BBi R&D: 3D Scanning and Reverse Engineering with Creaform and 3D INFOTECH

Garbage in, garbage out as they say. Reverse engineering is part of every day development at BBi Autosport when creating new performance upgrades or bespoke components. Speed, accuracy and simplicity is key when it comes to gathering data as this helps shorten the development cycle and increase quality. We seek to have OEM like fit and finish with best possible performance possible within every part. For a lot of our development we are using laser scanners to collect data - which allow us to create 3D snapshots of cars and components. This way we do not need to keep referencing the vehicle.

Chris from 3D INFOTECH brought over the latest offering from Creaform - the HandySCAN Black. This is a simple hand-held scanner featuring blue laser technology which performs great on dark and reflective surfaces. The way these scanners collect data is by shining laser beam flashes onto surfaces and using special cameras to capture how the lasers bounce back. Small reflective dots allow the scanner software to create a coordinate system and align all the snapshots together - creating a larger 3D picture. The speed of capture, accuracy has been greatly improved with the HandySCAN Black as it was very impressive how fast it soaked up all the details. What is also very useful is that the objects that are being scanned do not need to be stationary. The 991.2 Carrera T exhaust that we were scanning could be picked up, rotated and moved (as long as the dots are still on) which allowed for much easier and quicker capture.

How that data is handled is just as important as the scanner hardware. Creaform has a great software package that reviews all scanned points, consolidates and optimizes the points and forms a clean, easy to manage file to be used in parametric modelling software.

These scanners allow us to reduce R&D time and reduce dependency on having the vehicle physically in-house for the duration of the development. The 3D snapshots of the parts and car allow us to work within a 3D environment, creating components that would perfectly mesh with the factory parts as needed.

We will update more as we keep developing the Porsche Carrera exhaust system, how we use the data and how our concepts come to life.



Flying L Racing Ruby Star 991.1 GT3 RS BBi Exhaust Side Bypass & HRE R101LW Wheels


We would like to take a quick moment to present Flying L Racing’s Ruby Star Porsche 991.1 GT3 RS that we recently swapped out the bulky OEM side mufflers and replaced it with our BBi StreetCup Exhaust Bypass to reduce weight and deliver an aggressive exhaust note that matches the car's race-bred DNA. The side bypass is an excellent alternative to our popular center section exhaust bypass for those prefer a more aggressive Cup Car like sound and maximum weight savings. The factory secondary center exhaust weighs approximately 13 & 19 pounds for the Titanium RS and Stainless non-RS versions and our center section bypass weighs 8 pounds. This equates to only 5 or 11 pounds of weight savings depending on the variant.

To save the maximum weight, we took the same approach as Porsche with their Cup Cars, and bypassed the much heavier primary side mufflers. As shown on the scale, the primary mufflers are weigh approximately 46 pounds total for both the RS and non RS while our BBi bypass pipes are 5 pounds in comparison. That equates to a substantial weight reduction of 89% compared to the original weight of the OEM muffler that we replaced. For durability and protection against corrosion, each set is meticulously TIG welded using 304 aerospace grade stainless tubing with lower carbon content.
