The bottom line is that unless you replace the hose after the intake, you have not gotten rid of the main flow restriction.

The APS intake is quite nice, but once its tuned there is no real difference in power.

The heat difference between air in the fendor and air under the hood is very slight... even more so when the car is moving, and the best thing is to provide as easy of an intake path as possible for the turbo to suck air into itself.

The overall post intercooler temps seem to be almost no different with a CAI vs a short ram or the stock box. I feel there is no reason to push the development of a much larger intake if we are still stuck with the main restriction in the inlet path which is the stock inlet hose. Replace that, and you might see some good gains, but you still have the next restriction which is the inlet size on the turbo.

The best bet is to convert to a MAP based system, and run a straight (but short pipe) off of a much larger tubine inlet, that has been moved to allow for a full 3 inch pipe to fit. As for that, you bet i am working on it... but it has very little application to both unichip customers or those that want "bolt-on" turbo chargers.
