Super Chevy – September 2019

28 SUPER CHEVY SEPTEMBER^2019

We ran the boost through

a ProCharger air-to-water

intercooler to help keep the inlet

temps in check. This helped us

push up the boost a bit on our

91-octane pump gas.

24

To add even more fun to the LS street stroker, we installed

a ProCharger P-1X centrifugal supercharger. Capable of

supporting over 900 hp, the P-1X was more than enough

blower for our street engine.

22

The blower was equipped with a 4.25-inch blower pulley that

produced a peak boost pressure of 9.1 psi.

23

Before the installation of the supercharger, we dyno’d the low-

compression 382 stroker in naturally aspirated trim. After the

break-in and tuning with the Holley HP management system, the

382 pumped out 514 hp at 6,100 rpm and 472 lb-ft of torque at

5,100 rpm. Strong numbers for a low-compression LS that could

run on 87-octane.

21

The graph clearly shows that, when it comes to adding power, it’s really hard to beat boost. After bolting

on the P-1X blower, the power output of our 382 jumped to 780 hp at 6,500 rpm and 646 lb-ft of torque at

6,000 rpm. That’s a gain of 266 horsepower over what it churned out in naturally aspirated trim.
