Interesting. It looks like the front engine is right behind the grill, do you know how the cooling system is going to be set up? Dual radiators? Im guessing that this will see mostly track time or will it see time on the street?

Dual radiators rear mounted,would like to build for some street and standing mile events.

Holy moly, now this is adventurous! I like it, will be following this with great interest 🙂 I would imagine the drivers seat will be in the back seat, and fabbed steering/throttle/brakes etc...

This is crazy! Ive never heard of another engine driving a turbo to boost another engine. Is that possible? Wont the first engine have all the disadvantages of the turbo, like back pressure? Are you going to use two different ECM? What if the second engine makes more power than the first??? Wont it be dragging dead weight around of you run two seperate ECM's? Lol I need to know more about this build.
