With a 1/2'' thick splitter, you could rout out the area around the cut out and then have a flush mount for the tunnels. You might need to increase the size of the tunnel perimeter flange, but that's no biggie.
Hey following you since a while. Started infusion by myself and i'm very excited about this topic. Can you tell me which vacuumpumps youre using? Saw in your oven built video that youre running 2 in parallel. Is this still your current setup?
Have you tried vortex generators on the trailing edge of the roofline? Saw a company that makes them and says they work but I don't see any numbers to back it up.
One of his more recent wind tunnel vids was on them, not needed on anything except really steep rear screens, depending on whether using a wing or not. Worth another watch if AJ can post a link.
Yeah we tried some on an E36, the Subaru, and several versions on the yellow mustang and not once did we get a positive result. They are all in the videos on my wind funnel playlist.
Per OP response, this is also backed up here. I believe the theory is to assist with activating the rear wing, however effecacy is minimal to nill from what I have seen. th-cam.com/video/nvyqW_avGtQ/w-d-xo.htmlsi=vVZFHazrd0cNLFee
Like the video. Question for you, the front on my car is kind of short, can the splitter tunnels be cut down a bit if there two long on my car? I under stand that they would lose some performance being shorter.
Cool video, as usual. Forgive me if you've already covered this, but have any vehicles with splitter tunnels added had the front downforce improvements measured?
@@ajhartmanaero ooooo interesting…..Also…have you seen the diffuser on the new Bugatti? They have some technical drawings online. You might find it interesting. Wonder if it can be applied to other road cars

This channel teach me so much 🎉 and the content is tailored to exactly what I need. Thanks a lot
The good old front diffuser. Not sure why people dont do this more.
Yep.... saved for later for when my parts arrive. 👍
Magnifique les écopes en carbone 😊

Is there a link to where to get that black closed cell foam?

I think he did that in one of the wind tunnel videos.
@michaelblacktree ok I will have to go check them out

Cool stuff, thanks
Do u have a video how to make a mold for hood or something?
You guys can make bottom car kits working out of a 3D scan cad model? This means without having the car at your place.
Potentially.
I want to do this on a street car that may see track once or twice a year... lips are whack, splitters are life

Absolutely. 80% of a tunnel is better than no tunnel.

Yes. We have cfd on our tunnels along with having run cars in the wind tunnel with them.

@@mikelmarion link?
is there a ballpark % estimate of downforce increase with a splitter tunnel? 5% 10% somewhere between 5-10?

What type of foam core are you using?
Hiiii bud, do you keep your vacuum pump running 24H until resin cure?
Only until the epoxy sets.
@@ajhartmanaerothx a lot bud, appreciate it.
What exactly do the tunnels do?
Make downforce
