If you click around a lil you'll find some pics and writeups about the other setups -- @JohnCh and I have traded a few, for instance. Your setup is different than our Duratec-based systems. For the sake of future readers, could you post a couple more photos while you have it open, and of course share your experience when it's all sorted?

Any idea how fuel is getting from the filler all the way forward to your can? From the photo I assume the evap line is coming from the very tip top of your filler neck, then plumbed forward to the evap can. Then usually a purge valve between the evap can and your intake manifold. "fuel in the manifold" is clearly not ideal. In typical operation I understand that the purge valve would open to pull vapors out of the canister, which USUALLY is not a big deal. But if you're getting enough fuel in there to fill that canister and overflow into a catch can (then overflow THAT), something seems not right? The fuel tank needs to have some ventilation -- fuel expands and contracts, and as you empty the tank something needs to let some air back in. I'm pretty sure I have a vent in my filler neck up near the top, but I don't have a photo handy. Either way, I'd want to be sure I understood why fuel was coming out of the tank and down that line; if you block or otherwise vent the same tube that's delivering overflow to your evap can, it will just deliver overflow to your floor or something.

My 2021 doesn't have an evap system at all. Is there a local emissions requirement for it?

I didn't want them embedded - the editor asked me. WOT is hard to record on public roads, it's a very short lived event

Traffic was trafficky but I did get some representative noises for you. The first one is from a stop and less cluttered with wind noise. For all these my phone was in the cockpit and got decent audio without being overwhelmed with wind and LSD clunking. https://youtube.com/shorts/axEG7ke-TZw https://youtube.com/shorts/QmZrpB6WMS8 https://youtube.com/shorts/e78X_kXYZ2s WOT at 7k+ in 3rd is something to behold. I'm not sure I have equipment capable of capturing that experience. My intake is on the left about 4' from my face, I dunno how much difference that would make. When there's a jersey barrier on my side I can hear the valves, on the right I can hear the exhaust. In fairness to my LSD I only really notice in parking lots. Once there's any throttle or speed it falls below the noise. BUT! It carries perfectly through a GoPro mounted to the roll bar. All this is to say you should really be working on your CFO to plan this project. In order, I'd do aero screen, ITBs, 13" wheels, then the half hood. Also double check the 13 profile, I didn't think they were so much shorter. You get a lot more sidewall, which (I am told) makes for a smoother ride. If you need I could attempt to measure my clearance at the sump but it's probably under 4".

my understanding is the clunk tells you it's working! it's the "everything is OK" alarm. 17k miles, still as loud as ever

If you have clutches you'll know it on every turn, clunk clunk clunk

it just started raining but if your CFO is receptive to gentle nagging I highly recommend the ITB route. My official review is "I can't believe they sell a Caterham with a single TB". I'll try to grab some audio when I'm out next. Yes, I have the ME221 running well. It has a "spark scatter" which can drop idle a little, so cold starts are great and hot idle is great too. If you do go the "new ECU" route I can't stress enough the value of the CAN gauge. I can keep AFR, TPS, RPM, and trim all on the screen at once so I can watch the tune even if the laptop is not around. I have a wet sump. It has touched a few things but not super hard -- always speed bumps. Squirrels and stuff aren't a problem. I would prefer more clearance, but I also like not touching my brake for right turns so ...

put one wheel in sand and goose it. you'll know pretty quick. I got ITBs from AT power, they're fantastic. Double-check the "pull" direction for the throttle hookup! I had to put in a new ECU, which was a /project/ but the outcome is fantastic. If you're gettin 13" wheels, consider 13x8 in the back. They look better, and once you get those ITBs tuned it'll help.

NICE. Have you figured out if it's an LSD yet? ;-)

Nice! The design looks like you could scale it in x/y to accommodate a smaller or larger passthrough

y'alls BaT stories make me feel very naiive.

I just participated in my first BaT auction (did not win), so maybe I'm just figuring it out. Doesn't BaT pre-load the fee on your first bid? Is it possible to back that out with "some story?" I assume they'd also have to get a new account after some small number of mysterious wins + backing-out...

maybe the minivan has 800 HP? that would explain it. I agree, that 200hp does not seem at all like what I drive to the grocery store, where pinning even 3rd is an absurdly short exercise. It does sound good on the video, tho

Quick meetup with another owner in town, I don't think he's on this forum. The BRG with wings is so nice...
