You haven't seen the production kit pictures of our single turbo kit. Compared to the prototype system on our car, the runners are 50% shorter, more equal length and the merge is at a narrower angle. Don't see how much more of an improvement is possible given space constraints. And FWIW, the head fabricator at FFTEC used worked at Full Race. He's quite exceptional.

Using a mid to large frame EFR turbo has a potential packaging advantage in that it has an internal wastegate. But the physically longer CHRA and huge turbine and compressor casting does require some compromises with the rest of the kit to make it fit. We had a few EFR turbos on hand during the development process so we've looked at everything from a number of different angles, both figuratively and literally. In the end, fitting a custom turbo kit in a car requires some compromises. It's just a matter of picking the lesser of two evils from time to time.
