302 POWER:PART 3
serious peak power numbers as
long as we don’t get excessive in
the torque production. To keep the
engine alive and working for thou-
sands of miles, we decided on the
linear boost and powerband offered
by a centrifugal super-
charger. The rising boost
curve might not offer
the torque production of
a turbocharger, but we
hoped it would keep our
stock block in one piece.
To supply said boost, we
decided on the easy-to-
install TorqStorm super-
charger. The TorqStorm
supercharger is capable
of exceeding 700 hp,
so we know it will be
more than enough
for the needs of our
street engine.
Installation of the TorqStorm
kit on our engine dyno required a
few subtle changes. The first was to
space out the crank pulley to miss
our Meziere electric water pump.
This is not a requirement on stock
or aftermarket mechanical water
pumps—just for our dyno test. We
installed the blower mounting
bracket, followed by the crank pulley,
and then the supercharger. These
were basically all of the major com-
ponents, as we also decided to run
the boost through an air-to-water
intercooler from ProCharger. This
was something we had from previous
testing and we liked the idea of cool-
ing the charge air from any form of
boost—even the TorqStorm.
Using different sections of alu-
minum tubing from our stash, we
cobbled together a discharge tube
from the intercooler to the throttle
body. The custom discharge tube
also included a blow-off valve from
Turbo Smart. From a previous test,
the TorqStorm supercharger was
equipped with a 3.1-inch blower
pulley. When combined with the sup-
plied crank pulley, the combination
produced a peak of 10.2 psi of boost at
6,000 rpm on our combination. After
dialing in the air/fuel and timing
with the Holley management system
(see Graph 2), we were rewardedTHE ULTIMATE SOURCE
