Would an arc on the outside face of the end plate (to mimic the shape of the wheel arches) make it look more in-keeping, do you suppose?

Crikey that wing is a bit steep, isn't it? What is it from?
Do they know it's missing yet? hehe
They do indeed! It was quite a few years ago now when i was standing in the team workshop, and the spoiler, actually off the "show car" (a fairly std mondeo made up to look externally like the race car for static PR work), was mounted to the wall, and i said to the then Team principal, "hey, that would fit a treat across the back of my rally car!" And the rest, as they say is history ;-)


Co-incidentally, this happened today:

Prodrive HQ gets demolished


eek

Ok, some jobs, like the rear wing are difficult ones, then occasionally, just occasionally, a nice easy one comes along!

Who'd have thought that the mounting bolt spacing on a Skoda Octavia handbrake lever is the exact same spacing as the side mounts of some Sparco race seats?

So, fitting "MOT" handbrake level literally took 1 min ;-)




Wish more jobs were that easy laugh

Nope Banbury!! After quite a few years Prodrive is moving a little bit down the road, still next to the M40, but to a site where they can amalgamate all their resources (excepts the MK composites dept) into one place.

Fans of wonderful "bodges" will love this one:






^^^^^ That's a right royal fudge, to get a digital "crank position signal" out of my Motec M8 ecu! The device uses an LM2903N analogue comparitor as a basic "zero crossing" detector for the VR sensor that feeds in crankshaft position information. Unfortunately, there is no way of getting this data back out of the ecu, so i have fudged in an output line driver that is switched by the output of the existing comparitor. That digital data is then used by my new Knock sensing ecu, that needs accurate crank shaft position to correctly window the knock sensor signal integration. Luckily there was a spare pin on the main IO connnector of the ecu, which happened to be a 5v out, usually used to power sensors etc. So, by simply inserting a push/pull driver, soldered directly to the connector pin, i now have the necessary output ;-) Looks terrible, works nicely.......

Power up the geek drive! Warp factor 9!

You sure do know your stuff, whether it be bodged or not. You can bodge for me any day.

I can follow what's happening, mostly.

I am curious as to if you have the circuit diagram for the Motec or you just followed the input pin across the PCB to the comparator? I'm surprised that they didn't grind the faces off the IC's. We used to do that at a previous employers ECU's before they went out the door.

The M8 is a pretty simple old ecu, and is mostly through hole components, so easy to track signal lines across the pcb. I don't have a schematic, but a quick look around the IC's failed to show any specific VR amplifier (LM1815 etc) so it pretty much had to use a comparitor or schmitt trigger. And, right next to the main processor was a dual channel analogue comparitor, so a quick probe with a scope popped up the requisite data lines straight away!

Max Torque. Got to ask, and don't take this the wrong way please, but I'm sure that you know that doing stuff like this isn't normal. We all love our projects, learning a few new skills and having the chance to own a one off with our own sweat and blood behind the panels.

Some are good at bodywork, engine development or chassis setup. Some are masters of electronics, software or hardware. A tiny minority even understand how gearboxes go together.

No one bloody well knows everything!

So I ask, nicely. Are you an actual genius? You mentioned your work on the p1 (both of..) a work of genius in itself, but with a team behind it. You've done all this by yourself. And I dont understand how.

If this isn't a show of mastery I'm almost afraid to see what is.

I'll agree with the chap above. You're a wizard, harry.

Given how well he knows his way around a PCB, I shall name him Harry Puter.

Go get it scanned somewhere and I'll help you set up a CFD case in OpenFOAM...

That would be nice, but time consuming! (already have too little time ;-)


So, more progress on the wing plates, now with some "profile" to them, although obviously just mdf in primer as patterns for now, and without finalised Radii etc:









Looking OK i think?

(have left enough space to put an active lower flap across that stalls the main wing during braking etc at a later date.........)
