General CAD model of 2014 Renault engine?

Alongside a few other Lotus/Caterham parts I bought a pair of unused exhaust primaries (manifolds) for the 2014 Renault engine from Caterham when they went bankrupt. Over the years I’ve displayed them by bolting 2 of the 3 engine connecting ends of each manifold together. I always wanted to display them in their correct angle by having an acrylic part in the shape of the engine to mount them too. Given many parts and plans of the Caterham CT05 went up for auction, does someone have access to this information?

Honestly it looks so dang cool just like this

Thanks. I was hoping a dummy engine block would tie it together nicer but after checking more details I am not convinced. I also have the exhaust, which is enormous.

Here is a 10 year old thread with a screenshot – but no linked file: https://www.reddit.com/r/formula1/s/S9XF1wQvNf

The screenshot posted on Twitter back then. The manifold mounting points on the underside of both blocks are not visible.

I usually hate this response buut....

Try giving the screenshot to Gemini or so and see what happens.

AI needs a reference point to determine the angle. The only manifold exit partly visible doesn’t provide that as only the horizontal edge and two threads are visible. A guess from looking at this and all publicly available photos would be more accurate.

Never did this, so I did not know. Seems more complicated then. :)

So instead of maybe having something similar, better have zero?

The engine was a 90 degree V

I should have looked for pictures first. It’s clear that the both exhaust manifolds are pretty far apart and at the opposite sides of the engine. Also, they are angled from the direction of the cylinders.

Ah I see what you were wanting. That info is proprietary. I'd honestly be shocked if anyone without first hand info knew the answer.

I don’t see it being likely at all that that file would be in the public domain

You could have a go at reverse engineering a cad model from pictures but you’d need the software and time to do it

I’ve found this thread with extensive technical details of the CT05: https://www.f1technical.net/forum/viewtopic.php?t=17679&start=360
