thehelix112 Posted September 27, 2011 Share Posted September 27, 2011 Hey guys, I am in the market for a fuel cell. However, since I am going to be cutting up the back of my car, I figured I'd like to try and create some space for a diffuser if I should ever have the motivation for one, to that end, I want a fuel cell that when mounted flush with the floor in the back of an S30 will create a tapered slope from a low-point approximately level with the bottom of the diff, to a high point a few inches below the tail light panel. Unfortunately all the "wedge fuel cells" I've been able to find are all essentially upside down versions of what I want: http://atlfuelcells.carshopinc.com/product_info.php/products_id/115290/FC140 What are my options? Custom? Or is there someone that makes what I am looking for. My desire for this was affirmed when I saw this too: http://forums.hybridz.org/index.php/topic/102290-bsr-nos-imsa-260z-cage-photos/ specifically: http://s160.photobucket.com/albums/t177/psanders240/BSR-260Z-IMSA/?action=view¤t=jeffery-R1-E015.jpg Thanks, Dave Quote Link to comment Share on other sites More sharing options...

JMortensen Posted September 29, 2011 Share Posted September 29, 2011 Tilt the fuel cell.This is a 12 gallon. I expect I might only get 10 in it now... Quote Link to comment Share on other sites More sharing options...
thehelix112 Posted September 29, 2011 Author Share Posted September 29, 2011 Well.. Er... Yes. You could think of doing that, if you weren't a complete retard like moi. Thanks Jon. Dave Quote Link to comment Share on other sites More sharing options...
Kevin.pk Posted September 29, 2011 Share Posted September 29, 2011 lol.... I don't know any sources for a cell that is tapered like that. If you are set on it though, I think your best bet is to have one fabricated by a shop. Mainly because if you do find one, I doubt it will be at the correct angle to match the slope at the back of the Z. Quote Link to comment Share on other sites More sharing options...
thehelix112 Posted September 29, 2011 Author Share Posted September 29, 2011 I think I'll just do what Jon suggested. Simple and cost effective. Now I need to figure out what sort of cell to get, and whether I should mount it with the sump facing forwards as due to the tilt that's there the fuel is going to be.. I think that makes sense?

JMortensen Posted September 29, 2011 Share Posted September 29, 2011 My pickup was at the right rear, so I flipped it backwards. Quote Link to comment Share on other sites More sharing options...
johnc Posted September 30, 2011 Share Posted September 30, 2011 Or build a wedge shaped box for the rectangular cell. Just need a false floor so the rectangular cell sits level. Quote Link to comment Share on other sites More sharing options...
thehelix112 Posted September 30, 2011 Author Share Posted September 30, 2011 John, Is there anything wrong with just tilting the fuel cell? Mounting it up higher isn't going to help the CoG, though it will certainly clear room for a diffuser. Dave Quote Link to comment Share on other sites More sharing options...
JMortensen Posted September 30, 2011 Share Posted September 30, 2011 I think having it angled will improve the reliability of the pickup too. In my case it really is just a tube in the corner of the cell. Quote Link to comment Share on other sites More sharing options...
thehelix112 Posted September 30, 2011 Author Share Posted September 30, 2011 Makes sense to me. Quote Link to comment Share on other sites More sharing options...
johnc Posted September 30, 2011 Share Posted September 30, 2011 You're not mounting it any higher up by building a false floor. Your diffuser should have an angle of 7 to 10 degrees and in most cases (with a 8" deep cell) the cell top is close to flush with the trunk floor. Also, the issue with a fuel cell out back is yaw inertia not cg height. Moving the cell as far forward as possible while still allowing room for a ratchet to get the rear diff nuts off is more important that a 2" install height difference.
