Most bang for the buck

Good Morning,

I have a 2010 SRT and I"m looking for some mods to do on the performance side. I've put a K&N CAI in but thats it for performance mods. I've heard peiple talk about the InTune programmer but I wasnt sure if it was worth the money or what benefits I would get from the programmer when I have done anything extreme to the engine. I'd like to hear everyones thoughts on things as I know about enough to get myself into trouble but want to see what people have done and also what they recommend.
Thanks

i have a 09 srt

got a intune.
magnaflow 16885 comp exhaust.. gonna get a cold air intake soon.

ALL OF THIS COMBINED.. MIGHT get you 20hp.. mine is a 6 speed so you don't notice things as much as you will an automatic. the intake is mainly sound and eye candy. the exhaust is sound.. the only real gains i see so far is from my intune.. again. this aint gonna set the world on fire.

the intune is fine or the trinity.. either one. intune is cheaper.. smaller and has a couple less features but if you arn't a racer i don't know if the trinity is nessisary or not.

is your car a auto or 6 speed?

Let's assume the HP gains are after you get your custom tune. Here is what the HP gains might look like, per item:

ported throttle body (5-10hp)
catback exhaust (5-10hp)
long tube headers (15-25hp)
high flow cats or cat delete midpipes (15-20hp)
aftermarket camshaft (40hp)
higher flowing heads (35hp)
CAI (a good one like Legmaker or AFE) - (10-15hp)
Custom CMR tune (will need a Diablo Intune for this, in order to datalog and adjust a/f for mods)

TOTAL HP GAIN : 155 rwhp. (With this number I am going with the higher estimate values I posted). Now that, to me is a lot of power when fully completed. And, all naturale. No forced induction.

As far as where to start. Most folks open up the intake and exhaust with a good cold air intake, and catback system. You won't really see gains on the exhaust until you replace the stock headers with some long tubes. Catless may not be legal in your state, but they can yield the most HP gains. A ported throttle body will give you much better throttle response, and the larger opening will be important once you are pumping in more air into the motor. You may be able to go this far without a tune. Obviously adding the more aggressive camshaft and heads, you will need a custom tune. Exhaust will cost a lot, as will the installation and purchase of the heads and cam. Some of the other items aren't that bad. Mods work as one big PUNCH, it's not just one mod, but how they synergistically work together as a whole. The more mods, the more gains. If you want quick and easy power, you just can't beat a supercharger.

I am not an expert, but I've researched it a bunch and have a friend who has a '10 SRT which is pretty jacked up. He doesn't even have an aftermarket catback, but it still sounds mean with the cam and long tubes.

That would actually make for a good sticky thread.

The reduction in torque management alone is worth the price of admission, the extra power, increased throttle response, and improved shifting on Automatics is icing on the HEMI cake.
Hate to be that guy...but any word on when 2013 tuning might be available?

I'd do the tuner first, then I'd say a super charger is going to give you the most bang for the buck. You need the tuner to use the super charger anyways so you might as well get it first.

2014 SRT Core - 12.285 @ 112.50 mph
2010 R/T - PB 12.87 Traded

I know my car runs 10's because I once beat a guy who said his car runs 11's.

After going through the naturally aspirated route and extensive mods with my 2010 SRT, I would say...

Save up, supercharge, and be done.

I'd recommend just getting a blower or stroker and making some real power rather than all those bolt ons which won't do much but add up to real money
