Question Rear Wheel HP question...

I've decided to go with the FRPP and the Ford X-pipe.

The Ford website claims that the FRPP will give me a 20HP gain at the wheels. Doesn't a stock Mustang have like 256 RWHP? Does that mean I should be getting 276 RWHP after the FRPP is installed and then another 5 HP with the Ford X-pipe= 281 RWHP?

thanks for your help...

you would probly get better numbers with a intake and tuner from Bamachips and a pypes off-road X from Brenspeed unless you want to keep your cats then get the ford X, then get some Borlas or Coffins, the reason i say this is because even though they are ford parts your dealer will hassle you later and with a bamachips tuner you can always get upgraded tunes later on

I hope the dealer won't hassle me later. He told me that if I had the Ford Racing Parts installed at the time of purchase that it would not void my factory 3 year bumper-to bumper and 5 year 60,000 mile powertrain warranty. My car is being built this week and is due to arrive in late January. I need to make a decision about this soon.

I really love the Ford's GTA exhaust and prefer to keep my cats on. I know I'm stealing someone else's line here, but "if it's good enough for Shelby, it's good enough for me."

But seriously ...do you think that Ford Racing's claim of getting 20 RWHP is inaccurate?

How much more RWHP would I get with the Bamachipset and intake vs. Ford's intake (which I believe is the same as Steeda) and the Ford Racing 93 octane adjustment made with their Pro-Cal tool?

i am going to say right now that the pro-cal is programed for those mods only and can not be changed later it is a good deal but ford also sells the Drag Pack for the car which has, gears, intake, shifter if standard, oil filter, headers and axle-backs...if they will garentee your warrenty then it is a good buy but you will get the mod bug later, and Doug's (Bamachips) tune and 93 Race tune you are looking at atleast 25+ RWHP with just an intake and tune

oh and the ford X is good but you can also get a muffler shop to do it custom for you and still keep the cats, either way ford even says you need to cut out your old H, and more then likley you will get about 22rwhp out of the ford kit with the X

thanks Reddragon777,

I hear ya....I already got the "mod bug" and I don't even have the car yet!

I took a good look at the drag pack, but I do a lot of freeway driving and I wanted to keep the 3.55 gears for gas milage sake. The other thing is that the drag pack doesn't come with those lovely GTA mufflers. I do like the shorty headers option though. Where can I find Doug's Bamachipset anyway? Can I still get the chipset after I do the FRPP install?

yeah you can just order the tuner from him www.bamachips.com and if you want there is a member here, KC he is a manager at a ford in california and gives TMS members a 15% discount on ford parts and can get some of the really hard to get items like the GTA exhuast, another thing is that the new 05+ stangs needs a retune for almost EVERY mod you add that deals with the motor, like underdrive pullies, headers, cold air intake so an SCT tuner from Bamachips will help

You may still want to consider a modified version of the FRPP Drag Pack. I'm guessing that your car is going to be a stick, based on your saying about wanting to keep the 3.55 gears. I put a modified version of the FRPP Drag Pack in my '05 automatic. I went with the C&L street CAI and the SCT tuner in place of the FRPP CAI and tuner. Then, I went with the FRPP ceramic coated shorty headers, the FRPP X-pipe, the FRPP/Borla alxe back exhaust, and the FRPP 3.73 gears recommended for the automatic cars. I'm currently running with an 89 octane tune from my local FRPP dealer (CJ Pony Parts). I haven't had my combo dynoed yet, but the CJ's staff estimates that I'm getting about 300 rwhp. This should translate into about an addtional 35 rwhp over stock (25 hp for the CAI/tune combo, 5 hp for the headers, 5 hp for the X-pipe, and 0 hp but good vibes from the FRPP/Borlas).

If you want just a little more acceleration without a major sacrifice in fuel economy, you may want to consider the 3.73 gears. My automatic '05 (which originally had the 3.31 gears) averages in the 19 to 20 mpg range in stop-and-go driving, and gets up to 27 mpg in highway driving.

