Switzer R850 Nissan GTR gets a shot of race gas [Video]

Tym Switzer's Oberlin-Ohio based tuning shop has been a breeding-ground for pump-gas monsters this year, including the 800 hp Nissan P800 GTR. Of course, as soon as Switzer's customers got their hands on the cars, they started asking for more.

"How much will it make on race gas? That was the first question, right out of the box," explains Tym. "I explained that we'd developed the "P" packages as daily-use products that wouldn't force you to buy race gas or excessively strain the driveline. We wanted to make an 800 hp car that was a true daily driver, and we accomplished that ... but someone always wants more. We've bent a bit to the demands of those customers that are using their GTRs primarily as trackday cars, and developed a new 'R' package specifically for them."

The "R", in this case, refers to race fuel - as the "P" in "P800" referred to the fact that the package was developed for "pump gas" - and with better fuel comes, of course, more boost, and more power. "We're seeing consistent dyno results in excess of 740 all-wheel-horsepower and 715 lb-ft, pull after pull. Most everyone seems to agree that the GTR has about a 15% driveline loss. Based on that, this kit is making well over 850 hp and 820 lb-ft at the crank."

Pricing for the new R850 package from Switzer is set at $20,990, which includes pump gas and race fuel tunes, as well as Switzer's updated cooling package, featuring a massive dual-core radiator, thermostat, and revised Switzer MONSTER intercoolers.
