		<description><![CDATA[Tweet The Nissan GT-R is designed to be a Porsche killer. Being the flagship of all Nissan (and currently all Japanese Supercars), it has claimed that it runs a Nurgurg Lap faster than a standard porsche 911. To add insult to this injury, tuning camp &#8220;Power Enterprise&#8221; has embraced this new beast and twincharged it. Wait! I stand corrected &#8230; They have successfuly QUAD CHARGED it. I really feel like i&#8217;m no longer talking about cars, maybe I&#8217;m really writing about Intel quad core xeon processors. The core of the twincharger kit is a pair of Rotrex C30-94 Superchargers which are EACH rated for 44 psi peak and a peak of 600cfm (400hp) when injesting &#8216;free air&#8217;. The thing is, these chargers here are installed inline, with the factory IHI turbochargers feeding the inlets of the Rotrex Superchargers. To do this, the kit comes with a new intake plumbing kit including proper T-bolt clamps to make sure everything is secure in the engine bay under pressure. New high flow air filters feed uncompressed air to the factory IHI turbochargers, then the air is routed out to the 2.40&#8243; inducer of the Rotrex C30-94 where it is compressed even more. The [...]

		<description><![CDATA[Tweet The whipple supercharger is a unique and very practical chager. The unit is a great compromize between a positive displacement supercharger (that creates boost pressure by over pumping and over feeding the engine with air) and a compressor (similar to a turbocharger) that compresses the air inside the supercharger housing before sending it out to the charger piping.    The secret to this style of &#8216;hybrid&#8217; blower is the two intermeshed rotors of different lobe numbers (see illustration). The combination of an intermeshed 3 lobe and 5 lobe rotor means that the rotors inside the housing are operating at different rpms with a ratio of 5:3 to keep the rotation of the lobes (3 lobes to 5) in synchronsim. This complex design allows the rotors to capture air (in its natural volume) from the back of the blower housing, and push it foward as the screws rotate. As the air is moved forward it is captured and compressed between the intermeshed rotors as well as being pumped (in positive displacement) from the inlet port at the back of the charger housing to the outlet port near the front.      Because of this unique design, screw style chargers are [...]

		<description><![CDATA[Tweet   Our last articles about combining supercharger performance with turbocharger top end seems to have found some online appreciation. So, I’ve decided to write up a step by step on how to do the math for twin-charging your own car. I’m going to start with a typical compact car engine, such as the Toyota Celica 2.2 liter 5sfe engine. The engine makes 135 hp at 5200 RPMs with a 6200 RPM redline. For starters, every horsepower requires about 1.5 CFM of air (depending on the air density). So 135 naturally aspirated hp requires a flow of 202 CFM at pressure ratio of 1. The pressure ratio is the ratio of turbocharger or supercharger boost pressure divided by atmospheric pressure. Each 1 atmosphere is equal to 14.7psi of pressure… thus: PR = (14.7 + Boost pressure)/14.7 So for a normally aspirated car: PR = (14.7 + 0) / 14.7 = 1. Supercharger calculations: Using 14psi as our target boost (and the maximum safe boost we’d want to extract out of a roots style supercharger) we get the following pressure ratio: PR = (14.7+14)/14.7 = 1.95 New expected horsepower level: old HP * pressure ratio New HP = 135 * 1.95 [...]

		<description><![CDATA[Tweet If you&#8217;re interested in turbocharger and supercharger cars, then look no more! The Spanish have a saying about the world cup: “In the world cup, everybody plays, but Germany always wins”. This theme of Jealousy from the “German Machine” extends to other countries in Europe as Germany is an uncontested leader in EU manufacturing. One such example is a small Danish design and engineering firm that just released their first super car! Introducing the ZENVO ST1: I’m not sure what the brand name Zenvo stands for? Does come from a state of Zen that you reach being one with your machine? Does it come from novas or newness and innovation ? Or does it come from ENVY! I think it must be the latter for sure as why should Bughatti be the only European manufacturer delivering a road going supercar delivering over 1000bhp! Now Bughatti is an Italian brand but it is no secret that Bughatti is now managed by VAG (Volkswagen Audi Group) who are the visionaries of the Veyron and it’s 400kph jaw dropping performance. The ZENVO ST1 leaves the supercar market behind and enters the market as a Hyper Car, the term until 2009 that was [...]

		<description><![CDATA[Tweet The first time I ever heard of twin charging (using both a turbocharger and a supercharger on the same motor) was probably back in year 2000. At that time I was very interested in performance for the Toyota Celica and naturally I also read a lot about its sister cars (that shared some of the engines) such as the Camry and the MR2. One of the most interesting aftermarket parts I ran across at the time was the HKS turbo kit for the 4AGZE powered 1st generation mr2. The 4agze (for those that are not familiar with Toyota engines) is a peppy 170 horsepower 1.6 liter engine powered by the Toyota SC-12 roots type supercharger. On this car Toyota used an electromagnetically clutched supercharger that could be disabled during low power requirements such as cruising, and engaged when the user demands it. One of the most important parts of the HKS kit is the bypass valve. This valve was used to direct air from the supercharger to the engine at lower rpm/flow points. Once the rpm’s rise, and the engine starts to demand more air, and the turbocharger is fully spooled, the valve switches over gradually till the turbocharger [...]
