Exciting stuff!
Would the carbon pushrods have worked a bit better if the alloy inserts had been knurled to give the carbon a better key onto them?

Seems to be a few mappers out there that say the best 99ron fuel is actually Tesco momentum.
Quite a good vid on YouTube that tests various super unleaded fuels and not only does the momentum have the best knock protection qualities but also provided the highest increase in horsepower over any of the others. V power came second, but was mentioned the fuel can be hit and miss whereas Tesco fuel always seems to be fairly constant in its quality. It is also the only fuel where 99ron is the minimum, and can be on occasion slightly higher octane rating.
Esso 99ron and then bp ultimate were described as only really suitable if nothing else is available. Texaco 99 wasn’t available at the time of the test but I’ve heard it is the same as, or very similar to esso 99

Day 6. Right, where do I start? At the beginning I guess :-) Arrived around noon to see Alex head deep into the PC. Brought 20 litres of 99 Octane with me. A few more things were working; fan, lift pump, twin 044s. After lunch we added fuel and started fixing the numerous leaks. The system has been in and out for around 10 years so there were bound to be some issues, but not the ones I expected. First off we discovered that I have plumbed the Holley lift pump in back to front! Then we found that the Bosch inline filter had fallen apart so a new one was ordered and this arrived within 15 minutes. We were not getting fuel up to the injector rail, but a chase of the fuel lines showed that I had managed to cross the feed and return pipes over. Both are dash 8 with a restrictor in the return so that pressure at the injectors is maintained. I need to remake the flexible connectors over the weekend replacing the 45 degree fittings with straights. One of these was leaking, which is the only issue that wasn't my fault :-) As we couldn't continue with the fuel side we thought that we would try to get oil pressure. Starter spun but didn't engage. Took it out and tested on the floor but still no joy. By this time it was 4.30 so there was time to take it to a local specialist to get it checked. No issues with the starter. He showed me how to test it on the floor and I think that we were doing it wrong. So the problem must be in the wiring somewhere, or tied up with the PDM unit which Alex is having difficulty in getting his head around. To that end we will be contacting a specialist on Monday. So, no engine noises today, hopefully some time next week, stay tuned.

Not heard of big boy filler - I'd go with a quality brand like Evolution rage.
Adding sheets of carbon may not be as strong as a smaller strip of carbon in a 'V' shape to add a rib under the bonnet.

I have tried them all but still prefer P38 and P40 but I thought that I would try this one. Filler is easy to apply and rubs down well. Ribs are stiffer but only locally. My problem is that the whole area in front of the scoop is flexing, apart from along the existing stiffening bar. We shall see as it doesn't need much. There are only two layers of original carbon so it is now 50% thicker :-)

They do a flexible version of that big boy stuff in toolstation, It's stayed in the bumper of my daughters car.

We always map on shell V power then advise customers to use Tesco 99.

Checked out the reinforced clam this morning and the extra layer has done the trick. Clam now weighs 8.3kg but I can live with that.

Day 7 Fitted modified fuel hoses and we have no leaks! Fitted new turbo support. However, it was deemed that this was too rigid so could cause problems. Due to the car's intended use it has been decreed that one isn't actually needed! Oh, well, another 80gms saved :-) Turbo water supply pipes connected. Oil added to engine. Plugs removed for first turn over. This was to check that we have oil pressure, which we do. Getting there, although we still need a PDM specialist to set the PDM up.

Tease ! Waiting with bated breath here. Fingers crossed for you. James Cheers. There are a couple of critical issues that could be a pain. Oil pressure is around 4 bar on turnover so the release valve is stuck. Hopefully when started it will shake loose. If not that will be a pain as the pump is in the sump. The other potential problem are the hydraulic lifters. Having sat for around 15 years we hope that they refill with oil before doing any damage.

Can you use an accusump or similar on a temp basis to get the oil pressure up? Almost want an F1 style oil warmer and pressure system to plug in for first starts like this don't you. Sure all will be well. James

Sure all will be well. James Low oil pressure isn't the problem, it's too much as the release valve is probably stuck due to lack of use. Hopefully it will pop open when engine starts and revs pick up. If not then it is a sump off job. Start up is planned for Thursday.
