I know some dumb A$$ES who drive that fast on the interstate. 
Anyways, Ide say even with 4.10's he'de still be able to hit above 130mph.
Im planning on 4.30s in my auto. Ive thought about 4.56's but still inconclusive as to wether their too much gear for an 01 GT auto. |

this is just an educated guess, but IMHO theres no way in hell an auto is gonna get near those rpms/mph while staying n/a with bolt-ons running 4.30s. i say go for the 4.56s, w/o them, i dont think you wont get the rpms you need to run at maxx potential. worst case senerio, you swap to 27x9 Hoosier slicks instead of the standard 26x8.5 ET Drags..

Do you have 4.56 gears or 4.30's ?
EDIT: Whenever I do the gears, should I do a rear-end rebuild ? Like 31 or 33 spline differential and axles ? Ive been told I should. Im wondering if there is any advantage to this other than insurance against breakdown. I know I should weld my axle tubes and torque boxes up, but what else ? Thanks again.

with an auto you can get away with alot... they simply dont hit the rear like a stick does so you can save tons of cash. that said, if i had an auto this is what i would get...
4.56s
31spl axles
31spl Ford truck Trac-Lok
full bearing/seal kit
contact Randy Stinchcomb in the Parts Department on Mod Depot, he will hook you up.
im running 4.30s with a 5spd.

Thanks. I was wondering how my highway rpms would be. There not bad now but I really need gears to get going. This torque converter is great, just the stock 3.27's suck. Thanks again. |

3k is a bit high. I might just have to reduce my cruising speeds. Any idea on how that would affect my car in the long run ? Im going to have to drive a couple hundred miles just to reach a decent 1/4 mile track. |

Your top speed is going to be limited by power and aerodynamics. Not gearing. Its not possible to tach your stock gears without massive power and aftermarket aerodynamics. I believe a 5spd with stock 3.27 gears would tap out somewhere around 210mph, maybe a bit more. With 4.10 gears, this will drop to somewhere about 175-180mph. You most likely wont hit that speed either. Most GT's with stock rear end gears reach about 140mph before wind pressure pulls them back. With 4.10's, the pull is increased enough that you can actually go further and hit 150mph easier than you could hit 140mph before with the stock 3.27's. |

K&N Air Filter - Easy to install C&L 80mm MAS - Simple enough to swapout. They even include the tamper resistant torq bit. C&L TrueFlow Inlet Pipe - Looks great, helped with airflow. BBK 75mm Throttle Body - Not scary to install at all. Improved throttle response. Magnaflow catted X-pipe - Had some help with this one (4 hands are better than 2). The newer the car the easier to remove existing equipment. Magnaflow catback system - Also had help with this one. Installed at the same time as the X-pipe. Overall install time for exhaust system 1 1/2 hrs. PERFORMANCE OPINIONS - I'm pleased overall with all the mods. It had taken a few driveing cycles for the computer to compensate for the changes. However, everything pulled together. All changes in performance were expected except for the slight loss of torque on the low end of the gears. It does perform beautifully through the mid and upper ranges though. MPG (stock) was averaging @24, now with the mods it's averaging @23.8  Not bad!!! And with the Magnaflows it sounds great. What's Next? - 3:73 gears and a dyno tune  |

Got 4.10's in the 2000 Auto along w/ a 3000 stall, shift kit, and a tranny cooler.
IMHO, I think 4.30's would be AWESOME in a late model Auto. I just might do it before long :evil:

I really want to do 4.56's but Im afraid it will be a bit much. I know I want at least 4.30's for sure. If only I had a gear calculator for the 4r70w automatic.  |

