The Cal-look Lounge

following up on the old 427 SOHC Ford motors that I am now learning about...

Here's a thread dedicated to old, odd race and HP engines from the past...

How about the BRM H16 2997cc? It was basically two flat 8 engines stacked on top of one another, yes two cranks, geared together. This engine can be seen in action in brief footage in Grand Prix movie. It neve was succcessful in F1 racing due to its complexity, its weight and huge vibration issues from 2 cranks, resulting in failed drive geartrains...  I think it made 425hp? 16 pistons.... 64 valves, 8 cams, 2 cranks.....

 :o :o :o :o :o

Offy four cylinder. 441 hp DOHC.

Six in a row:

Makes me want to have another Blue Flame six powered car.

DOHC Model T four banger anyone?  ;D

Offys....... 8)

How about Porsche 771 2.2 liter flat eight? 2.2L....  282hp? How's that for specific output. This motor was used in 907 sports racer and in several hill-climb specials (where it was tuned to make as much as 290hp with clutched fan drive!)

somewhere I have a pic of an Alfa Romeo 4 cylinder DOHC motor, like your typical 2000GTV thing, except it is fed by two OIL PRESSURE DRIVEN turbos..... not exhaust gas driven. I can't come up with a pic right now.... but how wild is that?

I remember an old Hot VW's article talking about a guy mating two "type1" VW motors together "end-to-end" effectively making a 8-cylinder !
Anyone remember if he ever finished it ?
Anyone know where it is today ?
I would have loved to hear it run !
 :o

didn't Emerson Fittipaldi drive a circiut racing Bug with motor as such?  :o

Another BRM motor.... this time a 1.5 liter V16
yes.... 1488cc divided amongst 16 tiny cylinders.
It has been claimed that this was the first 4 stroke motor to ever exceed 10,000 rpm (1950-51)... up to that ponit the Alfetta 159 straight 8's were going 9-9500 (pretty amazing for those long stroke Alfas)
bore x stroke was 49.5 x 48.6mm (!)
2 valves per cyl (31.8mm intake x 27.7mm exh), dohc per head
two stage Rolls Royce roots-type blower, SU carbs, alcohol fuel, 5.7bar boost!
460hp @ 11,000rpm.... from 1488cc in 1951!

Here are some ARDUN FLATHEAD PICTS

How about a cosworth or two

do they have a smiley icon guy with a magnifying glass to choose from above, so I can see those pics? WTF Tony?!!!!!!!!!

There used to be another topic with strange racing engines...  There was a picture + movie of a guy that build a two stroke beetle...   :o  :o
Anybody can find this topic or post the pictures/movie of the engine again here.  That was true art!!

Ok Mr Smart Ass - look i allways seem to do it wrong - WTF  ???  :D :D :D

Found it under pure racing - All you tech guys - may 08 - just dont know to get over to here

If you heard one of these running at full bore, you'd know the true meaning of pain. It is the most ear-shattering engine I've ever heard in my life. Amazing!

I have a sound clip from that engine on my computer. It makes the hair stand up on my back. ;D

Found it on youtube

No hablo Francais

Seen at the NHRA Museum...
Mickey Thompson's Challenger 1.
Four 415ci supercharged engines. It went 406mph circa 1960.

Jay Leno's Collection...
The Rolls Royce engine is either from a plane or a tank - I don't remember.
Leno's crew built a car around it. The car is huge!

L.A. Concours in Pasadena...
1965 Cobra - IDA galore.

Dunkel Brothers Collection...
Just an old Carrera engine.
I like those velocity stack covers!

Jim, you really need to get Practical Performance Car magazine! Last month they looked at radial and rotary piston engines - Junkers JU88 and Focke Wulf FW190 being radial, Le Rhone being the latter. The month before they looked at 2 crank motors, using two pistons per cylinder, a la Rolls Roys K60 Range and Jumo 223 and 224. Oh, and one of the staff writers has put a 27-litre V12 Rolls Royce Meteor engine (the non-supercharged version of the WW2 Spitfire engine out of a tank!) into a Rover SD1... :o

yeah....just....   ::)

