Hi, I have been stalking the forum for some time and I can now give you a summary of my background and plunge into the EV world.
I am located in Brisbane, Queensland, Australia. I have been playing around in grass roots motorsport for about 12 years. Generally I compete in Autocross, Khanacross, Motorkhana, Hill Climbs and sprints. With the exception of the sprints all these sports are a time trial involving a standing start. I saw a Fiat Turbo Diesel doing quite well so I figured if torque is an advantage then electric motors are the way to go.
I toyed with the idea for a while before makign the decision to proceed in March 2015. I decided on front wheel drive as front wheel drive statistically has an advantage over rear wheel drive in my sports and all wheel drive is against our rules. I found an Advanced DC FB1-4001, built a chasis from the ground up and used a lot of running gear from a old Nissan Pulsar. By November 2015 I had a working prototype using lead acid batteries and a Curtis controller.
2016 was a bit of a development year while I sorted out all the teething issues. The first event was Feb 2016 (11 months after commencing the build). Over the following months I soon found the batteries and the controller were not up to the task. But even then I was placing in the top 25% of the all ICE field. I also experienced brake failures, suspension failures etc etc as expected with a first attempt at a home made chassis. Mid 2016 I converted to a Lithium Ion pack from a Chevy Volt and a 1000amp Zeva controller and it has transformed the car.
So far I have only entered in Motorkhana and Khanacross but I will soon enter some hill climbs too as soon as I have everything dialed in. My best result to date was a 3rd place outright in the 2nd round of the Queensland Motorkhana Championship. The car is better suited to khanacross as it is just as wide as a road car while most motorkhana cars are single seaters allowing them to dart between the obstacles at greater speed. Khanacross is more flowing and is suited to a car like mine with a firmer footprint and low centre of gravity. The car weighs in at 530KG without the driver.
I have at the design phase of my next project. I have planned to build a whole new car in parrallel. But recently I decided to build a new chasis but then transfer most of the components from the first car to the second. This approach will save a heap of time and make it more achievable financially. I realised I am losing some of my torque advantage being front wheel drive, so the new car will be rear wheel drive. I will take everything I have learned from the first car and apply it to the new one. I am confident I can reduce the weight by 100KG (hopefully more). That would bring the weight down to around 430KG. The weight isn't the main improvement though, the width will also reduce to make it more competitive in motorkhana. At this stage I am hoping to build the chasis by the end of 2017 so I can have the new car racing in 2018. But that is tight so I won't bet my house on it.
I will add some photos and videos shortly.
