Designing and developing race cars and components

Make Things Go Faster

@Motorsport _Engineering is the account of one of the most advanced classic car engineering projects anybody was ever stupid enough to embark on. Based on the 1969 Alfa Romeo GTAm, the twin turbo Hayabusa V8 will provide 850HP to the 850kg ground up redesign of the car.

This site lists various components and CAD models that followers request to be able to buy. I will update this occasionally based on requests received through the build diary on Instagram.

  • Scan data captured from real parts, within 0.5mm tolerance, and most critical dimensions validated to within 0.1mm.

  • STEP files included in the download package to provide a reverse engineered parasoled of the scan.

  • These scans are carried out by me on parts I have purchased or have been leant by kind supporters. None of the CAD available for sale is considered IP of suppliers or partners.

View fullsize I’ve put a couple hours into these pneumatic jacks. They are used to jack the car up and onto chassis stands, for larger servicing jobs track side. They integrate with dedicated front and rear jacking points on the car chassis. On the face of
View fullsize Here are some still images of the AB850 on the ground, a few weeks back. The set up of ride heights, camber etc. is a mile off, but this is the first time it came off of the trolleys. About 500kg in this state - targeting 850kg complete at 850hp. So
View fullsize Here are a few detailed photos of the front suspension rocker set up. They are machined from a single billet, supported on angular contact bearings around a hollow hardened 4340 shaft. There are 4 stages to the rocker. At the rear bulkhead the pushr
View fullsize These are the front corners, before they were fitted to the car. Lots going on here and a few things I’d like to review and potentially make changes for. They’re machined from AL7075 and hard anodised. I’ve heard since that 7075 an
View fullsize Fitted the rotary position sensors to front and rear suspension today. These contactless sensors use a magnet to provide a high frequency position of the dampers, with a redundancy reading incase of failure. I’ve switched to these over the line

View fullsize I sat down and drew in the main chassis loom last night, as it was annoying me having all the connectors loose. This has already been built and installed, but I like to have the model representative. Not much else visible this weekend. I’ve ha
