| “This
is the fastest street car I have ever driven. It just
plants you to the seat... With the same 14 psi
of boost as the modified factory supercharger [Eaton roots
model], the... ProCharger blower [P-1SC-2] had increased
118 hp... at the rear tires! The boost level was then
set at 19 psi… and this put the final numbers at an insane
646.9 rwhp. Maximum torque reading at the tires was 541.7
lb-ft [an improvement of 184 rwhp and 47.8 lb/ft at the
tires, simply by switching superchargers]."
|
| “ATI‘s
new line of self-contained superchargers looked inviting
to us, and why not? The P-1SC specs read like a veritable
performance recipe for any new blower... Throw
in a three-year warranty, a self contained oiling system,
and an emissions legal, gear-driven design and you have
a winner on your hands. The P-1SC‘s 70-80 percent
horsepower increase is exactly what our 3g GT project
needed to help achieve our 1g of acceleration. Being emissions
legal and easy to install were definite plusses in ATI‘s
favor as well. The final selling point was integral intercooling.”

“On
the first run off the street (and make no mistake, Vaccaro
drove in all the way from Queens), it clipped a 10.77
at 125.44... After a break, it* clicked off a
10.32 at 129.02. Vaccaro was so fired up, he called it
a day. He changed tires and went home, confident no one
would beat his time. And he was right."

ported heads, D-1SC, sheet-metal 3 core intercooler, 15
psi, pump gas

| “They
introduced a 17 psi kit that put stock Mustangs in the
11‘s, and received CARB approval for their intercooled
14 psi system. Not one to rest on its laurels, ATI now
offers their new P-1 and D-1SC self-contained superchargers...
Self contained means that there are no oil lines to the
pan and generally installation is cleaner. In
addition, ATI offers the advantage of intercooling to
provide even greater horsepower gains. By keeping
the air cooler, more timing and/or boost can be used without
the worry of detonation.”
|
| “Imagine
a V6 Mustang with nothing but a supercharger making more
power than a ’01 Mustang GT with a robust V8...
Well, if you compare the apples to apples of the two automatic
equipped cars, you’ll see the ProCharger V6 [stock 3.8L
with 9 psi, 66% increase in power] cranked out 34.8 more
peak horse-power than our ’01 GT... The fitment is nearly
identical [94-98 vs. 99+]... and both are relatively easy
installs due to the self-contained nature of the P-1SC.”
|
| “So
what makes this new blower so much better than the models
that created a tidal wave of ProCharger racers last year?
Well, it starts where most things do at ATI —
with a stronger transmission for improved durability.”

| “Running
the motor on a chassis dyno is not the same as running
it on the street or through the quarter-mile at a local
strip... An air-to-air intercooler relies on
a steady (and large) supply of airflow across the core
to extract the heat... If you have a hard time grasping
how much airflow is present, try sticking your hand out
the window at even 30 mph and feel how much pressure (and
volume) is present. Now imagine the resulting flow at
100 mph... The problem with testing an air-to-air intercooled
motor on a chassis dyno is the relative lack of airflow.
Even the most aggressive fans do not come close to supplying
the air source seen by the intercooler core while driving...
An option [during chassis dyno testing] is to cool the
entire inlet system including the intercooler down and
run... a mist of water to artificially increase the effectiveness
of the intercooler. The important fact to remember
is to duplicate the change in charge temperature [across
the intercooler core] witnessed on the street... while
on the dyno. Otherwise the dyno result will be
suspect [dyno result will be lower than true power during
street/strip usage].”
