Switzer Nissan GT-R Super Silver

April 9th, 2010 No comments

When Nissan introduced the latest R35 version of its GTR Skyline models, the marketing push behind the car put a heavy emphasis on Nurburgring times and the amazing techno-wizardry that led to the new GTRs phenomenal on-track performance.

Despite setting the expectation bar high, the cars didn’t disappoint their new owners on the track – but as their comfort levels with the GTR grew, some of the GTR’s new owners started to realize something that Lotus buyers had known for years: on a racetrack, mass is the enemy.

Mass affects the way a car stops, turns, and accelerates. Less mass is good. Less mass means a driver can get more grip in the corners, more stopping power from the brakes, and – with a superior power/weight ratio – more miles per hour in the straights. More mass, however, is bad. More mass means the tires get overworked, the brakes fade early, and – with more pounds to motivate – fewer miles per hour in the straights. Even fuel economy suffers!

At a portly 3800 lbs., even the most die-hard Skyline fans admit that the R35 GTR has a lot of mass to carry around a track – which motivated one New England GTR owner to contact Ohio-based tuning firm Switzer Performance, and see what Tym Switzer and his crew could do to help Godzilla zig.

“The client had some pretty clear goals with this car.” explains Tym, “This GTR couldn’t be trackday special that would deafen you out on public roads. The client was looking for a car that he and his wife could drive out 2 or 3 hours to the track in reasonable comfort, fill it up with pump gas, set killer times lap after lap after lap, and drive to a nice dinner afterwards without issue. Basically, it’s a race car with climate and cruise controls, and that’s kind of a lot to ask!”

The Switzer crew set to work on the Super Silver 2010 GTR, starting with the company’s proven P800 kit, which replaces the car’s intercoolers, intakes, and turbochargers with Switzer components that bump the GTR-engine to 800 hp and almost 700 lb-ft of torque … but didn’t stop there. “Adding 300 more horsepower the car obviously helped its power-to-weight,” Tym adds, “but more importantly none of the components in our P800 package and our new cooling package, which this car also has, are any heavier than stock. When we built the kit originally we didn’t want to make the car any heavier than it already was, and with this car in particular we wanted to reduce the weight as much as we could, without sacrificing the ‘GT’ aspect of the GTR.”

To that end, Switzer fitted featherweight carbon rotors from AP, which cut a significant amount of unsprung weight (the enemy of handling) and rotating mass (the enemy of acceleration) from each corner of the GTR, while improving fade resistance. Application-specific pads, high-temperature brake fluid (AP), and stainless steel braided brake lines round out the brake package with improved pedal feel and increase stopping power.

Weight was also cut with the addition of a lightweight (ceramic-coated) titanium exhaust system, dry-carbon decklid, and lightweight sports seats from Bride. “We chose these seats because of their adjustability. You can be comfortable, still get to the back seat, and it’s not an extreme one-piece seat that’s not comfortable on the highway. They fit the project goal perfectly.”

Up on the scales, this weekend warrior weighed in at a much-improved 3600 lbs, which is enough to make a significant impact on handling, braking, and straight-line speed.

Further enhancing handling is a fully-adjustable JRZ suspension system, complemented by stiffer adjustable swaybars, an underbody diffuser, and an active-aero wing from Aeromotions, which supplements braking and cornering by constantly varying the wing’s angle of attack.

“This car is really an amazing collaborative effort,” offers Tym. “Everyone involved really came through on this build, and the data we got from JRZ and the brake guys at Stillen who import the AP rotors helped us tie it all together into a coherent package that is at home on the track and in town, too. All we need to do now is get it on the track with the client behind the wheel, and dial it in to his driving style – that’s what’s really important here, that we get it right for him and deliver the ‘track animal’ he ordered. Once he’s comfortable in the car, we’ve got a list of GTR ‘track records’ that we’d like to beat. I think this is the car to do it.”

Switzer’s P800 and upgraded cooling packages are available through Switzer dealers. Contact Switzer Performance for more information.

COBB Tuning Takes On Time Attack In 2010

February 25th, 2010 No comments

COBB Tuning is officially throwing its hat into the ring and announcing its participation in the 2010 Redline Time Attack series in a big way. COBB Tuning Motorsports will field a three car racing team participating in the Modified, Street Tire and Enthusiast classes for the full 2010 season. In addition, COBB Tuning has assumed the title sponsorship of the Modified Class for 2010. The newly formed COBB Tuning Motorsports division will prepare and campaign the race cars from its facility in Scotts Valley, CA.

