Here's more info about it: http://greddy-usa.blogspot.com/2009/...0z-coming.html

"On SP's dyno the base Tuner Kit with the optional pre-programed emanage Ultimate fuel kit and full dual 70mm Turbo Ti-C exhaust the Z put down a healthy 449.5whp! at just 0.45kg/cm2, on a conservative 91 pump gas tune.

Not only is it great on the dyno for a stock VQ37HR engine, but its also a great ride on the road. We have been breaking in our new GTR in stock form and we think this Tuner Turbo kit for the Z feels even more fun!"

Finally a video! I'm really liking how the FI market is panning out for the Z.

The Ti-C sounds mean

Very good initial results. Sounds like they are starting to make some good progress.

Buddy Revell · 09-22-2009, 09:00 PM

Is 0.45kg/cm2 6-7 lbs. of boost?

Valentino · 09-22-2009, 09:54 PM

Finally a full throttle video, and a Dyno sheet For a 370z TT

I'm suprised at the Dyno graph.. with most turbo cars the tq. comes on real strong and then tappers out at the end. It looks like with the vvel it some how even with the turbos kicking in keeps the tq flat and straight.

It's changing the duration/lift - it makes sense in a way...it'd restrict the amount of boost the engine will allow in the cylinder...and the rest would be blown off?

That said, I don't like how the dyno starts at around 3.5K, and given that, it'd show a lower low-end torque.

If a turbocharged car has a flat torque-curve, it means the turbos are too small.

450 RWHP on ~6.4 PSI with I'm assuming only their turbo-kit, exhaust, and a tune is not too bad.

heres a pic of an EVO X with upgraded turbo.. I was expecting the Z to have peak HP and TQ closer to the same numbers, with a kick your *** tq curve like this

Not to mention that graph is off a dynapack so just lop off 10%

It sounds INSANE!

CBRich · 09-23-2009, 07:25 AM

I think 6-7 lbs seems like a good spot to keep things tame enough for the street and still have a little added fun.

Agreed. My friend's GReddy TT on his G35 hauled *** at only 6lbs boost. Not to mention sounded like a damn rocket.

I found this pressure unit conversion tool and table. So basically, the Greddy kit is running 6.4 PSI, as some have already mentioned.
