Endurance road race FD3S with GCG HT12-3kai high flow stock turbo on mustang dyno
his is my endurance road race car rx-7 with stock port, motec m4 ecu and snow stage 2 Ai injection 30/70 and pump gas
the reason stop boost at .9kg at 7200rpm is the injector already pass 95% duty cycle and dont want to risk it, and some how this mustang dyno read extremly low number 280whp. but relstatic my friend who dyno his TD06-25G not that long ago in same dyno made the same number like i do.
so this is close to 400hp at engine!! and after all dyno number dont win you any race !!
plus is 100% bolt on new turbo unlike my tire stock

what is GCG turbo exactly? are they part of Garett or a separate company?
where would one get GCG stock twin? the numbers do look impressive.

GCG turbo is a distributor.
The turbos in question were built as a custom order from Hitachi (the original FD RX-7 turbo manufacturer).
