There's not much room, I wish we could find a thinner fan (I know this is unlikely since BMW used a PID fan with variable speed) and run a duct up to the left of the plenum intake tube.

Awesome project, I expect I'll start a similar project soon but focus on reducing drag/increasing efficiency as I'm sticking NA. Time to learn how to lay carbon and mold some ducting in that cramped space haha
I beat the piss out of my car in all temperatures for short and extended periods of time, and it never gets hot. Gets warm, but never close to the limit.
Vented hood, CSF cooling package, NA, 6-speed. They don't need much to work. Can always make them better but it's pretty easy without FI and DCT.
Yeah it seems they're pretty stout from a cooling perspective with just the Do88 package, even DCT. I just can't get the N54/S55 heat issues out of my mind. I've only ever tracked turbo cars but I'm a believer now...
