thinking about how to get airflow to cool the chain, leaning towards a NACA duct over a scoop since I don't think I'll need a massive volume of air

maybe two of these, one on each side. could also use it to route air to the airbox
Anyone have a recommendation for a cost effective low pressure fuel pump? Running a swirl pot type setup, already have the high pressure part sorted just need the low pressure side
planning on moving the fuel tank to the front, which would necessitate a custom fuel cell. On a scale of 1-10 how bad of an idea is it to try to build one myself as someone with somewhat limited welding experience? I figure with the cost of a custom cell, that would cover a lot of wasted material
Trying to figure out how to mount the shifter for the Foward-Neutral-Reverse box, thought about getting one of those circle track 2 lever shifters and having one for the trans and one for the FNR box, but I think its a recipe for disaster having the shifter and the lever that put the car in reverse right next to each other. Anyone have an idea for a convenient way to mount them? maybe still have them next to eachother but work out a lockout mechanism for the FNR box?
whipped up a CAD mock-up of my fuel cell. Ends up at 29x16x6, which happens to be one inch smaller in each direction than a commonly available size. Trying to decide if it's worth it to start with that and modify it or start from scratch. Looks like there's more room but due to the curvature of the compartment I can't go bigger without a complicated geometry
That will block air for heater/ventilation etc.
In reply to TurboFource :
I'm aware, don't really need a heater in Georgia, especially since this is gonna be mostly for track. Might rig up a 12v hairdryer for defrost though, lol
If they make a fuel cell almost that size that works out of the box, I'd just run that. Besides, unless you're running enduros (not sure), the lost capacity won't be a big deal for a track car.
they make other options for heaters that are better than a hairdryer!
for your shifters, to assuage your concern about shifting the wrong one, can you mount the fnr shifter on the left side of the seat? Or somewhere else a little more inconvenient than right next to the main shifter? Or bend the lever 90 so it's there but you have to grab it more intentionally
In reply to jfryjfry :
unfortunately there's really nothing that will work as far as fuel cells, everything will need modified. 8 gallons would be perfectly fine, but if I'm gonna be modifying a tank or building one from scratch, I might as well make it a bit bigger, ~10-12 gallons. I'm not even thinking about a heater right now, I'll cross that bridge when I come to it.
Good ideas on the shifters, I also thought that maybe a pull handle under the dash, kind of like the original parking brake handle might work. unobtrusive but accessible
while changing out the front swaybar bushing on my cayman before i hand it over to the buyer on friday, I saw the NACA duct on the undertray 
(not my pic i was rolling around on the asphalt instead of strolling about under a lift) and thought "oh yeah there's airflow under the car that i can redirect." so I might end up putting ducts there to cool the chain and radiator.
Also, I was looking at cheap fuel cells and saw a review complaining about how they were smaller than stated by just a little bit. Sucks for the reviewer, but if it really is a little bit smaller than 30x17x7 it should fit perfectly in that tray. I ordered one to arrive tomorrow so we'll see
One thing about under car air as a cooling source... air near the pavement may be hotter than you think. It also at times can be dirty. I thought about it as a source for cooling air for the Outlaw Bug, decided against it after some crude testing.
Just saying. YMMV
hmm that's a good point, the asphalt definitely gets hot here in GA in the summer. The temp on the chain is supposed to stay under 160, so if I'm pulling in 130 degree air from off the pavement that is less than optimal
as long as i don't have to do this I'll be fine with having ducts on the side I guess
In reply to gixxeropa :
That is a really cool looking air pod case. 
I really like those air inlets.
Can you use a small fan, or maybe some hose with a bilge fan in it?
In reply to TurboFource :
I'm gonna have a fan on the radiator, but I wasn't really planning on it for the chain, as theoretically it shouldn't need to be cooled while stationary, and its need for cooling should increase with speed, so I figured just a scoop or something should work well. But a fan is possible if that's not sufficient
Got some stuff coming up, but need to get my truck, trailer, and race car ready before I can devote more time to the europa, as well as make space in my garage by selling off the old chassis. But for the moment, I could use opinions on the eventual livery for the car. I'm deciding between the traditional lotus green and yellow, Gold leaf lotus, and a spezi can livery that has nothing to do with lotus. pics below
like this but I'd add a yellow strip below the doors
not sure how i feel about the gold vs chrome bumpers on this one
just the colors, wouldn't add the logo. I like the idea of bright colors, might help me not get run over by a mallcrawler.
would also accept any other ideas, as long as they're cool. No solid colors I want pizazz
Hard to go wrong with the traditional lotus green...but if you want pizazz, the spezi would be loud!
The aforementioned Amazon fuel cell didn't fit :( it was smaller than advertised but not work small enough.
but then I just ordered a custom fuel cell from RCI. $300 delivered with a fuel gauge sender. 
unfortunately this means I don't have a reason to buy a tig welder anymore :(
The best thing about this situation is I just dumped the Amazon cell off at ups and got a refund same day
Gold Leaf
Spezi.
But im Italian and like everything flashy as berkeley.
No matter which way I go it likely won't be permanent. My plan was to paint it a solid color (I guess black would be best for this?) and then do a wrap with the design, so I'd likely change it up every few years
Some pics from the shop building my chassis. The idea for a bike engined europa was one I've been thinking about for a while, I was actually shopping for one or an opel GT to convert when I came across this guy that had built them before and had a ton of experience with Europas as well as building Formula 1000 cars. Plus his price was reasonable enough that I wasn't sure I could beat it doing the work myself after accounting for buying tools and money lost to mistakes. So I decided to farm out the chassis to him and I could do body, electrical, and the fuel system, which would take it from a multi-year project to a 6 month-1 year project.
Also, that 850 is everything on the chassis except for the axles which are being made right now, so I'm excited to see how much it weighs all put together. Aiming for sub 1200 pounds