The COBB Tuning Redline Time Attack team will be attending all ten events on the 2010 schedule to compete for the championship in each of the three classes it is participating in. Pro driver Brian Lock will be piloting the 2010 COBB Tuning Nissan GT-R and taking on the COBB Tuning Modified class. SCCA Regional wheel-man Cameron Benner will drive the 2006 COBB Tuning Subaru STI and battle it out in the Street Tire class. Novice driver and owner of COBB Tuning, Trey Cobb, will be driving the COBB Tuning “Mystery Machine”, to be announced at the first round of the series, in the Enthusiast class.

The COBB Tuning Time Attack team will be staffed entirely by COBB Tuning employees. Tim Bailey, Senior R&D Tuner at COBB Tuning, will be responsible for the team’s multiple engine programs. Steve Lock of COBB Tuning Motorsports will keep things running like clockwork as the team’s Crew Chief. Head technicians from the COBB Tuning Surgeline and COBB Tuning Plano facilities will fill the roles as Car Chiefs for each race car. Employees from engineering, customer support, marketing, sales, research and development and fabrication will rotate through positions in the team with the goal of developing new skills and knowledge that will ultimately improve COBB Tuning products and further strengthen COBB Tuning as a company.

“Everyone at COBB Tuning is fired up about our return to racing”, said Gary Sheehan, Director of Marketing. “Our company is made up of auto enthusiasts that love power, speed and competition! We are putting a lot of effort into Redline Time Attack this year as we think it is THE place to show off our passion as tuners, fabricators and racers. We are really looking forward to meeting up and spending time with fellow enthusiasts at these exciting events all over the country.”

The Redline Time Attack is one of the fastest growing forms of motorsports in the US. The Time Attack racing format is styled after qualifying sessions, pitting each competitor against the stopwatch, demanding maximum performance from driver and race car alike, in just three timed laps per session. Vehicles are classed according to levels of modification, and further differentiated by driveline type (AWD, RWD & FWD). Redline Time Attack is unique in that all driver experience levels are represented at the same event, from top-level famous professional racers to novice drivers just getting started in their development. It is one of the few venues where racing spectators can also be racing competitors.

The Redline Time Attack series has undergone significant changes during the off-season and is poised to be the motorsports focal point for auto enthusiasts in the US. Ten events will take the racing teams crisscrossing across the country from coast to coast. Time Attack mainstays such as Buttonwillow Raceway Park, Willow Springs International Raceway and Auto Club Speedway will be joined by premier race tracks new to the series, including Sebring International Raceway and Infineon Raceway.

New tracks mean new track records, and COBB Tuning is anxious to stake their claim and lay down the fastest lap in class at each of the new locations. Be sure to attend a Redline Time Attack in your neck of the woods and spend some time with the COBB Tuning crew as we take on the best teams and drivers that the Redline Time Attack series has to offer!

SP Engineering Nissan GT-R – 816 horsepower with a slipping clutch

February 20th, 2010 No comments

We just reported that Boost Logic currently has the highest horsepower GT-R, but SP Engineering isn’t far behind. Boost Logic made a very impressive 823 wheel horsepower, but SP Engineering made 816 wheel horsepower, and 770 ft lbs of torque. SP Engineering could have surpassed the 823 made by Boost Logic, but they had problems with a slipping clutch.

According to SP Engineering:

At 1.7 BAR, we’ve reached 816 ALL wheel hp / 770 Torque from a baseline of 395-400. As our previous setup 4-5 months back we’ve accomplished 780 All wheel hp on Q16. This proves the Greddy turbo kit produces great numbers from 3500 RPM at 360 AWHP, 4000 RPM at 520 AWHP and so on. Massive turbo response and power all the way up to 850 awhp is what you will receive from this kit. With the help of aftermarket cams, stroker kit, etc, power levels will definitelly be greater.

We wouldn’t leave you without a video of this beast, so check it out:

Here is a dyno graph of this run:

Engine Modifications:

Greddy Twin Turbo Kit
Greddy Intercooler
CP Pistons With Coating (Standard Size)
Carrillo Rods
1000cc Injectors
SP Engineering Custom Dual Fuel Pump 255 LPH + FPR
Titek titanium race mid pipe
Titek titanium race exhaust
Haltech ECU
