The bulkhead is clean and solid – like everything else on this race car.
MoTeC Electronics are used throughout the OnPoint Dyno Nissan 350Z. The sophisticated setup allows each component to talk to each other!The electronics on this OnPoint Dyno Z car are absolutely fantastic. From the button that activates the headlight flash to indicate a pass to the pit row sequence which automatically flashes the lights while in the slow zone – all controlled by the MoTeC PDM. Just a few minor facets that this car's electronics are capable of controlling. Every aspect of the electronics are fully integrated with all status updates and sensors sharing their findings over a network. For example, if the traction control settings change, that is shown on the dash but also this information is transfered to the ECU. There, the ECU adjusts the map accordingly.
There are sensors for suspension travel, wheel speed, brake pressure (front and rear), steering angle, various engine temperatures and pressures, transmission, differential, and so on. All of the electrical circuits and circuit draws are monitored and recorded. This data is all compiled for analysis purposes and can be replayed after a session to know what the car and driver are doing. Obviously, video can be syncronized to it and GPS data is fed into the dash – so they know exactly where on the track the car was positioned. You cannot get much more professional than this.
The MoTeC Power Distribution Module 15 – PDM 15 for short – is just one part of this system.The heart of the electronics is a MoTeC M800 ECU which, despite the fact that it came out in 2002 and is 14 years old, is still one of the most powerful on the market and has incredible capabilities. A MoTeC PDM 15 replaces conventional relays, fuses, and circuit breakers thus simplifying the system while at the same time making it lighter and more compact. The dash is a MoTeC ADL 2. A RaceGrade 15 button keypad provides immense customization for the manual implementation of the electronic features.
David Pratte (left) from Speed Academy was also present for the dyno runs with the 57 mm Jenvey ITBs. Dave is a great guy and I always enjoy the opportunity to chat with him. This time I was able to get an update from him about the Nissan Micra Cup Race that he particpated in at Calabogie Motorsports Park. And yes, if you saw the infamous video with Micra's all over the place, Dave was in that race but well out of the contact zone.Sasha's hesitation about power numbers prior to the dyno runs were verified. In order to get bigger numbers from the 57mm throttle bodies the heads are going to require some work. The numbers were respectable at approximately 380 whp but disappointing in that they were down from the 420 whp found with the 53.5mm throttle body setup.
From braking to aero to rubber to the mechanicals, Sasha's goal has been to create a very fast and extremely reliable race car that is fun to drive.Front braking is provided by StopTech ST40 calipers with knockback springs, StopTech Rotors, and Project Mu Clubracer pads. There are brake ducts to the front brakes. Volk Racing ZE40 18×12 wheels are wearing Pirelli 325 660 18 slicks. The stock brake pedal is currently still in use with upgrades including a Tilton balance bar and Tilton dual master cylinders. Factory brake lines are used with a machined block in place of the ABS.
