Will the second throttle body also create heat when installed on the inlet of the PD blower? What about cavitation?I tried just one before the charger, read post 138. It didn't go well...
The tb at the charger is there only to limit airflow to the charger at idle and part throttle cruising so it does not constantly try to make boost. It's positive displacement so the bypassed air gets hot. With two tb this will fix the issue.
I also have a bypass hooked up, the second tb was just to reduce noise and drag at part throttle and idleWill the second throttle body also create heat when installed on the inlet of the PD blower? What about cavitation?
I've seen quite a bit of behind the scenes R&D that has been done with centrifugal blowers and an application like this and the results were not favorable for an installation like this. Theory being: the unrestricted air flow on the inlet of the blower will use cool air to decrease inlet temperatures of compressed air. The bypass valve after the compressor is what moves that amount of air through the volute to keep the charge temps cooler. Am I wrong in assuming this would apply to PD blowers as well?
I ask only because I'm curious. It looks like I'll be reading 12 pages to get caught up here
I would still think that the second throttle body would be counter productive? It certainly does quite the system down some but at what cost? Is there an appreciable difference in throttle response? The car is also very lean from what I've seen in the last video, is this a tuning issue or air flow problem? Again, I am curious more than anythingI also have a bypass hooked up, the second tb was just to reduce noise and drag at part throttle and idle
