Default SC help

From all of the product postings and various posts on here I have read people say the SC's pick up a percentage of hp. Usually around 50%.
So my question is. Is that base hp or overall? Meaning if I do a cam and that picks up 50rwhp. Will the SC pick up an additional 25rwhp?

Thanks in advance,

Supercharger forces more air into the engine. If it forces in twice as much, you make roughly twice the horsepower. Its almost never an exact HP number. You can make anywhere from 0% increase to 200% depending on how fast you want to spin it.

Hmmmmm okay. So Would it be worth it to do a cam then the charger or does it matter?

Thanks in advance,

A good blower cam will add some power, but a cam for n/a applications would not be worth it. IMO, either get a cam suitable for your setup, or just stay with the stock one

A good blower cam can have huge gains if specd right.

I am only planning on running 6-8 psi through it. Wouldn't I need to run more boost through it to really see the benefits of a blower cam? Not that I wont turn it up. But for now I think 6-8 psi seems safe for a stock motor. Is 6-8 psi a safe amount to run through a stock motor?

Also if I was going to do a "Blower Cam" what is the difference between that and an NA cam? Could I get a cam that runs well both NA and with the charger?

Thanks in advance,

I've had quiet a few customers order and install my blower cam prior to adding forced induction, and a lot of them have picked up around 60hp with it.

8 psi with a good tune is generally considered safe on a stock engine. Bob

Great I will take a look. At first glance the Lift and the Duration is similar to the "NA" I was looking at the main difference I saw was the Separation. Why does this cam have 115 lsa? Does the separation have a lot of impact on forced induction?

Great! I was thinking the stock block can handle 8psi. Do you know what kind of gains is rwhp I could see pushing psi through the motor?
Also I planning on doing bigger injectors and a better fuel pump. Any suggestions? I was looking at 60lb injectors. Are those big enough?

Thanks in advance,

At only 6-8 psi you could definitely pick a cam that would run well either n/a or blower. My buddy runs a 228r cam and it worked great for both applications

Correct, you don't want to lose a lot of boost out the exhaust valves.

8 psi along with my cam will generally get you 200 rwhp.

I'd go with 80lb injectors, price is about the same and they provide a good idle.

Thanks. Bob

Obviously this will depend on the supercharger and how much air it can move.

So at what point boost wise would a blower cam make a difference in comparison to an NA cam?

I don't think I will run more than 12lbs through the stock block. I don't even know if it is safe to make that much on the stock block.

Would a Magic Stick 3, 238/242 .600/.600 114 110 lsa, be an okay cam for NA then a blower?

Thanks in advance

If you're talking a stock LS1 block, you basically have the weakest production block.
8 PSI should still be fairly safe, and will show roughly a 40-50% power gain.
12 PSI would be closer to a 75% power gain.

Any cam will work, its just that some are much better suited than others. You can run the MS3 no problem, but it might be worth it to upgrade later to something that will perform better with the blower.

I'm not completely sure but I'm willing to bet a blower cam will make more power at any given psi. I'm just saying you can do a more mild type n/a cam on low boost levels and still do just fine. Like mentioned above, you could run that MS3 cam at low boost, but anything more than that it would not be a good choice

My thinking is doing a cam is way cheaper than a charger right now. Could I do a decent blower cam then drive the car around with just that for a while? Or would the car run like trash/very similar to running on the stock cam?

No a blower cam would run just fine for now, and still provide some gains over the stock cam. Basically you have to decide what you want to do now, so you don't have to do it twice. Know what I mean? The vendors on here can spec you something based on what you have now and for your future goals. But i will say stay away from that MS3 cam if you plan any boost at all. While it may run ok at 6 psi, it's gonna be a bit harder to tune, and offer no ability for any further growth with the blower
