I assume going to air-air simplifies things as well as shaves some weight. I know csf intercoolers are heavy af, no need for the heat ecxchangers and all that water/coolant isn’t light either. Any idea of how much weight you are shaving of the front end?

There is definitely some total overall weight savings vs original plan to have trunk mounted ice tank. Just the 5 gallon billet tank and liquid (no pump, lines, etc) is over 50lbs. Up front my guess it’s probably a wash. The intercooler core we are using is massive (55lbs without end tanks welded on yet). I’d have to weigh the CSF coolers to see what those are plus the liquid they would have held, it’s probably close.

I’ve never seen someone do a comparison of the two to actually show any differences. It was nothing more than familiarity with CSF and their reputation for building high quality cooling products. Ended up being a $3k “oh we don’t need it anymore” selection. |

Few minor updates as to where we’re at. Engine is out and disassembled on way to machine shop for getting new rotating assembly balanced and stock valve springs measured up to spec out some new ones. Turbos and all hot side piping out for heat shielding. A2A intercooler fab work underway and the little factory style throttle body inlet flanges we had machined up are ready for welding. This way we can weld intercooler piping directly to flanges instead of using factory plastic coupling and having to clamp to those. Fuel system is basically done as far as modified basket with new pump installed in tank and lines run. Latest round of revisions to port injection manifolds done and another set of 3D prints have been ordered which we will install when the engine is ready to go back in so we can do a final verify on all clearances before we have final design parts produced. Debating on wether we have them CNC’d or 3D printed in Aluminum instead. The custom strut brace/intake tube pieces we designed are being 3D printed in aluminum so we will see how those turn out. On a side effort, i have a pair of rear axles at a shop for hopefully getting an upgraded set made as well as I have a spare drive shaft that is going to another shop for a similar effort. After seeing pic of Mens Motors 8.8 sec M8 GC twisted pretzel driveshaft this will definitely require an upgrade That’s all for now, sorry no sexy pic updates to share.

Progress update… Fab work on A2A intercooler complete. First brace 3D print in aluminum completed matching part for other side printing now. Working with a shop to get a design and build project going on a 18x11 wheel that will replicate the OEM BMW 813M design so I can run a 305/40-18 Mickey Thompson drag radial out back and still have it match front OE wheel look and overall height. I’m planning on running a R888R up front which hopefully will be enough. This is going to require a rear brake setup change to go with something smaller so we’ll dig into that and see what we can come up with. Waiting for updated intake manifold proto prints due in next week. Still working with shops on upgraded rear axles and driveshaft solution. That’s all for now

Interesting, I would think a vertical flow intercooler would be better for this application in terms of how the car is setup from top flow to bottom flow where the intake manifolds are.

I think this configuration and layout is driven by the ability to use the space and open path for routing in the front corners where the now removed stock airboxes were located.

I would reconsider this layout as it might be clean and more beneficial for your system. Plus the fact that vertical flow intercoolers need smaller cores for large HP applications. Not trying to knock on what you have now. I'm just very big in fabrication and development just like how you're doing things. Something like this would be cleaner since you have two inlets and two outlets. |

Would’ve been nice if there was a CAN integrated flex fuel solution available like on some of the other platforms but these are all just part of the game in builds like this |
