Dammit said:I'm far from an expert, but:
- Throttle response, with each throttle butterfly positioned very close to the intake valve, is very sharp
- You can run much lumpier cams than with a single large throttle
- The ITB butterfly is 50mm wide, which gives an area of 19.63cm per throttle, or ~118cm in total
- A single 82mm throttle gives an area of 53cm, less than half that of the ITB's
- They sound awesome
- If you can see them they look extremely cool
- You'd normally run alpha-n with ITB's, rather than have a MAF in the airflow
