Intake comparison
Just dynoed a ls-1 427, first with a tpis modified oval ls-6 intake and throttle body, average hp was 598 and torque was 573[4300 rpm-6500 rpm] then a lsx 90 intake and throttle body was tried ,average hp was 585 and torque was 570 a/f was identical for both tests the lsx made 10 more peak hp[659] but lost some torque, Just something to chew on.
