[Herr-Kuhn]

People often ask about the lag on the car. The delay in onset of boost is a nice feature because it makes the car very streetable. Nobody would know they are under the hood until you roast down on it and then it's all business. I know people are skeptical of the TC vs an SC route on the 928, but until you experience the TC you don't really know what you are missing. It's somewhat alluering to be able to ride and tame the car out on the street. It still gets my heart rate up when I drive it, every time I drive it.

Here's a list of why I really like turbos:

Very quiet, takes about 1/3 the sound out of the exhuast
Civilized cruising and boost only when you want it (wife or girlfriend isn't afraid to drive with you)
Efficient turbine and compressor design...near 76% on the comprssors, more if you go larger
Compensates for altitude (run same boost at 6000 ft as you do at sea level)
Long-lasting devices
Can adjust boost from cockpit if you want to..I have not temped myself on this one yet!
Gear adjustable boost...say 6 psig in 1st and 2nd and then open it up in 3rd and above
Run 87 Octane?, then turn it down...race gas, crank it back up.
Packages well (small and hidden if you want it to be)
A ton of mid-range power and top end potential (you have to size them right to get both)

I have to give all the 928 builders/tuners credit on thier hard work. Dave Roberts, Andy Keel (one of our founding fathers), Mark Robinson, Tim Murphy (yeah, you too Schmidt), Wisconsin Todd (aka 26 psi mystery man), Dave Lomas, Carl Fausett, Marc Thomas, Louie Ott...I'm sure there are more out there too. Yes, some of us have had our differences over the years, but it is time to put this behind us and move forward in a positive manner! What has impressed me the most is the power output of the Thomas/Ott monster. He's making slightly more power than I am without any manifold pressure at all. Not that pressurizing the engine on a 928 is easy (I have in excess of 1000 hours into my development), but to make those numbers on an all-motor build is something to be very proud of. Consider if that engine was blown to one bar it would make over 1000 HP. It's mind blowing to think of the potential.
