Ok guys, rather than hijack Vipergts's Thread lets discuss on here. Why can you get more power from a triple twin choke set-up than twin SUs? If a good L series will give 250bhp on triples what would be lost on SUs? Surely both types of carb can be tuned to give the correct mixture throughout the rev-range so is it just the air-flow restrictions of 2 chokes rather than 6? Why can't 3 SUs work, thus giving 3 chokes? Is it to do with firing order and which cylinders are sharing each carb? After all Jags and Healeys use 3 carbs. Who on here wouldn't fit SUs because they don't look as sporty as triples? Who would prefer to fit SUs if they were available 'off the shelf'? From a personal viewpoint I have stuck with my 2" SUs because Kevin Irons (who built my engine) suggested I stick with them. He took them away with manifolds (for opening up to match the carbs) and had them reconditioned for me. They have been great but are 45 years old now. If I could guarantee getting another 10 - 15 bhp by fitting triples I might consider it but that would cost about a grand as far as I know. For comparison I would love to try my carbs on a similar spec engine currently using triples (or visa-versa) . Yes I know they wouldn't be perfectly matched but it would be very interesting.
