MX5 Hillclimb car

We’ve been building this hillclimb car for Practical Performance Car Magazine. The full details of the build will be available to read over the next few months. PPC mag have an event called the 999 challenge. The idea is to build the best MoT passable car you can for 999 quid and carry out  a timed quarter mile and handling course. The fastest car wins. We decided to take the concept a step further and see if we could build a hill climb car for full competition still sticking to the 999 pound budget. The list of modifications is massive. We reduced the weight by about 20% which is hard going on a car that’s so light to start with. With all the weight stripped out we built a cage that not only keeps the driver safe but adds to the shells rigidity. The engine received a turbo and anti lag system including launch control and flat shift. It also features a hydrogen gas system for better combustion and a cold water spray for the intercooler. We carried out a few suspension and brake modifications and thoroughly set the cars geometry to give it perfect handling. The aerodynamics were last to be addressed and are controlled tightly by the regulations. We designed an aero package that other than the allowed rear spoiler didn’t change the cars silhouette. We achieved this with a flat underfloor, undercut splitter and a rear diffuser than uses a cut out into the rear bumper. The rear aero is fed by the exhaust gases between the spoiler and the diffuser which aid flow attachment. There’s still some fine tuning to be done but it should be an awesome package on a very tight budget
