GTM 370Z 1000HP MAF CALIBRATIONN -ANOTHER MILE STONE
We would like to share a mile stone we've achieved regarding the stock ECU.
Over the last few months we've been working on developing a way to overcome
one of the limitations of the stock ECU when it comes to making big power.
While Uprev enables the aftermarket to rewrite the stock ECU in the
370Z/G37, there have been a few hurdles to jump when pushing the envelope
over 600whp. Since day one, we always kept in mind that people will only
want more power. In anticipation, we chose to use 3" MAF piping in all of
our turbo kits and the GTM Stage 2 Supercharger Kit. Doing that gives us more
headroom when it comes to MAF Voltage. It's a mechanical calibration that
allows us to get the factory MAF to read more airflow. Even at 600whp, the
MAF voltage is getting up to 4.9 to 4.95 Volts. While this is still below
the 5 Volt limit, it does not give us any headroom to compensate for
changing atmospheric conditions (such as a cold morning). The next step was
to find an aftermarket MAF sensor that can replace the factory Nissan unit
with the same physical dimensions and connector. Of course, that was the
easy part. The challenging part is to produce a good calibration that
contains a linear MAF curve so we can get the best resolution and still
plenty of headroom for more horsepower while retaining
factory drivability. This development translates into having a 1000hp car
that starts up every time and can be driven normally on the street.
Ultimately, this has greatly expanded the capabilities of the factory ECU
to the level of performance commonly relegated to a standalone EMS. While
some standalone EMS options may have some additional features that set it
apart, we've really narrowed the gap here.
To close the gap altogether, we are working on developing a system that
will enable us to retard ignition timing in response to knock as well as Boost cut. Once that is developed,
there will be no reason for a standalone EMS in this platform.
The STILLEN 500 HP Supercharged Nissan 370Z - /TUNED
TUNED Visits racing legend Steve Millen's STILLEN in Costa Mesa, CA to see
what happens when he gets his hands on the Nissan 370Z. Already a potent
machine, what happens when STILLEN upgrades pretty much everything?
Fortunately, it doesn't suck.
KraftWerks Performance Group is proud to bring you the most advanced Supercharger system available.
At the core of each KraftWerks Supercharger kit is the revolutionary and patented
Rotrex, traction-drive Supercharger. The
proprietary design allows for reduced weight; smaller, quieter, cooler
operation; and shaft speeds in excess of 200,000 rpm. No other forced
induction method can compare to Rotrex's superior efficiency, unmatched
performance, reduced emissions, and transient response.
KraftWerks Supercharger systems are
designed to deliver broad, usable power gains—ideal for street cars and
track cars alike. No other Supercharger
kit or turbocharger system can compare.
KraftWerks Supercharger kits represent
the pinnacle of forced induction, having demonstrated gains in excess of
100% across the entire powerband on a number of applications.
Each KraftWerks Supercharger kit is
designed in-house at our state-of-the-art, Norco, Calif., facility with
applications available for a variety of vehicles.
Girl's first time with 800 horsepower under her Butt
Friend takes her first ride in my Z.
This is my 2006 Nissan 350z.
Made 822rwhp & 751ftlbs at 26psi on e85, then the Exedy triple disc clutch
Currently sitting on wastegate pressure (16psi) making 608rwhp 525ftlbs on
e85. All numbers on a Dyno Dynamics Dyno.
Redline is 7600rpm. Tach is off, shift point on actual tach is after the 8k
mark. As you can tell, never went to redline.

Forced Induction - Supercharger vs. Turbo Charger
This video was made to describe in moderate detail the differences between
Superchargers and turbo Chargers, as well as describing the
components, advantages, and disadvantages to each. Complementing the
speaking track is a slideshow of related pictures and videos. I hope this
video helps some of you curious up and coming mechanics to better
understand methods of forced induction. Please comment maturely, and
