Did we cover "Might is right"?....
I have been asked a question that I think I know the answer, but am checking here, because I think we may have covered this already, but, its a common belief.
Take two identical cars, one at minimum weight, one at maximum loaded weight, and crash head to head at 50 mph (Or whatever....)
Logic says that the heavier car will "Punt" the lighter car backwards... right?.....
It has more mass, therefore harder to stop.
We did cover this, on the boards, but did Mythbusters do this on a show?.... they crashed identical cars and busted the two 30mph is a 60mph crash, but they didnt do the Might is Right myth.... did they?.....Lugnuts rule etc....

Not quite what you're asking for, but there's a web extra from the "Date Night" cars driving while stuck together myth. The team basically ran a tug of war with their bolted-together test cars, to see if the more powerful engine in the sports car would win out over the less powerful but heavier taxi. :: rummages around on the website :: It's not letting me link directly to the clip, but go here and scroll to the bottom of the page -- it's the "Torque Tug of War" clip. |

I am looking at a Transit Van that some fool genius has put 1,000 hp in....
The tyres on it are huge.
Its also quite heavy.
This reminds me of conversations I had but didnt quite understand at the time about power to weight ratio size of tyres and what works best and how that changes.... this was during my "Wanna go fast" race period.
I always believe more power less weight...
But then getting the power to the tarmac, you need weight, and too light a vehicle, you have no grip at slow speed........
Of course, at high speed you can create downforce, but slower corners sometimes favour heavier cars.

Of course, at high speed you can create downforce, but slower corners sometimes favour heavier cars. two ways to increase your velocity: more ponies or less weight/less drag. Americans have generally subscribed to the more ponies approach with only a nodding association with weight and drag. they have also had an obsession with making things go fast that conventional wisdom says shouldn't. |

Which is why you have "Drag" races and europe do point to point.....
What good a car that can do straight line if it "Misses" the bend at the end, more to the point, it doesn't "Miss" that rock face.
Power without control?....
I have always likes small cars.
Its a kind of clockwork wonder, how much can you get inside that small car, and how much can you embarrass the bigger "Supercars".....
Speaking from experience, as I used to own a Mini that could scare the crud outa things many many more times "Expected" to leave me in the dust?...
I then put in a fuel injection engine and a few other mods, it scared the crud outa ME.......
The thing was bog standard from the outside, with that weathered look, we even welded a fake original exhaust pipe piece inside the end of the new exhaust to make it "look" standard...

Talking of sleepers.... I just witnessed a beast under construction... Its a classic Ford Escort MK1 "Mexico"... Something like this, but in Blue, at the moment.  Anyway, I have seen what he is up to. He just got the wheels back, and is well impressed... they look like standard wheels from that period, but, are wider, to take a more modern tyre.... Its going to be restored as completely original outside, except of course modern laminated screen, proper wind-shield wipers, and a more sturdy bumper, etc... However... inside, he has gone for modern disc brakes all round, HUGE vented Brembo things, modern suspension, 4wd drivetrain, and a complete modern underneath fuel injection engine..... It will all be computer control, of course, .... His reason?.. The last owner blew the engine completely and wrecked the suspension being a twonka. It has to be replaced. Some purists will be all anally retentive about its not a "Real" car any more.. But as he is completely rebuilding the whole underneath to build in strength rigidity and crumple zones to make the whole thing safer, because the floors are rotten and the inner wings are paper thin rust, his thinking was "Quatro", he has taken the whole Audi Quatro road holding ideas and bolted them into place... Hiding that under an old Mk1 body?.... with a bolted on Toyota power plant from something that ran out of road at speed?.. he will have a toyota reliable power and Audi renown road grabbing suspension 4wd drive. I want one of them...Its all sat on his workshop floor whilst he is working out how to bolt it all together... He is a genius mechanic, but I think this thing is beyond me.. I want to drive, but only at my pace, I think it may scare the (BEEP) outa me?... |

there are three ways to deal with making an old car into a driver:
you can pedantically only do it with parts available at the time it was new.
you can do it with only parts designed during its expected service life.
you can make it the best it can be regardless of the source of the parts.
of our two parade engines, one is factory original hardware - with new paint. one has a three year newer motor donated from an expired racing car - but with original paint. it was suggested that the one with original paint should get a 30 year newer Ford 460CID V-8 - or, now that it is too late - the complete drive train and braking system from the first engine I drove for the department.
my Jeep is 100% AMC manufacture - except the flywheel which had to be custom made to match up an engine that had never been bolted up to a manual transmission before.

Now I have a problem....
I was restoring a Mini.
Things have changed, but, even at that time, I had the opportunity to fit upgraded brakes that would stop the thing in half the distance....
I had that argument with a "Purist".
Since then, I have been awkward about restoration of Vintage cars....
I can see no reason to NOT fit retrofit seat belts....
They do some that clip on vis sturdy clips to small unobtrusive mounting points you can attach to strong parts of the car out of sight.
Why not?...
"Because it isnt original".....
Yeah, but its a thousand percent safer in an accident?...
Oh thats not important to the purists?...
I call IDIOT on purists who wont allow and will scorn other people fitting basic safety devices.
I also am not uneasy about fitting safer brakes, or putting a roll cage in where required, and therefore, I am going to be hated by purists...
But I dont seek their company anyway.
The Mini?.. I fitted safer on a lot of things, I even upgraded the seat belts to a wider belt that would cause less serious injury... and I fitted a safety cage roll cage.
I have put a mini on its side before... OK< it was a hoot, but I looked at things different afterwards.
(The Mini survived.. that was the one that got restored?...)

(The Mini survived.. that was the one that got restored?...) like I said - you can make it all original as a museum piece, or you can refit it as what we call "a driver" one of my fellow electricians picked up about a 1920 REO truck for a very short song - because the previous owner had fitted a 350CID V-8 and then become offended when the DMV told him that if he could install a modern engine, he could also install modern seat belts.  this is about what I remember the cab of the truck being like. |
