New water tank system

[Richard L]

We are a new anorexia tank: 5L. Might work for some but fun to put in to the market place.
Please give me some feedback and comments, gratefully received, good or bad .

Assumptions - The holes in the middle are mounting point? Is it baffled? For a straight liner it would seem to be a great choice, but for a turner I would hope that it is baffled. Wondering if tilting it 90 degrees and mounting the low level and pickup on what is now the bottom might not be a better idea. Just initial thoughts. Looks like a repurposed water container to me.

Thanks for chiming in.

The four dimples are for keeping the tank stay in shape. Large plastic surfaces tend to loose its original shape in warm environments and filled. The dimples on each side of the tank are thermally welded together during injection moulding. They form a strong a single air-tight wall. If you wish to use those dimples for mounting purposes, you need to drill a couple of through holes.

I have worked on this tank for a while now. I shared your concern regarding liquid sloshing around during corning. As the width is only 2.6", side-way sloshing is of no concern. If the thin face is in the line of travel.

The tank is baffled no chance of sloshing in any direction. I will make a video to demonstrate it, time permitting.

The tank is a perfect square, 13" x 13". I am not sure your comment about tilting it 90 degrees. Please do explain.

If it wasn't baffled, I was suggesting turning it so that the water would have a gravity point. With the square bottom the water could slush left and right (again I didn't see or read about a baffle) so the suggestion for a cone at the bottom with the fill port at the top. If it's baffled it's not a worry.

I take it the weight isn't enough that it needs mounting from the top as well?

[Richard L]

The baffle is a long vertical dividing wall from the top (filler cap) to the bottom. The wall is approximately 3" from the outlet ports face.

The wall where the dimples met is approximately 3mm thick. It is debatable if it can withstand a negative 5G on a full tank (5kgs). How many G's on a 30 mph crash test?

Anyway, we are a bit concern about using just two 6mm bolts of the drilled dimples. We supplied two acetal stand-offs to filled the voids on the dimples, giving extra support. These stand-offs only comes with our purpose made bracket.

[Richard L]

See the two stand-offs inside the back dimples?

I saw the video posted last night on youtube. It didn't look to anti-slosh until I focused on the right side.

I think it's a great solution. Considering the thinness, it also wouldn't take much modification to stack a few side-by-side if you needed added capacity.

[Dust]

Pit Viper, that is exactly what I was thinking. Run bolts through the four dimples with the rubber/plastic? spacers, tie them together and go. I could see $100 a pop getting old quick though.

Richard, are the caps vented like the Howerton Engineering tanks are?

I think it's a great solution. Considering the thinness, it also wouldn't take much modification to stack a few side-by-side if you needed added capacity.

This planned already but we have not solved the unequal height caused the protruding bolt head if a water pump is assembled below. There will be a height difference of ~2mm. May be the rounded bottom of the tank wall provides a perfect solution.

We will supply four double length acetal stand-offs and four longer bolts.

The cap has a label with instruction regarding venting. Cap is not vented from factory.

The bracket is ergonomically designed to minimise installation time. Offering chassis floor or cross-rail mounting options. Four holes at the centre section of the bracket is intended for mounting an aquatec pump below.

Uses little space...

I'm thinking out loud here

Will need to check for space but thinking I could also use this as a buddy tank
For my existing howerton mini r53 boot install, perhaps mounting direct to the outside wall

Sound possible for a retro fit?

[Richard L]

Outside wall?

The tank is 13" x 13" x 2.6", check the side panel of the boot.

Here is a trial fit to a smart car:

Using outside facing sheet metal as the fixing point.

The sloping seat back is the challenge on a r53

Will be a very tight fit,

Might work if on slight angle or offset say -10 degrees from vertical

I have emailed you and jeff some pics of my mock up
Will be better than a thousand words here
