JUN exhaust cam shaft finally arrived

GEMu · 10-26-2013, 02:05 PM

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.

That's actually quite good -- even with headers and a tune. Do you have a link to the dynos, by any chance?

Honestly for me I think it a waste of money, especially for you guys over there with that rate of labor, here in Thailand I would say a cam swap in a Z34 would cost 100USD max, depending on if the shop is famous or not.

Sadly, a friend of mine already sell his car for a 430Scud and had not document his dyno run or keep a sheet, but he said the baseline was 285whp and after all the mods installed he claimed 350whp on dynojet.

20 more whp from normal full bolt ons, for 500USD on cams set and 3000USD on IMPULs plus US labor, you decide if this worth.
