i know its been a while, but great to hear :)
HIROSHIMA, Japan — Sources close to Mazda told Inside Line today that the next Mazda RX-7 is still in the works. Inside Line has also learned that a new Mazda RX-8 is also in the works and is expected to be called the Mazda RX-9.

Mazda will not let the rotary engine die with the current RX-8, sources tell IL. The company is well along in development of its next-generation RX-7, fitted with a front midship-mounted 16X rotary engine. The engine will generate upward of 270 horsepower from a normally aspirated power unit, they say.

The new twin-rotor engine will feature an 800cc x 2 configuration, up from the current 13B's 654cc x 2 format, while improving fuel economy by 20 percent.

By building such an engine, Mazda is looking to clean up a rotary image that was fraught with poor economy and emissions and excessive oil use.

The next RX-7's transmission is also all new. It's a twin-clutch, two-pedal six-speed unit with a twist that allows drivers to set the revs at which the clutches engage.

Engineers are also reportedly working on weight issues. By developing a new chassis, they have been able to shed some 220 pounds, reducing the RX-7's curb weight to the 2,640-pound range, according to one source.

Info: The BLITZ 'Sus' Power air filters are made from T304 stainless steel which is totally unique to Blitz. The entire filtration element is made from a fine stainless steel mesh which means the filters never wear out and Blitz claim they have substantially less restriction than any other filter. Some of the other aftermarket filters are made from paper or foam elements, and some do require oiling to maintain their filtration capacity. According to Blitz, this oil gradually disperses into the inlet tracts of an engine, and coats the walls and in particular the air flow sensor, slowly reducing the performance of the vehicle. The Blitz air filters also have the same fine mesh in the top of the filter, which improves the amount of air they can flow, and because the element is 100% metallic.



Info: HKS state that engine power is directly related to the amount of air an engine can take in and expel. Therefore, one of the easiest and least expensive ways to increase the horsepower of any engine is to improve the airflow into the cylinders. However, many products in the marketplace sacrifice air filtration capability for improved air flow characteristics. HKS claim that their High Performance Air Filter Systems offer the ultimate in both air filtration and air flow for maximum engine performance. The elements use a special oil to stop unwanted dirt particles from passing through the multi-layer polyurethane filter. Filters are thrown away when their lifetime has expired and are replaced with new filters, which are inexpensive and easy to replace.




Info: K & N use their own unique design unlike others which use a conventional paper or foam material. K & N state that because the dirt particles are trapped inside the passages of foam or paper filters, that they eventually clog, and when this occurs, airflow restriction increases dramatically. The K & N filtercharger uses a special cotton fabric which is sandwiched between aluminum screen wires. K & N claim that the pleated design provides five times more filtering surface over the element circumference. The filter is then saturated with an air filter oil which attracts particles of dirt and debris which build up on the outside of the filter.
