Default A few more horsies for the Mustang

As many of you know, I bought an '07 GT back in July (22K miles!) and have been looking at some mods to get a little "more" out of the stock 4.6/300 motor.

Looked into a RoushCharger first, but that was a little much off the bat (AND about $6K!).

Got hooked up with a GREAT "local" performance shop (99% Mustang mods!) and 1 of only 2 dynos in the Richmond area.

Back on Oct. 4, I took it over and got a cold air induction (Steeda Pro Flo) to get me started, along with a "flash tuner" (SCT X3) with 2 preloads - 87 octane (street) and 91 octane (performance).

Took about 2 hours, including 2 dyno runs (before/after mod) - I was scared they were gonna' HURT my "baby" on that thing!

With the second dyno run, I gained about 19RWhp and 20ft.lbs.. I thought that was "o.k." ;?, 'til the tech took it out the driveway and it "chirped" 2nd gear (it's an automatic) before he got about 200ft. to the "STOP" sign!

He then let me take it down the street and it did it again when I got on it! :thumbsu p:

I can NOT believe the difference in the performance with just these 2 mods!!!!!!!!!!!!!!!!!!!!!! It ran GREAT beFORE but WOW - now it feels SOOOOOOOOOOOOOOO much "stronger" - it wasn't just the CAI, but that "tuner" frees up a lot of the computer "telling the engine it wants to go SLOW" crap! Runs "stronger", shifts are more "positive", "sounds" a little "beefier" out the pipes, etc.! Excuse me for "gloating" a little, but I've never owner a "performance" car before!

And I just have the "street" tune loaded - haven't run the gas down to get the 91oct for the "performance tune", yet!

I also had the shop quote me from new headers back to the mufflers (and in between!), as well as 4.10 gears (I think it has a 3.27 rear now?).

What I had done is probably about the cheapest bang for the buck, and is usually a "starting point" for similar cars. I can see how this "mod" thing can be VERY addictive!!!!!!!!!!!!!!!!!!!!!!!!

Anywho, here's a couple of pics of the mod - although most of you speed freaks have seen this stuff MANY, MANY times before. Bear with me.

Thanks, again to ALL who commented before on the other thread I started and I'm still going through all that stuff in my head!

If its gonna be a daily driver or driven on the highway dont go with the 4.10 gears you'll be revving that motor at 4k at 55-60mph the perfect rear of those cars is a 3.55, also a few other things to look at for modifications is an under drive pulley system you can add about 20 more hp by doing that, also if you go with a new exhaust go with an off road exhaust I had it on my stang its the best sounding you can get also try putting in some bigger fuel injectors you will see a very big difference in performance also, Good luck it can become very addicting

Bruce why don't you take your gig money and the money the women stuff into your G-string and put it into your car? In no time you should be driving a Pro Stocker.

Welcome to the club. And oh, remember 4:10's (which is a good starting point) do absolutely nothing for putting Horsepower under the hood. And if I've seen it once I've seen it fifty times where the high gear causes the car to break traction which in turn causes the car to turn a lower ET. There is nothing wrong with going with the taller gear, but you will probably have to do some suspension mods so the car can lock into all that tire spin.

Congrats....I am currently driving my first "performance car" too (getting married and buying a house at 21 meant toys were not an option). I too have added a CAI, performance tuner, and a lower termostat to mine.....but I started with a 425hp Charger SRT-8. Get the gas out of that thing, add hi-test, and see if the shop will make a custom tune for the car. That's the only other thing I did (done when the car still had 30 day tags on it!). They were able to pull 396 rwhp and 400rwtq on the dyno (calculates to 495hp at the motor). Mine is an automatic too yet hits second gear kicking the azz end of the car a little sideways. Went to the track right after the MODS were done and pulled a 12.9 @ 110 .
It IS addictive, and I would add more but the car is leased . I'm starting the think I might add a little and just buy the car when the lease is up.

...and Bruce. What shops are in the area? When I first got my car I had found a Charger specific forum and got hooked up with a club in hampton roads (where the dyno/tuning was done). If I do any additional work I'm just curious who the local shops might be.

bellsisland, I'll send you a PM as to not hi-jack BruceW's thread.

Congrats on the mods working out so well. I have a 2010 Camaro SS/RS/M6 and have also added a CAI. I noticed some difference in HP with the CAI but not as much as I had hoped. I was also hoping I would be able to hear some kind of a "growl" from the CAI but I only hear a little sucking sound. I started out with 426HP and the CAI was supposed to add about 20HP. I thought about adding a Loud Mouth exhaust or a Borla exhaust system but I didn't want to listen to the exhaust drone all the time. I ended up buying an exhaust cutout system from Quick Time Performance (QTP): http://www.quicktimeperformance.com/QTEC/index.php

I bought the control module that has a digital read out of each cutout and I can adjust it from 10% open to 100% open with the push of a button. I am SO glad I went this route, just simple things like going through a fast food drive through, it's hard to hear when I have the headers open, so a push of the button and they are closed. It's also great when you are trying to talk to someone and you can close the headers. I'm sure with the 440+HP I have now, when the headers are open would break all noise restrictions and I would be paying tickets. I see a cop I hit the button and the car sounds like it did when it rolled off the assembly line.

One thing of concern was the GM warranty and I didn't want to do anything to void the factory warranty. So far the CAI and the QTP exhaust cutouts do not effect the warranty. I talked to the Service Manager @ the GM dealer where I purchased the car and he told me an engine TUNE WOULD likely void the GM warranty. I hope you researched the warranty issue with Ford before you got the tune. The service manager told me that if something happened to the engine on my Camaro and I restored all of the original computer parameters, a simple computer read would be able to tell that the settings had been changed.

I have also been interested in a super charger but I found the same thing you found, $6K+ is more than I want to spend right now. There is a great Camaro forum called Camaro5 that has been super helpful and one thing that has come up is when you increase the HP the "downstream" components may not be designed for this additional HP. Things like U-joints, drive shafts, clutch, etc. so it's not so simple just increasing HP, there is much more to consider.

You may want to check out the QTP exhaust cutouts and I would caution you to check mods that can void your Ford warranty.

Best of luck!

Russ

Welcome to gearhead utopia.

I've gone through so many cars and have just now been able to say that my name is The Good Life and I'm cured!

My son on the other hand...I purposely kept him away from my cars as I knew how addicting power adders can get. So what does he do, he buys an NSX and starts with the air box thing. Next came a carbon fiber air box. New 4.20 rear end and all new close ratio gears in the trans. Then the first of three COMPLETE suspension change overs. Two stainless steel header changes, three muffler changes and new wheels from Italy! So he gets bored with it and installs a new supercharger with a larger throttle body. Then a new carbon fiber wing to replace the factory item. Just last week, he takes out the stock power bucket seats and install racing bucket seats that were custom built and took a year to complete the mold and production.

And mind you, all of this passes California smog checks!

Good luck.

Is that an "oxygen" bottle? I already have one and put on the mask when pulled by the police to get out of a ticket (along with the AARP card!)!

I've got nitrous in my TIRES, but the not the "juice", yet.

Santa doesn't know I got the CAI and tune, yet! ;?

Good idea on the 3.55 - kind of a "happy medium". I think I'm running only about 2,100-2,200 @ 60mph (in overdrive) right now.

The labor $'s are a killer on the rear end change - about 5hrs. @ $89per!
