Many Z34 here in BKK did the JUN cam, one of a guy I know installed the cam along with
an IMPUL throttle body and yield around 350whp on Dynojet so it hard to say where did the extra 20-30whp came from.
That Z got a custom stright pipe from headers, F con Vpro3.3 dyno tuned by one of the most famous race car tuner in Thailand, racing suction with HKS filter and IMPUL throttle bodies.
350whp on dyno jet in tropical climate like BKK is not too bad IMO, but the owner said the installation was PITA.
