Volvo 480 Turbo throttle body size?

[steveT2]

Can anyone confirm the size of the Volvo 480 Turbo TB the one on the Turbo 2 at the mo (the same as it was mapped with in case Scoff is looking)is supposedly from a 480T but the spare 480 T throttle body? is bigger. i think the fitted one is 45mm and the spare is 50mm. which leads to another question?

The Turbo will be getting upgraded over the winter, bearing in mind the cc of the engine (1565) would the larger TB be of any benefit?(after further mapping)

Cheers
Steve

without getting too scientific I'd say:

45mm for <240hp
50mm for <300hp

oh, and 32mm for 120hp, so what do I know
