If you're planning on gearing it, then go with a chip for the timing, it'll also correct your speedo. So get the gears done before having the chip burned.. either that or you can just have them include the gearing changes, and then your speedo will be a little off until you gear it for real.

And the exhaust does add hp.. it's dyno proven, especially when there are other mods... having a better than stock exhaust brings out more potential power from the other mods :)

It all adds up.. lots of little small things complimenting eachother in the end :)

And these guys are gonna tell you not to waste time on 3.73 gears, go straight to 4.10's (I dont agree because I am not gearing mine... lol)

As far as headers go... the long tubes are the only choice, shorties arent worth buying, for power adders anyhow. They have nothing over stock manifolds. So, yes.. long tubes are worth the money.

Personally I dont think pollies are a good idea... It's just a matter of personal opinion though. I'd rather keep my accessaries spinning at the correct speeds. AND if you ever supercharge it you'll have to remove the ud pollies.

Supercharger might be in my future, so thats another reason I decided against it.

You said that your gonna get the 75mm TB, but you didnt mention a Plenum... I would get the C&L Plenum, and the BBK or Accufab TB... best combos, per modulardepots plenum showdown results, and all the input here from the racing guys :)

Also... are you sure you want to time it, with gas prices like this??? You'll have to run 92+ octane, you know that right?
so that is an ongoing charge everytime you fill up the tank... I just dont know if that gain in hp is worth it.

but then again.. I dont know the details of how much you are gonna time it, and I dont dont how much you'll gain from that.

Oh yeah... and that densecharger pipe I told you about... well C&L makes one too, I dont know which is better, but they're cheap and both are better flowing than the stock one.

depending on how much timing you're planning on giving it.. my guess is you'll be around 250 - 260rwhp

same as me... with out the timing! :)

(this is funny, I feel like I am standing at a party listening to a conversation. Then, at this point is where I butt in).

Hey, just a point of clarification. If you want gears AND to advance your timing to run high octane, but are concerned about fuel prices then go with a chip or a programmer. The programmer will allow you to make changes whenever you want. If you get the right chip, you can have multiple programs. I have three settings for my chip. There is a toggle switch that I mounted by my cigarette lighter:

1 - Totally stock!

2 - Programmed for my mods, timing is advanced, and speedo is adjusted for gears.

3 - Same as #2, but timing is not advanced. Can run 87 Octane.

If I ever need to make changes, I can send it back and have it reburned. (for a fee, of course).

I went with 3.73 mostly because I plan on adding nitrous in a few months.

Lizard King - good to see you back around here. I remember you from when you had the green car ripping off stock 1/4 times that nobody could believe. I was coming off owning a 5.0 Mustang and had just bought my 1st '97 T-bird 4.6L and was new to the whole modular game, so I trolled around the modular forum more than anything, never really posting. But needless to say, I remember that car and your driving skills being talked about all over the web.

The pulleys are going to give you power, period. Not 13rwhp like the old 5.0's, basically because ford is getting more agressive with their own pulley specs, but power non-the less. So for the price, they are a great bang for the buck. You won't have any charging problems or anything. Worst case senario, driving at night time in the rain with the stereo and A/C blasting, you might bog down the alt at idle, but thats about it.
I personally agree with the other guys and would let the timing be controlled with a chip or tune. Right now I think the best game in town is SuperChips Custom Tuning. This isn't the plain Superchips thats still around, this is 100% better. Either hook up with them for a dyno tune, or check out their stuff HERE.
As stated, Long tubes are really the only option as far as headers go. Now whether or not they are worth it depends on what you want out of your car. Thats up to you.
The 75mm TB should be matched with an aftermarket upper plenum.

For what it's woth, I wish I had gone with a custom programmer. I got cheap. Superchips makes the best based on my research and Diablo has one for the cobra only. But supposed to have one soon for the rest of us.

I've ran at multiple tracks in my vert. On everything from street tires to slicks, w/ only a helmet.

My car is a consistent 13 second car also, and a vert to boot....

Never been asked to tech, or leave.

Stock, I ran a 14.5

-Will

TARZAN... will you please post all the mods you've done??

A 13 second car is awesome! And posting the specs will help us who are just starting out with the mods :)

Thanks!

I ran 14.1 stock in my vert, and now it's running 13.5s@101-102

GTvert... whats mods have you done? to be running 13.5's :)

So far I have :

Hypertech Power programmer
Steeda Underdrives
4.10s
bbk o/r xpipe
magnaflow catback
full syntehetics(reaching, I know)
pro 5.0
some cheap Cai I got off ebay for like $40

that's all for now, I have a two wheels like yours that I bought to put some drag radials on, but I'm hoping to get them for my birthday in a couple of weeks so I have to wait I guess.I'm also getting ready to put a new plenum and tb on. Have you gotten to the track yet? Practice is the most important part of good 1/4 mile times.:D

I noticed you have the same interior that I have, did you consider white face gauges?I can take a pic and post it if you want.I know it's not going to hepl performance, but is does break up the interior a little bit.

Whats the "pro 5.0" ??

And yeah that would be great to see your gauges :)
The dash is kinda boring huh? lol

Thanks man

it is one of the best short throw shifter you can get

Oh ok.

The only shift I have trouble with is 4th to 5th... its a stretch!!

So the short throw shifter makes that an easier shift??

it makes it easier to shift fast and is safer on your trans due to stop bolts to it makes it less prone to breaking shift forks in the trans

Awesome! Sounds like its needed :)

So how hard is the install? Is it done from inside the car?

AND can I use my stock boot and shift knob????
Dont laugh, I know everyone gets rid of them, but I have some kind of attachment to mine! lol

Gotta love the leather wrapped shifty :)

its very easy to install its only 8 bolts
4 for the dust/noise cover and for the hold the shifter to the trans

and yes it is done from in the car and yes you can reuse the boot and shifter

I got in on this late but I ran 1 mph faster consistantly with the air silencer in.

And this was on an 01 cobra. If it isnt choking a cobra it sure isnt choking a GT.

This is just my opinion backed up by 20+ 1/4 mile runs.

that is true for poeple that run with there headlight in

in you take out the headlight you can pick up some

i ran faster with mine out then with in even stock
so like everyother mod some cars respond better then others

I've proven that one with 200+ runs on 2 different GTs /each.

Headlight out works.

Agreed, w/ an open element filter (that being an aftermarket MAF, K&N FIPK, Steeda CAI, etc...) the headlight out does help. I have proved it MANY times. I've gained as much as a full tenth depending on weather.

Well, here we go, a mod list......

I ran a 13.5 w/ lil traction w/ these mods:

FRPP Headers
Magnaflow O/R X
Flowmaster 1 chamber dumps
4.10's
3000 Stall
Custom Shift Kit
Tranny cooler (doesn't improve ET's, but improves tranny life ;) )
X2C U/L C/A's
removed front sway bar
Steeda U/D Pulleys
C&L 80mm MAF
FIPK Airtube
BBK 75mm TB
TFS Plenum
JMS Chip
weight reduction
26X10 ET Drags
15X8 Prostars out back...

I coulda actually got a couple more tenths outta it, but the tires were WORN out. I was actually spinning a bit outta the hole, cut a 1.9 at best. shoulda got closer to a 13.2-3 IMO.....

now I've got some 4.30's, a new superchip, plan on getting some aftermarket subframe connectors, and have some new Control Arm bushings to be installed.

Also have a bud who is gonna custom tune my chip, and will be getting some BFG DR's....

Should be in 12's or DAMN close:D
