For this years school project we are going to attend the "Shell eco marathon prototype" race. We are in the designing stage now and i'm wondering if anyone has made any HATZ engines yet (as we are not the only competitors and most certainly not the only one using this engine). To be precise, i'm talking about the 1B20(v). If so, it would save us a lot of time which we really need to design and create the prototype.
I'd suggest reaching out to the manufacturer and requesting the 3D model. A lot of times, they are willing to provide them. They have one for sure, because I've seen renderings of these engines in their promotional literature.
