Road & Track Magazine Supercar Tuner

Photos by Guy Spangenberg

A few weeks back we shared on our blog that we were invited by a major Automotive magazine editor for a supercar comparison, well the editor  was Sam Mitani of Road & Track magazine and the challenge was to compare four elite Tuned Supercars (GMG Audi R8 LeMans TT, D3 Cadillac CTS-V Coupe and CEC Mercedes-Benz SLS).  We were happy to represent Japanese Tuners with our 4.3L GReddy Twin Turbo R35 (GR43 GT-R)  And as you can see from the results below, with some help from KW suspension, Whiteline, SP Engineering, Dodson, Rays and Toyo, we did quite well... 

Even with our GReddy stroker 4.3L engine, the 6 cylinder VR43DETT,  had the smallest displacement of the bunch, yet on pump gas (91) tuning with our 94mm Titanium Exhaust, Type-29 intercooler, twin TD06-20G turbo kit, at 25psi, it still made the most horsepower and torque.

But when it came time for performance test, we dialed the PRofec boost controller back to about 20psi, for the car to be more manageable for the magazine test drivers.  Even still the results were impressive.  0-60 in just 2.45sec. and the 1/4mile in just 9.9sec.   Sam Mitani said "...this car beat the $2.7 million Bugatti Veyron Super Sport (November 2011 issue) to 60 mph and to the quarter mile, the GR43 can be regarded as something of a bargain."  (this is the 2nd time we had a driver tell us our GT-R was faster then a Veyron)

The GR43 also had the best 0-100mph time, shortest braking distances (thanks to the TopSecret rotors), and even though the car was more set-up for a short road course then, a skidpad or slalom, we recorded the top Lateral Acceleration of 0.99g and just short of the best Slalom, by just 0.4mph (73.1mph).


Look for the full article "Performance Overload" in the next Road & Track issue.

In car clip of the GReddy 35RX on the Fuji straight

Late last month at the annual GT-R Magazine's R-meeting, we debuted the GReddy 35RX GT-R with a 200+mph pass and Tarzan Yamada at the wheel.   Here is a quick video excerpt of the GReddy 35RX on a practice run (a few days prior) along the famous Fuji Speedway straight-away.

 Turn up the volume to hear the sweet sounds of the GReddy built 4.3L stroker VR engine & Twin TD06SH-20G Turbo Upgrade, in combination with the  GReddy single 90mm to quad 60mm PE-R exhaust.... enjoy!

Look for more footage in an upcoming Video Option Vol.212 feature...

GReddy R35 V2 - 4.3L VR Sound

Here is just a quick teaser of the sound our GReddy 4.3L VR powered R35 V2 makes on low boost & 91 octane fuel.  We'll have more updates in a few weeks about what this was for...but until then; TURN UP THE VOLUME and enjoy!

GReddy R35 Exhaust Line-up

    One of GReddy's most important product lines has always been our Performance Exhaust Systems.  So it was important for us not to hold back on development for different exhaust for the R35 GTR.  A well designed exhaust system is one of the best investments you can make as a GTR owner and the return comes in the form of improved Power, Sound and Style!

Our most recent exhaust system is the fully polished stainless-steel Power Extreme PE-R.  After extensive prototyping and testing, this highly tuned configuration showed great performance increase for factory to boost up applications, as well as stock-frame turbo upgrades.  The unique design features: 90mm (3.5") diameter mid-pipe to 1-4 inverted collector to quad-60mm piping with individual straight-through bullet mufflers and SE style burnt Ti-coated tips for the smoothest flow.

P/N 10123300     GReddy Power Extreme PE-R

The next exhaust options are our lightest-weight (just 19lbs), GReddy Racing Titanium PE-Ti and the more cost effective, stainless-steel version, the Power Extreme GS.  Both of these systems feature the same great design, with large 80mm (3.14") piping throughout (80mm 1-2-4) and large dual straight-through oval mufflers.  The "Tried and True" layout  increases flow and effective sound suppression.  These configurations have been our most popular and versatile applications we offer, from factory boost levels to our 20G twin turbo upgrades.

P/N 10123224     GReddy Power Extreme -GS

And last but not least, after pushing the limits of the of the R35 VR engines, we developed our largest, most extreme exhaust system yet, the GReddy Racing Titanium 94-XL.  With specially made Titanium 94mm (3.7") diameter piping (just about a large as you can fit under the R35 without under-tray modification) we use beautiful, labor-intensive "inch-welding" and V-band connections to smoothly route the huge piping from the 2x80-94mm Y-pipe all they way back to the large dual, high-flow oval mufflers and large 115mm, staggered tips. The exhaust also has burnt Titanium finished Tips and GReddy center logo The complete Y-back system weights just 29lbs. (less then 1/2 the weight of the factory system) Surprisingly enough the  large diameters work well for even stock turbo boost up applications and quiet enough for the street, but the biggest gains come when your pushing the VR engine with turbo upgrades over the 700hp-1200hp mark. (This is what we are using on our GPP R35 right now)

The quest for Eights in a (R35) GTR by Autoweek

Back in May, the GPP staff was out supporting the efforts of one of our GR-Master Tuner Shops, SP Engineering, in their efforts for a GReddy-Powered, 8sec quarter-mile R35.   Although the the track conditions were not quite right for 8s, we have been working hard to get back on a track and go for it again!  Below is a recent article from Autoweek about our quest! 

In AUTOWEEK By DAVID ARNOUTS on 7/20/2011

"Eight seconds can seem either like an instant or an eternity.
For SP Engineering, however, eight seconds is the threshold it aims to cross in its highly modified Nissan GT-R shop car for the standing quarter-mile.
“This car will run eights,” said Will Wong, wholesale manager at SP Engineering. “The problem is traction, getting the power to the ground.” But SP continues to try a variety of suspension settings and tires in an effort to reach its goal.
Even with a full interior and ice-cold air conditioning, the street-legal GT-R pumps out more than 1,150 all-wheel horsepower through the Mickey Thompson drag-radial tires.
Having broken the previously long-held dyno horsepower records, SP went on to hold the world record for GT-R quarter-mile time with the SPE900 GT-R in April 2010--9.62 seconds at 149.8 mph. A stock 2012 Nissan GT-R will run the quarter-mile time in the low-11-second range...
Rival tuner shop AMS Performance of Chicago in May 2011 took the current record with a 9.1-second run at 163 mph with its flagship Alpha 10 GT-R.
Since then, SP has consistently been hitting the 9.2-second mark with its SPE1000 setup, inching closer to the ever-elusive eight-second barrier.
“With the right [elevation] and a good 60-foot launch, the SPE1000 can do very high eights, we believe,” Wong said.
SP plans to debut its top-of-the-line Godzilla package on track in the next month in another attempt to break the eight-second barrier. Piloting the SP Godzilla GT-R will be longtime customer and hot shoe Hing Yim.
If you have deep enough pockets and a strong stomach, you can have your own Godzilla GT-R for just less than $100,000. More than 20 kits have been ordered". (update: the current record is 9.05 @ 166)
