Yes, tips sap horsepower. Jake and I did a back to back test - we pulled the 2.5 from my 99 tip which dynoed at 163 at the rear wheels then did the same engine in his manual, it was well over 180 hp at the rear wheels. He posted on rennlist a graph of the two compared, it was shocking to say the least. We didn't even change the oil in the engine between comparisons! I had been told years ago that a slushbox ate about an additional 8-10%, but from our test it's as much as 14% on top of the typical 20% loss figured between flywheel hp and at the rear wheels on a manual. Just food for thought.

The PDK is awesome. Having owned several cars with VW's DSG and driven other sequential manual gearboxes, if I could figure out how to shoehorn a PDK in my 99, I would do it in a heartbeat.

When, in the driving I do, will I ever ask for more than 60% of the capability of the car? The only case I can think of is a freeway merge and maybe a passing situation and I already have way more power than all the Priuses that pass me.

I'm of the opinion my '99 2.5 TIP was more fun than my '01S 3.2 TIP because it didn't have as much power and you got to drive it harder for longer in more situations.

who is going to go out and drive his slow slushbox for the first time in 4 weeks (medical) and enjoy the heck out of it.

Well in monetary form that is about $1,700 dollars in aftermarket power adders!

I have a 2000 S tip. Too good a deal to pass up and extremely low mileage.
It had the color and options I wanted. But...it was a tip. I drove it and loved it right away. Bought it and couldn't be happier. I think I've driven it twice in full auto mode, as it's alot of fun to shift manually.
Each to his own they say...

+1 on loving a Box with a Tip. It's a great driver. While I do think that shifting a manual is major fun, I really wouldn't trade my Tip for anything.

LB nailed it. I drive a 5 spd but would have bought a tip if in the right car. A modern tip trans is so good (PDK is incredible) that the old manual trans seems like a bit of a dinosaur on a modern Porsche.

Yes the manual trans will reveal more RWHP on a dyno. Yes a well driven tip will often turn faster laps on a track. Drive what suits you best. My next Porsche will have PDK.
