Building a fast car is one thing, building a show car is another. Combine the two and you have a pretty hard job on your hands. Ogura Racing Clutches (ORC for short) has been in the aftermarket tuning game since the beginning. Their lineup of racing and street clutches has for years earned them the respect they deserve, and their experience in the racing field has helped greatly advance their products. And so for 2006 they thought it would be a good idea to go all out and create a car that would not only attract crowds during this year's show season but also perform like no other on the road: Enter the ORC twin-charged 350Z.
In essence the system is very simple. The V6 engine spins the Blitz turbocharger through the specially built exhaust manifolds, which in turn feeds the intercooler. Then a large diameter pipe directly connects the intercooler to the supercharger intake via a mechanical throttle body. At low rpm, when the turbocharger can't muscle up enough positive boost pressure, the supercharger compresses the intake charge. Once the turbo spools up, the supercharger is cut off via the pulley that drives it directly from the crank. If that wasn't enough, the ORC is fitted with four Nitrous Express nitrous oxide tanks, which, when used, can add an extra 100 PS! That would effectively make this Z triple-charged!!! ORC staff wasn't too keen to demonstrate the effects of the additional (third) charging system, no doubt concerned about the engine's wellbeing. After all, it's already quite impressive that they're getting results like this from a standard unit. The nitrous system also feeds the intercooler cooling circuit, which, when needed, can dramatically reduce the intake charge by spraying freezing gas onto the main core. Sending the unrelenting power to the gearbox is an ORC twin-plate carbon clutch, which is as easy to use as a standard factory unit. A Nismo 1.5-way limited-slip differential has been fitted between the driven wheels taking care of unleashing all that torque to the asphalt.
