This 2011 S197 Ford Mustang Ran 212.9 mph at the Texas Mile
Breaking Bad
How
does a Mustang enthusiast set a land-speed record? It’s not as if you
can buy a 200-plus-mph car right off a showroom floor—unless it’s a
Bugatti Veyron, but that’s another story, one that involves a really big
bag of money.
No, breaking bad in a Mustang requires a deep
penchant for performance, plus a lot of hands-on experience and
breathing heavily on the engine with an insane amount of boost. Just ask
Greg Turner, who set a 5.0L Mustang record at the Texas Mile in March
2015. He says, “My motivation for standing mile racing came from nothing
more than my lust for speed.”
Turner admits that his passion
initially found an outlet on some backroads, running triple digits on a
motorcycle. Later on he had a 1995 Cobra with 347ci stroker, pumped up
with a Vortech T-trim centrifugal blower to deliver 575 rwhp. He owned
that Mustang from 2004 to 2007, but with the new 5.0L Coyote Mustang
coming out in 2011, he says, “I knew I wanted it, so I bought one.”
Within
the first few weeks of ownership, Turner bolted on a 2.8L Kenne Bell
twin-screw supercharger. Pushing 18 psi, the blower raised the power on
the stock engine to 750 rwhp. With this output, he nailed a 9.02 e.t. at
154 mph in the quarter-mile.
Such
a stratospheric level is not all that unusual among other Texas Milers,
such as heavy-hitter Shelby GT500s with 3.6 and 4.2 Kenne Bell blowers.
Raising the psi is a relatively simple matter of increasing
supercharger speed by changing out the pulley, but the devil’s in the
details. For instance, Turner also runs a 20 percent overdrive ATI
balancer and a 4-inch upper pulley (the largest size available) on the
Kenne Bell blower case, using an eight-rib drive system.
“The
overdrive crank pulley is really there to help with belt slip,” Turner
points out. “The bigger crank pulley gives us more surface area to
maintain traction for the belt. In turn, we have to run a larger
supercharger pulley to maintain the same overdrive ratio.” As for the innards of the block, Michael and Denise Rauscher of L&M Engines kept the displacement at 300 ci but installed Manley rods and 10:1-compression-ratio Diamond pistons, which is down slightly from the stock 11:1 ratio to handle the forced induction. For sufficient fuel flow that keeps up with the torrent of air, the injectors are 2,000cc units from Injector Dynamics that are fed by a trio of Walbro 465 pumps.
Jon
Lund Sr. of L&M Engines remotely calibrates the engine computer
with new fuel maps by using a proprietary device called a Lund Racing
nGauge. “This device allows Jon to email me the tune,” he explains. “I
load it into the device and we communicate via the web during this
process.”
L&M slipped in custom camshafts with a street/strip
profile (245/250 at 0.050 inch) that actuates Ferrea valves. The
builder also added some additional support for the water jacket, to make
sure the whole enchilada wouldn’t tear itself apart. Also, to prevent
cylinder detonation, Turner runs only premium-grade, 117-octane C16 race
fuel. Venting the burnt mixture is a set of American Racing stainless
2-inch headers that flow through GT500 mufflers. All told, the engine
pumps out 1,252 furious horses, verified on dyno pulls by Kenne Bell.
The Circle D torque
converter is designated as a 1C, which is actually a very mild unit.
“There’s no need for a high stall-speed converter because the car makes
so much torque throughout the entire powerband,” Turner explains. “It
drives much nicer with a tight converter than a loose one.”
Truth
be told, there is way more to setting a record for top speed than
installing hardcore hardware and software—and that wasn’t even Turner’s
initial plan. “The car was never built with the intention of running it
in half-mile and 1-mile events,” he admits. “It was originally intended
to be a quick quarter-mile drag car/street car.”
As
Turner’s speeds and expertise increased, however, his performance goals
began to change too, requiring some modifications to the exterior. In
addition to a Cervini’s Cobra R hood for extra clearance, he had front
aluminum work done on the nose to improve the aerodynamics. The aluminum
was fabbed by his good friend Brett at Nimmo Machine in Costa Mesa,
California. After seeing the masked front end, Jim Bell of Kenne Bell
dubbed the car “Hannibal” after the cannibalistic fictional doctor.
Fittingly, it turned out to be a man-eater as well.
“I ran the car at a local half-mile event in 2014 and went 184 mph,” Turner recalls. Feeling emboldened, he decided to pursue his passion even further. “Naturally, I figured it would have to run 210-plus mph with an extra half-mile, so I made the haul to Texas for the mile.”
He says, “Next I
needed a 180 to 200 pass. I ended up running 206 mph and getting hosed
by the race director for ‘breaking out’ [of the bracket].” So he made a
third run around 190 mph to satisfy the director. After finally being
allowed to run all-out, the car went 212.6 mph. Shortly after, he backed
up that run with 212.9 mph. Mission accomplished!
Surprisingly,
Turner says, “During the weekend, I never did anything more than dump
fuel in the car.” Well, he added some ice too, into a custom 14-gallon
cell in the trunk with a Meziere 55-gph external water pump and AN-16
line up and back. (The nitrous bottle next to the tank is not hooked up
and really not needed given the engine output.)
“I stopped the car on the
bone-stock brakes at Texas, and never used the chute,” Turner says. “I
only pull the chute with the skinnies (17x4.5 Race Star wheels) on the
front at the dragstrip, as they don't provide enough traction to haul it
down.”
While he didn’t run into any mechanical issues at the
Texas Mile, last August the ring gear blew apart, destroying the
differential and twisting the axles. “That is why I upgraded to the
35-spline axles and spool setup from the 31-spline and Detroit
Truetrac,” he points out.
He adds,
“This particular car is surprisingly easy to drive. It did wander quite a
bit on the big end, but this is mainly due to the surface conditions at
the Texas mile. I made a damper adjustment to settle the car down over
the bumps and ruts after the 212.6-mph run. Keep in mind the car has no
front sway bar, and is fitted with BMR drag race suspension. It’s not
ideal, but it works.”
You can’t argue with success, or breaking bad on the Texas Mile either.