Just some stuff to consider.

For those of you who are concerned about Ford factory warranties ???Once again ? it has to be proven that the aftermarket parts or re-flash was directly responsible for causing damage to the warranted part or parts in question and btw !!! no dealership has the legal authority to void any Ford factory warranty ? if a claim is submitted ? Ford's policy is as follows..step 1 the dealership's service manager is required to have a Ford feild service engineer brought in to conduct a full investigation..Step 2 if the feild service engineer is able to prove within a reasonable doubt that an aftermarket part or computer re-flash was directly responsible for causing the warranted part in question to fail ?? the results of that investigation are then submitted to Ford corporate headquarters in Detroit..Step 3 Ford corporate reviews the feild service engineer's results..Step 4 Once a decision has been reached ? Ford then submits it's final decision to the dealership's service manager either approving the warranty claim or denying it...Therefore if any dealership claims they can void a Ford factory warranty for any reason and especially for just installing an aftermarket part ?? their completely full of and if your curious as to how I found about this ?? upon doing some extensive research, I spoke with 2 of Ford's feild service engineers who both confirmed Ford's warranty policy...So there you have it in a nutshell..

If your really interested in the Ford racing cold air intake ?? the intake itself is made by Steeda..if you go to www.brenspeed.com ? you can get the Steeda intake and SCT tuner combo for $675.00 and you won't find a better deal than that..

~Tifo
Again your much better off with the SCT tuner over the Ford racing pro cal tool ? the pro cal tool is nothing more than a very conservative tune which is only good for the cold air intake and the MAF calibration..other than that ? you won't notice much of any power gains and if you should decide down the road that you want to add other modifications ? you won't be able to make any adjustments or changes and Ford's claim of 20 RWHP is definitely not accurate at all..However you are correct about the Ford racing intake being the same as Steeda's ? in fact Steeda actually designs the Ford intake and is a direct partner with Ford in their technology transfer program..

Thanks for your comments guys...

There are some pretty good suggestions here. I am interested in the 3.73 gear ratio, but I'm not experienced in tuning at all and that SCT thing scares me. I looked on the website and saw that you can adjust your spark plugs, idle and all kinds of stuff I don't even understand. What happened to just bolting on the parts and VROOM!!!!

I think I need to take a course on how to work that Xcal2 SCT Bamachips thingamajig. Anything with the word "Bam" in it has got to be worth buying!

BTW, how would I re-program the speedometer to know how fast I'm going with the 3.73 gears anyway?

I think you'll be happy with the 3.73 gears. They are a real good compromise for good acceleration and still-decent gas mileage.

The SCT tuner has all kinds of parameters that can be changed, including recalibrating the speedometer for gear changes, tire changes, etc. Also, the SCT tuner, being programmable, can be set up with either so-called "canned" tunes or (preferably) with a tune custom-tailored to your application. Good tuners like Bamachips custom-tailor tunes for you. If you don't want to mess around with it yourself, try to find a reputable shop in your area that regularly does tunes with the SCT tuner. That was the route I went. I've got the stock tune and tunes for 87, 89, and 93 octane. I have found that my pony runs almost as good on the street with the 89 octane tune as it did with the 93 octane tune. No noticeable difference, except for the savings at the pump.

if you get a tune from lets say bamachips you will not have to mess with anything, just plug it in, choose the tune you want, follow the steps on the screen and there you go, no needing to mess with anything

If I do the tune can I choose to put the car back to stock later for smog?

What if I disconnect the battery for some reason...will the car go back to default (stock) and I have to do the tune again?

The answer to your first question is yes..you can always return your vehicle back to stock, you just chose the return to stock option in the programmer and follow the on screen instructions...As for your second question ? No disconnecting the battery has nothing to do with changing any of your tunes, again the only way to return your vehicle back to stock ? is through your programmer(tuner)

If the numbers are important to you, I would get before and after numbers. From what I have read, all of these cars are different coming out of the plant and a lot of the dynos are running a little different also. If you do a before and after at the same place, you will know your gains.
