I've not had great luck with the wrinkle finish in cans. They seem to be very sensitive to prep and application.

Insurance issues aren't going well today. I cheered myself with some retail therapy for the fuel system.

Alright ... so.

The straight through AN-6 screw on adapters are TOO BIG for the rails. By that, I mean they are too long. So they touch each other. I thought I had just enough clearance, but apparently not. So, instead, I ordered the AN6 push lock adapters. Those worked fine. So that's perfect. Plenty of clearance in there, and just enough for a short hose to each one.

Due to the length between the rails and the box, I also am going to use those as well coming to the rest of everything (exiting the box, going to and from the reg).

I'll have to take a photo of what I'm going for a bit later but I think I finally figured out a decent solution.

Now, apparently, from what I'm reading is that the pushlock hose is a different ID than the screw on AN6 adapter fittings for the braided line. I'm fine with this, but unfortunately am NOT SURE what the actual ID is. I guess I'll need to go look it up and get some clamps, but due to the suuuuuuuuper crunched nature of the air boxes and these itbs barely fitting, I don't see any other way to do it.

I am going to have to drill some holes in the airboxes to make this work. To my other dilemma is how I'm going to seal it once everything is installed so that it isn't sucking in outside elements like dirt and grime and getting into the airbox. I'll cross that bridge when I get there I guess.

I thought maybe I could look for some sort of grommet type setup that's maybe almost like a latex that will fit around the indents in the box where grommets would go, but tightens down around things like hose. So something super stretchable. LIKE AN AIRBOX CONDOM! GUYS! I'LL USE CONDOMS! Ok, just kidding. But really if anyone knows of anything that might work, I'm all ears. Otherwise I'm going to probably end up using some sort of rubber sealant that can be removed.

You can either grommet the holes like you mentioned or use a bulkhead AN connector like so:

of course that doubles your AN hose end costs and you have to make an extra line but its the correct way to do it. They also come in a variety of angles allowing you to choose your entry point if you need some space to route lines into and through the air boxes.

We'd "wet set" these with either RTV or Hysol into bulkheads on the aircraft I used to work on to prevent it from rotating and crap coming in.

I certainly do not mind extra cost. My primary issue is that some of the holes do not necessarily line up with things, and if I enlarge then, it's going to be a lot bigger than the bulk holes. I don't want to tear the air boxes up. Just put in what's necessary.

Good idea on the bulkhead. However, my concern on the hole that will be entering the closest to the entry way that needs to be drilled will be for one of the AN6 straight adapters, in which case, is probably a fair bit /too/ close. These ITBs are super snug in these air boxes.

Sorry I was editing when your replied. They also come in a bunch of different angles 15, 30, 45, and 90 are the most common so you can choose an entry point of the fuel line that works for you anywhere on the box then run the fuel line across the bottom or top to the rail entry point.

Just food for thought.

Cometic gaskets ordered. All the rest of the parts I needed to drop off are at the machinist. Things are going well. Picking up the rest of the fuel adapters and line today. Should have the air boxes rebuilt tonight or tomorrow night.

Sorry to see the 931 got hit again :( Hope it gets sorted out! I recently had good luck with the VHT wrinkle spray, Prepped, primed and sprayed, several coats per the can directions in 60-70 degree weather. When done, I took a heat gun back and forth to help the paint wrinkle. Was pleasantly surprised with the results and it seems to hold up well so far.

Another vote for the VHT stuff(and for the overall awesomeness of this project, of course!).

I've done a couple in blue and red; the red came out a bit orange-ish to my eye though. I used their self etch primer underneath. On the advise of other GRMers, I put on pretty heavy coats, then baked each part at 200 deg for an hour.

In my experience heat is a very important factor in getting the VHT wrinkle paint to work.

I used the VHT wrinkle paint too with good results. I followed the recommendations with the spraying at different angles, had the kitchen oven pre-heated and baked at the proper temp for the recommended amount of time.

I haven't uploaded any pics of the airboxes or progress. Will tonight. On a positive note, some time ago I emailed Valentino Balboni in hopes he might sign a plate for me to put on the car. Some time ago, the original owner had this car modified by Ultrasmith. Ultrasmith makes plates that say, "Custom made for: (name here)" with a neat little bull.

The owner after that apparently didn't like having the original owner's name on there, and had the plate swapped out with his name, without Ultrasmith approving it.

I've decided that I don't like that since it kinda ruins it for me. So the removal of the plate will leave an indent in the leather. So... I decided in place, to see if Mr. Balboni, my longtime childhood hero, would sign one I can put on the dash as a thanks to him and Lamborghini for all of the support the community has given me. Sort of the cherry on top for me, so to speak.

I sent it to him in october, thinking perhaps i'd never hear back, then woke up to this.

Well, after a lot of careful consideration, before I tore up the boxes, I decided I'm going to ditch them and make something else more custom. I'd have to completely rip the boxes up to make these itbs fit. One of the projects someone did was to delete the airboxes and mount them in the open. I personally hate that idea, so what I plan on doing is imitating the mounting style, and instead, go with custom plenums over it. I'll find a place that does plate aluminum tomorrow and use some heim joints to emulate the linkage spots. Shouldn't be hard since I have access to a drill press.

Seems like you've been hovering over that decision for a while. Sounds like a good plan

If you're going to do full plenums over the ITB's, to emulate the look of the air boxes, I know there's volume calculations to do in regards to stack height and plenum volume.

Though I still think a v-12 or V-8 with well sorted ITB's (either carb or EFI) is still the pinnacle of sexy engines.

Borla/TWM sell universal plenum for their ITBs. Just order a pair and they are lightweight and easy to adapt to your needs.
