i have been looking on the offical Japanese D1GP web site and have noticed that the Apex\'i, RE Amamiya, and 1 of the other FD\'s run stock ports on their engines. Only 1 FD and 2 FC\'s have modifed porting. Is there a reason they don\'t have porting????

I can only guess but i think they dont need massive amounts of power to drift as the fd is very twitchy anyways so may be harder to drift with even more power ? :Laugh

all porting does is move the power band slightly higher/....drifting doesnt require power at the top end...it needs the lower end grunt especially on more technical tracks...

I don\'t believe that they are making:

Power: 460BHP
Torque: 50kg-m
Turbocharger: APEX RX6 TCW76-P27 Turbine(Boost set-up 1.0kg/cm2)

Without porting, esp at 14PSI of boost - i was running 17 on my RX before the engine died at that was only 360BHP at the wheels...

but what fuel are they using, if it is standard (even Jap standard 100RON) I\'d agree, but I expect they are using race fuel?

Maybe they have some home kept secrets? :Giggle Not unusual for those clear Japanese.
It\'s always been like that in the past. They\'ve always kept the best for themselves, then release them a few years later when they are outdated in the home market.

those figures are flywheel power figures.

Most Jap measures are at the flywheel.

Not hard to get a 450hp ( fly ) fd with bolt on parts.
