What can I do to add at least the same amount of horsepower to my car that the scat pack has?

    I have a 2015 challenger R/T 5.7 Hemi. I like it and it’s fast. Just don’t have that umph to it when you mash the pedal. Lol. My question is what would I have to do to add the same amount of ho the scar pack has? Not looking to purchase a 6.4 engine and put in there. Just was wanting to know if there was any mods I could do to achieve it. Hopefully with someone with experience with doing it can help me out.

    Forged internals and then forced induction. I would opt for twin turbo if I had a 5.7. For the cost you could just use that money with yours as trade to buy a 6.4. Keep in mind that with adding a lot of power the support mods add up(brakes,tire, suspension, etc

    you can start off with a tuner. you can adjust settings without breaking the bank aster that , you can add headers and a good exhaust system.

    Would forged internals really be required? The 6.4 doesn't have them, right?

    I was told that you can put a supercharger on a 5.7 with enough boost to make 100Hp and not have to do internals. Also, I was told that you could also leave the exhaust alone. So, I went and got a quote to do this. $10K with dyno tune and all. Would get you right next to Scat Pak power level. So, if you can sell your 5.7 and add $10K to get a Scat Pak, that's one option. Or, add $10K and put a supercharger on for another option. but, like what was mentioned earlier, you probably want to stop better too. About $650 for brake upgrades that won't force you to change wheels. Larger front rotors and police package rear setup is the way to go there. Brembos will set you back over $1000 plus new wheels, because the stock 5.7 wheels won't clear the calipers. Good luck. I'm doing my brakes first, then the charger one day.

    I'm running a S/C with 4.8 lbs boost and have 472 RWHP, the 392 are approx. 476 at the crank.
