Continued crappy British weather and no garage leaves me with still slow moving 'indoor' work...

Had the air box drawn up in AutoCAD so I have precise measurements and angles to work to, this box is 5.5litres of air, I know the standard Busa box is around 8.5litres, but considering I've seen highly tuned race cars run off the Pipercross PX-600 airboxes which are less than 3litres, I'm happy with the design and size...

This is the box, you will notice that the leading edge is going to be left open altogether, or boxed off with a slot cut into it to marry ups with my bonnet vent, after all, the sole reason for the box is to reduce induction noise...


Slow work but I'm happy with how its taking shape... final polish on the lathe to be done once the holes are drilled and tapped


A far cry from the original 2.2kg chunk lol


12x half inch, or 3/4 inch holes will be drilled in it to aid removal in the future


Mike insisted on smooth boring the inside despite it not being seen lol

Cant see where to post about Brakes... doesn't seem to fall into any particular category - so I will ask the readers of my thread instead lol...

Will brakes that have been removed from an MK Indy with Cortina uprights, fit straight onto my Sierra uprights? or will I have to make some new alloy callipers brackets/ spacers?

Long awaited and slow progress but well worth it, we have a finished custom article, yay!

Decided we didn't like the 'bolted on' look from the steering spacer to the Sierra hub, so we turned out the diameter so the spacer would sit snug 'inside' the Sierra hub


Like so... looks like one unit


Two finished bits


We drilled and tapped 6 holes in the conventional holes if ever I change steering wheels


Total setup, with all bolts 1.673kgs, down from the original 2.485kg, thus saving 812grams, best part of a kilo, but please remember the weight was secondary, and we could have made it with a thinner side wall, but at the end of the day, its steering the damn bathtub! So safety comes first!


Finished look, off the car - because its pissing down again lol

Are you sure it's an Indy with Cortina hubs?
Either way, not a straight swap, but why would you want to?

They're Wilwood 4-pot calipers, 245mm drilled & vented disks and Mintex 1144 that have been removed from Jon Ison's MK Indy with Busa (I think it's an Indy?)

Going new brakes for unsprung weight advantage of alloy calipers, will make up some new brackets then, just wasn't sure of the holes will be in the correct place... :-)

Right, that's different
Std cCortina calipers would have been debatable

Jon here, no it's a locost cortina uprights, as I said when you collected them 99.99999% sure there not a direct fit onto sierra uprights, I would see what rally design want for a set of adaptors, the cortina ones fitted will sell.

Reading your "blog" and the desire to save weight a very small part of one og my wing stays is still on one of the callipers, remove that and a few grams will be lost

Great to meet you btw, shame we didn't have a little more time to chew the fat, put this thread on my watch list.

Hey Jon,

Thanks for dropping in... totally get you regarding fitment and I gave them a good clean up last night with IPA & brake cleaner, noticed a bit of your wingstay is still attached lol

When I bought the at it was already really light, so looking forward to getting it back on the corner scales!

Lack of garage took its toll last night, half way through the night it seems the car cover blew off, and I came out this morning to my MK full of water, proper bathtub stylie...

The seats full of water, floorpan, harnesses, steering wheel soaked as it was sat in the passenger seat awaiting refitting goes without saying everything is soaked considering its not stopped raining

Make sure you have some drain holes in the floor
It dries quicker when you jetwash the inside of the car
Otherwise the rest is remarkably durable, needs to be in this weather

I like the interaction of a forum as that's what it's all about :-)

Colin, yes, it's in his front bedroom sat next to his milling machine lol

I've been following your thread all the way along. I haven't piped up, as although I have the same car a great deal of what you're up to (lathe-work and talk of milling machines) reminds me of my 'engineering workshop theory and practice' O-level in 1965. Since then, I've been a 'pen-pusher' and much of what you're up to is quite frankly, beyond me.
Keep up the good work though. Just because I've nothing to add doesn't mean I'm not interested, (not to mention lost in admiration).
Well done!
Bob.

Looking at the 2nd photo above it looks like you`ve fitted eyelashes to your headlights! Then I realised it`s just the circular bonnet vents in the back ground. Have a look you`ll see what I mean

Firstly would like to apologise to Colin/ ReMan - I said I'd pop over today to lend a hand but I completely forgot, wasn't intentional, intact, I was oblivious until the wife said 'are you not going over Cols anymore...' - Sorry bud! D'oh!

Not much of an update, got the front aero diffuser / splitter powder coated, had it back today


Open under side before and after...




Side on view for those that sent me a message asking for one


Open rear end to let out hot air


Made the centre piece removable for oil changes, and quick fixes


Engine bay look in through OSF


Looking down towards nosecone & rad at front, from standing at passenger side


Offside, side view of flat floor from inside bay




That's all folks!
