a) Width between inner edge of rear chassis rails
b) distance from gearbox beam rear edge to rear box section, behind spare wheel well
c) height and width of torque tube tunnel
d) Diameter of torque tube
e) Distance frm top of rear chassis rail to bottom of inner arch.

  1. 37.75"
  2. 27.5"
  3. This is not so easy...the tunnel is tapered, not straight, and it flairs out at the "bottom"
    1. Total height is approximately 12"
    2. Height from the top of the tunnel to the top of the rear torque tube support bracket is 7"
    3. Height from the top of the tunnel to the bottom of the rear torque tube support bracket is 10"
    4. Width at the top of the tunnel is 4.25"
    5. Width at the top of the rear torque tube bracket (i.e. 7" down) is 5.3125"
    6. Width at the bottom of the rear torque tube bracket (i.e. 10" down) is 5.625"
    7. It then flares out from there and is somewhat irregular along the length of the tunnel

  4. OD of the torque tube is roughly 3.5". I don't have proper calipers, but judging based on the size of the u-bolts used to clamp on the exhaust hangers, I'd say 3.5" is close enough
  5. This isn't so easy either. Firstly, I don't exactly which part of the inner arch you're referring to...it tapers up from the bottom of the rear wheel well back to the bumper. At it's deepest point, the distance from the side frame rails down to the deepest part of the inner arch is ~14". However, the rear frame rail is about 1" lower than the two side rails.
Hope this helps, let me know if you need more. I won't be able to crawl around under the other chassis until tomorrow or Friday.

Dan,

Thats great,i really do appreciate it. i can now make up a set of drawings to see where things will fit.
So by your measurements, there seems to be about 4 to 5 inches above the TT for me to play with.

4 at the most, and don't forget about the shift rods.

Dan,

Only 1 shift rod as i am using the 968 set up. So i think i can squeeze a couple of 32mm alu pipes into the top of the tunnel. BWHAAA, BWHAAAA

what's the capacity of such a fuel cell?
And can you explain what the advantage of such a thing is? I guess it's more safe than a fuel tank, which is good for on the track...

Is it just a box or does it contain some sort of kevlar bag or something?

Capacity is 15 gallons

Advantages are safety, form factor, relocating the fuel tank to accommodate other innovations under the rear deck, and most of all, E85 safe

Update: photo shoot from this weekend's efforts. Many thanks to Mr. Todd Quenneville, fabricator extraordinaire, courtesy of the Pub Racing team

First we decided to complete remove ALL of the material in the rear hatch area. I was originally thinking about retaining the stock muffler mounting location and shield (rear LHS of the car), as well as the lip of the original deck sheet metal which is where all of the stock fuel and brake lines mount. Also, I had cut the main decking out with a recipricating saw, and Todd being the perfectionist he is, wasn't satisfied with leaving all the stock welds and stuff in place. So we got out the sawzall and the spot weld remover and had at it.


The next task was to clean up all the metal to prep for the welding. Todd in action with the flap wheel:


All clean and ready for fabrication to begin:

The sheet metal in the rear frame rails is actually surprisingly thin and flimsy. Since we had plenty of material (48 feet of 1" square tube stock), Todd suggested that we reinforce the frame rails all the way 'round, welding the tube flush with the surface. This will later provide mounting points for Dzus fittings which will be used to secure the aluminum bulkhead that will be installed upon completion. Also, we used some small metal plates, about 3" x 4" x 1/8" steel, as reinforcements on the framerail itself. These were mounted under the lateral reinforcements, and we used these to weld the main fuel cell cage supports.



After the upper reinforcements were tacked in, the plates mounted to the frame rails, and the two lateral main supports were tacked in, we test fit the fuel cell box:


Time to make it permanent. Pull down your welding visor


Next, the cross braces were added in, and time for another test fit of the cell:


We decided not to mount the fuel cell exactly centered, which was my first inclination. However, after conferring with Todd, we decided to mount it as far to the RHS as possible. This accomplishes two primary goals: it will counter balance the driver's weight, and it leaves a perfect space on the LHS for mounting heat shields and a muffler for street use (if desired):

Day two: time to finish the under side of the cage. Visors down!
