Exhaust pipes remain one of the last bastions of hand fabricated metallic parts on an F1 (along with radiators). While we can all marvel at the metal shaping and immaculate welding, the exhaust is also a key tuning aids for the engine and highly influential on aerodynamics too. So here’s a quick dive into some of the unseen technicalities and details of the F1 exhaust from the normally aspirated V8 era.
A rarely seen part that came with some other R&D mock up parts is this Hydraulic fluid reservoir. This small unit keeps the hydraulic pump fed with fluid, although the example I have a 3D printed part and the finished part on the race car is more likely to be a carbon fibre piece.
Set up sheets have always fascinated me, they are the document used to list the hardware and set up to be used on a racecar, before its dispatched from the factory. My latest acquisition has been three Arrows set up sheets from 1997, covering three separate tests with three different drivers at two different tracks within the space of four months. It gives us insight what is included in the set up sheet, the actual set up differences and provides of a story of the team’s year.
This is a just a quick post taking a brief look at a mid-nineties F1 throttle pedal, this particular pedal is a Jordan part and made in carbon fibre.
When looking at the installation of any Hybrid or Electric racing car, the bright orange cabling is a trademark feature, taking the high currents between the battery, inverter and eMotor. With light weight, reliability and rapid disassembly all factors in the cabling installation, the cable choice and the connector technology are critical and often unappreciated by the fans. I’ve recently purchased some Ex-F1 DC connectors\cables which give us some appreciation of the tech involved here. These are both Red Bull RB8 (2012) parts, taken from the DC (battery to inverter) bus. Rather than simply being big fat copper cables with two pin connectors, they are remarkably complex in their design.
During the F1 KERS era (2009-2013), Red Bull Racing adopted a unique battery set up. Rather than in a recess under the monocoque\fuel tank, the battery is split up into three separate units around the gearbox. I’ve explained the KERS installation in previous posts (LINK), but I’ve recently acquired a 3D printed mockup of one of the side mounted battery cases. This gives us some unique insight into the battery case’s dimensions and layout.
Mercedes AMG’s W06-Hybrid dominated the season this year. I’ve been lucky enough to get close to it and find out lots about its design and details. So I’ve put together a comprehensive ‘walk-around’ the car, from my camera phone pictures taking whilst being in the pit lane over race weekends.
The Drag Reduction System, DRS, was introduced to F1 in 2011. It’s a system to open the rear wing flap for reduced drag to boost top speed. Over the subsequent years DRS operating mechanisms have evolved and converged on the same set up, with a wing mounted pod containing a high pressure hydraulic actuator to pull the wing open. This is an opportunity to see the mechanism in detail and explain how the set up works.
This 2014 Caterham front upright shows some of the key design features of F1 uprights, although as you can see it is both a 3D printed mock up part and also part of a pull rod front suspension set up. F1 Uprights are the part that completes the front suspension geometry, connecting the axle to the wishbones, whilst also providing mounting points for the brake caliper, pull rod and steering track rod.
