The new BTR Big Twin Turbo cam was designed for use on 76mm or larger twin turbo setups or single 102-106mm turbos in 400-427 cubic inch combos. This cam was designed for use in high horsepower applications looking for more power and higher rpm , and offers an ultra-aggressive idle. This cam has the potential to push a 400" engine well over 2000 rwhp and into the 6 second range in the quarter mile. This cam uses ultra stable lobes for higher RPM potential, and was designed to be extremely durable at high rpm when combined with a lightweight valvetrain.
Due to higher rpm potential combined with greater cylinder pressure from boost we recommend the use of our SK703 spring kits and larger diameter hardened pushrods along with a quality lifter such as a Johnson ST2116LSR or ST2126LSR.
