Does anyone DO turbo crank port cases? Trinity racing did advertise this years ago.
Does it work?
Quoat from old Trinity advertisement
A tubo crank modificaion consists of cutting directional fins into the crank throws, porting the cases, and truing and welding the crank. this modification causes the intake charge to be pulled into the lower end, atomized more efficiently, and then blown through the transfer ports. This modification delivers power through the entire powerband.
