Added the remote breather vented from the bitch tube
And finally ... a pic with me in it
Car handles noticeably better with the wing at highway speeds. Feels a lot more planted. I'm really pleased with how it turned out.
You know we have to add a splitter now .... LoL

Interested to see what you come up with for the splitter, I need to build one for my new car.Comment

Will do.
We're going to dial the ride height down from "F150" (to get out of our driveway) and down to race mode, see where we're at."And then we broke the car. Again." Mark Donohue, "The Unfair Advantage"

Finally updated the diffuser to cover the full width of the car. Been wanting to do that for some time. Looks way better.
Also changed to lighter weight oil. We were running Molly 10W60 since I had it around for the E39 M5 but it's WAY too heavy. Oil pressure was 60 psi hot idle, 70 psi WOT. Switched to 30SAE VR1. Now we're 20 psi hot idle, 40 psi in turns, 60 psi WOT. Perfect

Beginnings of a splitter. Rough dimensions, locations of supports etc. Tunnels are cross hatched. We'll use this to CAD a template with better symmetry. It's a start.

Looking good. I bet if you pick Johnny @ Nine Lives brain, he'd be glad to help out with the splitter design.Comment

Friend of mine was lucky enough to have VIP access at the Reb Bull Racing UK facility. After researching splitter design all week, it's easy to see how these work now. Our splitters sit under the front of the car, theirs hang out in the breeze in front of it.
Lots of side aero going on as well.

I like the splitter tunnels. :)Comment

Tunnels make a big difference. See below, with and without. More blue, more downforce

LoL. No aero penalties in NASA ST1/2/3. I can hang aero bits all over this thing. My crew chief just frowns and mutters "Drive faster ...""And then we broke the car. Again." Mark Donohue, "The Unfair Advantage"

Splitterama
Started with 1/2" oak plywood
Cut the sheet to 72x36 and started adding cutouts
Measured for fit to the IS valence. I had it upside down last time. Nobody noticed LoL
Planning the tunnels. Tire profile is black cross hatch bottom left
And finally done this phase. Good progress for an afternoon
