		<description><![CDATA[Tweet In 1986, Toyota released a supercharger car based on the stellar 4age motor found in the corolla. The MR2 with its mid engine rear wheel drive platform was a great everyman&#8217;s supercar and was powered by the 4agze supercharged motor&#8230;  Now, everybody’s heard of unicorns, these mythical creatures that somewhat similar to horses, but possess more beauty and more power with their visually distinctive uni-horn. However, nobody’s ever seen a unicorn. Some of us may even begin to doubt that this mysterious creature every existed. The same goes for the 7AGZE engine. Almost everyone I know who’s interested in Toyota has either heard of it, thought of it (and thought it was original), or thought of actually trying it? But to date, very few people have seen it. The 7agze is a hybrid engine of: 4age:  a 1.6 liter rev happy engine first introduced in rear wheel drive corollas. Coupled with a 5 speed manual , a Front/Rear drivetrain configuration, and a very light chassis (no airbags, no crumple zones, no sound deadening, no seat massagers, no nonsense) made for a fun commuter car that later became a drifter’s modern classic. 7afe: a 1.8 litre stroker version of the [...]

		<description><![CDATA[Tweet Positive displacement superchargers do not usually compress air inside the supercharger but rather better described as air pumps. Positive displacement superchargers are usually rated in liters or cubic inches (or a similar measure of displacement). The reason behind that is that a 1.5L rated positive displacement supercharger moves 1.5 liters of air per revolution and so to produce 15psi of boost (or a pressure ratio of 2.0) on a 1.5 liter engine, the supercharger would have to be geared to double the rotating speed of the engine. Thus for every round of the engine, the engine would normally ingest 1.5 liters of air, at the same time for every round of the engine, the supercharger completes two full rotations because of the gearing between the engine crank and the supercharger, and thus the supercharger puts out 3.0 liters of air for every 1 revolution of the engine. The result is that the supercharger pumping and feeding 3.0 liters of air to a 1.5 liter engine, which results in the air being compressed inside the intake manifold between the cylinder and the supercharger, and effectively forcing the engine to breathe twice as much air, simulating a motor that is twice [...]
