Gt500 Bolt On Test
|
As we suspected, K&N's AirCharger makes a great deal of bolt-onhorsepower. It's important to note that with our 91-octane fuel and lackof catalytic converters, we saw that the engine's air/fuel mixturebecame alarmingly lean at wide open throttle, with the spark plugsgapped at their stock 0.040 setting. This problem is easily corrected byusing colder plugs or gapping the stockers down to 0.030 or so, andmaking timing and fuel adjustments using SCT's XCalibrator 2 flash tunerand the dyno's wideband.