Hello all, I'm new to the forum and saw this thread so I figured this would be a good place to intro into.
I have a 1996 Convertible GT Export or in Germany, a Cabrio Mustang GT. I'm not sure exactly what is different ( except all the export stickers on certain fuel and engine parts ) but they seem to run better stock than the stateside counterparts. This is how the scene went: German Politie, "Why are you going so fast?!" American servicemember, "Isn't this the autobahn?" GP, "This is a speed restricted area!!" Me, "ooops." Apparently I was doing 245kph through an 80kph zone or just about 152mph. Not good, especially when the guys on base recieve the citation to foward to my First Seargent ( but that's another story ). Anyway, I know of a 96 and 97 that have also done 150 and my friend Mike who did 164 in his 96 Cobra. I'm back in the states stationed in North Carolina now and keeping the speeds to a more rush hour friendly tempo. But here is how the mods go:
K&N Filter: Of course. You should have seen my German landlord freak when I started taking apart the intake on a then new car. Can't do that with Mercs and Bimmers or the company voids everything and maint, gets really expensive.
MAC Cold Air Intake: Into the fenderwell
B&M Ripper: Easy to install and it's worked great; positive feel; no complaints
Saleen Suspension: springs, struts, shocks, quads, front sway bar, offset rack bushings, and rear lower control arms ( recently upgraded to Saleen N2 ) excellent feel ( especialy on the bahn ) and straight foward install.
Kenny Brown Subframe w/seat reinforced crossbar: No more front to back twostep on quick turns. Chassis more solid on all road surfaces
Front Bullit Calipers: More pistons=better stopping
13" Power Slot Rotors and Braided Front Hoses: Learned a good lesson once, the faster you go, the faster you will need to stop. Upgrade those brakes!
FRPP Aluminum Driveshaft: Less rotating weight is always a good thing
FRPP 3:55 Gears: Quicker into the powerband than stock but not as gas consuming on the long drives. Been all over Europe and out to Cali. twice and still got 27-30mpg on the highway.
Flowmaster 3 Chambers: Nice sound and easy to install but am planning to put a Bassani X with a Borla Catback next year
Steeda Pullies and Timing Adjuster: Once again a quick and easy install; set to 14 degrees
Steeda Strut Tower Bar: A vert can never have enough in chassis stength
Weld Racing Wheels: 3 pc Magnums 18x8 front, 18x9.5 back
Michelin Pilots: 245x40x18 front, 275x35x18 back
Other Stuff but not really a mod: T/A Diff. cover, CDC light bar, Saleen Tonneau cover and S281 rear wing, Alpine deck and carbon fiber trim pieces.
Other noteables: I've also driven the Nurhenburgring ( The Ring ) where suspension is a must! Also brakes, MUST have BIGGER BRAKES, Alcon, SSB, Bremo, anything! I"ve been on the F-1 track in Spa Belgium as well. It's like diving through the country only at really coool speeds.
Gotta Go |

MAC CAI-Nice, good looking mod. I got the throttle body to fenderwell model, and was very pleased with the looks. I will probably go with the Steeda soon, though. MAC PULLIES-Decent, again I will probably upgrade to Steeda, so I can use their timing adjuster. Paid a shop to put them on...that was stupid. We put a set on my friends 91 5.0 and I felt like an idiot after seeing how easy it was. It was a 5.0, though... BBK THROTTLE BODY-I got the 70mm. This was my first mod. I didn't really feel any increase from it, but it had to do something. Got a lot of stickers with it... MAGNAFLOW CATBACK-Probably my best mod to date. Very happy with the sound and power increase. Nice and subtle while cruising but sounds really nice under acceleration. STEEDA Tri-AX- I love this shifter. Good, solid shifts and a very nice 2-3. My stock knob didn't really line up so I just got the Steeda knob too.
Overall, with my extremely extensive list of mods here, I didn't really notice too much increase on my car. Well, maybe a little. I dyno'd it a few weeks ago, and the results were greater than I anticipated. I was expecting MAYBE 200 RWHP, but the dyno showed 218. I was very pleased. |

