Default MS3 cam and blower

Ok guys, I just got into my latest 4th gen. love em. car is an 01 SS cam only car, as stated MS3. Not the way I would have gone personally, last one had an f13. But it's fun and I could end up keeping it. Just wondering how friendly this cam is to say a procharger. Not looking for anything crazy. Looking for 500 at the wheels. Would I be wrong in assuming stock heads and intake would be fine? I believe this cam has been run before in FI setups. This is honestly a whole new world for me. But basically I'm bored. Never touched FI. Last car was cam only also. Not looking for any specific track numbers or anything. Fun weekend car with wow factor. Any and all advice is welcome.

What's the lsa on your ms3? I have an F13 which is smaller with my D1SC and LOVE it. Depending on the lsa, the overlap may be a bit much for boost.

That's like 16 degrees of overlap, which is a ton for a boosted car traditionally. There will be boost that will go right out the exhaust instead of making power. So, yeah it'll work, and 500hp is definitely doable, but there are much better choices out there.

No prob, like I said 500hp should be cake, but the car will drive better and make more power if you swap it. If you still want the "cam sound", why not get another F13.

It will make great power. It might make less boost but you will be making more power. Do you want power or a boost number?

Yeah spider, another f13 could def find its way back in. Liked that cam. Like I said this car came with the MS3. Fun but I figured not ideal for FI. Not worried about the sound although it does sound nasty.

Really I just want solid power. Not hung up on numbers. 500 is just a loose benchmark: never had a boosted car. Looking at different options. Not trying to do anything super crazy

It will make awesome power. The more you make NA the more you are going to make with boost. Personally the thing I like about boost is not having to run expensive heads or a big *** cam to make good power. You can run that cam and make big power but if the lobes are to aggressive and the springs are on the edge of controlling the valves before you boost it, you can have a problem when you do boost it. It's not the cams size that would make that cam bad for boost it would be the aggressive of the lobes. Idk what lobes the ms3/4s use they might be mild?

It is exactly the cams valve events that make that cam bad for boost. He's ALREADY running a big *** cam that you just said to avoid. The cam has a ton of overlap so its very likely that he could swap to a SMALLER cam and GAIN horsepower because the less overlap the less boost that will escape out the exhaust. Not to mention it will drive better.

The valve events are fine. I said I like FI because huge duration cams are not required to make big power, Not that you should avoid them. The aggressiveness of a lobe is how it opens/closes. Not the same thing as duration. Yes a smaller duration cam is easier tune. That is one of the reasons I mentioned I like them.

The valve events are hardly fine....16 degrees of overlap on a boosted real street car. Perfect way to have an inefficient setup and blow boost right out the exhaust.