The mind boggles! Radial engines huh

see that catch can (though I think it is for coolant on this motor)? I think an oil breather for a VW motor, that mounted on firewall,  centered in front of (towards F of car) fan housing would be very cool. The 356 Carreras had a similar breather tank, and was fed from a big breather off of top of case. Anyway, sorry to get off topic.....let's get back to weird race motors.

this time not a race motor, by any means, but still an odd one.... and a huge one.
Bugatti Type 41 "Royale" straight eight engine.
Bore x stroke: 125mm x 130mm = 12.7 liters
cylinder head and block were machined from one billet, making valve grinds a real chore. 3 valves per cyl.
I think this gentle giant was really underworked, as it made a little under 300hp.
I think a cousin of this Bugatti engine was used in locomotives.... no kidding.

The Schlumpf Museum offers the largest selection of Bugattis in the world, including a couple of 12720cc Royales. They were supposed to reach 200km/h (125mph) - quite an accomplishment.
The museum is quite amazing... Check out this picture.

is that a mirror in the bakground? I remember Car and Driver did a piece on that museum in 1984 I think....  got me going on Bugattis.... well the real ones. Not those rebodied VW's.

No mirror. One room, dozens of killer vintage racecars...
And that's not even showing the Bugattis!

There are 437 cars in the Schlumpf collection !
123 of them are Bugatti's !
 :o

.

How about the Mercedes Benz W196 straight 8 with desmodromic valve gear? (no valve springs)
2500cc
Hirth roller bearing crank, one-piece rods, power-take-off from center gear on crank, mechanical injection, dry sump, I think it made 280hp+ at 9000 rpm, ran on mix of alcohol and benzine. In the mid 50's

The 300SLR famed race car (from 1955 Le Mans tragedy) used larger cc version of same engine....  more info here http://en.wikipedia.org/wiki/Mercedes-Benz_300_SLR

I went on trip to that museum with my dad and Uncle when I was 16 it was the most amazing place I have ever been line after line of bugatti's, Ferrari, Rolls-Royce, Maserati, Maybach, Mercedes and the 2 royales they had on rotating platforms were just incredible.  8)
I found it amazing that the brothers who collected these cars managed to keep it such a secret, it was discovered when the disgruntled workers stormed the factory that the brothers were running (which had gone bump) no body knew they would have the cars brought in, in covered wagons in the dead of night :o

anyway back to the thread hows this for a rare motor a Magee quad cam top fuel motor

Radials? Pah! You need a rotary – and I don't mean a Wankel engine...
(http://www.keveney.com/img/gnome.gif)
To quote:
"Balance. Note that the crankcase and cylinders  revolve in one circle, while the pistons revolve in another, offset circle.  Relative to the engine mounting point, there are no reciprocating parts. This means there's no need for a heavy counterbalance.

Air Cooling. Keeping an engine cool was an ongoing challenge for early engine designers.  Many resorted to heavy water cooling systems.  Air cooling was quite adequate on rotary engines, since the cylinders are always in motion.

No flywheel. The crankcase and cylinders provided more than adequate momentum to smooth out the power pulses, eliminating the need for a heavy flywheel.

All these factors gave rotary engines the best power-to-weight ratio of any configuration at the time, making them ideal for use in fighter planes.  Of course, there were disadvantages as well:   

Gyroscopic effect. A heavy spinning object resists efforts to disturb its orientation (A toy gyroscope demonstrates the effect nicely).  This made the aircraft difficult to maneuver.

Total Loss Oil system.  Centrifugal force throws lubricating oil out after its first trip through the engine.  It was usually castor oil that could be readily combined with the fuel. (The romantic-looking scarf the pilot wore was actually a towel used to wipe the slimy stuff off his goggles!) 

The aircraft's range was thus limited by the amount of oil it could carry as well as fuel.  Most conventional engines continuously re-circulate a relatively small supply of oil."

I know Honda fiddled with a race motor, but not sure if it was GP car or motorcycle, but it was designed with oval bores!

At one time they mounted four V-twin motorcycle engines side to side to create an 8 cylinder GP car !
I have an old magazine article about it somewhere.
 :o

I remember that - wasn't it a 3-litre V8 to go into a motorbike or something daft like that? ???

It was a 750cc V4, worth a fortune nowadays, more here:
