Be careful with the fluid you use in the blower. Paxtons require a fluid that has at least some friction. Too slick fluid allows the planetary balls to skid rather than roll smoothly which can create heat spots and cause early failure. Original fill was Type A Suffix A which was made from whale oil and is no longer available…that’s why Ford Type F or equivalent is recommended today.
Andy Granatelli in his book They Call Me Mister 500 said they used some STP in the blower as it helped keep blower oil temps down…but Andy was a master promoter and that was his product. Besides…how many drive at Salt Flats speeds?
