Good find.

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, 10:00 PM

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

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

It newer styling along with its refinement makes it a great buy and value at the price point i've seen local dealers selling it for. Very great value* It WILL be stealing a few porsche, vette and BMW buyers...

I'm a great example of this...I liked the Cayman S (but it was out of range), and was in the market for a sports car. The Mustang GT500 was on my list as well - basically I was looking at 30K-55K. The Z came out...I saw the lines of the Cayman S in the car, and it's pricing starting at half as much. I can't imagine myself a Vette owner, or a BMW owner...

Modding it wasn't even in the picture, even when I bought it a few months ago - but, if a SC kit comes out, I may have to reconsider. It's a great debate between warranty coverage if something goes boom or, chasing that idea of having more power, or, leaving it all until my debts are paid off, which, including the Z, might be a couple years....which timing-wise, might be a good thing as all the kinks and bugs should be long gone by then and prices come down...lol...time will tell...lol

And that's not to mention the HEAT. Turbo setups run a helluva lot hotter than supercharger.

Yeah, not to mention the oil being used to cool the turbos themselves, and this car already had a tiny oil heat "issue"

A cooler would be manditory, if you happen to track the car, you might need two oil-cooler cores and chain them together.

one other thing I don't like about turbos is that you have to give them time to cool/spin down after driving so that they aren't screaming and their oil supply shut off, roasting the oil...etc.

I think the key is controllable power. One nice thing about SC's is that it's instant, both with on and off throttle - no spool up time (granted, turbos are getting better spool up times, but, still not as quick!)

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.

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

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.

It sounds INSANE!
