yes its the s1025 except with a 3.05 upper pulley instead of the smaller 2.85. The 3.05 pulley makes about 1 maybe 1 1/2 less pounds of boost, and allows the hawk to take the timing with the lower grade 91 octane fuel.
Seems like if anything it should be called the C1000. C1025 doesn't make sense as the larger pulley will lose about 40 hp. Not sure if the OP mentioned any of this, I have the moron blocked.