I know i'm a little late chimming into this thread but i had to find a lot of time.
List in order of mods.
Flowmaster three chamber catback - gave me a little rumble with the stock h pipe. Wished I had gotten the two chambers.
Superchip - Wished I had waited til I had more mods, but thats what I get for listening to my friends. Gave me a little more power by the SOTP meter. Rev limits were gone and speed limiter was gone which is nice when racing.
Eibach Sportlines - The 4x4 look had to go. Lost some traction, but it was worth it for the looks. Handles nice around corners.
MAC Prochamber - Did this more for the sound, but actually gained a lot of power, think I lost a little torque, which I could have spared. Sounds amazing, but hits on everything, and it's definately not stainless.
Steeda MILS - got these with prochamber, a must.
Nitto 275/40/17s - Had to have these. Much more traction, and they look sic from the back with the 2" springs. Going to go with DRs in the back next set.
Steeda underdrive pulleys - Lots more paower and torque throughout the power band, definately one of the best mods.
BBK CAI - Um well thought it was good for my car to have the intake go to the fenderwell, but after having some problems with idling, and learning that the MAF doesn't like "sideways" air, going to go with one in the engine bay next.
Welded in @ chamer Flows - Welded these into the exsisting Flowmnaster catback setup. Got tired of being the quite stang on the block. Now it's finally loud as hell.
KIng Cobra Clutch - Nice feel, grabs harder, self explanitory
Steeda ajustable clutch kit - This kit includes cable, quadrant, and firewall adjuster, a must have for any aftermarket clutch. Nice to be able to adjust the clutch points.
Ford 3.73 gears - Got these kinda recently, and man I should have gotten this sooner. But I plan on going with the KB soon so I shyed away from the 4.10s, but if I was staying N/A i would have done 4.10s.
DiabloSport Predator - On order. Finally after waiting forever for this thing to come out. I can finally get rid of my crappy Superchip and "tune" myself. Will be here monday.
Also on order - 10th Anniversary Cobra wheels, can't wait to get these on the ride. Wondering if I could fit a 315 DR on them? Anybody know?
Hope these things helped some people out. I'm also getting the Steeda full length subs, and LCAs soon, along with a Pro 5.0 shifter.

| | Steeda Tri-Ax - Do I need to say how nice this baby is once more? BBK LT Headers - Very nice quality. I dropped the K-member. EGR tube; however, did not fit quite well. BBK Shorty X-pipe - Perfectly matches the BBK LT. looks great! Magnapack Cat-back - speechless |

| | | 1999 Cobravert
Bassani X-Pipe, K&N Filter, 3.73:1 rear,
Cobra R wheels with 275/35/18 Bridgestone Potenza SO-3's,
Kenny Brown Signature Series Full Matrix Suspension,
Steeda Triax, Diablo chip. Rear Seat delete,
Piper Motorsports Custom Roll bar, Schroth Harness,
The KB suspension with Bilsteins, sport springs, IRS torque brace, IRS rear steer kit, camber/caster plates, strut tower brace, k-member brace, jacking rails, full length subs, matrix braces in between, etc. has been an amazing difference. Not cheap but well worth it.
Diablo made a little difference. but not much.
love the 3.73 as the 4.10 I tried was too short for road use.
Bassani was a good boost and sounds nice.
dynoed at 300 rwhp 315 ft/lbs torque |

ill chime in.
dr gas off road X - pricey but well worth it. sounds amazing, ive had so many compliments. good sotp increase.
2 chamber flomasters - welded in, sounds great combined with the dr gas x, my favorite sound ever from a car except for a kb cobra. a lot of people will say to not use a x pipe with a chambered muffler but i love it. not raspy and pop corn sounding either.
frpp 3.73s - feels much stronger though i wish i had gotten 4.10s.
thats it for now, im broke. |

K&N FIPK - seemed to increase throttle response a little. Sounds nice Steeda Triax Shifter - can't say enough about this shifter. What a huge difference from stock. Magnaflow Magnapacks - I love these things. True muscle car sound.
__________________________________________________ ____________
Two more and I'm done...
1. Magnaflow catted X-pipe - to finish the exhaust.
2. Eibach Pro-Kit w/ some Bilsteins - improve the handling. |

Fully agree
My 4.10's actually help me avoid tickets on the highway and interstate, b/c it is alot easier to cruise at decent speeds IMO.......and i don't like cruising at 3,000 all the time 
But, I got 2 new additions for the thread.....
I installed a Walbro 255 in my car, and I'd advise anyone who is looking into a fuel pump to get a Chicane style (Focus, Cobra, etc..) I just had toooo many problems w/ the Walbro.....it just sits around while my stocker gets me everywhere now.
Also, I installed a TFS Upper Intake Plenum. Install was easy enough, and it looks great. There is a lil SOTP gains, and the Plenums have been shown to give a solid 5-10 RWHP and Tq. gains.
