The oil pressure topic morphed into a discussion of top speeds. I have mentioned the following previously but readers go and come.
My standard car managed a rousing 50 mph but this very rapidly fell away. Moving the advance over a large range made little difference except to the noise. A decoke and all was restored for another four thousand miles or so. The car used a lot of oil but was never hopelessly carbonised. Has anyone else noticed this effect? I did not notice it with 37 head or any other make of car. It is hard to figure a cause A complaint years ago was that other cars went worse after a decoke due the lowered cr.
The speedo read somewhat lower than all cars compared so was presumably reasonably accurate. Incidentally few roads are truly flat. I travelled 60 miles north of Wellington most weekends. Most would guess the route as perhaps 40 miles flat, but as sensed by the Seven only 2 actually were.
Curiously, although hill climbing, acceleration etc was much improved top sped with 37 head and SU seemed little altered, although with a tail wind it would mange 60 and I was pulled over for this. (I was too surprised to insist on a ticket!) No other car sampled, including employer’s, ever required the skill or produced adrenalin like the Seven at speed, so I have never been lured by supposed high performance cars!
Many contemporary road tests struggled to much exceed 45 mph. However many would be running SAE50 in cold conditions, and were not bored oversize as most are now with associated cc and cr increase.

Reducing camber of rear springs |

I would like to lower the back of my GE Cup by a few inches as it sits a bit high at the moment and I think this will improve the appearance and handling. Doing this would reduce the available suspension travel but I’m not planning to do any trials so I think I can live with that.
The question is whether to have some early type springs made up with reduced camber (say 3”), or just to use Ruby springs which I think have a 2½” camber as standard.
I imagine Ruby springs would make the suspension quite stiff which might be good if there is limited travel. Does anyone have experience of using the later springs on a relatively light early car? Will they fit into the ends of the chassis rails without modification? Are there any other issues watch out for (like the axle oil pouring out of the front of the torque tube due to the change in angle?)...

does anyone out there have a rear window frame for a pearl cabriolet available for sale,I have just acquired a very original but "scruffy"! car running and driving plus as a bonus it stops very well .There is no rot anywhere and the original interior is very usable and will be preserved it has had a new hood at sometime and I think that was when it lost its window. could any owner of a pearl post the size of the frame and the height it sits from the top of the body best regards Rob.
