| Oct 6, 2016 at 20:18 | comment | added | justinm410 | @Zaid. But the differential change is going to be a function of the volume and the size of the valve opening. Maybe the collective valve opening is larger, but that will just nominally affect responsiveness, not power. Lag is determined by the size of the reservoir versus how quickly it can be filled to pressure, so would be isolated from any effect of the TBs. | |
| Oct 6, 2016 at 20:13 | comment | added | Zaid | @justinm410 I believe the main difference is that with the ITB there is less air volume between the throttle body and intake valve. The chief benefit here is quick throttle response, power gains may or may not occur depending on other factors | |
| Oct 6, 2016 at 20:06 | comment | added | Zaid | I like this answer. ITB's can be a pain to synchronize. I wonder if they would help with turbo lag though, since that is the common complaint associated with non-VGT turbos. | |
| Oct 6, 2016 at 20:04 | comment | added | justinm410 | I don't think this applies well to a turbocharger and I'm not sure I am getting the "wait state". One valve opening with a 30 psi differential vs 8 valves opening with a 30 psi differentials will still have a delay as the pressure differential approaches equilibrium. Lots of high performance cars use a single TB. E63 comes to mind. | |
