Looking to get some thoughts and help with a cam. I have a complete 6.2 l92, I already did the DOD and VVT delete and installed a pretty big cam
236/248 .601/.615 112LSA

Just got a good deal on a PISC complete kit. So I'm thinking my cam won't work, got any recommendations for me? Not looking for crazy big HP just some bumpy and decent power.

Btw anybody got any ideas what this combo will make with a decent cam for HP. Torn on wether I should even buy the blower at all.

Im thinking the p1sc is a bit too small for the engine and cam and will have to be spun close ot max rpm to get any decent boost out of it. What elevation your at, the intercooler setup, and the drive belt setup will be a factor on output also ie " sea level with a FMIC and a aster setup vs 5000' elevation, the small 3.5" twin intercoolers and a slipping 6 rib setup. It should still be able to make 600rwhp or more when maxed out though. Im no expert by any means just my thoughts.

I was worried about that also, D1 would be a way better option. But at $2500 for a full kit. It's the entire kit that Procharger sells for the 6.2 motor, I would run 60lb injectors. Standard 6 rib and a Katech tensioner. Not looking for huge numbers but if it doesn't put down 500 I will not buy it, hell I can achieve 440 with my cam

Is the head unit a p1sc1 or p1sc? If you were at or near sea level Id say you could make 600-650 with it maxed out but IDK what elevation you are at.

So are you assuming I can get away with keeping my cam and run a small pulley? Run some 80lb injectors. I'm in Phx

With your cam and if it is a P-1SC and not a P-1SC-1, you're going to have to really work the blower hard at your 1100 ft elevation, but it will work. You should easily make 550 rwhp with your cam and head combination. I'd start with a 3.40 blower pulley and see what it does. Bob

Stock L92 motor with my cam and headers and this procharger P1SC all through a T56 should make 550hp??? If you guys feel it can be done I will goahead and buy it. I would just be pissed if it didn't even hit 500lile I have seen on many other 6.2

It is a P1-SC-1

P1-SC-1 is a good head unite.

Back in 08 or 09 we took an 08 Corvette with an LS3, added our blower cam to it, and a D-1SC. It had Kooks headers and Kooks exhaust on it. At 8.4 psi it made 700 rwhp with 18 degrees of timing and somewhere around 11.5 air/fuel. We pulled as much timing as we could out of it and it still made 685 rwhp. We told the customer we needed to go to a larger pulley on the head unit to lower the boost, but he wanted to leave it as it was, saying he never shifted above 5000 rpm. You're going to make power!

What size injectors should I use 60 or 80?
Also do you feel I can leave my current cam in?
My old vortech sc car had a boost a pump on it, can I get away with a big walbro in tank and not do a bap?
Can I rely on the tune for adding fuel under boost, not sure how that works.
The kit I'm buying was installed on a 08 Escalade for 2500 miles so its like new. Thanks for the help

I would go with the 80's for sure. 60's may work, but the 80's will for sure and leave you a little breathing room.

OP was I was curious about my big N/A cam and could I keep it with the P1SC1 setup?
I will upgrade to 80lb injectors and maybe a Vic Jr. with a Edelbrock elbow just for more clearance, I have plenty of room height wise, just limited on engine to rad space... So if I turn the elbow 90 it should help.

Just really curious if my cam will work so I don't have to rip the motor back apart?? Thanks for the help

The 60lb injectors will do the job but as Rise of the Phoenix mentioned, 80lb injectors will leave more to offer. 80lb injectors are about the same price as the 60's.

Yes you can leave your current cam in the engine, it will work.

Yes you can go with a Walbro fuel pump in place of the boost a pump.

Yes, getting a tune done will handle adding fuel under boost. I'd shoot for an air/fuel ratio of 11.5/1 above 5000 rpm, and normally backing the timing down to around 18 degrees above 5000 rpm takes care of avoiding spark knock.

You're welcome. Bob

You will see 600 at the wheels when you spin that bad boy up. What size crank pulley are you running? If it is the 7.5" you can go with a 3" headunit pulley from 928 Motorsports to get to max P1SC RPM. Have NicD tune it since you are in Phoenix. He is the best around, google NicD to see his website/contact info. He can do a speed density tune that will add fuel with boost based on manifold absolute pressure (MAP). Definitely go with 80's.

Bob@BruteSpeed

I doubt he's going to want to drop down that small on the pulley since the head unit is a P-1SC-1. Bob

I run a 3" without belt slippage (the 928 pulley is much better machined than procharger pullies...) on a P1SC1. Doesn't (7.5/3)*4.1*6500 RPM = 66,000 RPM for the head unit vs. the 65,000 limit? I guess I felt like the extra 1,000 RPM is OK...but I am assuming he is only running up to 6,500 engine RPM.

Bob@BruteSpeed

How much boost are you seeing? Bob

JoeMama's GTO

iTrader: (3)

12 psi when it is cool out and the boost remains linear to redline. That is how I know the belt doesn't slip up top. Car makes 599 RWHP on a dynojet in "warmer" conditions; about 80* and high humidity.
