I think that blower may not be considered aftermarket and still at the lower factored HP. The classification guide seems to indicate the higher HP is for a VMP blower.

Other than reaching out to NHRA Tech (which is pending), how would a person go about confirming for sure what horsepower rating the DR3Z-6F066-A supercharger carries? It is listed in the NHRA Guide as the "Alternate" supercharger. Would not the "Alternate" supercharger listed be the one that requires the higher rating?
EDIT: I see now that the "&" symbol under the various engine/trans combos refers to "& = VMP #VMPG3R-6H066-AA-23". As a non-CJ expert I did not recognize that as a supercharger model # and it would have been nice to have that info included on the page, and/or the "&" put after "S/SS Factors w/ replacement supercharger". Without that clarity I'm still somewhat unsure where the higher HP rating applies. If someone runs this combo with the DR3Z-6F066-A supercharger and can verify which horsepower rating it techs and races under that would be most helpful, otherwise I guess I'll cross my fingers for a clear answer from NHRA.
