I cant beleave we both used exactly the same amount of fuel last weekend,

Jase - almost, new wideband sensor, some tyres and some time on the dyno to get the map right and it is as ready as it is gonna be.

Actually ... scrap that .... plans have changed a little

wideband fitted but we are saving dyno time till after the dry sump set up is fitted at the weekend

Well, where do I start ?

Friday and with Paul and Liz at Kettering hospital and me snowed with work and deadlines, a dry sump tank was needed and neither of us could collect it from Pace Engineering.

We were going to be running a std off the shelf sump tank for speed of install rather than a custom designed tank, which will be an option in the final kit (or so I believe).

So, thanks to Ren and a quick blast down the M11 and the oil tank and some fittings arrived back at mine at about 11pm friday night - cheers Ren :notworthy

Saturday morning and I arrived bright and early at Zen and proceeded to strip everything off the car that wasnt going to be needed or was in the way of the install. This was quite a lot and all of the morning was spent dis-assembling.

( and yes I do know my manifold was blowing

)

Still to come off from that shot were cam belt so that the new water pump tensioner could be fitted along with the Zen adapted oil pump to provide the way into the engine oil system. This also meant that we could keep the oil filter, modine and oil cooler install 100% in the OE place.

Sump and oil pump assembled.

The sump was offered up and pump assembled so that I could start making oil lines. Braided hose and special black anodised fittings from HEL to match the lush black anodised dry sump pan from Zen really stood out and it was starting to take shape. Fire sleeve has since been added to the hoses that go near the headers.

Next was getting drive to the oil pump - this is via a piggyback pulley on one of the idlers on the cambelt. You can see it here after i cut the hole out of the cam cover. Very neat and a nice short belt to the oil pump.

Once the oil system was hooked up in place and other elements rigged to enable us to turn over the oil pump to shoot oil around the engine without turning the engine over. Paul wanted to see how quickly it would circulate oil and what kind of pressure we would see. It works very nicely and gave a VERY healthy psi even at about 2 rpm from a power ratchet attached to the front of the pump. Looking good so far but there was an issue requiring a slightly smaller pulley on the oil pump so the engine wasnt going to fire into life at the weekend afterall. Hey ho.

Paul and Liz kindly offered for me to stay at theirs again and work/finish it on Monday. Thanks :thumb:

Monday was spent getting all the tank, fuel system moved, battery moved and generally getting it all back together awaiting on the new pulley.

The battery was going to move to the rear of the car - but we went for an easy option after seeing what space was left over getting the fuel swirl pot and pump moved from the chassis leg (now occupied by the dry sump oil tank) to the battery area.

This introduces few additional risks from the previous working configuration and Paul and I decided that this was the safest option with only a few days til the final round of Time Attack.

So, fuel lines extended where needed, battery leads moved and extended and new fittings for the swirl pot and pump were done and the fuel system was sealed.

As I said the dry sump oil tank was on the chassis leg we were about 2 inches short of height in that area and the top breather hoses caught on the bonnet - so should make shift 'persuading' and it was in. We have only done a temporary fitting of this tank for the moment - the final fitting will be a lot neater.

So ... there we are ... awaiting on a pulley before the engine can fire. This is being made today so it should be full systems go from then with just the headers to put back on.

Huge thanks to Paul, Liz, Steve Fulbrook, Tim, Ren and Wallis for the help.

Excellent work Dunk and a lovely looking piece of kit. :thumb:

Things like this confirm I made the right decision in getting shot of the Scooby. A few more

Cheers guys... Just fingers crossed that it works tomorrow when I pick up the new pulley for the oil pump.

It has come on leaps and bounds and although power hasnt changed from last year, it is a much quicker car now.

Hoping for 'enough' on sunday to bring home the title. Then try and set my best lap of the track in zero pressure conditions.
