Preview: Defi Super Sports Cluster

Introducing the Defi Super Sports Cluster – this baby is not available outside Japan, but those that can afford the tag price (about Y230,000 excl shipping), you can turn to local tuner importers such as Monster Garage for help. Additional gauges added on to the vehicle serves as an informant of the current vehicle condition. But too many gauges will cause confusion and clutter the cockpit. The solution to this is to replace all the gauges with one unit. This all-in-one meter is a proud product of DSSC, displaying various information with a built-in data logger function.

Data logger will allow drivers to inspect the information after a run. The EL display makes it easy to read!
Defi’s DSSC Kit includes 2 temperature sensors, one pressure sensor, and a turbo pressure sensor. A maximum of 13 different types of information can be displayed by purchasing additional sensors. The installation is no different from hooking up any other gauges. The wiring job is made easy by having a pre-made Defi wiring harness which collects all the wires into one unit for easy plug and play. For existing Defi Link Meter users, the installation time is cut down, for the same sensors can be used on this new product. Replacing the whole stock gage cluster with DSSC is possible too, because of its functional blinkers and odometer. The bright EL Display inside the meter panel is one of the best features.	This display is very visible from any angle and it also clearly displays small letters. This is the most visible and organized gauge clusters on the market.With the remote control, simple and quick operations can be managed. The buttons on the remote controllers were carefully designed so that the driver can operate even while wearing gloves. The DSSC also has a real time data logging function. A SD card can be inserted to an attached control unit to maintain various data. That data can be read by any home computer to display detailed information to inspect the machine performance.

	This is the display screen. What and where to display the data can be set according to individuals’ needs and preference.			The tachometer lights up red and a warning light in the center will turn on when the peak data is displayed. The peak data for each category can be displayed.
	Unlike the previous Defi Link Meter, there are no buttons on the unit itself since everything is remote controlled. The SD card can be inserted for data logging purposes.			The buttons on remote control was designed so drivers can easily operate it even with racing gloves. The center of the circle button is dented, and other buttons remain higher than the controller surface so the driver can operate it without glancing at it.
	The P-LAP2 adaptor is also included in the kit. The additional display of maximum speed, lap count and best lap time can be shown with use of the P-LAP2.			The data logger screen hat can be displayed with a PC software was released. Various ways of displaying the information other than the line graph will be available upon release of this software. It won’t be included in the kit, but will be released as a set with the G sensor and logger software at the price of 30,000yen (about $330.00).

Review: AVOID Cyclone, Turbonator, Surbo, etc

Turbulence of the air in the combustion chamber is vital to the operation of all modern petrol and diesel engines. The main effect of the turbulence is to speed up the burning of the fuel / air mixture, and manufacturers like Cylone, Surbo etc claim that their devices create more turbulence. But can a “bolt-on” device really increase the turbulence in the cylinder? The simple answer is no – the flow in the intake system is already highly turbulent at part load, with air speed past the throttle in the region of 200-300 metres/second. A device upstream of the throttle may make the air swirl there, but the swirl pattern will be destroyed as the flow squeezes past the throttle blade. Injection of “a small amount of turbulent air” into the inlet manifold, as some devices claim, will have even less effect. It is interesting that the makers of such devices state with confidence that the device increases turbulence, but do not have any direct measurements of turbulence to show that this actually is the case. How, then, do they know?But don’t just take my word for it – there have been many studies, both direct flow visualisation and computer simulations, showing turbulence in the intake system. For example, Rai Alsemgeest at Warwick University did a study of intake manifold flow for Jaguar; see his presentation for full details. Here’s his animation showing a section through the intake manifold, where different colours represent different air speeds – red being the fastest and blue the slowest. Air enters from the left of the picture; the white shape in the middle of the flow is the partially open throttle blade:

It’s very obvious how incredibly turbulent the air flow is. There’s no way that a swirling air flow pattern set up before the throttle could survive and affect the burn within the cylinder, nor that a small additional air flow into the mainfold from a “bolt-on device” could make any significant difference. At wide-open throttle the air flow is much smoother, but from a fuel economy perspective this is unimportant as the engine spends 99% of its time at part throttle.

• Engines already have high levels of turbulence, and the physics is well understood
• Adding more turbulence can give only a tiny fuel economy benefit – this is proved by experiment
• Ignition must be adjusted to suit the faster burn, or the effect will be worse economy
• Increased turbulence at full load will most likely damage the engine unless the ignition is retarded
• Anything in the inlet manifold is extremely unlikely to affect in-cylinder air motion anyway

2006 Japan Rotary Festival Tsukuba

Rotary fans across Japan gather commence at Tsukuba Circuit! Every year on July 7th, (7/7) the rotary heads from all across the island of Japan gather at this designated spot. What makes this year’s gathering even special is the appearance of RE Amemiya’s Mr. Amemiya and Sanai Works’s Mr. Ishii had formed an organization called the “Rotary Tomo no kai”; meaning Rotary circle of friends. To celebrate the start of this organization, the biggest rotary meeting in the history of Japanese motorsports took place at the Tsukuba Circuit. Some events that took place were a talk show with the drivers and campaign girls in the paddock area, time attack on the course with shop demo cars, and a drift competition. The 4 rotor 767B made an exhibition run which pumped the adrenalin of all the rotary enthusiasts that came to this event.

	The engine virtually remains stock except for the Trust TD06-25G Turbo with 1 bar of boost good for 420 horses. This rotary feels more like the stock turbos with increased boost meaning it is very easy to ride.	The vehicle is 100% compliant with the Japanese vehicle inspection laws and as a bonus, the a/c and the stereo is still intact. With that said, the machine managed to tear up the Tsukuba Circuit at an amazing 59.1 seconds. This is the dream FD3S that every rotary enthusiast wants.
