Ok last night I went out to watch a race between these two cars. It was a 01' Z28 with H/C, bolt-ons, 3.73's, M6 against a 04' Mach1 with H/C, bolt-ons, 3.90's(I believe), M5. They were both on ET streets and racing the 1/4. The Z28 would straight stomp that Mach1 though, By at least 6+ cars everytime. I know they were both tuned and that the Z28 had 461rwhp and 441rwtq. But people are usually saying how these two cars stock are a great race, but when it comes to modding, does a LS1 get that far ahead?

Anything can happen on the street, no matter what the setups are...I guess I'd have to know more about the Mach and it's driver


I hope this thread doesn't get to ugly...

yeah anything can happen on the street, but the Machs are not too be taken lightly, they are pretty fast, i dont know what the deal was with that one.

You know its gonna get ugly real quick, just like evetry thread that involves a Mach 1 and an LS1.

It is becuase of the 'modular' design. They do not utilize the cams like a pushrod does. Not to mention, there are ALOT more options out there for pushrods cams than there is Mod cams.

Pending setup...that mach could be as low as 350 RWHP, and as high as 400+ RWHP. Either way. A 281 CID Mod motor isn't going to see 450+ RWHP N/A "very easily", if at all.

Basically: Design differences.

rk - no need to get ugly.

the z28 could have also had a much more radical set up than the mach 1

i wouldnt expect to see as high of gains from H/C in a mach 1 as i would an ls1. its already a 4V head and i remember one of the big mags doing a cam swap in their 98 cobra and they only got like 20hp or something (point of the story is i dont remember it being high), and the 281cu isnt helping it at all .

Jester

The 4v motor needs a different intake to compliment the cams too. The stocker 'suffocates' the motor to death at higher engine speed where the 4v's hp curve should continue to rise well past 7,000+ rpm.

Just for reference, with my H/C/I setup I ran 382 rwhp with a very lean tune.

Nothing light about a H/C LS1. They are mean...

Thanks Mike for the hard numbers........and that is with a Sullivan Intake? or the FR?

Id love to have a 400Hp N/A mach with some 4.56 gears, that would be moving

You know it will. Mustang haters lurk in every thread, even if the topic isn't even about a Mustang...someone still throws a "Mustangs suck" phrase in there.

But to answer your question...more details are needed on both cars. The LS1 might of had a more radical H/C setup than the Mach 1 guy. Who knows, maybe they both made similar power, but the Z28 driver was just one hell of a driver, while the Mach 1 guy isn't the greatest shifter. But more details are needed on both setups.

What kind of heads and cam package on an is laying down 460 on motor alone. Whatever that is, it must be a BEAST! Sounds like MS4 and some very expensive, extremely high-flowing heads. I rarely see more than 435 on a H/C LS1 without a fast 90/90 setup.

Modular motors need a little boost to make up for there small CI

they may run similar stock, but built, the LS1's potential is far greater than any mustang motor of recent. the mach 1 doesn't have the displacement or the liters of the LS1. once you start modding internals, the LS1's displacement advantage really shows as every internal modification will be greater on an LS1 than a mach. that and, as it was already said, the LS1 is a pushrod motor and has a lot more cam choices than a mach. the LS1 is simply a better motor, hands down, no question about it, and modding it will show that for sure.

RED04Z06

Sorry!!!, Forgot to mention Z28 did have a 90/90 set-up, and the Mach also had an intake also. I remember I was forgetting something about the two cars. And the Mach has Stage 3 cams, that is all I know.

Mach1Mustang

wow you are so right. the sc cobras suck......
when you mod anything it comes out to how much you want to spend, the ls1 is much cheaper to mod, so it can make more power cheaply.

Angus66

If the Mach had 3.90's in it, he's either set-up for running primarily on Nitrous or made a really bad choice when it came to selecting gears.
(Possibly both now that I see what cams the Mach is supposed to have)

3.90's are great for a sprayed 4V but I myself would go no less than 4.56's if I was planning on running N/A with a cammed/worked heads 4V.

I would also like to know the intake manifold that is on that car - the stock intake manifold doesn't like to make good power past 6300/6400 rpm due to it's relatively short 11" runners.

11" runners + stage III cams = engine combo that isn't even close to making it's best rwhp.

By "intake", do you mean a cold-air intake or an aftermarket intake manifold?

ChocoTaco369

wow. are you being serious? you're going to talk about SUPERCHARGED cobras? throw a similar blower on an LS1 and run it at the same psi (assume the LS1 bottom end can take it). what happens? can you say "cobra gets annihilated"? were you making a joke? i'll assume so. a procharged LS1 will make a lot more power than a cobra at a greater psi. now throw in a blower cam - which we have WAY MORE VARIETIES OF - and the gap widens even more. then come new heads and the LS1's displacement comes into even more of an advantage. just give up.

I have yet to see or hear about a Mach1 making 400rwhp??? and it's funny to see even on a LS1 based website the mustang is defended and honored! to all you stang fanatic's looking at this thread, they are trying to organize a LS1 vs stang shootout in the DFW area so either "let your nuts hang or stuff them in your mouth!"

WRX-ERROR

Saying a H/C anything really doesn't paint a good picture. Take two stock ls1's and put two different h/c combo and the difference could be 2 to 3 cars easy.

Besides, without FI it all comes down to pure displacement and the ls1 has a lot more of it.
