Here is a dyno chart from a 2001 Tacoma SRunner. The truck was completely stock except for the TRD Supercharger. I installed our fuel kit and removed the air box elbow. The max increase in HP was 46 HP. The max increase in peak HP was 33 HP. The result may have been more dramatic if it had headers and a free flowing exhaust.

Any of three potent engines go under the hood. Two-wheel-drive Tacomas get a 2.4-liter four-cylinder base engine, rated at 142 horsepower and 160 foot-pounds of torque. Tacoma 4x4s and 2WD PreRunners earn a 2.7-liter four with 150 horsepower and 177 foot-pounds of torque. Standard on Double-Cab and optional on Xtracab models is a DOHC, 24-valve V6 that whips out 190 horses and 220 foot-pounds of torque. With V6 power, the Tacoma can tow up to 5,000 pounds when properly equipped. A supercharger is available from Toyota Racing Development (TRD) for the V6, boosting output to 260 horsepower. Ask your dealer for details.
