5.3L LS-Base vs Racing Tricks
After the FAST LSX induction system increased the power output to 482 hp, we couldn't help but wonder what it might take to reach 500 hp? Milling the heads was obviously an option as was wilder cam timing, but we wanted to test while the motor was still warm on the dyno. Reaching into out bag of racer tricks, we dropped the water temperature, changed the Lucas 5W-30 synthetic oil for some ultra lightweight 0W-10 Pro Stock oil and then replaced the 91-octane premium unleaded pump gas for some VP Q16 oxygenated race fuel. After bringing the oil temperature up by making a few hard pulls, we cooled the water temp and the peak numbers jumped right up to 501 hp and 452 ft-lb of torque. Some may argue that these numbers don't represent what can be achieved on a typical street application, but our goal here was to demonstrate what can be accomplished in full race mode (at the drag strip).
