 Switzer P800 now available for Tiptronic Turbos, 0-60 mph in 2.8 seconds
Switzer P800 package for Porsche 911 Turbo Tiptronic 08.07.2010

Ohio-based engineers at Switzer Performance have released a new version of their P800 kit capable of working with the 997 Turbo's Tiptronic transmission.  The transmission, normally only capable of handling up to 700 horsepower (522 kW), was totally rebuilt and modified to handle more power.

"When we released our P800 kit for the 997 Turbos, which makes over 800 horsepower (597 kW), we were forced to limit sales to manual-transmission cars," said company chief Tym Switzer in a press release.  "This didn't satisfy the customers who wanted the kind of ultimate straight-line performance that the Tiptronic can offer, and, to be frank, it didn't satisfy us."

For the project, they added more friction surfaces to improve power delivery, improved shift speed with a new valve body, eliminated transmission slips with more clutches, and reprogrammed the entire transmission control unit software.  The result is a Tiptronic 997 Turbo that sprints from 0 to 60 mph in 2.8 seconds, even when using standard air pressure, tires, and fuel.

Final calibrations are still being made to the package.  The transmission itself could wind up on other Porsche tuner models as well, with Switzer believing that TechArt and 9ff may have an interest in the project.

The cost of the transmission on its own will be $7,990.


OBERLIN, OH - 06JUL2010 - Tuners everywhere rejoiced when Porsche introduced an upgraded Tiptronic transmission with its 997 Turbo models. The five-speed automatic/manual, built for Porsche by German neighbors Mercedes-Benz, is capable of handling as much as seven hundred horsepower in some applications ... and, for most tuners, that's all the capacity they will ever need.

For Ohio-based Switzer Performance, however, 700 is far from enough. "We first noticed the limitations of the 997 Tiptronic with our P700 (l4) PKG, which, pushed hard on certain high-octane fuels, can cause slipping in the trans.," explains Tym Switzer, owner and chief engineer of Switzer Performance. "When we released our P800 kit for the 997 Turbos, which makes over eight hundred horsepower, we were forced to limit sales to manual-transmission cars. This didn't satisfy the customers who wanted the kind of ultimate straight-line performance that the Tiptronic can offer, and - to be frank - it didn't satisfy us."

After spending a considerable amount of time reprogramming Porsche's transmission control unit (TCU) software to increase the torque limits, Switzer realized that effectively putting more than seven hundred horsepower through the Tip cars would require something more than a software-based solution.

Working with development partners in the US and Europe, Switzer disassembled, upgraded, and rebuilt the Tiptronic transmission to meet customer demands for higher hp projects. The first builds produced transmissions that were stronger and sharper than the factory unit, but not strong enough to contain Tym's hard-hitting P800. This final effort, however, Switzer and his European counterparts pulled out all the stops: additional clutches eliminate slippage, additional friction surfaces ensure more efficient power delivery, a modified valve body to improve shift speed, and (last, but not least) another round of transmission programming which enables the Tiptronic to make the most of its uprated internals.

On its maiden voyage, the new 997 Turbo P800 Tiptronic blasted from 0-60 mph in a scant 2.8 seconds. On standard tires. With standard air pressure. On pump gas.

Subsequent tests confirm that Switzer had produced one of the quickest daily-driver Porsches in history - and Tym isn't shy about using the "B-word" in discussing the car's performance, either. "These cars have Bugatti performance from 0-60. We're still perfecting the calibrations, but we expect our clients will go Veyron hunting very soon, and those guys don't like to lose."

Switzer is in no hurry to share the precise secrets of building nine-hundred-horse-capable Tiptronic transmissions, but the company is perfectly willing to build up transmissions for owners of other tuner cars, as well. "Of course, I have to believe that our P800 kit continues to be the ideal daily-driver/trackday package, but some clients have a comfortable working relationship with TechArt or 9ff. They still want a quicker Tiptronic car that they can turn up the boost on, though, and we can work with them to make that happen, and help them get the most out of the investment they've already made" says Switzer.

Drivers who participate in 0-100 or 1/8 mile dragstrip challenges may find Switzer P800 Tiptronic to be the perfect weapon; with the PCCB ceramic brakes and the 911's traditionally brake-friendly weight distribution, 0-100-0 supremacy is all but assured.

Switzer's transmission upgrades start at 7990 USD, but anyone who wants to hit a hundred miles per hour before the most supercars make their way to sixty may consider it money well spent.

Now here is a reason why we shouldn't waste money on a bugatti.

It tops out at 253mph? I didn't realise that...

So I'm guessing that this will probably do 0-62 in 3.0 or 3.1 secs? That's been done before many times in a Porsche. My other question would be, how often can this tuned 911 hit these figures before it blows up.

it says 2.8 !!! not 3.0 or 3.1 obvious some GTR fan...

No actually I'm a huge Porsche fan. I just get annoyed with tuning companies claiming numbers from 0-60 rather than 0-62.

Who cares lol? Its like the same thing. Oh yeah and FIY, Turbo 911's can take boost pretty good unless 9ff gets its hands on it so no worries of a blowup. Oh yeah and that isn't even a bad deal for a transmission like that.

@Dragos I take it you live in an area where performance figures are based on 1-100km/h are readily used? Well...Switzer is an American firm so 0-60mph would be what these guys deal with 99.9% of their time. It has to be understood... Usually the two figures are nomially close though aren't they?

LOL! Believe it or not, I enjoy your comments. You are right, we should post 0-100, 0-200 times, etc. along with 0-60. As for blowing up, the P800 is a mild tune for us, built to run safely and effectively at 800 hp on 93 octane pump gas. In all our packages, "P" stands for "Pump fuel", and designates "daily driver" status ... the R911, for example, is a 900+ hp car on "Race" fuel (109 octane or better). Sometimes you will see P800/E900, which indicates power levels at pump and ethanol, etc.

So Switzer is having it's own GT-R v 911 Turbo war? Will there be an ethanol-powered 900PS 997 Turbo P900 soon?

YES!! The office is actually split between "GTR" guys and "Porsche" guys pretty evenly.

this is the older version , i wonder what they can do with the new 997.2 turbo S with PDK.

The new version (PDK) is a much lesser car than the 997.1. The 996 tt and 997.1 tt were based on the old GT1 engine program, and the case, pistons, rods, etc. could take ENORMOUS pressures before being stressed to a breaking point ... we have several 1000 hp cars to prove this. The new 997.2 motor uses some software tricks to get the most of the power it is making, and is essentially a blown version of the "corporate" flat 6 used in the Boxster and C2 ... nowhere near the durability of the 997.1 ... these power levels aren't feasible on the 997.2 for this reason.

thanks for the link, Jo. i know about the GT1 engine, but i didn't know it was that tough. i thought the new direct injection engine with the faster gearbox would have more potential. this explains why Porsche used the old 3.6 engine on the new GT2 RS.

and you jale want to represent Porsche fanboy and you cant even see the difference between 0-60 and 0-62? pathetic

i don't want represent anyone, and don't even like porsche or nissan just reading some posts and cannot believe that poeple say stupid things like making things look bad if they hate some car...and outside the US, measure acceleration from 0-100 km. 100 km is roughly equal to 62 mph. It's easier to convert 100km to 62mph so that's the way some report it...btw i didn't answer and that doesn't mean is don't know the answer, you are also OFFTOPIC! -with correction of 62mph or 100km/h again you got the same numbers because it is difference just a fcking 3km/h

Can your new gearbox, which I know is built for the the tt be adapted to other NA tip models? I have a Cayman S looking for a better gearbox.
