With a big cam and TB's it not a nice feeling to find an inconsistent brake pedal.

Many thanks for the advice regarding the brake vacuum gents, much appreciated.

John Eales has included a take off from a single inlet port on the manifold, but that design was based on the H234 camshaft, the camshaft that is fitted in it now is a TVR 377. It is not a cam I have heard of before but according to Dom it is a 'huge' cam and the same ones fitted the the 4.5 Tuscan Challenge cars.

Jody will be removing the redundant carbon canister so I will keep this space free for the electronic servo if / when I need one fitting.

In other news the project is progressing. The car now has an engine fitted.

I've just seen your sump pictures. I had a Gp A big wing sump on a turbo engine once. It had the trap door arrangement as well as a spring loaded oil pick up that sat in the central chamber. It held a huge amount of oil due to the wings and ran a bit on the cool side temperature wise due to the oil cooler and to much oil. I had to remove the cooler in the end.

I like the way all the oil's directed to the centre section. just what you want.

I was very impressed by the sump, massively over engineered for my modest needs. I am having the Speed 6 Laminova (oil water heat exchanger) fitted so this will hopefully help bring the oil up to temperature quickly and keep the oil cool. I have an upgraded 4 core ACT aluminium radiator so hopefully there will be extra cooling capacity in the the water cooling system to also cool the oil.

Apologies for the lack of updates, I work for the NHS so I have been absolutely snowed under as of late.

Electronic water pump and Speed Six water / oil heat exchanger sighted


Swirl tank modified, custom bracket made for PAS reservoir, aeroquip fuel hoses installed on fuel rails. Mocal Oil catch can sighted. Replacement swirl tank made from alloy is on order



The fuel lines that run from the fuel pump to the fuel rail have been replaced. The old ones where not in great shape, The fuel pump has been replaced with a pump from a TVR Cerbera which has increased flow rate over the standard Griffith version.


ITG filters installed, igintion leads installed, EWP, catch can custom brackets made and mounted.



Carbon Canister removed, washer bottle mounted on rear of access panel, filler nosel and cap 3D printed




Bracket 3D printed for MBE ECU screen. AFR gauge fitted.


The car has been collected from Jody at Python Racing and is now back at Powers Performance for final commissioning and ECU mapping.

Fantastic.
That MBE screen is an excellent drivers tool and warning device.

Word of warning if I may.
It is never a good idea to cable tie ignition cables together which is why divided clips are available.

However, on the RV8 engine cylinders 5 and 7 are next to each other in the firing order so it is doubly important to keep them apart or they will cross fire.

How can they crossfire if the ignition leads have the correct insulation?

That very same warning appears in the official Land Rovet V8 Discovery workshop manual, as for insulation I have no idea, but presumably at some stage it has caused a problem.

They occasionally break down with age. Separating them just pre-empts this.
