but I don't know what this turns out after running 5lbs boost nor is the engin can handle it?
Thanks for the help <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Re: Need some advice with LS1 Supercharger Welcome to LS1Tech.com and FI!!
Your best bet at this point is to just read, read, and read some more. Don't buy anything until you've researched it thoroughly. Try doing lots of searches and read as many posts as you can on the ATI ProCharger setup you want to run. There is a WEALTH of information on this board, you just have to dig a little.
Best wishes.
Randy.

Re: Need some advice with LS1 Supercharger I'm not super knowledgable about blowers, but could chime in based on my car.
I have the Vortech 9lb aftercooled kit on an otherwise stock motor. The kit has been on for 7,000 miles with absolutely no problems (except for lack of worthy opponents <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> )
The car has very few other mods, (none to the drivetrain) so I do NOT run it at the track. The first pass from a dig could waste the clutch or break something in the rear. I only "enjoy" the blower from a 30 MPH punch and have only street raced it from same. It is stupid fast by my standards and a very enjoyable car. The Vortech kit is complete with all the fuel system upgrades (T-rex pump, upgraded injectors) and they ship you the programmer for the computer. etc. I just had to get colder plugs.
The car is not a daily driver, but could be.
As for the other suggestions I see here, it depends just how fast you want to go. Mine is making plenty of power (probably 430 RWHP (505 flywheel), based on another stock car with same kit).
Any advice I could give you would depend heavily on how the car is going to be used. You can certainly drive a 5-7 psi car daily. If you want to race it, you'd better save up for a clutch and a rear end. Get a kit that is complete and get a professional install from a reputable shop.

Re: Need some advice with LS1 Supercharger Do your homework in forums like this, and make the best choice for your needs. Upgraded fuel system and REAL dyno tuning should be considered bare minimum. I'm making 460+ RWHP on 8 pounds of boost, stock engine, stock exhaust manifolds and cats, on 91 octane fuel.

Re: Need some advice with LS1 Supercharger I had the tuning done at a place called Force Fed Performance, about 2 hours from my place and several days from yours! My car is the SOM one at their website >>
http://www.forcefedperformance.com
We were pleased with the numbers since I'm running factory everything (except injectors and cat-back). I was tempted to try the nitrous as well, but we kept our attention on the supercharger tune. We also did it on 91 octane pump gas since I didn't want to mess with mixing fuel.
We couldn't run more than 17 degrees timing at WOT, or the knock retard would kick in. But I'd rather know I'm clean than try to eak out a few more HP. I can't hook this up now, so why bother?!

Re: Need some advice with LS1 Supercharger Thank you everybody for your help, I have learned a lot of info over the past few days. Now it's just a question of(5psi or 7psi) and where I will get my tunning done. I sure wish I knew how to use Ls1 edit, I can't stand not being able to do everything when it comes to working on my car. I'm digin all the mods and superchargers on your cars, I will be there soon <img border="0" alt="[driving]" title="" src="graemlins/gr_driving3.gif" />
Re: Need some advice with LS1 Supercharger Any question you have isn't stupid due to you want to learn! I was talking about a drive shaft safety loop, it's a piece of steel that the drive shaft goes through(kinda like a band aid on you're finger) to keep it from dis connecting and digging itself into the ground and launching you're car into the air. Yes the kit includes everything you need for the install of the charger including the 2 intercoolers. No you won't have to be too concerned about 5-7 LBS of boost without heads. you dont have to have heads on the car right now(I dont with mine yet)in the long run you should get some heads so you can flow more air through the stock ports and lower you're compression.
Look at it this way, you are forcing air through a straw so it's restricted as if you are forcing air through a hose which is bigger in diameter which means less work for the air to get fed through it.Getting heads would benefit in easier access for air to flow and lower compression. This isn't a have to do thing right away with 5-7 LBS of boost.
With what i see you have done to you're car now, you will have no problem running even 8PSI. You're motor can handle it with the charger and mods but the next thing if you get the charger should be heads and internals so you have something to back up all that power. you're compression will change very little with the blower( go up) but not enough to worry about.
The main thing to worry about will be opening all that restriction up with heads, since you already have the intake ETC. When I get heads and internals for my car I will be around 9.1:1. I would'nt worry about the heads and compression yet too much unless you have the money to spend.

Re: Need some advice with LS1 Supercharger Oh one more thing I forgot to ask about is the fuel injectors, I see that the performance injectors are rated by presure ratings. How do I determine which is the correct one for my application, is it based on the fuel pumps presure? Anybody know off hand what presure pump comes with the ATI kit? Thanks again <img border="0" alt="[USA]" title="" src="graemlins/patriot.gif" />

Re: Need some advice with LS1 Supercharger Okay I have even a better question now, what's this about California state Carb number not stamped on the ATI ProCharger? Will the car pass smog other than this? Am I just up the creek if I want the ATI kit? Please help!

Re: Need some advice with LS1 Supercharger Sport, the P-1SC model does have a carb number. It isn't stamped on the housing, nor does it have to be. The housing has a serial number on it. When you take your car for smog, the shop will look at the documentation that ATI provides you. They'll then call ATI and reference the serial number on the unit. ATI will tell them, "Yep, that units CARB number is blah blah, and it is 50-state legal." That will get you through visual, and it will just be the sniff you have to pass.
Now for folks like me that went with the D-1SC, we might have some problems with visual. The serial number on that unit will not get a response out of ATI that "Yep, it's legal". We'll have to find a shop that will look at the documentation, see that it references a carb number, and then not notice that it is stamped "D" instead of "P". Basically, find someone that won't call ATI!
