New Mopar man. Where to start

This is a learning process for me so any help will be much appreciated. I bought a 2014 SRT8 challenger. 6 speed. It has a loud mouth exhaust on it but everything else is stock. Sounds great. I've had many sports cars but this takes the Cake I want to put a cold air intake on it. Maybe a bigger throttle body and spacer. I've never done anything with the computer as far as a tune. And I don't know where to start. I want more horse power. I guess I've become a Mopar man now. Lol. So please tell me where to start.

Welcome aboard and congrats.


CAI's won't up the HP. They cover looks and sometimes up the intake sound.


Forget about Spacers. Worthless on a Hemi.


Larger throttle body? Others may comment on success with these.


I would suggest starting out with a custom tune from Hemifever.


Any other "power adders" would take digging into the engine, and you're taking BIG bucks.


Best of luck with your new ride

Like previous post said, intakes are good for looks and sound, so up to you if you deem it worth 300 bucks.

A tune on a mostly stock 392 won’t give you much more than 10-15hp/torque. Especially on a manual car, it’s not going to be that noticeable. Auto cars do better with tunes, just because you can alter the manners of the trans.

If I were you, the first thing I’d look in to is a Barton shifter and some bigger rear tires.

If you want to blow some cash, longtubes, cam and tune would be a good route. From what I’ve read, these motors don’t like boost.

Get the Volant intake with the Donaldson power core filter. I bought that because the Donaldson media filters much smaller particle size.

Dont know if it adds any power. To me the car is plenty fast and sounds awesome with the active exhaust.

I am also a new owner, of a 2015 R/T Shaker Plus. I want to also up horsepower and improve performance. Any suggestions would be much appreciated.

Barton shifter and clutch delay valve delete should be the first mods to do for a M6 car IMO. CAI just get any one that you like the looks of, they are all about the same. And as for the exhaust everyone seems to have a different opinion on this, for me I did resonator delete and sounded great when my car was stock. I am far from stock now.

I have an auto so I don't need to bother with the clutch, but I thought the Shaker comes with a CAI? I am not 100% sure but I thought I saw that somewhere.

All of the CAI won't help may be correct, if on a stock 392 engine. But, if you do other things, then they may help depending on the CAIs ability to flow more air.

Spacers are snake oil.

Larger TB on a 392 may help, especially if combined with other changes. However, the intake inlet must be ported for the TB to achieve any gains.
