There seems to be a lot of engineers who have noticed flaws in the design. Can I nominate myself to be the PH team to tackle the speed maybe aim for 100mph. What about filling the chassis tubes with concrete?
Just running shrouded disc-type wheels and changing the suspension to a single faired in arm would probably get you there.

It's a tad obvious having an all female expert team this week. Has channel 4 got quotas to hit, I can't recall a single woman previously. Must add it's great showing women engineers/sportswomen but just really obvious in this episode.
They got a bloke in at the end to make sure it was alright...Loved that both Guy and the French bird were grinning about tbe crash while everyone else was flapping. Remember folks, it's not live. The crash might have been genuine and edited for drama.
Good TV again (and better than last week's) and Guy had me laughing throughout 
He'd certainly made an impression on Helene too, and possibly the others.
A few things, though:
Was the start really that critical on that course (the European equivalent of Pikes Peak)? If so, the 2 bobsleighers might have been handy rather than the engineers in their civvies....
Why wasn't Guy sat further forward between the axles? There were no rear wheel drive traction issues.
Would baffled water bags or weight racks in the 4 corners have been better as ballast?
Could they have reduced the height a bit further, with a longer tail section?
Why not aero wheels or have them faired-in?
I assume that they were using the suspension(? I wasn't sure if it was rigid or spring) adjusters to trim the geometry: ride height, balance, camber, toe etc.
There was a better balance of "science" and entertainment than the hovercraft episode that would have been informative to many.
Why was the engineering bloke only re-introduced near the end? I assume that he had actually been involved earlier.

I Wondered if the concerned words of the engineer as he set off had been added-in afterwards. Guy didn't seem to concerned afterwards (his crashes into the bales earlier on were more dodgy) and Helene went and sat with him on the crash barrier.MC Bodge said:

Given he had to brake a bit at the first bend? Not really. Probably could have just rolled down.PhillipM said:

That's what I noticed. They could have just started a bit higher up anyway if more speed before the straight would have helped.Edit: A drive up Mont Ventoux is on my to-do list.

I thought that. You can only go round a corner as fast as the tyres allow. Be it the first corner or one further down. If you have to brake down to that speed before the measured section, the push start is irrelevant.Good episode though, better than the hovercraft one.
Best one this series, I really enjoyed that. A shame it was totalled at the end as it would have been good to have a go on the same stretch the guy in America did it on or something, but the crash proved how tough the chassis design was.
I liked the Pike's Peak episode, but this one was class. Hovercraft one was the biggest disappointment for me, as I was looking forward to it and it all just seemed a bit mickey-mouse by the end. You could tell he'd decided to pull out as the whole operation looked a bit shaky, and if Guy Martin decides to call it a day, it's probably fair to say most people would!
I wonder if he got with that French bird?

Here we go again. Moan, moan, moan.
The best thing to have been on TV in ages and its being picked to pieces.
Another great fun episode.
Nice one Guy & Channel 4!
This. I commented, then went back and read what others thought - we've got a shower of wet weekends in here haven't we?! I look forward to seeing all your efforts. Oh, and when you hire a voice-over guy, get the one who just gives facts. No charisma or sense of excitement, just words. We don't want to make it seem a bigger deal than it is, do we? I mean what are we trying to do? Entertain people?!The best thing to have been on TV in ages and its being picked to pieces.

FFS.
Love this sort of tv.
question:- would the tourmalet (WEST side) not have served as a better descent? Some lovely long downhill sections. Would be interesting to know why this was dismissed.
edited: West side coming down past Bareges, not east side.

I just thought that! That explanation was at best, ropey, and at worse, wrong.
And if that's Shef Hallam universitys chassis, then they're getting a 3rd - all the rose joints are in shear!
I take it you meant single shear.And if that's Shef Hallam universitys chassis, then they're getting a 3rd - all the rose joints are in shear!
Don't go looking at a 70's F1 car then, quite a lot of the joints at the upright are in single shear. So long as they are sized appropriately they have no issue running in that configuration. Double shear joints at the uprights only really became essential in the late 70's when tyre grip increased enough to cause bending loads beyond single shear capacity of a sensibly sized joint. No doubt double shear mounting is more favourable, but if a simple design is required you can get away with single sheer load bearing joints, plenty of F1 world championships have been won with that config in certain places on the car.
I doubt there was much load from those tyres on the joints, it looked like the wheels flexed more under side loads in cornering than would worry a joint at half the size they used.
The loads involved on a small gravity racer in cornering or bumps are not going to be huge. Not quite the same, obviously, but look how simple and light traditional steel or Aluminium road bicycles with spoked wheels are.
The strength in the safety cage was presumably good, as everything was contained, although Guy's helmet took a bit of a scraping!
I don't quite understand the people who think that it is wrong to comment on and discuss the programme.
