RE: GTvs mach1
Anyone that knows anything about engines know that Hp doesnt matter untill 5000 or so rpms
I know it can be said about ANY car, but there are always the less than superb drivers out there. I have a 99GT 4.10's DR's o/r H and catback and ran a lousy 13.9 when I'm capable of a 13.5 with a better launch, at the same time there was a partial exhaust only Mach 1 running the same 13.9's at a 105 or 106 trap.
From everything I have read, and seen debated, Mach 1's are usually good for mid 13's with the average to good driver. However if driven correctly are good for 13.3's or so.
If yorue just looking to run with them from a dig, then 4.10's, DR's, midpipe, catback, and a good driver mod should be enough.
Once the Mach adds gears and DR's, you might need F/I

You will have him in the dig stock (from a start) 4v's suck at torque but they are amazing at high rpms. You need headers, x pipe, exhaust, 75 mm tb & ui, pullies, tuner, CAI, and you dont have to have gears. I could run with the best of um before i did my 4.10's. They pull alot harder up around 100 mph though becuase they can breathe a lot better. A mach one is your car but with 2 more valves. Think about it. There is nothing you can do to make up for that up high in the rpms.

HAHAHAHA, you crack me up man. Four valves suck at torque? LMAO.

RE: GTvs mach1
To answer one of the questions asked, the King Cobra clutch is much stiffer than the stock on and the disenguage distance on the pedal is shorter. Its a nice clutch, would replace my clutch with it again and again if i had to.
The Machs here in Orlando must have pretty sucky drivers cause at the track i never see anything lower than a 13.4 and i see many bolt gt's hitting 13.0. Given that there are more gts and mach in general yes but bottom line i hit 13.8 with no lt's, sucky tires, nasty exaust leak,on a stock tune.
Full bolt ons will easily whoop up a mach, given your a good driver.
Forgive me if your a Mach driver and have hit less than 13.4, personally i just haven't seen it

RE: GTvs mach1
a guy i know has a mach one and i got a 04 gt stock, we went out for a couple of runs on the highway and i got killed when we would go from 60 and 70, he would walk away pretty hard. Now when we went from a 30 roll it was pretty close, but they just have too much revs on the gts and when we are shiftin theyre getting into the power.

RE: GTvs mach1
Matt. Matt. Matt. Physics 101 man. Take it. You cant build good torque with a lot of air intake at the low end. Why do you think that you loose a little torque on the low end when you switch to cat back and off road x pipe and you really feel it with LT headers. The 4v has a lot of intake to help it breathe but, also, like putting a 75 mm on your mustang, its great op end but not great low end. Its engine physics man. More air doesnt always equal more power. Atleast on the low end. You have to have an amount of restriction and back pressure. Thats why a 1000 cfm 4 barrell carb sitting on a superhigh rise intake is such crap for torque. Thats why 4-barrell carbs only open up 2 barrells at first and then 2 more at high rpms. Its racing science my friend.

RE: GTvs mach1
theres a guy i know that has a 5spd mach w/ 4.10s we raced 6 times and i beat him 3 times by about 3/4ths of a carlenght and he beat me by about a fender.my mods are: k&n filter, tb&plen, UDPs, LTs,h pipe, stingers & 3.73s. from my experience it should be a drivers race betwen a lightly modded GT and a stock mach

RE: GTvs mach1
I agree, GT with the right mods and the right driver can beat a Mach, but overall performance goes to the Mach in my opinion. Revs are highly under-rated. Put those same mods on the Mach and you have a killing machine, add an s/c, well you know what happens!

03Mach 1 dyno sheet
04 Mustang GT
They both peak at around 4200 rpms. As you can see at 2k rpms the Mach still makes more torque. At 3500 rpms the GT is basically through, while the mach moves up to peak 30 ftlbs later.
How the 2v has more torque is beyond me. The cars have basically the same mods. Midpipe and catback. Your argument isnt valid...

RE: GTvs mach1
From personal experience I can say that Machs don't have very good low end torque. I have a hard time getting off the line and lose to GTs all the time in short drags. But, give me some running room or race me from a roll and I own.
Although, I have had the opportunity to test drive a GT vert and it had awful low end torque. Maybe the coupes do better since it's less weight.
Now, the new 3v Gt's...those suckers are hard to catch up with. Seem to have really good low end torque but I'm usually able to pull just slightly harder and can catch up to them with a little distance. But that's getting off topic...hey, who said anything about the 3v?
