| 88-Gearbox showing clearance-Here you get an idea of the curve I needed on the bar to get the clearance. It was hard bending that believe me. I need to work out more..

| I'm changing from my original plan of going with a Rover V8 to the BMW V12. Part of this on an injection system requires an output from the petrol tank through the fuel pump and a return. As the BMW has 2 flow and returns (one for each set of 6 cylinders- 2 fuel pumps and filters), my petrol tank needed modifying. Its aluminium so I got a specialist to weld on an extra flow/return nipple. They are different diameters, and not off the shelf so I had to manufacture them myself. Parallel do a slightly larger tank with 2, and I could have swapped, but this involved extra cost and the fill neck comes out of the top in keeping with the 6.0 or GT style filler cap setup. As I'm building an SV and wanted my Aerocap to remain on the side of the wing, it was easier to modify my existing arrangement.

For a while now I've not been happy with the arrangement for holding the radiators in place. On my chassis they are held simply by 2 small bolts on minimal thread via one side of the radiator. To me this is unacceptable and I can see in time a problem developing with this as it was. After visiting Stoneleigh 2006 I noticed Parallel have since started to modify this by adding a rod welded to one of the rails to pick up on one of the bolts on the other side of the radiator. I decided to copy this and also add a 2nd so all 4 possible bolt positions are used. Here is the lower fixing I designed. It picks up te lower offside mounting and uses the inside of the wing, through the rear bumper as a fixing, also adding support for the bumper :-)

| Here is the lower mounting in situ, bolted and sprayed up. Coupled with the additional extra mounting, this makes for a very strong mounting with no play or chance of water leak/cracking. I did this on both sides of course. I may need to put a thin layer of insulation under the mounting at the bumper end if heat transferrance from the radiator becomes and issue, but I suspect it will be fine as is.

| To complete the set up I welded a mounting to fix the top as well. The radiator is still totally removable.

| Following on, as part of my change from Rover V8 to BMW V12, I need to totally remove and replace my orignal engine mounts with a different set up. Here I am taking an angle grinder to my very expensive chassis. Lets hope I don't slip!

| New V12 Setup- With the old V8 mount removed I then welded in the V12 mounting seen here and added a second fuel pump and filter which is required for the dual setup on the BMW engine.

| I also set about rejigging the plumbing to pass the V12 set up and neaten the area. In particular I wanted to pass the water pipes at a 90' angle to miss all the V12 ancillaries when fitted.

| Time to test the engine mounting and clearence by dropping it into the correct position- as I was going to move house this would also make it easier to transport this big lump!
