R34 GTR - 287KW@wheels - dyno attached.

[jezzrrr]

This is the Dyno chart from my most recent mod to my 34 - the addition of the power FC, the difference is remarkable, the torque curve is much fatter than before and peak power has jumped too. Ant at SST is behind the tune which I should say was done in very little time and very reasonably priced.

I reccomend the PFC to anyone with a GTR I have them in both my 33 & 34 now and cannot fault them.

Other mods are:

* bigger intercooler

* HKS dump pipes

* full Blitz exhaust

* Pod air filters

Engine and Turbos are standard as is fuel system which is about as close to being maxed out as you can get.

I am in need of a clutch upgrade that is around the corner and this baby should run a decent time over the quarter.

awesome result. are those AFRs rich? i know the power your making is at the upper end capable with std turbos, but is there more to be had from bringing AFRs up to mid 12's?

hi jezzrrr,

that's fanstastic.. yeh i think you've probably hit your max running std injectors, pump, afm's. However something doesn't sound right, I remember your last post you said 278kw @wheels. So what your saying is you only gained 9kw by installing the Power FC :confused:

It would have been good to see the dyno charts, seeing you had the opportunity to compare the before & after results with the Power FC..

it would've been a great comparison, as even though there may not be much of a gain at peak power, im sure the differing torque and power curves would show that there is alot more area under the curve than there was prior to the power fc being fitted. No point in having huge peak power if you've got nothing for 80% of the rev range.

The ECU that was in it before was a chipped (or VX Rommed) Jap item that ran ok at full tilt but crap everywhere else.

The main gain is in Torque throughout the range.

YES I think the AFR is a little rich and some more can be had from leaning that out ... does anyone have any input on that ?

Well 12:1 AFR seems to be the accepted standard. Running a little richer may not be a bad idea for a street car considering the variable quality of fuel.
