The air-cooled Porsche 911s with dry sump lubrication were equipped with a larger volume of motor oil compared to the water-cooled variants. The air-cooled models typically had a total oil capacity of around 10-12 quarts, while the water-cooled versions had a smaller oil capacity of around 8-9 quarts. This larger oil capacity in the air-cooled models helped to ensure better cooling and lubrication for the engine, especially during high-performance driving. **

Dry sump lubrication is advantageous for lowered cars because it eliminates the need for an oil pan, which is typically the lowest point of the engine and susceptible to damage from speed bumps, potholes, or other road hazards. By removing the oil pan, the risk of it being damaged is significantly reduced, allowing lowered cars to navigate uneven roads without worrying about oil pan damage. Additionally, dry sump systems provide better oil control and lubrication efficiency, which can be beneficial for high-performance engines often found in lowered cars. **

A substitute for dry shampoo could be baby powder or cornstarch. These powders can help absorb excess oil from the hair and give it a fresher appearance. Simply sprinkle a small amount onto the roots of your hair, massage it in, and then brush it out to remove any excess powder. This can help extend the time between washes and keep your hair looking fresh. **

One substitute for dry shampoo is baby powder or cornstarch. Simply sprinkle a small amount onto your roots, let it sit for a few minutes, and then brush it out. Another option is to use a DIY mixture of arrowroot powder and cocoa powder, which can help absorb excess oil and add a bit of color to match your hair. Additionally, you can try using a volumizing powder or a texturizing spray to help refresh your hair between washes. **

An alternative to dry cleaning is using at-home fabric care methods such as hand washing, spot cleaning, or using a gentle laundry detergent in the washing machine on a delicate cycle. Another option is to seek out professional wet cleaning services, which use water-based solutions and specialized equipment to clean delicate garments without the use of harsh chemicals. Additionally, some fabrics can be refreshed by steaming or airing them out in a well-ventilated area. **

No, dry shampoo is not an alternative to deodorant. Dry shampoo is used to absorb oil and refresh the hair between washes, while deodorant is used to control body odor. They serve different purposes and are not interchangeable. It is important to use both products as intended for proper hygiene and grooming. **

A substitute for dry shampoo made from flour can be a mixture of cornstarch and baking soda. Simply combine equal parts of cornstarch and baking soda, and then apply it to your roots and massage it in to absorb excess oil. This homemade dry shampoo alternative can help freshen up your hair in between washes and give it a clean, refreshed look. **

The exact purpose of a dry sump lubrication system in the automotive sector is to provide a more efficient and reliable way of lubricating the engine. It uses an external reservoir to store the oil, which allows for better oil control, reduced oil starvation during high-speed cornering, and improved engine cooling. Air-cooled Porsches, such as the 911, did not have a dry sump lubrication system in the traditional sense. Instead, they used a "dry sump-like" system where the oil was stored in a separate tank, but it was not a true dry sump system. Today, water-cooled Porsches, such as the 911 Carrera, do use a dry sump lubrication system. This allows for better engine performance and reliability, especially during high-performance driving. **
