JUN High Lift Exhaust Camshafts has be released

BGTV8

RJN Motorsports in the UK claim 440hp out of their GT4 370Z race car .... with replacement induction system, cams, ECU and headwork (to remove VVEL).
They have no said so, but I suspect they are using GT300 series NISMO heads and NISMO cams. My research tells me this wil deliver ~440hp @ flywheel but not much more.

Wouldnt Replacement induction system mean turbo or supercharger? I am confused.

Nope - when I say replacement induction I refer to the inlet manifold, throttle bodies and re-sized inlet valve-size (increased by 2mm).

Adding s/c or TT means "forced induction" to me - I apprecaite it could be a tad confusing, that could be because I'm a dinosaur (too old!!).

GTM list a VQ37 engine with heads that flow 330cfm which will deliver ~500hp at the crank - all I have been able to do with VQ series heads (not the VVEL heads though, but earlier variable valve timing from JDM VQ30-series engine as the combustion chamber shape gives 13:1 CR with std VQ37 pistons) is 280cfm which matches the RJN Motorsports claimed power.
