Twin engine cars


Recommended Posts

You might be surprised at how many cars have been designed with twin engines, disregarding EV/ICE hybrids.


Here is one of those slideshow type reports listing a number of such examples, many as conversions of popular showroom cars.

More power. More weight. More failure.


If you go through the slide show you will come across a car that entered the Pikes Peak event,  but failed due to a broken zerk fitting. What's a "zerk fitting"?


The patent for the Zerk fitting was granted to Oscar U. Zerk in January 1929. Before Zerk fittings existed, bearings were lubricated in various other ways that tended to be more maintenance-intensive and often provided less effective lubrication.  Often lubricant was delivered under no more pressure than gravity, as with this oiler.


Ball check valves to accept grease supplied under pressure from a grease gun, such as for car and truck chassis lubrication points had been marketed since 1919, both for OEM installations, and for aftermarket upgrade kits which would screw in as replacements for stock grease cups, but Zerk's fitting was an improved style, less vulnerable to dirt and more forgiving of angled approach. Today, many companies make these grease fittings, and the original name is known to very few. Most will simply call it a grease nipple.

How could a broken grease nipple stop you from winning a race? I could understand if was Newcastle Norms FJ Holden, with the chrome plated grease nipples, and double reverse overhead twin cam door handles.

A chrome plated grease nipple going missing would totally wreck your chances of winning a Newcastle drag.

I always remember the story of Stirling Moss on his first visit to NZ, being amazed at the great roads in NZ. Real drivers roads - so he took full advantage of the long straights, and beautiful windy sections with heaps of curves, where he could practice his high speed driving skills, and cornering skills.

Of course, he pretty much ignored the open road speed limits in his pursuit of his driving pleasure (I can't recall what he was driving, but it was a powerful car with excellent handling).


After a couple of hours of thrashing his set of wheels through the glorious countryside and great roads, he became aware of set of flashing blue lights way behind him, trying to catch up with him. He thought he'd better slow down.

So he slowed down, and a NZ copper in a nearly-expiring MkII Ford Zephyr, reeking of major heat buildup, pulled up alongside him, and motioned him to pull over.


The copper who got out was apoplectic, red-faced and fuming. He berated Moss for his reckless and illegal driving, and complete disobeyance of speed limits.

Then the copper said, "Who do you think you are, anyway?? Stirling Moss??"  :cheezy grin:

Moffat ,like Jack Brabham, was easy on cars. Stirling Moss wasn't.   Nev

I’ve seen that.

Mate and I were testing his racebike at Oran Park, sharing track time in 30 minute sessions with cars.

As we stood watching a Torana being thrown around the track, know-all mate was very critical of the lines taken through corners and the rough gear changes.
The car came in to pit and out stepped Stirling Moss, who was preparing to run that XU-1 at Bathurst with Our Jack.
