This GT500 has been worked on by PAS previously as we installed a smaller blower pulley, idler, and some exhaust goodies.  But, after the new wore off of 500whp more was needed.  Soon, a 2.9L Whipple landed at our door and shortly after the keys to the GT500 were handed over.  A big blower and a set of injectors later this GT500 can enjoy its newly found 140whp after a custom tune by PAS.

The owner was quite happy and we may even be finding more horsepower later as a smaller pulley can always go on the end of this Whipple’s snout and we’ll be deep into the 600′s.
