Stock for stock, Mach 1 vs LS1 fbod is a drivers race...period.

 

Manual Mach1.

From production stats (mostly magazines who tested the cars):

Mach1- 13.2 1/4mi
T/A -13.4 1/4mi

So it's really close, but a driver's race. The Mach should win.

 

Yea, there is a lot of misinformation in this thread. Such as there are A LOT of bone stock mach's in the 12's. That's news to me, I've heard of one and have seen zero. Also a mach pulls nothing like a cobra. If you think it does you've never driven a cobra, and yes both have the 32 valve, but the internals are different, as in not the same engine.

 

Then there are a lot of freak ls1 cars out there. **** on mag times.

 

Did a little research, found some races, not quite stock for stock but here it is:

Here's a race where both cars just have exhaust, seems to be the closest one:

As you can see, the live rear axle causes a much better leap off the line by the Mach1 but the LS1 pulls it in to a close race down the stretch. A

Anyway, hope these videos helped.

 

Never said it pulls with a Cobra, just said that it's not that far off.

By the way, to back that up. Just to clarify though, looks like the Cobra missed a gear the first time, which would explain losing as he shouldn't under any circumstance:

Due to the mach's more aggressive gearing it might "feel" like it pulls just as hard, but I can assure you, the Cobra has more nuts down low and up top. Just as if you've ever driven an lt1, it might feel that it has the pull of an ls1, but the ls1 has the definite power advantage. The truth is in the numbers.

 

Oh I know, check out the video I added to the post above. I know the Cobra has more kick, but the Mach doesn't trap much lower, not sure of figures, but it's not bad for a car with 85hp less by Ford's rating. By the way, correct me if I'm wrong but don't both the Cobra and Mach1 use 3.55s?

 

A Mach 1 with a shifter is not faster than a C5.

 

from what i've seen at my local track,stock Mach 1s go around mid 13s with a good launch.that's not to say they can't go a little quicker,but i've never seen one anywhere near the 12s.(bone stock) the vette should take him.

 

Mach 1, as stated before is usually a drivers race vs an F-body.

I've never seen a stock Mach1 in the 12s in the 1/4. Most of the videos posted previously show a modded mach with someone that can drive, against people that are near stock, and basicly sleep at the wheel.

 

Yep, they both use a 3.55 gear, but the transmission gearing in the 5 speed mach is steeper than the gearing in the cobra. I'm not sure of the exact gear ratios off the top of my head, but 1st and 2nd gear is definitely more aggressive.

 

Oh durrr. I forgot basics, 6spd Cobra, 5spd Mach1

 

What's all of the hype about the live axle making it get a jump off of the line better than an LS1? F-bodies have live rear axle's too...

I also have to agree that many of those videos had the fbody sleeping off the line, or the two where the Mach had the camera guy in the passenger seat. He let off in both videos right after he shifted and right before the LS1 shifted.

 

 

Right f-bodies do but vettes dont, they have IRS.

 

Yessir I agree, but he sounded like he was comparing to the F-body when he said "but then the LS1 pulls" after showing several F-body vs. Mach races.

 

Agreed - I've never seen such a collection of bad drivers. Definitely adds creedence to the words "drivers race". Both the firebirds in those videos were two cars off at the start.
Hell, the GT in this video http://videos.streetfire.net/search/...3cc1ae130d.htm walked out three cars on that guy, with two passengers (I'm guessing a well modded example of a GT, as they are mid 14 cars around here)

IIRC, Mach 1's with the 5 speed have a 3.35 first gear, and Cobra's have a 2.66 first gear, similar to the F-body.

My buddy has an '03 Mach with full exhaust, and I've never been able to get him to even play with my SS. But I bet it'd be a close race.

 

the fastest mach1 i have seen around here is running 4:10 gears and a 150 shot, full bolt ons, he runs dead even with my friends '01 Z06 cam and headers 404/385 wheel.
