Bring up track-driven or track driving Mustangs, and you’ll likely find two camps… the camp that says Mustangs are useless on track because of [insert any number of limitations] and the other that says it is the best out there and all it needs are a few mods. The reality, however, is somewhere in between, as is always the case with hyperboles. That’s where the Mach 1 comes in.
Tremec in, Getrag out
After over 11 long years of customers complaining and griping since the first generation Coyote 5.0 litre V8 showed up in the MY 2011 Mustang GT, Ford has finally returned to Tremec for a trans to put behind the 5.0 litre V8; a Tremec 3160, same unit as the one in the Shelby GT350 and GT350R, although ratios might be different. That “somewhere in between” has all of a sudden got much better.
Regardless of the reason, the departure from the MT-82 is something that cannot be overstated. Ford has made several special editions and performance packages – namely Brembo, Track Pack, Performance Pack, and Performance Pack Level 2 – that all kept it and even a couple of fairly special models like the Boss 302 (S197) and the Bullitt (S550 using the revised MT82-D4) that all still kept the trans, which makes this switch even more welcome. And that’s not all.
The Good Stuff
Sift through the marketing mumbo jumbo and you’ll find lots of good upgrades. Another complaint from quick drivers is heating issues on the PPL2, particularly the rear diff. That should be no more at least for street cars (i.e. not race prepped). The new one will finally come with a diff cooler, another first for a 5.0 litre Mustang. Trans also gets cooling and there is increased oil cooling by 50%, with increased capacity in the form of an air to oil heat exchanger instead of relying on the coolant to oil which some people call an “oil heater” since it can’t keep the oil cool if the coolant temperature isn’t low enough.
And as usual, you get a whole bunch of suspension improvements namely:
– stiffer anti-roll bars
– stiffer front springs
– recalibrated ABS, power steering, and AdvanceTrac,
– retuned magnetic dampers (MagneRide in Ford speak)
– stiffer rear subframe bushings and toe links from the GT500
– 6-pisten brembo front calipers and larger brake booster from the PPL2
– revised spoiler/pan cover with additional underside airfoils and passages to increase downforce and brake cooling
– 22% more downforce than the standard GT with the Performance Pack
– 3.73 rear end with Torsen LSD
– strut tower brace
– stiffer steering shaft
– 19×9.5″ front and 19×10″ rear wheels wrapped in 255/40/19 and 275/40/19 PS4 tires
– Dual mode exhaust with quad tips (worth the price alone for the noise).
To go with the added grip, cooling, and downforce, Ford slaps the Shelby GT350 intake manifold on to help breathing and power goes up to 480 hp and 420 lb-ft torque which matches the Bullitt. And of course, prerequisite Mach 1 cues including decals, logos, dash plaque, cue ball shift knob, and subtle features so it can be called a Mach 1. Ford says this will be the most capable 5.0 litre ever and I have no doubt that will be the case. They are heading to dealers in Canada and the US now, and it probably won’t be long before one of them pops up on your local track. I just hope Ford makes enough of them and dealer mark ups don’t stick around…
