corn-fed godzilla




NOW AVAILABLE IN STORMTROOPER WHITE AND CORNHUSKER YELLOW


When Nissan introduced the latest R35 version of its GTR in 2008, the international press was quick to nickname the car “Godzilla” - as much for the car’s size as for its fire-breathing performance - and Nissan was equally quick to call the car both “perfect” and “untunable”. That “perfect” label is a matter of opinion, of course, but enough GTR buyers felt the car lacked sufficient oomph that a number of tuning firms began to lay waste to the idea of an “untunable” car, building massively-powerful GTR Nissans along the way. One such firm is Tym Switzer’s Ohio-based Switzer Performance, and their massively-powerful GTR is called the P800 - a comprehensively tuned 800 hp track-weapon that’s as much at home on Main Street as it is on the back straight.

Of course, there are some enthusiasts who will always want more - and when one of these enthusiasts contacted Switzer about pushing the P800 GTR to the limit, the crew at Switzer Performance got to work developing the car you see here.





SEEMS ZIPPY ENOUGH


“The P800 is already at the limit of what we feel comfortable for the stock GTR transmission,” explains Switzer. “So to go further we really needed to beef up the transmission. We contacted Dodson Motorsports in New Zealand and explained what our goals were with the car - 900 hp, more clutch area, ad smooth shifting at every speed. The new transmission is the product of several months’ co-development between Switzer and Dodson, and is exactly what we needed in order to start pushing the GTR forward beyond 800 hp.”

The next thing Switzer needed to address to keep “pushing the GTR forward” was fuel. “We didn’t want to just deliver a race-gas package that tethered the client to a fuel drum in his garage, but we wanted to be able to turn up the boost, also.” The solution? Readily-available E85.

“In a way, the solution was all around us,” offers Switzer, whose shop is located deep in Ohio’s farm country, surrounded - literally! - by cornfields. “E85 isn’t without its trade-offs. We had to modify the fuel system to handle the fuel and significantly increase the size of the injectors, also, but in the end we had a fuel that gave us everything we needed to crank up the boost on this car and deliver over 900 hp.” The E85 delivered other benefits as well: it is significantly “greener” than the pump-gas and race-gas versions of the GTR. “With most high-horsepower cars, you can barely breathe after just a few dyno runs. With the E85, we were able to run pull after pull to dial in the tune without feeling any effects of the usual emissions. It’s hardly scientific, but there was a noticeable improvement in the air quality in the shop compared to race gas.”

The final product - dubbed the E900 for “Ethanol fuel, 900 hp” - is a fast, capable package that offers linear power delivery and massive midrange torque with superior transient response compared to larger-turbo/race-fuel combinations, while maintaining a bit of environmental responsibility along with its blistering sub-6-second 60-130 mph acceleration.



GREEN AND MEAN


This first E900 also sports an Amuse carbon fiber aero package, 3-way adjustable suspension, and 20” BBS wheels that are an inch wider than stock at all four corners. Switzer’s new E85-fueled E900 PKG is available now. Contact Switzer Performance for more.

It's been quite a while since I last posted anything on the Gas 2.0 site, and I can't honestly tell you which of my many excuses was truly to blame for this. Regardless, I'm back there, too!

More me is always a good thing, I think. Click the pic above to read up on Dyno-Comp's new high-boost E85 STi demon package, Rich and co. did a great job!


Thanks for the tip, Shane!

renntech announces green racing engine






Lake Park, FL - 15JAN2008 - RENNTECH's New Year Resolution: Greener Engines.

After closing out 2007 with exciting news about the SLR McLaren 722GT and Jamie Ferrell's big Open-class victory at December's Tulsa Shootout, the Mercedes-Benz super-tuning firm RENNTECH is kicking-off 2008 with some environmentally responsible resolutions, starting with the XR50 rotary kart engine.

"When the XR50 was at the Tulsa Shootout, which was the engine's first national-level race, many people were asking why we were building a rotary to begin with," explains Hartmut Feyhl, RENNTECH's president and former AMG technical director. "Development on the motor first began in 1996, with Paul Woelfle in Germany, who built the motor as a response to tightening emissions regulations in Europe. The goal was to have an engine that was competitive, but with much cleaner exhaust than the 2-strokers. We accomplished that, and the engine is now as clean as the very best 4-stroker kart engines - but we felt we could still do better, and that led to the E85 version."

Shown here in an "Eco Green" paint scheme (production models remain "RENNTECH Red") the modified RENNTECH /Aixro XR50 offers environmentally conscious racers something really unique: a cleaner, flex-fuel karting engine that can run away from the "dirty 2-strokers" that have, until now, dominated the sport. "On most track configurations the Aixro is superior, which is what you would expect from a motor with almost 50 hp," offers Feyhl.

You read that right: almost 50hp. In a 285 lb. sprint kart (weight with driver) the RENNTECH /Aixro XR50 delivers a power-to-weight ratio better than a Corvette, Porsche 911 or Ferrari F430, so buyers can expect to experience 100 mph at 2" from the ground (!).

"2008 is really going to be a big year for RENNTECH," says Feyhl. "We will be announcing a few other projects soon, and a good number of them will have a 'green' angle. This is something that all tuners will eventually be doing, even though many are still fighting it. We think it's a very exciting time to be developing new products, and have been very excited by the potential of some of the new technologies."

E85 Aixro rotaries will be available in Feb., MSRP for the XR50 is $5250. Contact RENNTECH KARTING for more information.
