Those of you with a 3.2 with a IPD plenum...how do you like it? As far as recall there seems ti be nice gains to be had on larger displacement engines but I haven't heard of anything definitive with 3.2s and down.

Just some thoughts: The Porsche t-shape conduit would allow intake flow pulses from side to side (or cyl. bank to bank). The IPD being a y looks like it would impede this flow. I am not sure that this is desirable. Any thoughts on this?
