PizzOnFord, why should they have SC the WS6? The f-bodies were beating the Cobras back in '01, and it's not like they had a crystal ball to look into the future to see what the '03 Cobra would do. Besides, GM wouldn't let the f-body be regarded higher than the vette. Yes, the Mach 1's deserve respect, unlike the GT and Bullitts.

And BTW, the LS6 block does nothing for performance.

WS6snake-eater, a catback is definetly worth it IMO. Only lose a little bit of power vs a cut-out with a free flowing one, and it sounds great all the time.

Leave the cut out open, all the time. It sounds great too. I'm also looking at dollar to HP ratio (the kid said he didn't have much money). It is the best bang for the buck out there. I mean $55 installed for a legit dyno proven 25 rwhp? How can you beat that? I do agree there are some good sounding catbacks out there, I just don't think anyone should have to pay $550 for a decent flowing one. Just my .02

on average we only see the stock ls1's run 13.50's to 13.80's.sure there is your ocasianal fast one from both sides but i am talking on average.

I call BS, if both cars are driven equally the TA will win every time. Were talking cars that weigh about the same. The difference is the TA has 340 horses and 350 lbs. of torque at the fly, the Mach 1 has 305 horses and 325 lbs. of torque at the fly. Also as a pushrod engine the LS1 delivers alot more torque in the low rpm range. The DOHC 4.6 delivers must of its power in the mid to high rpm range. By the way, average LS1s run 13.0-13.5 stock with an average driver. With a good driver your looking at high 12's

No disrespect to the Mach 1s, just stating stock for stock, the TA should have the slight edge

Its a drivers race. Both cars ,stock for stock are about equal. I would start with an air lid and asp pulley on the t/a. A cutout does do wonders for them also installed at the back of the passenger side door. And most of all, Nitto drag radials. YOu cant win if he beats you out the hole. The list goes on and on from there.

well a buddie of mine has a mach 1 with off road h-pipe and hooker mufflers and the best he could get on street tires was a 13.6 -13.7 @105 mph. i drove a friends lt1 the same day and got a 13.7 @ 103. my car is stock with an exhaust system being the biggest mods and i ran a 12.38 @114 mph. i cant even heat my tires because my clutch will slip. the mach 1 is a nice car and all but it wont run with an ls1 in my opinion.not from what ive seen.

silverbeast.....find out what your friends shift points are at.when i first got the mach i assimed it would want to be shifted around 6700 or 6800 and all i could achieve out of the car was 13.70's.then i changed my shift points to 6100 and all of the sudden it went low 13's bone stock with spare and everything still in the car.

no b/s here just stating what we have seen.one guy we know with just weight removal (passenger seat,rear seat and spare)and shifter went 12.80's with his mach.

bottom line is it's basically a drivers race with slight advantage going to mach STOCK FOR STOCK!!!.when modding begins its a diffrent story.

No sense arguing hear, but F- bods have gone 12.8 (GM High Tech Performance) right out of the box with all the interior intact. I still dont see how the Mach1 could have any advantage, especially when you look at the facts that are represented in the numbers. But Im not expecting someone who owns a Mach to admit that. Everycar magazine I have seen shows the Mach going 13.7 (see Car and Driver). I have seen many general car magazines (Car and Driver, Motor Trend, etc.) get the f-bod to go 13.3's. Bottom line is the 4.6 will lose as a result of not having low end grunt, I have heard this from countless magazines in the past that tested the previous Cobra (4.6 305 horse N/A), SS, and WS6

Its a shame your live on the other side of the country, I would race you with my BONE stock TA to prove my point.

Roger- I shift my '03 Cobra right at 6,000rpm. I thought for sure it would want to be wound up near 7 grand. Multiple dyno graphs prove otherwise. LS1's like to rev. From what I've seen, 4V Mustangs don't.

As you've probably noticed, factory ratings mean little to nothing. A 305-hp rated 98-99 LS1 puts down around 290 RWHP on the graph.

You sound like a 15 year old, talking about these horsepower ratings.

Track times don't lie. Many Mach 1s have been at bottom 13s bone stock, i'm talking 13.0-13.1 ... they are very quick 1/4 cars.

Horsepower ratings mean nothing. Track times are everything.

Exactly, the LS1s are GM underrated at 305, but dyno between 290-300 at the wheels making it 340 horses at the fly. And your right track times don't lie, many LS1s run the same time. So how the Mach could have the edge is beyond me. By the way numbers arent everything but they are a pretty damn good indicators of who should win if drivers are equal. Mach 1s are not slow, I never said that, but the LS1 should have the edge, I have three friends who are journeymen at Ford, all with built late model stangs. I asked them who they thought would win a race between a stock LS1 and a stock Mach 1. They all say the LS1 would win.

Gee, I guess that makes it official.

Damn phoenix, your one funny guy.

WhitePheonix, first off, you say that because the LS1 dynos at 290-300 that it then makes it 340 at the fly. Uhhh, that all depends on the efficiency of the motor. You cant take dyno numbes and make a pinpoint fly wheel HP, cuz you dont know the efficiency of the motor. Every motor is slighltly different.
Second, I think you are putting too much emphasis on numbers. It is mainly a driver's race. Both cars have been know to go about the same speeds stock, so it really comes down to drivers skill. IMO at least.

I agree, it would be a drivers race and would be very close. I thought the differences between the two cars would give the TA the edge, but the differences probably are not enough.

Exactly. Who cares what someone SAYS would, should or could happen? That's what I meant by my "smartass" comment. Just because a "subject matter expert" SAYS it would happen, like the doctor saying you have six months to live, it doesn't make it so! Glad you agree.

my buddy has a mach 1, dynoed pretty damn high. 285rwhp and 311rwtq. My car eats oil and gas and is a pretty weak ls1. i dynoed 296rwhp and 306rwtq with a lid, i have cutout now also. Its def a drivers race, but i think on avg as the speed increases the ls1 will take over, stang is easier to launch out of the hole, but most ls1s will catch up. I think machs can eat me all day, lol, my clutch is stock and theres no slipping it at all, so i know its going and my car just has weird issues noone can explain!
