Yes we are porting the Eaton superchargers, and getting some very good results. Up to 35rwhp on Cobras, and 25 on the L's and HD trucks.
We do not have an exchange program. A customer who has a new or low mileage vehicle doesn't want to exchange his s/c for one that has 30-40-50K miles on it, so we do request you send your own to be done.
Although this creates some downtime for you, 7 to 10 working days as it sits right now, at least you get your own s/c back, and not an older or more abused (possibly) one.
Let us know if we may be of service to you.
