Oh, and number four might be the greatest one. :D

thats great... just completely awesome

The Porsche flat six is a great engine. I didn't know it had seven oil pumps. I wonder why? I would have thrown the Audi 6.0L V12 TDI Diesel in there. I know it's a diesel, but the thing makes 500hp and 740 lb ft of torque. And since it's a diesel that torque is available throughout almost the entire rev range. The thing sounds great as well and still gets 20mpg with all that power.

I seriously lol'd when I read that one line. :lmfao:

Some sound clips would've been VERY nice.. lol, its kinda hard to imagine some of the sounds they attempted to convey especially when what you actually hear is nothing like what you could imagine in your head.

No matter which way the weight shifts, there will always be oil pressure.

Carbon blower rotors look cool.

Just go to youtube and search any of the cars they listed.

I thought that was the reason for dry sump systems. Is there some characteristic of the flat six that makes even a dry sump system inadequate? You have Ferrari's, Zondas, and Corvettes that achieve higher g loads and don't require 7 oil pumps. I also wonder if these things work independently or in series.

I need to visit a Porsche forum because this has me curious.

This is some info a found with a quick search on how they work, but this suggest there are only 3 pumps.

Dry sump lubrication from and for racing
Given the exceedingly high-performance intent of the 911 GT3 and GT3 RS, every element of the cars must withstand extended periods of high levels of lateral acceleration. Drawing from decades of racing success, Porsche engineers ensured the cars' engines would always be adequately lubricated, even under the most extreme driving conditions.

This is guaranteed by integrated dry sump lubrication incorporating two re-delivery pumps and a pressure pump. The lubricant is cooled by an oil/water heat exchanger.

The three-element oil pump is driven by the crankshaft via a layshaft and a connecting shaft. A pressure pump supplies pressurized oil to the engine's lubricating points. This supply pump extracts engine oil from a separate oil tank, sending the oil through an oil/water heat exchanger and oil filter before continuing into the engine oil circuit. The other two pump segments draw out the oil accumulating in the crankcase and pump it back to the oil tank.

The integrated dry-sump system is so precise at monitoring oil levels that the engines have no engine oil dipstick. Instead, an electronic monitor measures the oil level and displays the result on the instrument cluster.
