to all you ls1 owners i have a couple questions. my friend just bought a 2003 mustand mach 1 m5. it has 12k miles and he thinks it will outgun my buddies 99 a4 ws6. my buddy with the ws6 has a borla catback and y pipe and thats it. the stang is bone stock. my first question would be if they were to take their cars to the track, what do u think they would run in the 1/4? im sayin if both cars were driven perfect on a good track day? and if the stang would really outgun the ram air ta in a long run past 100mph or even keep up good?

im tryin to not have my my friends dragrace on the st. but the track when it gets warmer out any replies would be appreciated thanks!

 

The WS6 should have No problem beating that car . Only thing it has going against it is that it is an A4 and the stock gears suck in the quarter mile .

Not to mention the Ws6 is pushing WAY more power and weighs about the same .
Id say it should win bye 4 tenths at least .

I have seen stock auto's run 13.4's " LS1" as Long as the Guy in the mach1 dont use Drag radials . 60 foot times are everything in drag racing .
If it where auto VS auto or stick VS stick the LS1 would have no problem prevailing .
Mach1's are pretty quick though .
If he can get off the line way quicker he is probably gonna win .

 

That Mach I is geared better than your friend's Trans Am and probably makes about 320HP. It has 3.55s and at the most your friend has 3.23s. If he has 2.73s, the Mach I will easily get out of the hole faster and your friend will probably not pass him within 1/4 mile.

Tell your friend to put his foot on the brake, bring the revs up to 1,000-1,100, as soon as the light on the tree flashes yellow, quickly let off the brake and ease into the gas without trying to spin and then floor it. Tell him to turn his TCS off too if he has it.

 

The Mach1 is not making 320 HP .
ALthough I agree that it is geared for the quarter but the WS6 has the HP advantage over the Mach .

But the Mach is geared to get out of the whole better but LS1's gain speed quickly .
As long as the sixties are withing a tenth or to of eachother the WS6 should win . But I think it all has to do with th sixties .
If it was a six speed the results would be unquestionable .
Over the summer the Average Mach1 manual was running high 13's on average . I seen one on drag radials run a 13.3 .

 

1st, its a WS6 so it'll have 3.23s.
2nd, autos are easier to get the jump w/out spinning. Its difficult to cut a good time with a manual on street tires and the more gear you have the worse it gets.
3rd, Machs DO NOT make 320 whp stock. They dyno in the high 270 low 280 range. Stock LS1's generally start in the 290s whp and go up from there.

Only chances the Mach has is if the guy can drive it very well and the other guy can't or he has a dog of an LS1 that can only get in the high 13's. From a roll, it would be a close race though.

 

Have see quite a few 13.1-2's@105-107 for a stock mach 1...It can beat some stock LS1 a4 in the quarters...as for the 6spds they generally trap a few mph more...All cars run differently so its hard to match up cars on paper...that being said...w/ a good driver in each car stock for stock its a close race.

 

I have no clue what this guys talkin about....1.Its not difficult to get a good time on street tires ya just need know how to drive. 2. Ive seen 5spd mach's dyno as high as in the 290's bone stock so at 320 hp there a tad underated. 3. I assume you meant 270 low 280's...4. Stock LS1's dyno anywhere from the 280-310 rwhp(maybe more) 5. 5spd Mach'1 can beat a a4 LS1 heads up w/ 2 good drivers and is still a good race for a 6spd.

 

I have never ever seen a stock Mach1 trap that high.....ever . I have never seen one run that fast either and I have seen Quite a few run last summer .

I seen traps between 100-102 .

Some do run beter then others though .
LS1's are faster cars on average .

 

When My LS1 was stock I would have destroyed a mach 1 .
I easily ran low 13's on street tires with no traction .
Not trying to get ya worked up but from what I have seen with equal drivers stickVS stick or auto VS atuop the LS1 ..if its in good running condition should win everytime . it is a faster car , period . Im not trying to be biased im basing it on the numbers I have heard and from what I have seen .

Im sure there are some Manual mach's that can give an Auto LS1 hell at the track though.

 

Two words. Driver's race

 

And you forget something about the Mach 1's... NO torque.. Why do you think they come with 3.55's?

Also, the Mach 1's on a GOOD DAY will dyno mid 280's


They're rated at 300HP, and that's a pretty accurate rating.

The T/A should walk it unless he breaks something

Also, the Mach 1's run low 14's/high 13's in the 1/4, so as I said, unless the T/A breaks or just plain can't drive, he'll walk the rustang.

 

I've seen plenty of bone stock Mach 1's run mid 13s all day long here

 

So '03-'04 Cobras come with 3.55s because they have no torque?

The Mach's motor has different cams that are designed to make torque. You all forgot to say how much torque they lay down on the dyno, which is right around 300-305.

That's an accurate rating if the Mach has a super efficient transmission, which it doesn't. Most '01 Cobras dyno around 270-275, and guess what their advertised HP is? 320.

What do you consider walking? I consider walking when the car runs a full second slower than me, not a few tenths.

I love my F-Bodies, but it's a driver's race between the two cars, take your blinders off.

 

2-3 tenths is a walk but could still be a loss if one driver is better then the other.. 4 tenths is a really good walk . 5 and up is a huge walk away .
It takes quite a bit of HP to really gain 2 tenths on average for a car . Some cars only see 2 tenths from a cam and header install .
It dont seem like much but really it is . 2 tenths is bigger then you think . A full second is just simply an *** whoopin .

 

The '01 cobra engine and the '03 Mach engine are different. The Cobra was rated for 320HP and the Mach was rated at 310. And coming froma former Mustang owner, even with the 'different cams' to make torque, guess what? They still don't. At least not like the LS1.

Don't get me wrong, I loved my 'stangs, but they don't hold a candle to the LS1's

And the 03-04 cobras come with 3.55's because they are the Ford version of the Vette... Pure performance..

And MM&FF, with a GOOD driver, could only manage a 13.47 on the Mach 1.

I don't think that your average joe could match that time.

But anyway, I digress.... The DOHC 4.6 is a great motor, noone can deny that, but it REALLY needs GEARS!!

You guys think that the LS1 benefits from deeper gears? The 'stangs can easily gain .2-.4 in the 1/4 from them!

Anyway, I'll be quiet now.

My final word is that the T/A shouldn't have any problem with the Mach 1, unless the Mach 1 guy is a professional driver.
