Not many mods worth the $ on these cars?
I still have that POS oem shifter with zip tie. I saved all that for when I swapped to the MGW. I look at it every so often and laugh.
Yeah,...if you wanted to keep it N/A definitely. Go with a GOOD intake, a GOOD L/T header/full exhaust, a GOOD cam and some NICE high flowing heads and you got yourself a little beast. Don't forget suspension to get it all down to the pavement.
Nothing's cheap, especially the good stuff. If you want to play, you got to pay, unfortunately.
Thank you.

The stock intake and manifold are just about as good as anything aftermarket...buying a CAI is $300 down the toilet.
The stock exhaust offers no low hanging fruit. Yes, you can pick up a few hp with a full long tube "off road" exhaust system but have you priced out these systems yet? Also, those which omit the catalytic converters are illegal.
The stock heads ARE good heads. They flow incredibly well. Do you know of significantly better than stock aftermarket heads? Again, these are going to hurt the wallet for some minor gains.
The stock/variable cams (and there are FOUR of them which your comment seems to ignore) cover a very broad spectrum and are quite agressive at the far end.
So,........there's no way to stay N/A and boost power and tq. on a 2013/2014 Mustang? Is the only way to add power is by forced induction? (I'm not being facetious, I'm seriously curious.)
I'm still learning the Coyote engine.

OK... just stop now.

As far as long tubes go you are looking at about a 15HP gain and about 23-30 with O/R pipes. But you know we don't do anything illegal to our cars such as axle backs, corner tints, hell even the quad pipes are illegal if you changed the baffle out for a larger opening or even removed completely. IMO the sound alone is worth the price for long tubes and the added power is a bonus. Unfortunately in order to retain our side pipes we have to go with someone like Kooks where it is roughly $1200 to go with Long Tubes.
The majority of the added power for the Boss was made from their heads with the rest coming mostly from the Intake Manifold and then followed up with the exhaust cam. I'm not saying that the factory heads aren't great because they are and they do flow pretty well and people are making monstrous power with them. Cams are a whole different story here, there are so many options here that you can pretty much customize them to whatever your setup is and optimize it to make the most power you can out of the setup.
I know previously driveshafts were mentioned and how they really weren't worth the $600, honestly .1-.2 and IIRC 3MPH certainly seems worth it to me. Again when you can spend 7k and get roughly an additional 170HP spending 9 or 10k and getting an additional 140HP (and that is on the engine alone)
So it really all depends on your definition of what is worth it. Me, personally I am a N/A guy so I am willing to spend the money to get 520HP. I would love to see what kind of block the GT350 will be using so I can use that and a set of worked over 2015 heads on top of an All Motor build.
If you want to make power N/A you can't be afraid to rev the motor to the moon, it was built to tolerate and handle it. You just have to be prepared to do some research and figure out all the pieces to the puzzle and put them together.
No, there are plenty of ways to make power N/A and there are some N/A cars that would put a lot of FI cars to shame because those people took the time to properly setup their cars. JPC has had one of their cars in the 9's there are a bunch of guys in the 10's and a lot of guys running mid to low 11's. There are a bunch of guys running coyotes that are making 500HP without using heads.
I would agree that most of the cheaper mods don't offer much bang for buck from watching and listening over the year. When it comes to adding more smiles to the car, totally agree with suspension and sound. Loving my gt500 ab's and better suspension. The stock engine still surprises me regularly.
It's like everything now...if it's cheap and claims big power gains. It's usually too good to be true. But you can make plenty of power n/a if that's they way you want to go. Sure it costs money. But so does a blower/turbo kit. If you don't want to spend money to play then leave your car stock. Power isn't everything. Just look at the numbers the mustang runs with relatively few mods. Just look at the mods this guy needs on his Camaro to run an 11.7-11.8...most auto Coyote's run faster than that with just a converter, tune, h-pipe and drag radials.

Look into Nitrous Oxide. Press a button...go fast!
Perhaps it's a good thing that the days of easy power are gone...but if you're looking to improve the acceleration performance of your Coyote powered Mustang, disappointments abound. Some of you guys who have already dropped money on these mods will likely disagree...but without hard numbers, don't bother. Butt dynos don't count.
If you do have hard numbers, your results are most welcome... but the following is what I have gathered over the past few years with my 5.0 Mustang.
I'd welcome being proven wrong on any of this.
CAI- total waste of money, almost no improvement over stock, 95% of benefit comes from associated custom tune profile
Tune- some ganis to be had, some will apparently STILL wreck your engine (#8) and there's no way to tell which are good and which are bad. Too many variables, small sample size, people defending their purchases, brand loyalists, and interruptions from the vendors/forum sponsors themselves.
Throttle body- waste of money (unless you're going FI?)
Headers- minimal gains, expensive
Boss intake- loss of torque, only benefits if you change redline- probably not wise if you plan to keep your car past 50k miles
Off road X/H pipes- small gains- illegal, tickets are expensive, irresponsible. Everyone driving behind you can smell the fuel
Other exhaust mods- noise only
Driveshaft- some weight savings but the benefits to reduction in rotational mass is overstated, expensive for minimal performance gains
If you want to go faster in a Coyote powered Mustang, it seems like you should just save your money for FI and not bother with anything else.

I happen to agree with MRGTX. Mustangs are great cars because they fit so many different purposes. First off they are good looking cars (Camaro-Ughh) and the options available are countless. Some use them for their DD some to take to the track. I think the point is that if you want to get serious HP you have to "pony" up the money for it (ie FI). I got mine as a toy and have made some cosmetic changes (lowering, grill, exhaust) but that is just one more thing that makes them great cars because there are SO many different options out there. But eeking out a couple more HP at the tune of hundreds of dollars.....pass. Doesn't mean I am stopping on making other upgrades, MGW in near future and some other cosmetics and suspension. Now when my warranty has expired and I have saved (hidden from my wife) the $6-7k for FI....oh yeah, I am there.
Where has this conversation gone? 11 second n/a coyotes are all over the place, are any of you complaining about mod cost effectiveness actually going to the track? These cars n/a are dominating with bolt-ons and slicks. Is it cheap? No. Is it worth it for those that truly aren't in a position, financially, to toss money at a car that doesn't give away horsepower easily? No, no way in heck but please don't take a "mods aren't worth it stance" ESPECIALLY those with no f'n mods... it just makes you look silly and bitter because you don't have any.
Same ol' same ol'... gotta pay to play and with the coyote, the return on investment isn't great buy hey, we are blessed with this car any way you look at it.

Near 10 (11.037) second n/a car on the stock block/tranny/rear-end/etc. and it's a manual, an auto would be in the 10s all day.
Bolt-ons aren't worth it... Yeah.

Agreed
Whether a mod is worth the cost per gain is subjective and depends on what the individual wants from his/her car.
Someone like myself who uses the car as a DD may not want to add mods that take away from that daily experience. But enhancing the overall experience is another story. Axle backs, Shifters, Tunes and suspension are mods in my book towards enhancing the driving experience. Notice that big power mods aren't on my list, this is because I choose to make the car capable of using the power it has before adding more.
