When i get my tax refund back im gonna have to give Mike a call and order me some parts... i was just curious, i have a 2004 regular cab 4.6 and was wondering roughly what kind of rear wheel horsepower will i receive from getting the magnaflow "lightning" exhaust, af1 intake, 9300 93 max perf tuning and dual electric fans? and does taking the fan off void the warranty?

thanx in advance

Hi Timp,

As long as you replace the factory fan with something that is going to provide adequate cooling for your engine, then no, removing the factory fan isn't going to void the warranty.

It's hard to say exactly what your rear wheel horsepower will end up at, as even in stock trim they vary and the new body style trucks with automatics tend to have a bit higher overall driveline losses as compared to the 2003 & earlier trucks. And of course, dynos themselves vary rather widely - one dyno may read 20 Hp more or less from another unit. From all of those mods combined on a new-body style 2004 4.6 F-150, figure that with a good dyno & proper controlled test procedures you should see an increase of something along the lines of at least 30-35 HP more at the rear wheels, and may well be more - it could potentially be easily 40+ HP - but I prefer to be conservative & not get too hung up on one set dyno number, we have to deal with reality - and the reality is these vehicles can vary significantly, both in their stock power and in terms of their exact response to a given type of modification.

One such factor causing variances is the exhaust - how well the cats & Y-pipe flows varies from truck to truck, which will effect power gains from the exhaust mod, for example - one truck might see 14 HP where another sees 8. Fuel quality will also make a difference, even of the exact same octane - some 4.6 trucks we tune are running on 93 octane fuels good enough to support as much as 6-8 more HP (normally aspirated) than with another lower quality 93 octane fuel - it happens. Computer code can make a difference as well - some have "worse" tuning from the factory than others - the 2005 5.4 F-150's with a code of TEM4 are an excellent example, as that's a terrible code stock - runs too lean for good power at heavy throttle & has terrible open loop delays, etc. So they gain more from our custom tuning than say, an identical truck with a code of EAY4 or a TEM6, for example. You get the idea - and this is something that not many companies talk about, far too many will quote one number and present it as some kind of "absolute" - and so they in effect train the consumer to look for the biggest HP gain claim anyone makes, rather than taking their time, doing their research and working with a company that is truly expert & specializes in the vehicle platform *you* own.

One very nice aspect is that the actual amount of improvement in acceleration (1/4 mile times) from our tuning is always more than what the raw HP gains would indicate mathematically on paper, thanks to numerous things we can do in the PCM program that improve acceleration times in addition to what the raw power gains do.

Some vehicles like yours (new body style 4.6 2V F-150 automatic) will show as much as 160+ HP at the wheels stock on a good eddy-current dyno, while another truck may show only 135-140 HP at the wheels on the same dyno & same day. In the new 300 HP 5.4 3V automatics, some will show well over 220 HP at the wheels stock, while others show as little as 190. The trucks vary just as dynos & fuel quality can vary, & we have to deal with reality. So what you end up with will vary as well - the best you can do is to use modifications that do the best job in each area.

For another example - there are some 1999-2003 F-150's configured with the 260 HP 5.4 2V & automatic transmission, 2WD, short cab short bed that with just our Stage 1 setup (tuning, intake & exhaust) and good traction will run as quick as mid-to-high 14 second 1/4 mile times! And then other F-150's of that exact same configuration & mods will run "only" a 15.5 on the same track at the same time, for example.

Just trying to give you some rough ideas as to the range of power gains from those mods as well as amount of potential variances in these vehicles, basically. The bottom line is use the best parts & fuel and you'll get the best results on each vehicle, no matter what else. Feel free to give us a call to go over this in more detail, if you like - we're happy to help.

Good luck with Uncle Sam this year & talk to you soon!

 

Thanx Mike

I really appreciate the info, i guess ill just have to try em out and see what happens... there are chevy and dodge punks riding around town "testing" me so i wanna add a lil spruce to my truck so maybe i can embarass em! ford doesnt get much respect around this way for some reason... im gonna try to change some minds!

 

u said i would get better quarter mile times than what the hp gains would indicate... thats mostly what im getting the mods for anyway is better quarter mile or 8th mile times! so thanx for that lil bit of extra info, i guess in a way thats what i was really asking in the first place but i guess i was just trying to relate hp to better times! thats my bad!

 

Hi Timp,

You're very welcome!

It might sound like blasphemy, but I have to confess that I like almost any cool vehicle (except the "fart" cars - you know, the obvious ricers with nothing other than a coffee-can muffler & big wing on the back). I don't care if it's a Ford (my favorite, obviously) or a GM, if it's a cool vehicle that the owner has put some good hard work into, then I like them.

However, that being said - there's *nothing* like a fast Ford, and few things more enjoyable than showing a GM or Mopar truck our tailgates!

We can easily get your vehicle performing very well for you, and turning significantly quicker 0-60, 1/8 & 1/4 mile times, as well as much higher top speeds, too.

So hang in there - have fun & we'll talk to you soon!
