I just read a post that shocked me...and frankly got me a little excited. A member named "Kevinas" something or other stated that he was making almost 240hp (50+ over stock) with basically just a full exhaust, intake, MAF and 65mm TB. Are these typical gains from such mods? If so, I'm ready to start modding!

Also, I know it's hard because the effects are cumulative, but can someone give me an idea of which of these mods are responsible for which portions of that 50+ extra horse?

Also, would all of these mods create a stronger low end, or would you be trading low end for top end? Thanks fellas.

 

yes sir

 

Twisted, It is very possible for a strong 5.0 to make that kind of power with a swapped intake manifold, TB, full exhaust, and timing advance. For instance, The shop car for Pro Mustang performance makes about 232 rwhp with a professional products typhoon intake, 70mm professional products TB, unequal length BBK headers, CATTED H pipe, and Borla side exit exhaust.

Now, we know for a fact that his exhaust is holding back a few ponies, and this was also untuned...

My personal car (yes, i realize its a Cobra) makes 276rwhp with TB, UDP's, Full exhaust, CAI, and 15° initial timing. I have posted this just about everywhere too. my car made 253 with an air fuel ratio of 15.5:1, and now runs in the area of 12.8:1

The problem that people are having with their cars not making HP is that they expect every little part to make a difference, and everyone is changing out the wrong parts. I hate to break it to you guys, but changing your MAF isnt going to give your car HP... i tried it with a lightning 90mm.

Everyone likes running huge MAF's and semi small TB's. Yes, the cobra intake does accept a larger TB than a stock intake, and i do have a different H/C/I than most. BUT... I firmly believe that a set of equal length headers, offroad x or h pipe, and some nicely flowing mufflers (NOT FLOWMASTER.. ill explain), a 65mmTB, 65-70mm maf(buy a stock sn-95 maf and swap your electronics onto it), CAI (i like my ebay one, everyone said it wouldnt fit... but it fit like a charm), and advance your timing a little bit. you will notice a difference in how your car runs over stock, however it may be neccesary to buy an adjustable fuel pressure regulator so you can do some DIY tuning at the dyno.

and to explain about why im so anti flowmasters... i swapped a set onto my car at the dyno (dumped of course, only 4 bolts to swap in and out) and my car had a loss of 11hp

so i now swear by my mac pro dumps (did you know that tailpipes actually restrict exhaust flow, and cause a loss in power???)

 

Thanks fellas...and thanks, Adder, or all the great info. I didn't know Flows were so restrictive. I guess I'll start planning to start with a full exhaust--I feel like that will be the most enjoyable mod to start with. And I am fully hip to not going too big on anything, as I hate losing power from mods!

 

The car runs super with all of the mods that i have done...... and I believe all and all that I spent around 2K for all of the bolt ons that I did... But i am still at a high 13 or low 14 with all of these mods. SO.... the next on my list is to get heads and cam.
OH by the way I am taking the stang out tonight with camara looking for victims of the new Nitrious set up I did
