I am no expert so here's the question: Do I need to or would it be best to change out the stock IM on my 2000 Camaro SS (LS1) when adding a ATI Procharger P 1SC-1? Only mods will be long tube headers, and possibly true dual exhaust. Only looking for slightly less than 500 whp so won't be extreme on the boost on the Procharger. Thanks!

umm , your not getting 500 hp with that, and yes the ls6 instake would be a nice upgrade , i did my ls6 intake with the p1 install . your gonna need a cam and the larger intercoolers and meth to get 500 .

Really? So, you don't think I could get 480 whp or so with up to 7 psi? Also, I was looking at the FAST LSXR intake that can accommodate 90, 92, or 102 throttle bodies as opposed to the LS6 intake. Comments on this setup?

I know a 2001 SS already has an LS6 manifold...so might be worth checking what you currently have.

The stock LS6 intake and TB will allow far more power than the P1 will ever make.

Although given the P1 will be the restriction I guess it is possible a better intake may help slightly.

you need a front mount or meth and the twin ics and a cam to get there . stay with the ls6 intake , spend the money on a meth system .

I'd shoot for 8 psi, with a good tune you shouldn't have any problems with it. Your 2000 Camaro has an LS1 intake, the LS6 intake is worth an extra 10-15 rwhp. I recommend going with the ProCharger 1GJ204-SCI kit, which is the D-1SC 8 rib with the larger 4.5" twin intercoolers. The 4.5" twin intercoolers generally do well up to 14 psi of boost. The P-1SC-1 comes with thinner 3.5" twin intercoolers, and comes standard with a six rib wide belt. The 6 rib also uses a small 6.0" crank pulley, where the 8 rib uses a larger 7.65" crank pulley. With the larger crank pulley you don't use a small of a blower pulley, so the system ends up with better belt wrap. Check out the system I have at the link here. http://shop.brutespeed.com/ATI-1GJ20...-Speed-Kit.htm

What is included:

ATI 1GJ204-SCI D-1SC Serpentine Race Kit with larger head unit options
Siemens 60lb Fuel Injectors with 80lb Siemens option
Walbro GSS340 Fuel Pump with 2nd pump option
ATI Performance Products 918853 Harmonic Balancer
ATI ProCharger Crank Pinning Kit

People have seen 500 rwhp with your combination and 8 psi of boost, it depends on what kind of dyno your are on, elevation, etc. Bob

Not a direct comparison, but FWIW, my stock LS6 with headers made a good 560rwhp with the p1sc on my old Z06 with the small twin I/C's and 60lb'ers.

^^ not on 7lbs I bet.

I realize they are different installations, but don't underestimate the P1SC-1. My 2004 GTO P1SC-1 installation on a completely stock engine and exhaust put down 450 to the wheels....a few years later and many mods(including forged short block etc.) I am at 650ish with a few more to go once I get a few bugs worked out.....

On 8 psi, p1sc-1, no meth, stock procharger intercooler, 42# injectors, and a tune we put down 435 to the wheels on a stock 5.3 silverado. I would have to say that your goal lies in your tuners hands.

Also that was a 4wd silverado also.

I honestly dunno. It was with whatever pulley came on the head unit new. Pretty sure it wasn't more than 8psi, especially with the headers, but it's been a while. Not even a BAP on it, but it did run a little leaner than it should've near redline.

Thanks for all the replies. My apologies for unintentionally creating a debate as to whether or not 500 hp could be achieved with this setup. That was not my intention. My objective is to add HP to my stock LS1 without having to modify the engine internals. I want to stay with the P 1SC-1, limit the boost to 7 psi, and add headers. It sounds like the FAST intake is not needed and the LS6 intake would provide enough increased air flow over the stock LS1. Are there alternatives to the LS6 intake given no EGR and having to modify the underside of the LS6 when replacing the LS1 intake?

Well a fast will pick a stock motor up. But I would not spend the money I would do some up grades to the procharger kit like Meath, better inercooler. That just me.

do the ls6 and take a chisel and hammer and take off the ribs , i did it to mine took 10-15 min max , egr isnt needed so delete that when your being tuned.

You can look at the part #'s. You can see this from the top even if the manifold is still on the engine.

97-00 LS1 Manifold #12556333
01-02 LS6 Manifold #12561182
03+ LS6 Manifold #12573572

Used LS6 manifold go for around $350.

Bob at EPP installed my ATI D1 SC in my 98 Camara Z28 which at the time had LT's, 224/228 cam/LS6 manifold, Patriot low compression heads, upgraded 42 lb injectors, and Racetronix fuel pump kit.

Bob installed a very conservative tune and dynoed right at 487 rwhp on his Mustang dyno.

Since then I switched headers to 1 7/8 inch ARH with ARH catted y pipe, upgraded to 65lb injectors, installed a smaller pulley from 4.5 down to 4.38, installed Bob's FMIC kit, oversized K&N air filter, and retuned with an SD tune.

I installed a Yank 3450 blower converter instead of the Vig 3200 and upgraded my stock A4 for a Performabuilt Level III.

I am now at 565 rwhp and it is very conservative tune. With a meth kit (which I have btw (alky control) but haven't installed yet) I could easily make 600 hp.

But I still have a stock bottom end - so for the time being will stay at where I am.

565 to the rear wheel is enough for me and a blast to drive.

As Bob said in an early reply - 500 rwhp is pretty easy to make with a D1. And it should be fairly easy to find a set of 4.5 intercoolers.

IMO a set of 4.5 intercoolers and an Alky control kit is about as cheap as installing an FMIC kit and your IAT's will be much cooler with meth.

And you don't have to hack your front end by removing the front bumper support.

Do it - and have fun
