Big thanks to Ross and his team at Ripp Mods for hosting a dyno day for the NYCCDSM members (Eclipses and Talons) Turno out was bad, but Ross and his team did a upstanding job.

Okay too my baby on the dyno again and she laid down 411, 409 and 408.

She seems to be breaking up on the top.

Previous Mods: Red Lines
R34 N1 swap
Nismo DP
ARC 100mm ti exhaust
uprated ecu
m's intake

Current Mods: Blue Lines
HKS 2530's
ATTKD 76.5mm o2 housing (turbo extensions)
Greddy 5 row IC

How's she looking?

Next round of mods:
HKS 264's
XS Engineering Power Pack II
Apex Racing Plugs heat range 8
Nismo 555 injectors
Aeromotive FPR
Blitz SBC

Aiming for 475+ whp.

John

So you're getting about 410 atw at around 1 bar boost ?
Looks pretty good - I think your future mods will increase the power and the turbo spool up should be helped at the same time.

Yeah, the lag may be due to IC piping leaks. It's going tomorrow for new pipes.

Thank you. Yeah, that's what's got me a bit worried. Perry (the tuner) is saying it may be detonation. Which it could be the night before she didn't even want to run because she was so rich from the IC piping leak.

I'm hoping for a overall improvement, but going to say the Greddy IC is a overkill and causing a huge lag.

The movement on the graph is down to the load control on dyno dynamics, it is down to the attessa shuffling the power on/off to the front diff.

Would it be better if I turned on the Grid TS Dancer and split the load 50/50when on the dyno?

Thanks guys so I guess the Dyno Dynamics will not be good to tune a GT-R with :(.

hi john. the way i understand it is a more power is demanded usually at the higher end of the rev range the gtr,s attessa system decides which wheels need drive which in turn causes a major problem for the rollers. hope to get mine on a dynopack week sat so we will see and i will post that graph hopefully.. bernie.

is it not a little rich at the top end?

I thought 12 AF ratio was good for the top end range?
It is still rich I don't have any aftermarket fuel computer in the car, it ran on the remapped ECU (not sure what the specs are)
