Not a lot of time to post things. Working very hard to build A class truck race engines.
Not easy to explain what a A and B class engine is as a B engine can be an A class engine depending on the fuel system and engine management and turbocharger.
A class engine is build around a FIA 62mm inlet restriction in front of the turbo compressor giving it >6000Nm torque and about 1135Hp max.
Also new this year is that we start renting out ECU systems to race teams giving the driver more options on controlling engine power. Traction control is not allowed but over the years we came up with some data on what traction will the racetrack provide under different conditions and this is implement in the control strategy inside the ECU system.
Also spend a lot of effort on getting more fuel out of the Euro6 Volvo commonrail injector also used by Renault and Mack as it the same 13 or 16L engine. This camshaft is from a D16G Volvo engine and will be used for making a blank camshaft so we can build a billet camshaft for these engines later on.
