The good old front diffuser. Not sure why people dont do this more.

[@KenOs1109]

Magnifique les écopes en carbone 😊

[@Section501K]

Cool stuff, thanks

[@dsp.engineering]

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?

[@dorifto]

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

[@staycalm4952]

Do u have a video how to make a mold for hood or something?

[@po917k]

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]

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

[@DruNicholsMD]

What type of foam core are you using?

[@jpluim97]

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.

[@ajhartmanaero]

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

[@Fignewton117]

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.

[@michaelblacktree]

I think he did that in one of the wind tunnel videos.

[@Fignewton117]

@michaelblacktree ok I will have to go check them out

[@markcray5164]

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.

[@ajhartmanaero]

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.

[@neversettle7666]

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. kzbin.info/www/bejne/pKfcooqVltt6qrMsi=vVZFHazrd0cNLFee

[@Whiterqbbit]

I want to do this on a street car that may see track once or twice a year... lips are whack, splitters are life

[@ManuelGonzalez-mf5tb]

I Need a trunk lid and hood made for my 63 chevy impala. Where can I contact you guys. im In so cal

[@CJ5EVOLUTION]

You guys can make bottom car kits working out of a 3D scan cad model? This means without having the car at your place.

[@ajhartmanaero]

Potentially.

[@FZCarbon]

Hiiii bud, do you keep your vacuum pump running 24H until resin cure?

[@ajhartmanaero]

Only until the epoxy sets.

[@FZCarbon]

​@@ajhartmanaerothx a lot bud, appreciate it.

[@prestonedmonds4128]

What exactly do the tunnels do?

[@ajhartmanaero]

Make downforce
