500+bhp Mk3 Fiesta Project
Discussion
Stunning project Mark - I fired an email over to you via PH the other day, did it reach you? (They sometimes get dumped to spam!).
cheers,

All apertures and sills have been taken back to bare metal:
Part way through preparation. The Olive drab and dark Grey areas are remnants of various guide coats.
Other customers' cars: Jaguar XK120, Lotus Elite (I think), Lotus Sunbeam. Out of shot: AC Cobra and Lotus Elan.
The chaps sprayed a colour sample for me. I was happy with the first one.

I went to the body shop today as I'd found some new body kit parts for them to spray, the pieces I'd given them were good second hand items and free from warpage but the mounting studs had suffered their usual demise. The new parts obviously have the studs present and that was precisely the reason I got them; I want to keep the front body kit removable to make removal or (worst case) panel repair easy. The front wings had already been converted to bolt on with that in mind. For the rear arches I will use a bonding agent to prevent the necessity of drilling holes through two skins of fresh metal.
Well, anyway, the car has been painted. The guys at the shop didn't want me to see it because it's only part way through the first stage of buffing. That attitude reassured me they are craftsman, and the finish confirmed it:
It's hard to capture the quality in photos as pretty much any standard of paint job will look half decent under artificial lighting provided it was finished recently. The depth of shine due to multiple coats of lacquer is just superb:
Inside and underneath has been done also. My words to them were "make it perfect and ensure there isn't a square mm of the old colour left":

The management can be easily set to retard ignition based on EGT or knock
Retard based on knock = GoodRetard based on EGT = Bad (very bad!) (retard = later burn = "mean" burn at large chamber volume = less expansion = less work done to piston = more heat flux in the exhaust gas = hotter EGT)
On my port throttled turbo i never managed to get the blend exactly correct between throttle plate angle and plenum pressure load determination, so i made myself a little high speed device that oversamples each intake stroke pressure wave (uses 4 high bandwidth map sensors (1 per runner) and the cam sensor signal to phase lock loop to engine position). This then outputs a psuedo MAP signal that has an superb signal to noise rato (because it only samples during each individual intake event, rather than sampling each runner over 720deg), yet combines this with near instant response due to the lack of plenum volume as a dampener (outputs MAP after every intake event in real time).
This gives the rapid response of a TPS based load determination system with the accuracy of a MAP based one ;-)
PS, the Fiesta is looking ace! ;-)

Ahh, so it does. As explained somewhere here: http://www.clubwrx.net/forums/engine-modifications...Retard based on EGT = Bad (very bad!) (retard = later burn = "mean" burn at large chamber volume = less expansion = less work done to piston = more heat flux in the exhaust gas = hotter EGT)

It's a good job I'm not mapping the thing
That's a very interesting device; so if I understood correctly it provides more accuracy to the management in an individual Throttle Body application? Are there any management systems that employ this?

They're not perfectly local to our parents area but then not a million miles away either. I cannot recommend them highly enough.

Steve from the Bodyshop has just sent some more photos.
I've had an additional hole cut in each door so that I can use a Lexus IS200 door wiring loom boot in addition to the Ford boot/loom. This will allow me to run some audiophile grade speaker wire in isolation from the Ford power wires.
Here are some snaps now everything has another coat of Lacquer. The colour looks quite uninspiring here, but it looks anything but in the flesh:
I'm over the moon with what they have done, and can't wait to pick it up next week. I will take some photos outside with my DSLR

Thank you.
My new Evo X Brake Servo and Master Cylinder arrived this morning. The MC is a Bosch 26mm bore unit and will comfortably manage the front and rear AP calipers that I've chosen.
I may have to modify the Fiesta mounting brackets slightly to give more clearance to the Focus Gearbox, but aside from that it should be a straight-forward modification.

Honestly, this thread never ceases to amaze me. Outstanding attention to detail and fabrication skills.
Once you've finished it's surely going to be one of the best MK3 Fiesta's in the World?!
I can't wait to see the finished article.
No doubt!Once you've finished it's surely going to be one of the best MK3 Fiesta's in the World?!

This thing will be great XD
i'm starting to think it won't be driven in anger tho', the amazing paint, and the perfectness of it all...

To be fare, that's hardly a great accolade, I think he took that crown just by painting it Once you've finished it's surely going to be one of the best MK3 Fiesta's in the World?!

Keep up the good work though OP - fascinating build.
cant wait to see the finished car.

Really looking forward to seeing how this is going to turn out. Amazing job so far. You've definitely built it better than Ford ever intended!
Cheers!It's getting there now:
I will arrange for it to be transported home this week and can look forward to fitting the mountain of new and uprated parts to fit over Christmas.
