Don't know what the F1 procharger kit is. Here is what ATI lists;

1998-02 LS1 F-Body
Description	HP Gain	Intercooler
'99-02 - 4 psi w/ P-1SC-1	35-40%	Twin Highflow
'98-02 - 5, 7 psi w/ P-1SC-1	40-55%	Twin Highflow
'98-02 - 8+ psi w/ D-1SC	60%+	Twin Highflow

I wouldn't recommend anything but the 5-7 PSI kit for the stock LS1. Make sure you get the one with fuel injectors, fuel pump, and programmer included.

[Tonys02Z28]

why not the 8 psi..

You dont want to push to much boost with a stock block. A F1 will blow up your stock motor without even trying Thats a HUGE superchrager, I was thinking of upgrading to one before I decided to sell my car. A D1 would be good for you and just pulley it so yournot running huge boost untill you build a forged motor. If you went P1 you would have to buy a new head unit later if/when you go forged and thats a waste of money.

OK, I found the F1 he was talking about (MONSTER 1000 HP), its not available on the LS1. The D1-SC is capable of more boost than the P1-SC if you were looking to upgrade later. Problem there is even using the D1-SC with a low boost pulley you need a custom tune and the Fuel Injectors that come with it are too big for the lower boost. The stock LS1 bottom end will limit you to 11 PSI anyway even if you ran 130 octane race fuel. 7 PSI is approximately +50% HP, almost 500 HP on the LS1. Unless you are planning on MAJOR surgery (basically upgrading the entire drivetrain) 500 HP is more than you are ever going to use.

well like i said earlier when i was gonna get new cam new heads,new fuel injectors,new pistons,new tranny,full ssuspension,new rear end and new fuel pump and i have a performance shop thats gonna do all that and tune it for me.so with all those upgrades which one will work the best..remember im gonna up my nos shot from a 125 to a 175 or 200..

you plan on spraying that much and wanting to add a blower or turbo?

After doing all this research I think I want that downpipe kit I linked (kidding no emissions on a 1998 - 2002 isn't smart)

If you are really planning on building your Z28 in stages the D1-SC is for you. Stage I you can go up to 11 PSI with the stock pistons, rods, and crank. Stage II with all Forged parts you can up your boost as much as you want to the head units max (D1R is 30 PSI). Stage III would include porting and polishing your heads and intake etc. Seriously FORGET nitrous! N2O is a great cheap way to make power but if youre already doing the Supercharger route just stay with the S/C.

ATI Procharger - Camaro-Firebird

Check out where I've been getting my info from. They will let you customize your order to just what you need. You can get the D1-SC or D1R with the rest of the parts from the P1-SC for now (pulley it to 7 PSI). Then you can upgrade Fuel Injectors later when you go Forged. You're talking about SERIOUS Firepower here. The P1-SC on 7 PSI making 500 HP is more than you are going to be able to use. You will end up afraid of your own car!(at least I would be!)

A small shot of nitrous if you really wanted it like a 50 shot would act as a charge cooler like the methanol but I dont think I would use a huge shot and FI. One or the other would be plenty for a street car. Honestly anything over 500 on the street is a pain in the butt to hook up. Fun yes, but again depends on what your going for. Just dont build it to the point that its no longer fun to drive.

[Tonys02Z28]

i love my nitrous and i dont want to give it up,this is like my drug i want to have the most power out of my car no matter what it is. im not gonna be driving it on the street as much as u guys think trust me on that.my car with the spray dynoed 450 to the wheels and goin 50 mph i still spin so trust me i know.i just want to have it all done in one shot instead of goin back and upping my stage u know.so if i just get the D-1SC custom kit then ill be good..my plan for building this car is to not bee 500 to the wheels i want to have alot more than that..i do have a second car so i wouldnt be driving it that much..

I've seen guys run monster turbos with bad turbo lag use that 50 shot of N2O just to beat the Turbo lag but honestly either build a N2O motor or a Supercharger motor. You are paying for both the way your doing it.

Well if you already paid for a NOS kit I see the dilemma. With the D1-SC you are going to need different pulleys ($100 each), different Fuel Injectors ($300 a set), and a custom tune to the PCM each time you upgrade. Don't get me wrong I love N2O but refilling SUX! Your best bet is a ton of nitrous with a Jacobs Mastermind Controller (or equivalent), a remote bottle valve opener and 3 15lb bottles of the funny stuff.

ive had my nos kit for well over and year now and only refilled it twice..i dont spray that much ever cuz usually i dont need it..i was also planning on already gettin the bigger injectors before i have the guy put the procharger on and for the tuning i have a local lsx shop tune my car and he is excellent...

That was exactly the point I was making. Same for my last NOS car, opening the valve was a pain in the ass (street racing at least) and I hardly ever used it. I like the S/C and Turbos better because they are always there with power on tap. Anything you do is going to require injectors and a tune. The P1-SC is a package deal where its all included. N2O is by far the EASIEST, CLEANEST way to make more power. You can add a second stage to your kit and then the controller adjusts the HP gain from idle to redline. Two 200 HP NOS kits should get you where you want to go for a fraction of what the S/C costs. With Forged Internals and the right CR you can get 1,000 HP with the controller for what the S/C costs for 7 PSI. Its all about your choice.

yeah ive looked into that but decided to go supercharged but yeah i here u on opening the valve part..but isnt the D1-SC better than the P1-SC,POWER WISE..ill have all the supporting mods so i want to have one of the best stages that way ill stick with it..

Of course the D1-SC make more power. They don't list the max, just 7+ PSI. The D1R goes up to 30 PSI I believe. Just run your 200 HP N2O for now and install whichever S/C you choose when you rebuild your engine. That D1R is going to require ALL Forged parts and a 9.0:1 CR.

P.S. If I ever go N2O again I will spring $200 for the remote bottle valve opener. I never want to get beat by a ricer because I had to open my trunk and open the stupid valve then purge etc.

just buy macleods car, prolly cheaper in the longrun and its already making over 600whp,haha!
