Incredible they have so much faith in the centre lock nut going on without cross threading. Still 1.91 seconds is incredible and shows you how much they must practise that repetative movement to nail it every time. If you look the gun is almost pushing the wheel on as it engages on the hub. Quite incredible.

Can that be real?! That would surely ruin the chassis

Count Rossi's road-legal Porsche 917K.....

I'm going to break the mould and say that I like it. -
This was some years ago in japan if I remember correctly. They were racing and ended up crashing in to one another
-
Brilliant . Good to see even the more mature people there having a laugh.

That's an incredible example of stress raisers (unintended) and a significant sheer face on that shaft. Takes a huge amount of energy to do that

Rudi Adams #74 BMW Crashes into pit wall....
adam_r replied to Tony's topic in Car Related Photos/Videos
Surely slamming on the brakes would have flipped it back? -
Well if your going on a track day.......

Great effort! -
It is how to lower your car if you want to go silly low. Stupid imho

Boston Dynamics: New Robots Now Fight Back.

Those guys must be great to work with. Work hard, make serious sh!t, then have a good laugh over it! I wonder how much they cost to run as a business as its still a very niche market and their sales must be limited still -
BMW demand full payment of modified M4....
adam_r replied to Tony's topic in Car Related Photos/Videos
The guy is a tool to think it's his car whilst only paying finance . Watching some of his other videos it seems he likes going in fast modified cars and tries to be a bit gangsta... -
Glad you found the clutch issue and it was relatively easy to fix. What are those chunks of metal from though?
-
Holy sheit!!! I'm amazed that didn't crash on the way!!! Being rwd and the camber, toe and.. Well everything being wrong.. I bet that was a handful on the roads!

Tony. No affiliation with these guys and there is lots more info available online. https://www.enginelabs.com/engine-tech/exhaust/performance-exhaust-system-design-and-theory/

Certainly does Tony. Car manufacturers don't care, but if your chasing performance it certainly does

Helps ensure that the spool is smoother and more efficient. What's better.. One big blow every revolution or 1 smaller more efficient blow every 1/4 turn. Also the negative pressure after each exhaust pulse is still extant up the to point of the pipes meeting. So even though there is now a giant spinny thing in the way.. You can still gain efficiency by tuning and matching the exhaust lengths
-
Tony. Not to do with exit pressure.. First consider this is a 4-2-1 exhaust manifold and Consider the exhaust gas from each cylinder to be a set body size.. I. E a 2 inch glug traveling down the pipe. As that glug of exhaust gas exist the cumustion chamber and starts heading down the pipe it creates a mini vacuum behind it. After a known time period (will cover this in a moment) the glug gets to the exhaust section where it joins I. E. The first 2-1... As this exhaust gas glug merges with the other joining pipe that vacuum is shared with both header pipes. At exactly the moment this occurs, the exhaust valves from the other pipe opens. This means that the sudden mini vaccum 'sucks' the exhaust gasses out the cylinder a bit quicker than normal. There is a significant amount of information about tuned exhaust pipes and it is incredible how critical gas flow is. If this is in to a turbo, then having eqaul length pipes allows a smoother turbo spool and is less likely to suffer with minor boost fluctuations. However you only need to worry about this if your chasing high and reliable power

So how did he take the picture?......

It's not a mirror. Two people pushing hands together with a 3rd person taking a blurred photo -
You guys need to see this on YouTube then... Some absolute corkers on there! https://www.youtube.com/user/yovo68

Good job there. I remember way back when we had a meet at WIM. A customers tyres was very similar
-
That's metal Tony.... Looks like the turret has fatigued and failed due to overly stiff suspension or a they hit a big pothole and the chassis could not cope with the impact
-
It sounds like an everlasting fart........
adam_r replied to Tony's topic in Car Related Photos/Videos
Yes.. So little power requires an awful lot of skill to keep it going! -

That's like the tesla model 3 boot issue. If it's wet the water runs straight off the rear window in to the boot

Gorgeous cars aren't they.
