44L inverted V12 .... 3.7L jugs

The massive 44.5 litre Daimler-Benz DB 603 inverted V12 was selected to power the record-setting car. The engine was an increased displacement derivative of the famous DB-601 aircraft engine that powered the Messerschmitt Bf 109 fighter in production at the time. The DB-603 fitted was just the third prototype (V3) engine of this variant and tuned up to 3,000 hp (2,200 kW), roughly twice the power of the Bf 109 or the Supermarine Spitfire. The engine ran on a special mixture of methyl alcohol (63%), benzene (16%), ethanol (12%), acetone (4.4%), nitrobenzene (2.2%), avgas (2%), and ether (0.4%) with MW (methanol-water) injection for charge cooling and as an anti-detonant.

[Dr_C]

I'm proud to have been mentioned together with this company!

Another dedicated guy in my neighbourhood is Thomas Johansson. He is involved in Koenigsegg and the University. You can see some of his projects at Atom racing He made a W9 engine, which looks like a jewel.

 

[bushmechanic]

Thanks for the link Dr_C

direct link to the W9

ATOM racing: W-9 engine

can download his thesis as PDF

W-9 engine design

Ive always liked this engine as it is a real W shape

the Veron claims to be a W config but its not really

 

[bushmechanic]

veyron block

more like a stacked V than a W

 

[bushmechanic]

more goosebumps!

[akshun]

Well neither of them is actually a "w" in the same way a "V" is or they would have two cranks. The veyron design reminds me of the VR6 golf my mate had years ago, was classed as a V6 but looked like a straight six on the outside.

Still loving this thread BTW, keep the good stuff coming!

 

[bushmechanic]

thats a good point Akshun, there is a double cank harley powered thingy somewhere
