Dodge charger RT advice for more horsepower and torque

I posted a reply but forgot this site doesn't allow list spacing. To keep it simple, for small increases you can add exhaust, intakes, headers, and a performance tune. If you have more to spend, you can add a cam package w/dyno tune and all supporting modifications, nitrous (will break things), and gears. If you want to go full out, you can do a supercharger, turbocharger, etc. but you are looking at 5 figures to go that route. The question really is: How fast can you afford to go?

Trading it in for something with more power would be best.

You can always get a higher flowing exhaust & tune. That will wake your Hemi right up. Check out R/T Life on youtube.

If the engine is already supercharged a pulley change could give more boost.
