The Pipo P21 engine (alternatively branded as Glickenhaus by Pipo Moteurs) is a twin-turbocharged, four-stroke, 3.5-liter, V8 racing engine, designed and produced by Pipo Moteurs for use in the Glickenhaus SCG 007 LMH, from 2021 to 2023.
The engine is designed by French engine tuner and manufacturer, Pipo Moteurs. They used their previous experience with inline-4 World Rally Championship engines as a reference to design the new motor. However, due to the different rules between the series, there was only two components that were carried over, the 96 mm (3.78 in) bore spacing and cylinder head stud pattern. The engine has a crankshaft height of 96 mm (3.78 in), a deck height of 219 mm (8.62 in) and a bank offset of 19 mm (0.75 in). The firing order of the P21 is 1-8-3-6-4-5-2-7. Pipo Moteurs decided to use a symmetrical turbo for packaging purposes inside the Glickenhaus SCG 007 LMH. Garrett Motion was chosen as the supplier for the two reverse-rotation turbochargers.
The engine was chosen to power a reworked version of the Vanwall Vandervell 680 in 2023 before Vanwall Racing's entry was excluded from the 2024 FIA World Endurance Championship.
