I'm quoting directly from the factory sales brochure. I'll give some more direct quotes
"Since its introduction, the race bred 911 Turbo has stood alone as the fastest, most powerful production Porsche ever built. But now, turn your attention to the new 928 S4. Like the 911 Turbo, the 928 S4 started life as a breakthrough in sports car design, promising a new level of performance. Different from the challenge of the 911 Turbo, yet everybit as rewarding. Incorporating the most advanc ed technology our engineers could devise, the 928 S4 stands alone as the fastest, most powerful production Porsche ever built. The ultimate expression of Professor Porsche's philosophy"
Those are direct quotes from the brochure, which also appeared as adds in Road and Track, the the performance numbers i gave come straight from the add.

Yea, lets get to part about the 5.5 second turbo. Lets face it the 928 was the fastest "NORMALLY ASPIRATED" production Porsche...no doubt... but I don't think you are going get one person in this forum to believe that a stock N/A 928 is capable of taking on a "Forced Induction" 911 Turbo and hope to win (in any year) that is simply insane.

The 911 Turbo's in those years had almost 400 ponies and weighted in lighter than your manual shift 928S4 or GTS.

Fastest is not necessarily the quickest ! and quickest not necessarily the fastest. Most powerful is often not quick or fast.......think freight train

I get 3031 lbs for the '99 Carrera, which is a heck of a lot lighter than a 928. That's from the Autotrader site, under model info. They quote the '87 928 as weighing 3351 - 320 lbs more. That works out to 10.6lbs/hp for the 928 v. 10.2lbs/hp for the 996. The 928 needs to lose 130 lbs, or gain about 20 hp. Or both

it's air-cooled?

At least we're comparing Porsches to Porsches here. I'm sure glad we're not getting into why most new Hondas and Toyotas can beat 928 's in a straight line these days. Forget magazine numbers. Just dare to race a ricer from the light. I've had my a$$ handed to me enough times to never do it again...unless boosted

Very interesting post to me since my brother owned a 930 at the same time I purchased my 88 model 928. I can state we are not race car drivers but the 930 NEVER was faster at top speed or on freeway exits. It was always faster to 75 if he didn't miss a shift. I think that by just flooring the auto 928 I could beat him 3 times out of ten when he would have an excuse for his limited shifting ability.

That's cause the 'ol 930 turbo, in 1987-89 vintage had less than 300 HP. Look at the spec - i think it was 288HP. I had an '88.

HA HA HA!! I'm glad someone said it. Its getting old trying to explain the whole "faster through the twisties" thing to riders.

The 1979 Porsche 930 was a 3.3 liter, intercooled, turbocharged monster that could go from 0-60 in 4.9 seconds, and allow the speedo needle to soar past the 165 mark. It was also the last year for the 930 that was then just titled "Turbo" on the rear deck lid. The 930 was discontinued in the US due mainly to emissions requirements.

After its 7 year absence, the Turbo finally returned in 1986. It was virtually the same model, sporting the 4 speed gearbox and a very nervous rear end. Yet by 1989, the car had a 5 speed box, 285 horsepower, a better suspension, better brakes, and wider tires. Performance was down from the Euro version due to strict emissions laws. It was unfortunately slower than the 1978-79 model.

The 1991 911 Turbo (No longer designated type 930), was a 911 rolling on the 964 chassis, but with a 3.3 liter engine, instead of the 3.6 of the Carrera. They worked wonders with the exhaust system, and even with all the required emissions crap, the '91 Turbo arrived as the fastest and safest 911 yet.

Each year, when the 911 Turbo was thought to be at its peak is was learned that it was not so, because for 1993, the engine size was increased to 3.6 liters, and more power, more speed, and better handling was set forth. It now had 360 horsepower and 383 lb-ft torque. It had dual exhaust, better brakes (how???), and totally redone engine components. The 911 Turbo 3.6, as it was called then, showed the world how much Porsche could improve on something already thought to be perfect.

The Turbo 3.6 led the way for 2 years, and was discontinued by 1995 (Same year as the Porsche 928GTS). At Geneva in 1995, Porsche introduced the 1996 911 Turbo. It had the updated 993 body style with flared fenders and a new, melted-look whaletail. The engine was of 993 variety, but this time with twin turbochargers!

Hey doublenutz thanks for the history. That's what i was looking for. I recall my Turbo being very fast for even having 285 HP. And the 4 speed was a bitch but boy did that car get looks. I'm still lusting after a twin turbo...
