Post amazingly cool pictures of engines!
Discussion
Perhaps not an amazing engine, but one that not many of you will have seen before.
660cc water cooled two stroke parallel twin.
Fewer than 160 made back in the 1970s.
I inherited it from my Dad. I sold it a couple of years ago because it really wasn't my thing, but it was a beautifully crafted artifact.

Well, well There I was thinking all American engines were pushrods!

OOhh, a Silk 700, Based on the Scott 2 stroke , Would have loved one of those machines..
Anyway, here is my input
The Lamborghini Miura SVJ Jota designed by Bob Wallace, This is the original one, rebuilt after being wrecked in an accident and was displayed at the Lamborghini factory couple of years ago for one of their anniversary openings
The photo was taken in the UK, not Italy


That engine sounded Awesome

This particular engine was designed by Lotus when GM owned them,so its really a british design,although since then the americans have come up with their own designs.I think they have quad cams in some mustangs.
GM did a few projects with Lotus in the 80's and 90's notably the Lotus Carlton,the ZR-1 was the american counterpart,with Corvette working with Lotus power,but GM would not allow the use of 'Lotus' on the car for some reason.
The project was called the LT5 project,i have a theory Lotus used this as an abreviation of LoTu5

A german tractor pulling team has taken a russian diesel,
and converted it to methanol.
Took them a few thousand man-hours to finish, absolute nutters.
Big deal ?
Well, it is a 7cyl. star engine, with 6 stars,
so it is 42cylinders altogether...
Bore: 160mm, stroke 170mm = 143.500 cm³
7 OHC driven by vertical shaft drive,
central valve timing adjustment
4 valve = 168 valves, roller rockers
max.rpm : 2.500 min-1
max torque: ca. 15.000 Nm
power: ~4.500 kW
There is also a BIIIG radial compressor,
fed by the largest butterfly valve I have ever seen in motorsport.
The above figures were with diesel power,
now it is estimated at ~10.000 hp with blown methanol.
It was converted to methanol, they had to fit 42 magnetos,
and 126 spark plugs !!!
This is how it works :

These are picturs from the engine conversion :

The driver, Paul Heistermann, has been european champion several times,
with his former tractor (can bee seen in the photo section),
driven by 4 turbines,so now he needed something different for a change.
In 07, it already proved VERY powerful on the first pulls,

(also some great other engine sights & sounds on there)
Dragonfire will be a strong contender for the 08 championship.
