if 6061 Aluminium is used
I'm sure I read many years ago that the pedals were machined from titanium.That would explain having to add a little bulk though. Thanks.
Another design engineer here! If you havent already, get yourself a 3D Conexxion space mouse. Will take you a couple of days to really get used to it, but will increase your productivity by around 1/3!
On the brake pedal, it's worth noting that most people can exert thier bodyweight in force on the pedal, however, a proper racing driver can exert about 160kgs of force, pressing against the back of the seat....

tia... might start ww3 if we start this discussion....

On a road car on road tyres, I'd rather the pedal yielded at those kind of forces than putting 800kg (5:1 pedal ratio) through the lugs on the brake master then into a very small area in the middle of the front bulkhead, which will be supporting most of the front suspension and steering rack. On a single seated with slicks and aero and a dedicated small bulkhead it might seem more of a consideration. Surely?

So the mclaren f1 wasnt designed to be driven absolutely flat out on track, on slicks by a professional racing driver?On a single seated with slicks and aero and a dedicated small bulkhead it might seem more of a consideration. Surely?
In any case, the brake pedal is floor mounted by (what looks like) 4 x M6 fixings, probably into a machined bracket supported on the underside of the panel. Failing that, it might be bolted into an insert in the carbon. 4x M6 high tensile is more than enough in shear, very little peel in that scenario, so the danger stripping the threads is minimal. Plus that massive through pin is in double shear too, so thats more than man enough...

I have a spacemouse at work I hardly use, I just couldn't get into the habit of using it and therefore never got better at it than what I could do with my mouse. I had used CAD for around 5 years before I got it though. But definitely worth trying especially if the OP is fairly new to CAD. But maybe see if one can be borrowed before dropping the cash on it.On the brake pedal, it's worth noting that most people can exert thier bodyweight in force on the pedal, however, a proper racing driver can exert about 160kgs of force, pressing against the back of the seat....

I've been using CAD for 20yrs now (if you could call CADDS5 CAD!) and my space mouse for 20 of those.
Genuinely feels like someone has cut my left arm off if I don't have it.
Some of my colleagues are like that. I think it depends what you are used to. I do have a cadmouse as having the three proper buttons is waaay better than clicking the wheel on a normal mouse, but although I do think the 3d mouse is the best way I didn't pick it up early enough so never got used to it.Genuinely feels like someone has cut my left arm off if I don't have it.

I would love to see any progress since the last post!
So would I! but moving workshops and focussing on getting my TVR on the road has meant not a great deal has happened since! I'm currently working on the front bulkhead, will post some updates in the next couple of days!
Very interesting project, I'm keen to see your work on this. I'm another design engineer here, I do Solidworks too (instrumentation assemblies so no serious mechanics).
I don't think I could tackle this personally, after spending 8 hours a day staring at the screens in the office I like give computers a miss when I'm at home...

Although the McLaren F1 was probably designed on Catia in the first place, at least that is what the race team used for all their drawing work so I doubt the road car at the time was any different.
GM famously hated 3D CAD - the outline work was drawn up full scale, manually. Though I'm fairly sure they used Catia V4 for component drawings. Fun project, and a good way to practice your CAD. I'd argue that it'd be even better practice to design something new.

This sounds intriguing.
If ever this project gets to the stage where a real car can be built, a suitable engine might be the BMW N73, as found in the E65 760i and Rolls-Royce Phantom. Even the long-stroke Rolls engine should be good for 9000rpm if pushed to just under 5000 feet per minute mean piston speed, and the 760i could go to 9600rpm... assuming power scales linearly to rpm, the 6.0 could make 700bhp at redline. The 6.75 could make about 760bhp at 9000rpm. Or you could build a Franken-N73 6.4 using the Rolls big-bore block and 760i crank to make 750bhp at 9600rpm. Might take a bit more compression and more aggressive cams to make such power though - and I know that, in practice, engines rarely make power all the way to redline. Even so, a pretty conservative 700bhp should be attainable. It's also a bit lighter than the S70/2 - that's 274kg, the N73 is 240kg.
Have always been interested in the differences between the Mclaren v12 and the E65 N73 v12 on the face of it they are very similar. I bought an E65 and have driven it regularly for over 4 years the reason for buying it am not keen on turbos and this as the F1 v12 js a normally aspirated engine and felt this would probably be the last. the engine makes power without turbos though it feels there is one, It is a great car to drive and wish i could afford to keep it forever. Thank you for your piece although a year ago

I haven't forgotten this!
This mammoth task had to go on the backburner for a couple of years.
I spent a year commuting for 5 hours a day.
I got a puppy.
I finally got my own home with my other half. (lots of sorting that out).
I left my job at JLR and started this in August: https://www.pistonheads.com/gassing/topic.asp?h=0&f=92&t=1757185
https://www.facebook.com/AlexWheatleyAutomotiveEngineer/
The above is all going well and I've finally got some stability and time to revisit old projects!
Reading back really reignited my passion for this project (thats the point of these threads for me) and my love of the McLaren f1 hasn't wained 1 bit! If anyone hasn't seen this yet, you should... https://www.youtube.com/watch?v=EkYVXIWAPnc&t=2s
I think I'll slightly change my focus with a view to actually making the bits/assemblies as I go - but primarily still be CAD focussed, I really need to develop my skills. Some bits i'll just fabricate though.
I'm not promising fast progress. Just some progress.
