That trap and time is COMMON. It is not a fluke, and with a lid and a cutout alone on an auto it won't raise any eyebrows as being something super-special.

It's a good run. No more, no less.

"Great" runs in stock LS1 F-cars = 12 second timeslips just like "great" runs in stock 405hp Z06's = 11 second timeslips. Guys like Evan Smith and McRat over on Ls2.com can do it.

Those ARE flukes.

 

Once again, I hate to disagree, but that was in a modded Mach. Not heavily modded mind you, but modded none-the-less. If you scroll down the post a bit, you'll find Angus said "4.30 gears, cat-back, catted x-pipe, cold-air kit, bfg drag radials & rear lower control arms.

I also have a Steeda Tri-Ax shifter & run without the front sway bar, but that doesn't add any power... "

 

Just keep telling yourself that. Time will tell

 

Motortrend did a test of Mach 1 5-speed and got it to run 13.2 @ 106.7 mph.

I don't think there is any LS1 that ran that fast with MT.

Having said the above, the guy who ran 12's was modded, and in particularly cat-back exhaust and 4.30 gears helped a few tenths, no doubt about that.

BUT. I doubt that 05 GT will run faster times than Mach I - at most I predict them to be even. My opinion, of course, and I can't wait for the real times.

 

Yeah, everyone with stock wheels does that.....and they spin happily on their way to a mid 14 second run. Heck, i'll even go as far to say that the track was prepped.

I don't have any other mods right now. My warranty is set to expire soon and a good torque converter and some et streets are on the way. ...and most likely, a new read-end too..

I'll easily be in the mid 12s then.

Torque multiplication > You

Is it just me, or does MT seem to favor ford? A 13.6 out of a 320 rwhp SS and a 13.2 out of a 280 rwhp Mach 1......

 

I was wondering the same thing , but I guess Mustangs are easier to launch than fbody. The gearing is 3.55 for Mach I and 3.42 for fbody, so there is not that much difference. SS dynoes quite a bit more at the wheels, yet they run within 1 mph of each other

 

Gearing in the tranny does wonders.
My Tremec x-reference manual shows quite a variety of 1,2,and 3rd gear ratios for the F-cars versus the Mustang. Heck, even the same T5 in Mustangs varies considerably from the 4-cyl version to the V8 version. 4th seems to standardize at 1:1 for all 5-spds, and 5th varies from a .72 to a .88 in the same T5 based on different cars.

Anybody remember back in the early '90s when Dale Earnhardt was walking away from everybody (even his own teammates with identical engines) on superspeedway restarts only to run equal at the top end? 2nd and 3rd gear tranny ratio.

One last thing - don't judge a cars performance based solely on a HP figure. It's like saying "I'm an awesome football player becuase I weight 300 lbs". Well if you are only 5'0" tall, have flat feet, and weigh 300 lbs, you AREN'T likely going to be a great football player, but you sure enough weighed 300lbs!
As someone said earlier, it's the total area under the curve that counts, and the shape of the curve itself. You are much better off getting to max torque ASAP and increasing the area under the curve ASAP in a drag race - especially with stock torque converters in an auto where RPMs start low.

Hey muckz, nevermind comparing the F-car and Mach 1...
Compare the Mach 1 at 305hp and 3.55 gears and a 5spd to the same-year Cobra with (a well-known under-rated) 390hp and a 6 spd! I know the weight is a little different, but not 900 lbs worth.
Why only a few tenths difference there?!?!
One would think the Cobra would dessimate the Mach, but that's hardly the case.

 

I wonder what wonders a looser non lockup converter will do for the new Mustang Auto. With those aggressive 1-2 gears, I could see it putting out nice times with very few mods.

 

I'll wait on final judgement but i see this 13.60 run as a best and not easily reproducible for everybody on the street. The trap doesn't impress, but the 0-60 does.

I also see the M5 running barely significantly faster than the auto. I could be wrong.

Overall, i see this new motor as a continuation of what FoMoCo accomplished finally with a Mach1. Nothing more, nothing less. The suspension will be the best stang ever but i don't expect this car to be a road course king in OE trim.

 

Look at this.

MT tested an A4 Z28 too....

320rwhp A4 Z28 ran a best of 14.0 @ 101 mph

Several runs and all they managed was a 14 second run???

 

People are spending too much time on one set of test results. The atmospheric conditions and traction conditions make such a big difference to 1/4 mile, that you can't just take two tests in isolation within 1/2 second and make a meaningful determination as to horsepower.

Other big factors are breakin miles and driver skill and experience. We don't know what those were, either.

Now, a 13.6@99.9 does indicate a very good start, and you would expect a very good 0-60 time. Odds are that a car that saw 14.0@101, if tested by the same driver on the same day at the same time and same track as the Mustang, would do better than 14.0. So what?

 

It was the same car...at the same track.

 

The new suspension vastly improved hookup. It is better than the last generation mustangs and F-bodies. Power and traction = a good 1/4 mile time. Don't just try to associate power with 1/4 mile times.

Motortrend favour Ford? Humm.....not that I know of.

Motortrend times are never the fastest of the mags. The fact that they are getting such a good time says a lot about the ability of the car to launch well and the excellent auto. IMO, based on past tests, MT times are definately reproducable on the street unlike say, Muscle Mustangs and Fast Fords that ran 12.9x I think with a Mach 1. Few have gotten there.

 

Was traction the same? What about air temperature?
Now, maybe the A5 Mustang launches better than a 2002 A4 Z28. But we don't know for sure.

 

They said the tires made the difference actually.

The brand they were using (Pirelli sp? I think) hooked a lot better than the F1s did during that run.

Honestly, there is no way anyone can do a 2000rpm brake stand launch on the streets with street tires. It's just not happening, they would spin out.
