| while I am not sure why your car seems to behave like it has additional displacement (I am aware of your JWT 500 cams). At the same time I am far less qualified than yourself to say why...but from looking at 1.5l of displacement on what I believe to be the correct compressor map your results (making no more power past 21psi) don't make sence. What I am at least qualified to do is ask questions and try and get to the bottom of which chart is legitimate. We have been shown conflicting information here today. And for the record, your car and Dee's car have very different configurations so it will be intersting to see how his performs compared to yours. His turbos alone have the GT28R housing (not the T04B) on the compressor and use .64 A/R exhaust housing. Along with having both housings extrude honed, so it won't be anything like an apples to apples comparision and again thats just the differences on the turbocharges alone(as I'm sure you know). Eitherway, thanks for the input and for being as patient as you have been in helping get the bottom of this interesting compressor map saga.
