New '43' Camshaft

While the bonnet was at the bodyshop, GT delivered and fitted one of his '43' profile camshafts. We went through a few duplex camwheels to time it in best, including a re-pro one, which was completely useless, but ended up using the same one as before. Once re-assembled, using the old ignition map it had lost in the bottom end a bit, but after some tweaks of the ignition map it have really come to life, with it coming on cam at around 4k rpm. As the was bonnet at the bodyshop we not been able to take it out onto the main road, but it does seem to pull quite cleanly upto atleast 7k rpm.

While doing the camshaft change I was able to change the engine front plate again, back to a GT6 one, which should give me more space to fit the hoses between the airbox on the engine and the filter box (below the radiator)

Once the parts were back from the bodyshop I was able to take it back over to the rolling road at Maynards to fine tune the ignition map, see what it is doing now and work out what needs to be done next. What we quickly worked out was that the standard silenced I had fitted, 51mm outlet, was only now restricting the engine to about 150bhp. The silencer was soon removed and the remainder of the runs done with out it, this was not a surprise to me as it had always been the plan to go for a larger silencer. So onto the results from the runs;

Power

Torque

The top line of each is the current setup less silencer and the one below with silencer. This makes the best figures so far of 175bhp at 6409rpm and 149lb ft at 5653rpm.
After the silencer there should be more power to be found with a bit more valve lift and a higher compression ratio, but I really need to look at the suspension setup and brakes first.

Fresh paint

I'm a bit out of date again, sorry. A few weeks ago I had a message to tell me the parts I took over a few weeks ago were painted, finished and ready for collection. A few days later I went over with the trailer again to make the collection.

The following day the body, bonnet and chassis was lifted from the trailer, with the bonnet going back onto the car it came from. To make it easier to work around in the workshop, the body was then taken from the chassis and put back onto a wooden frame and to prevent the doors getting damaged, they were also re-hung on the body.
The next job on this body will be to stone chip the wheel arches and fill it up with cavity wax, probably Bilt Hamber's Dynax S50. Not 100% sure what to do with the underside, at the moment it is undersealed, but I'm not keen on the stiff personally. I'd like to paint the inside the new colour before the wax goes in, so there is a bit of paint prep to be done first.
