I've started to think about the Fiesta again. I've decided to change the wheels to the Mondeo Cosworth type in 7j.

I found a set of the rare RS centre caps on eBay so I now have two sets from which I can make one really good set, and have a couple spare.

The body kit is sprayed and ready to fit so that will be the next task. No further movement until around May because I have other things to finish on the 430 ready for our wedding in June.

Some organisation to get things moving again.

Crankshaft and Engine Build
Today I've been in conversation with Ian with regards a plan for completion of the engine, and I'm going to visit him next weekend to go over it. The bespoke crankshaft came up in conversation and the topic of dynamic balancing and lightening; I've never been particularly happy with the weight of the new crank and always planned to have it optimised then the machined areas re-nitrided. I had a flick through the IKE website and noticed that Ike has changed the design of the crank with the new ones seeming to have a lot more weight reduction machining than mine - compare the photos below

I've fired off a mail to see what was behind the change and if there's anything I need to be aware of. I also spotted a 99mm stroke crank is on offer (mine is 95mm for 2.2)...it may be a step too far for what I want but I'll seek Ian's opinion.

Clutch
I've found a clutch. This was a bit of a sticking point because the usual route for the MTX75 above ~350ft/lb dictates the use of either a Helix or AP Raching sintered paddle clutch, and I really didn't want that having years ago gone that route in another car build. I mentioned in my last update that the later TVRs used an AP Racing twin plate organic clutch with the Ford output shaft size/spline configuration so I sent out a few enquiries with regards torque capacity but alas, no answers received so I started looking elsewhere.

In the end I found what appears to the the perfect solution: TTV produce a twin plate organic clutch rated at 550 lb/ft and an adapter flywheel specifically for the Mk1 Focus RS (the gearbox I'm using). These are reasonably new to the market, so that and given I haven't been close to the Ford scene for a while means I don't know of anyone using them. I was in conversation with Ian today with regards starting the engine build again, and he happens to know the owners and will have a chat with them.

Image

The only consideration is the price: they are more than the expensive (twin plate) clutch in the 430.

Wheels
I've decided to go with the (rare) 7J ET35 Mondeo option wheels. I did buy a set of these earlier on in the project knowing that I always liked them:
Image

Unfortunately one of those is buckled and I'm not particularly keen on having it repaired, so I managed to find a straight replacement which is now on its way
Image

I also purchased one brand new centre cap. Next week I'm going to send the wheels for a blast and good refurb i.e. fine media blast, powder undercoat, powder colour, and paint/lacquer finish -I'll supply one new centre cap so the re-furbishers can match the exact original factory colour.

PetrolTank
I have a friend building a high spec Mk4 Escort RST who would like my WRC Inconel manifold for his build, which is based on a largely WRC spec Zetec. I happen to be taking a different route with the exhaust manifold on my car so it is surplus to requirements. He happens to be a motorsport alloy fabricator for a well-respected company so today we agreed exchange of the manifold for a neatened up alloy version of the mock-up tank I have made. The plan is for two Bosch 044 pumps in the tank, mounted within two collector 'cubes' to prevent surge, in addition to internal baffling. The exhaust cut out will be a diagonal in order to simply the fabrication.
Image

I'll send off my mock-up tank next week.
