4.5-litre Daimler V8 upgrades
Hello, having read an old thread on Daimler Dart SP250 V8 upgrades where someone was able to bore and stroke it to 3.3-litres+. Am curious to know if anyone else has managed to do the same with the even rarer 4.5-litre Daimler V8 and has been able to discover its natural displacement limit?
Jaguar at one time was said to have looked at a 290+ hp 5-litre version during the development of the Mk10 before the idea was dismissed when it outperformed the 3.8-litre XK6, yet how much larger could the Daimler V8 have feasibly grown beyond 5-litres? Another fascinating tidbit would be that the true output of the 4.5-litre V8 was actually said to be underestimated by some 30-40 hp, since Daimler's dyno was limited to 220 hp. |

Re: 4.5-litre Daimler V8 upgrades
The Daimler engines fail to capture my imagination because they're both extroardinarily scarce plus also quite heavy for their size. Maybe they could be built-up to great effect... but I think there's a more obvious British V8 that people should be thinking about.
The Rolls Royce (and Bentley) L-series engines were built for 61 years. They're plentiful, relatively affordable, and every part on them is top quality. Aluminum block and heads. Obviously, they're rather large for an MG or a Triumph... but I've always suspected one could be a big upgrade in a Jaguar sedan or XJS. If I were building one, I'd certainly plan on custom fuel injection and crank-fired ignition. Custom cam. Lightened crank? The big question would be blower or turbo. Edited 1 time(s).
