In a continued effort to find a possible solution to adding an oil tank, I Googled tank companies today. I found one that will build a custom tank in any shape I want: Stef's. I gave them a call, and it seems like they can really build just about any shape, so it's up to me to determine the best shape...
I posted a picture of my cylinder that I made yesterday. Here are some shots of me trying to fit it. You can see, it's really tight, especially to the header:
I just don't think that's going to work, and this is a 2-gallon tank. I'm getting conflicting opinions as to whether that's big enough, which means I should probably target something larger.
So I pulled out the tape measure and came up with some dimensions. Then the box cutter and cardboard.
This was a 12x12x5 box. It needs to be angled at the inner fender which cuts down on the available volume, but I also can go a little deeper at the firewall/back side. Doing a lot of math, I've determined that I can get a total volume of between 2.75 and 3.25 gallons. The effective volume would be less, as there has to be some air space at the top where the oil return comes back in.
Tomorrow I'm going to build some more models after doing my calcs. Making a box like this will restrict access to some things (#8 plug, although I can still get to it), the rear-most UCA screw (which I can get to from the bottom). But it may be a viable option...
More to come...
