I went from 372 stock to 418. Have CAI, off road h-pipe, mufflers and a tune. Have run a best of 11.89 @ 119 with a set of old drag radials in the rear. Could probably cut some more off. The 60' was only a 1.88 on that run.

 

I bought my car as a toy. It's not a DD. I just wanted a fast, fun car for the street. I'm not into 1/4 mile runs so most mods are not for me. I'll never use all of the factory HP so I'm not really interested in adding more. I added the Roush AB purely for the sound and not because I expected any HP gains. For now, the rest of the Mustang in factory trim is fine for me.

Snow tires if you live in a place like PA are worth the weight in GOLD.

Intakes are dyno proven (not butt dyno) to increase hp, sooo not sure how you could disprove that.

If you care at all about handling a watts link is a worthwhile upgrade, theres alot of room for improvement in the suspension

Alot of the things that people do are worthless, like putting on bigger wheels, or spring swaps, cams which rarely are tuned for properly. I can understand the hesitance towards tuners because there have been some issues with those.

 

Only from the companies selling intakes. Independent dynos show that cai's gain next to nothing vs the stock air box. The gain is all in the tune that is required with a (most) cai.

 

11.76@119 my best ET to date at full weight. I don't launch the car and I'm not that great at leaving the line. Run regular 11.9s easing off the clutch while holding at 3000 rpm and rolling to WOT as the tires chirp, shift light set at 7100. I'm sure ET radials or slicks would knock off a few more tenths to a half second.

As I recall...most runs it was over 90 degrees at O'Riley and the DA is almost always over 2300'.

Stock was 13.1s
Steeda Tune, CAI and shifter = 12.7s
NT05 added = 12.4@117 note these are the 275 street tire, not the DOT-Rs.
Tokicod, Springs, Control arms =12.1s. Average but best under 12.
Driveshaft. 11.9s very consistent but some under 11.8

The NT05 made the most improvement of my poor launches and 60' times which still need improvement and a shift light improved shift point consistency which helped keep most of my runs stay within 2/10ths of each other.
Now I have 295 rear tires -NT05Rs - so maybe we'll see better.
Not sure if the sway bars helps but those were added same time as springs.

Spring get here soon

 

well i guess the last 4 cars I owned that all had intakes and made more power on the dyno vs stock were all statistical anomalies....

 

What were the previous 4 cars?

 

2007 Cobalt SS Supercharged
2002 Cavalier LS Sport (supercharged)
1989 Turbo Trans AM
and of course the stang

 

Not at all - like it's been said earlier in this thread, this gen of Mustang has a very well designed stock intake that is hard to beat without a tune.

 

Exactly. No one said intakes don't add power. On my RSX a cai added 18whp with no tune.

What we said was it doesn't add much if any on the current gen mustang w/o a tune.

 

The difference is the MAF has to be recalibrated to take advantage of the larger area that the CAI gives you on the Coyote cars. This will add some HP but not what most would call significant enough to warrant the added cost of the CAI.
Also all dyno runs with these intake setups are done with hoods open giving them the advantage of more fresh air then they would have in a real world scenario. I remember reading threads about IAT's (intake air temperature) in CAI cars being much higher then stock. Yes they have heat shields but how effective are they really ?
So this begs the question of did I just spend $350 for a CAI to suck hot air and make little to no gain vs the factory setup ?


We all can weight the pros and cons of whether a mod is beneficial or not for ourselves... just wanted to add my $.02

 

The only cai I'd consider one day is the aem. It uses a dry flow filter and is fully enclosed with a scoop just like oem. It doesn't require a tune because the tubing is the same diameter. It also doesn't gain or loose power. But it looks amazing and matches so well it could have been factory.
