LSA Supercharger Stock Cam vs LS9 Cam

One of two things will be happening in the next couple of months. Either I will be selling my SS for a Hellcat, or supercharging the SS. I've wanted a Hellcat since they came out, but I'm having a hard time as to whether or not I want to part with my SS. Every time I think I want to sell the SS and am about to, something stops me. I don't know if it's the rarity of the car, or just how enjoyable the car is to drive and toss around combined with how spacious it is. I can't really put my finger on it, but I like this car A LOT and never had such difficulty in deciding whether or not to sell. Posted the car last night on cars.com, got a hit already this morning and am second guessing it again.

Anyway, if I decide to keep the car, I will be getting an LSA kit installed on the car. I don't want to change the cam BUT if I did, the only one I would consider is the LS9 cam. My question is, how much additional power would be gained on an LSA-ed car with the addition of the LS9 cam? Is it worth throwing it in there, or should I not even bother? I absolutely LOVE the way the car feels and drives now, I just want more when I really put some pedal into it. I know you lose some low end with the LS9 cam, but the LSA with the instant boost would probably remedy that. Current mods on the car are ARH 1 7/8 Long tubes, high flow gesi cats, x-pipe to stock mufflers, Roto-fab and ported TB.

Why would you go with a stock cam when you can go with any thing else ? Owner of lsa and ls9 engines replace them for more power so why outdoor you limit yourself. Im not saying go for a max effort style, but choose something to suit better than a stock grind.

Because I don't want any lope or chop. I want a stock idle, no bucking or surging or much alteration in the torque curve or power delivery. I just want to simply raise the power level up without changing the curve. From what I gather, the LS9 cam doesn't change much when adding an LSA, just increases power. I'm just wondering by how much.

The Brian Tooley stage 1 PDS cam is pretty stock sounding in this video. The video LS2 is 6.0 L when the LS3 is 6.3 making the cam "smaller". It was developed with positive displacement blower valve events in mind. Your long tube headers and intake have already made the car sound far from stock any way.

It does sound very tame. Reminds me of the Livernois 1C and the Lingenfelter GT11. Its the additional lift that worries me a bit. I'm not going for max power, I just want more of the same. Whatever that ends up being, I'm fine with (I'm thinking in the ballpark of ~550 rwhp with 8/9 psi). The ONLY reason I even considered the LS9 cam was 1. because it's completely audibly undetectable to my understanding, or detectable while driving and 2. Being a factory cam, it was designed with years of R&D behind it to be reliable with a warranty with a certain set of valve train components (which would have to be changed obviously with the swap). The cam decision isn't the big decision I'm trying to make, I'm basically stuck between supercharging my SS, or selling it for a Hellcat. I wish I could just buy a Hellcat and keep the SS, but the funds don't allow for that.

While Dodge has made the interiors of the Charger's nicer over the years, I think it still looks pretty boring compared to the SS. I'd much rather have the SS for the suspension also. The Charger is a good driving car since it's based on an old E-Class chassis but it is far from the best handling car out there.

I drove a Charger Hellcat and it drove fantastic. Extremely quiet, smooth a refined, more so than the SS, which was the opposite of what I was expecting. You close the heavy door, and it sounds like you hit the mute button to the outside world. It drove like a big luxury car. The interior was a bit too rental car like IMO, meaning the center cluster of buttons. The Challenger interior nicer IMO. Much cooler layout. If I were to trade up, it would be for a Challenger anyway.

If you are central PA feel free to take a ride in my car. It has a LSA, after market cam, lots of “more”. Idle is great, zero drivability issues.

Thanks for the offer. I’m on Long Island, I’m not that far but not that close either. If I’m ever in PA I’ll PM you.
