Is this BMW E36 build the most radical Hill Climb monster in the world?
Bimmerworld’s ‘Bergsteiger’ was built for Pikes Peak, and at The SEMA Show’s Optima Batteries booth, chassis guru Wayne runs us through some of the thought that goes into a dedicated Hill Climb build. After selecting the Roush-built 1150HP Weistec Garrett GTX3076 turbocharged V8 P63 engine (the S63’s motorsport variant) and doubling the output from a GT3 BMW M6 IMSA WeatherTech SportsCar Championship build it was quickly apparent that a tube frame chassis would be required to the accommodate the size of the engine.
Some insight into the aero setup is shared, including the requirement for 2000lbs front downforce to match the rears 1800lbs at 150mph along with some of the layout decisions and placements required to get that car to a weight of 1100kgs (2400lbs) with a 50:50 weight distribution. A carbon fiber widebody and lightweight Forgeline GS1R rims wrapped with Continental tires also help keep that weight down.
A Bosch Motorsport ECU is used along with a MoTeC dash display for logging and driver data on the electronics side of things, the suspension is looked after by Motion Control Suspension and Bimmerworld components along with PFC brakes to handle the demands of high altitude racing.
