I'm looking to procharge my ls1. My cam is quite large, definately an n/a cam. 242/242 .595/.617 112

I'm am shooting for just 500-530 rwhp. How will this cam affect the boost? I've heard of the larger cams bleeding off the boost and such. With this one having 18 degrees of overlap, i'm sure it will do just that. However, with my power goals in mind, how badly will it really affect it?

One other question, what supercharger would you recommend? I'm thinking the p1sc will be plenty with my lower power goals. shoot, the 600b may even work. Thanks in advance

D1SC..


I would say the cam is too big....but some might suggest it could work well.

Either way, slap a blower on, and you will still get good results, dont worry about that.

Any cam will 'work' with a blower, some better, some worse. Try it and see.

I wouldnt bother with anything less then a D1SC, its a lot easier to slow down the D1SC to work then try to spin the P1SC faster plus you have a little extra reserve - that 500rwhp goal will be easily acheived and you will want more. But if you find a deal on a P1SC I wouldnt pass on it, it can make 500rwhp pretty easy. There are different P1SCs as well, the ones they use in the LS1 (p1SC-1) kits have a better impeller. P600 isnt self contained if I remember so you have a little extra effort to get it to work and with the low step up you are going to have to use an aweful small blower pulley which may cause problems.

Isn't that the truth...lol

I'm trying to find another kit that I can use and then just buy the bracketry. My kit has to be custom anyway except the f body bracket and the head unit. Although I'm learning now that there are reverse rotation and normal rotation head units... Thanks for the advice/input guys, I appreciate it.

There are standard and reverse units plus they are clocked different internally for the oil slinger so be carefull when buying used.

?Yeah that's what i was told. I'm not sure how to tell unfortunately. Is there any sort of way to identify how they are configured?

Drain plug will be the bottom, fill plug on the top for the slinger. Best to just buy one that you know was used on the brackets/car you want, sometimes people end up with head units and they dont even know what they are for so its best to be careful.

I'd keep the cam, and see what happens. What kind of midrange power does it have, does it need a lot of converter or gear?

Cams are like little recipes, and each change will change the overall characteristics of power band.

And it would be great info for the rest of us to see how it performs

For those durations and LSA, there is going to be a lot of overlap when both valves are open. I think it will be pretty hard to hit 500 rwhp with that cam and a D1.

The cam has 18 degrees of overlap. N/A it is roughly 410rwhp. I would think a p1sc would get 90 rwhp, even with boost bleeding from the overlap. I'm still trying to find out how to tell if it's reverse rotation so anybody that can shed some light on that subject would help a ton! Thanks!!

Bump for being on the second page so quickly lol

PM andereck he works for ProCharger.

I ran a 236/246//114 with my blower and it worked great, but I had a 4500 converter and it hit pretty hard.

I bet you have a strong midrange and maybe peak a bit lower than some of the other stuff out there... But might run faster.

i've heard a bit different about my cam. Saying that i should spin it till 7k, which i'm not doing jsut yet. I'm not too worried about down low, my car is so light that rediculous power down low would be worthless. Thanks for the input, i will get in contact with him
