On the dyno, we made our initial base run without nitrous. Our peak horsepower was 84.1 at 4,300 rpm, and peak torque was 105 lb-ft at 3,900 rpm. We followed up with a nitrous run with a 50hp nitrous setting. On the nitrous run, peak horsepower jumped to 110.8 at 4,400 rpm, and torque output was 145.4 lb-ft at 3,900 rpm. That's a gain of 26.7 hp and 40.4 lb-ft of torque at the wheels on a completely stock four-cylinder S-10. If you account for a normal drivetrain power loss of 15-20 percent, this means we made more the 50 hp at the flywheel and easily surpassed 50 lb-ft - and we all know that torque is what moves a truck. Looking at the dyno chart, the power gain was consistent across the entire rpm range. We don't know of any other modifications available for the money that can add that type of power to an S-10.
