Why not place it in the wiper cowl or through the fender?

Either of those are probably good locations. When the car is not moving, the air in front of the radiator gets about 10 degrees hotter. Also, I think it would help to move the sensor to the edge of the filter cap.

The bigger air filter with the silicone reducer just barely fits:



Also, I had a version printed as a two piece mold and was able to get the part out without the mold breaking this time. SLS nylon is so porous that the silicone doesn't like to come out cleanly. Im going to print another version as 3 peices (two sides, center section) which will help with release and allow me to paint and polish the inside surfaces to make them nice and shiny.

Also why do you need the open element sensor? The stocker sensor will work fine. You're measuring ambient temperature, not the temp after the hair drier.

Because it helps with things like hot restarts and whatnot. And like alec said, the air in front of the radiator gets hot when sitting. Speed density is more touchy with AIT than MAF.

Right but if you put it in a spot that wont get heat soked then you'll be fine. AKA through the firewall into the wiper area or the fender. Hell with the stock sensor its all plastic, you wont even need a filter on it.

Wiper area will be a lot cooler than in front of the radiator idling in traffic.

One thing I love about 3d printing is that you don't pay for complexity. Also, shapeways likes smaller models so it was actually about $10 cheaper to get this 4 piece mold printed than the two piece version:

Probably should get an efficient production process nailed down before developing for the NB.

I had to bail on the first run due to unforeseen circumstances. Hoping to get in on the next one.

I don't really have plans for an NB version. However, next time I have one in front of me I will look around for areas to draw external air from. My understanding is that there is a hole near the fender.

Also, fwiw there are no runs on this. I can still make people the gen1 carbon versions I have posted a few pages back but I am finishing up tooling for the new design which will be superior in every way (flow, strength, cosmetics...). Each part is made one at a time by me, so no batches or anything resembling mass production.

Is email still the best way to get an order in? When do you estimate the new design will be ready?

Hard to say. I need to finish up some details first, and my day job has had me working overtime lately. I am hoping to get the cad files finished this weekend, then get quotes for machining. If all goes well, June?

If it turns out to be cost effective to make parts with this tooling, and there is demand, I am looking at devoting a set number of hours/days per week to making parts and then scaling that to how much demand there is.

Canadian non Airbag cars did not have the hole.

My dumb 1990 doesn't have the hole either. Has (or, had) AC, however.

Well I guess that's not it. I do know all the non airbag ones I've seen in Canada don't have the hole.

Rover is an early '90 build (vin number <6000, came with a smooth-fin 1.6L diff) and doesn't have the hole either. I'll measure and cut it in the shell myself.
