JohnCh Posted August 25, 2023 Share Posted August 25, 2023 Someone on the USA2005 tour had Caterham fitted with this engine. 2.4L, 400hp, 10k rpm. It sounded like a Cosworth DFV whenever he took off. -John 2 1 Link to comment Share on other sites More sharing options...
panamericano Posted August 25, 2023 Share Posted August 25, 2023 Who knows what these V8s are? I guess the first might be Rover/BOP? Link to comment Share on other sites More sharing options...
S1Steve Posted August 25, 2023 Share Posted August 25, 2023 Holy Cow that’s awesome. Pretty light on details, but the cylinder head looks similar to the engine in a Radical Sports Racer. I’m sure one would have to up the driving skills to handle this beast…. Link to comment Share on other sites More sharing options...

The engine was used in special versions of the Levante, Ariel Atom, and the Radical and available as a crate engine in the day. There was a 2.0L, 2.4L, and a supercharged variants and it was stupidly light. 200lb? Hartley did (does?) something similar, although I believe he built them around Hayabusa heads.

DavidL Posted August 26, 2023 Share Posted August 26, 2023 (edited) there is also the Hartley H1 V8 made from two Hayabusa engines. Custom machined block, Hayabusa heads but first test fit was in a Caterham (This is probably the same as the blue car above with the red heads): https://www.h1v8.com/page/page/1562068.htm https://www.h1v8.com/page/page/1821906.htm and the Caterham on a chassis dyno, wait to the end to hear ~10k rpm! https://www.h1v8.com/page/page/4553428.htm Cheers..

As mentioned earlier, it uses Yamaha 5-valve heads vs. the Hartley's Hayabusa heads. Similar in concept, just as nuts, and sounds just as fantastic, but not the same.

Croc Posted August 26, 2023 Share Posted August 26, 2023 And then there is the Prototipo Synergy V8 out of NZ. Only costs NZ$70K (about US$35-40K) https://www.prototipo.co.nz/projects An Article here with more detail since the Prototipo website is pretty sparse. https://www.motortrend.com/features/1511-2014-subaru-brz-jun-auto-synergy-v8/ The problems with all of these V8s was the same: 1) Power delivery was hard to make work in a se7en 2) Gearbox was always going to be a weak link - allow for one a year 3) They have higher than regular refresh cycles and its not as if you can take it to your local mechanic to rebuild. Figure every 3-5 years RST has been wound up although Russell Savory has founded a new company called Motopower. Not sure if all the bits to support the RSTV8 and V6 are still available. While Hartley is still around and one of their V8s has been installed in a Caterham (and road registered!), back in 2017 it took repeated phone calls before I could chat on buying an engine and even then the questions around intellectual property, should the owner pass away or company go under, were never resolved. My lesson was these V8s were a performance dead end. My research in 2017-19 was the Millington I4 options were a long way better than any of these V8 engines. Sensational engines but require more care and attention than our regular street based engines. They are also a challenge to get in and out of the USA with customs being what they are. They are also not street legal. https://www.millingtonengines.co.uk/ Link to comment Share on other sites More sharing options...

CarlB Posted August 28, 2023 Share Posted August 28, 2023 If we want to talk about V-8s for Caterhams, I have a different one that isn't as cool as some of those mentioned but might actually work. Yamaha built an engine for Volvo with a 60-degree bank angle. It has been used in those very reliable Nobles, but I wouldn't blame that on the engine. It is reported on that always reliable site Wikipedia to weigh 416 lbs. The engine was used in Australian super cars maybe Croc can fill us in. Yamaha now builds a 425 HP version for an outboard motor. This engine is direct injected and has a 12 to 1 compression ratio. The fuel requirement is 89 Octane.
