1999Porsche911 may get a little contentious in his posts, but I'm no more sceptical of his results than anyone elses. Once you've added a forced induction system, getting further power out of the engine is perfectly doable. Let's say he's bumped it up to 500 hp (flywheel), with a decent torque curve. Combine that with lighter weight, and less loss than the AWD system on the Turbo, and slightly increased lag on the X50 due to larger turbos, and I could easily believe that he'd walk away from any non-modified Turbo.

Engine longevity is a separate question, but it's his car, and if it blows, it blows, and I'm sure he knew that going in. Anyone with a modded car runs that risk to some extent.

I'm not saying his car performs as advertised. I've never seen it. Just saying that it's within the realm of possibility.

I recall people on other boards laughing at Chad when he started messing with his car.

If I sounded contentious, I apologize, as it was not my intention to do so.

He he. You never ticked me off. It's you bloody Midwesterners. You and ColorChange have a fairly 'assertive' writing style. I'm not complaining. If I *know* something, and people tell me what I can or can't do (as they have done w/ CC and his adventures in datalogging), I can get the same way.

Then people tell me I'm too argumentative yada yada yada.

I'm Scottish, so if arguing over the Internet doesn't work, I paint my face blue, then headbutt someone...

Funny. I am an east coast Irishman so we should get along just fine over a couple of beers.

That's 360 to the wheels right? That sucks if it's crank hp!

J. Seven - can you put some context around this? Is the text part of an official press release from Ruf, a consolidation of rumors, or something in between?

The numbers just don't add up...

Thanks

Info was sent to me from Ruf yesterday by email by their sales, marketing and public relations manager. The technical info came in PDF fomat, so this is their own tables for anyone who contact them.

I emailed Ruf to ask for the info and they sent me a Word doc. The full text of it below. The guy who emailed me said in the text of his email:
"We can perform the conversions here in Dallas (no need to pay to have technicians flown in from Germany) and the conversion kits should be available in March. Note that RUF generally underestimates hp numbers and 0-60 numbers. They prefer that the performance of their products speaks for itself."

RUF Compressor Kit for all 996 and 997 Carrera

RUF upgrades all naturally aspirated Porsche 996 and 997 Carrera for more performance.

Many Porsche 996 and 997 Carrera owners would like to have additional horsepower for their vehicles. RUF provides the solution! RUF‘s bolt on Compressor Kit, which includes a supercharger with intercooler, provides inproved acceleration, torque and maximum speed. Horsepower and torque are increased throughout the RPM range.

The compressor kit contains a centrifugal compressor, which is driven mechanically by a Poly-Rip belt. The maximum boost is 0,5 bar; the fuel preasure remains standard. The engine receives a new intake manifold, modified injectors, sports catalytic converters und a modified electronic engine management. The watercooled intercooler has a cooling water circuit with an electric water pump from the water cooler in the front spoiler.

The 3.4 liter engine has a performance of 360 bhp (265 kW) and a torque of 400 Nm; the 3.6 liter engine has 380 bhp (279 kW) and 420 Nm. The supercharged 3.8 liter engine of the 997 Carrera S provides 415 bhp (305 kW) and 440 Nm torque.

996 Carrera 3.4 liter with RUF compressor – acceleration: 0 – 62 mph (0 – 100 km/h) in
4.7 sec., 0 – 125 mph (0 – 200 km/h) in 15.8 sec. Maximum speed: 187,5 mph (300 km/h).

The Compressor Kit fits to all 996 and 997 Carrera with rear- or four wheel drive, including manual gear box or tiptronic S.

The Widebody Kit compliments the increased performance of the Compressor Kit. Included are a RUF designed front spoiler, front and rear fender flares, side skirts and a rear spoiler inspired by the „Duck Tail“ from the legendary 1973 911 Carrera RS 2.7. The Widebody Kit also fits the 996 GT 3.

While I was in Germany for factory Ruf training, I got to drive the prototype 996 compressor car for several days. The car felt way faster than the advertised HP. I asked, but, was told nothing about how much HP it actually made, other than that Ruf horses are a lot bigger than they appear. In other words they are very under rated.
As far as the 0-60 times seeming slow it is the probably due to the wheel spin the car now has due to the increase in torque. On a few occasions in Germany when no one was looking I found that it was very easy to smoke the tires at any time in first and second gear. Shhhh don't tell my bosses!
As most people that know anything about Ruf, know that they build their products for reliability first then power. Their quality and reliability is second to none.

And their's is going to be C.A.R.B. certified unlike Evo's, right?

First of all, the RUF HP numbers look correct is they are WHP. Secondly, if you had substantial traction problems with the car you test drove, it surely wasn't the increase in torque that caused it. You have only moderate torque below 4,000 rpm's anyway. You either had crappy tires on the car or the road surface sucked. I have substantially more HP and Torque than this package turns out and traction is controlable with quality tires.

We don't know yet if it has passed CARB certification. As this is a new system it takes a long time to get all of the proper paperwork and approval done. Only time will tell.

You guys should look into Turbo Performance. I had my 2004 3.6 done with them and I'm doing 405whp at 8psi. It blows away a stock turbo off the line and keeps pulling on it the entire time.

What makes the Ruf kit so much more expensive than EVO's or TPC's?

For one thing, Ruf includes an official warranty on the motor. As well, Ruf's servicie is legendary. Lastly, if they sell into California, you can rest assured they will be legal.
