johnc Posted June 28, 2002 Share Posted June 28, 2002 Finally got to the back of the car to take some photos of the fuel cell mounting frame Bill Savage put in. The loop on the right of the cell frame is the mount for the fuel filter and pump. And the next photo is of a really cool rear tow eye. Its really light and I can jack the rear of the car up using that a the jacking point. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 16, 2006 Share Posted December 16, 2006 Hey John, would you mind putting these pics back up? I just got my Xmas present from Fuel Safe and I know I was pretty impressed with the way you had mounted your cell. I remember really thin straps, but can't recall the frame work and I'm a little confused as to what to do there because of all the bolts around the perimeter...

JMortensen Posted December 18, 2006 Share Posted December 18, 2006 OK, anyone else have a road race type cell installed with clear pics? I've looked and all I can find are the Jeg's type cells... Quote Link to comment Share on other sites More sharing options...
hotimport Posted December 18, 2006 Share Posted December 18, 2006 Well here you go, i thinks this right here is one of the best setups yet to go in Zcar! http://forums.hybridz.org/showthread.php?t=111604 Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 18, 2006 Share Posted December 18, 2006 Here is a pic of what I have: http://www.speedwaymotors.com/xq/aspx/path.2005/img.91053440_L.jpg/deptId.58/displayId.2271/qx/ProductLargeView.htm See the flange at the top? That is the part that is giving me some trouble. I saw bjhines's setup, that's pretty sweet. Mine is a bit different because it has bolts all the way around the flange that sticks out at the top. I could make a frame very similar to what he did, but then I'd have to either replace all the bolts with longer ones and make them go all the way through the frame (PITA with my crappy drill press), or I could maybe make the frame out of angle iron so that there wasn't so much thickness to it and then maybe the bolts that came with the cell would be long enough (maybe, they're really short). John Coffey's frame I think had a round tube in front and back and thin straps, but I can't remember seeing the side parts of the frame which left me wondering how he dealt with the top flange part, if his cell even had a top flange, and I can't remember how he kept it secure vertically...

hotimport Posted December 18, 2006 Share Posted December 18, 2006 Uh, yeah its a bit uncommon. I wish i could help you on mounting part, but i dont know if you maybe want to make a support on each angle of the cell instead of all around. If the bolts are short as you mention, there no good anyway if you going to be making a support around the flange, then just replace them with longer ones and strap it in.

zlalomz Posted December 18, 2006 Share Posted December 18, 2006 Some IT Z's used thick wall 1 inch tubing in a rectangle that the flange sat on. The tubing was drilled and tapped and the cell bolted directly to it. That's how the Rebello guy did mine. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 18, 2006 Share Posted December 18, 2006 The other question I had is if you do bolt all the way around the flange, are straps even necessary??? Seems like they'd be overkill at that point. How was yours done Steve? Quote Link to comment Share on other sites More sharing options...
zlalomz Posted December 18, 2006 Share Posted December 18, 2006 No straps. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 18, 2006 Share Posted December 18, 2006 Thanks. That might be the way to go with this cell. Quote Link to comment Share on other sites More sharing options...
hotimport Posted December 18, 2006 Share Posted December 18, 2006 I pretty sure if you were to mount it that way, there probably wont be nesessary to strap it, but for sefety puposes you would have to do it. I am no expert at this but when i will be mounting my cell i will do everything possible to keep it in place securely. Quote Link to comment Share on other sites More sharing options...
bjhines Posted December 18, 2006 Share Posted December 18, 2006 I might chime in here.... I looked at the tanks with the top flange... That is what I would have preferred to use... For the mounting system I would have made the same frame I made for my cell... then drill holes to clear each fastener... I would then use 6-8 clamps held with 3/8" hardware the went through the square tubing... Quote Link to comment Share on other sites More sharing options...
johnc Posted December 18, 2006 Author Share Posted December 18, 2006 Updated... FYI... the fuel cell I used was a custom ATL with a 7 degree bottom rise and an aluminum can. There was no mounting flange on top, it was just a big aluminum box. That's why it was strap mounted. Quote Link to comment Share on other sites More sharing options...

JustinOlson Posted December 19, 2006 Share Posted December 19, 2006 Could you mount a standard metal fuel cell at a 7 degree angle without issue? I wonder if there would be fuel pump pickup issues. Justin Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 19, 2006 Share Posted December 19, 2006 Looking at my new one, it says the pickup is in the right rear. Maybe if it was installed backwards so the pickup was in left rear. That was kinda my plan, but it would be nice to hear from someone else that this works before I do it... Quote Link to comment Share on other sites More sharing options...
bjhines Posted December 19, 2006 Share Posted December 19, 2006 We run tracks in both directions... Mine has an internal sump... but the bottom is flat... there is little room for me to angle mine... I am actually considering raising my tank to clear a rear diffuser... Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 19, 2006 Share Posted December 19, 2006 Oops, I meant that the pickup would be in the left front, not LR. I'm not too concerned about the pickup location, I've never had fuel starvation issues and if I ever get around to doing the LS swap I'll just put a small surge tank in there. Right now I've got 3 surge tanks in the carbs, and until I run into issues i think I'll let that be good enough. I wouldn't be inclined to raise the tank for a diffuser. I suppose you'll know better what to do after you do the wind tunnel testing, but I can't imagine a diffuser doing so much good that a higher cg was offset by it. Plus, if you tilt the tank then the bottom of it acts like a diffuser, that's the whole idea. Wouldn't have the strakes, although I'm sure that they could be added later if that was deemed a priority. Quote Link to comment Share on other sites More sharing options...
johnc Posted December 19, 2006 Author Share Posted December 19, 2006 Wouldn't have the strakes, although I'm sure that they could be added later if that was deemed a priority. Strakes are really not needed in our application. You just need sides to the diffuser. I mounted my Borla muffler vertically on the left side of the fuel cell and the fuel pump/filter frame on the right side had a sheet of CF wire tied to it. I'm sure the whole setup generated about 5 lbs of actual downforce but I felt it made about 50, so I drove faster through the corners. In that sense it worked.

JMortensen Posted December 19, 2006 Share Posted December 19, 2006 Hey John I was looking at some pics on http://www.betamotorsports.com of the fuel cell mount you did for Amir. It looks like you did a full frame, I can't tell if it goes all the way underneath the cell. Was that just to mount the pump and all that, or do you feel that the cell needs to be supported underneath as well? Quote Link to comment Share on other sites More sharing options...
