Vast Intake Manifold

Wanted to know if anyone is a testament to the performance factor of the ported and polished intake. Was thinking about doing it but wanted a first hand review. Thanks for your input

Anytime you deal with porting of intake or exhaust components, you should keep in mind that the airflow through this device will be relative to throttle response and/or lag. If you have a large turbo setup and the intake manifold is a limiting factor, you could possibly reap a fair amount of top end flow from some port work.

For a K03 powered car, I personally would keep the stock intake manifold so that the turbos would spool quickly. Opening the ports will create a bottleneck (when it funnels down into the heads) and slow airflow as it hits the bottleneck. You would effectively increase lag in a trade for top end flow. The problem here is that the K03 has no top end flow. After 5K RPMs the K03 are on the downslope.

Also, for a car driven on the street, it would be much more enjoyable to have the quick boost response to zip through the gears around town. If your car was a drag car or used on a road course, you would make better use of the top end flow (also considering you had larger turbos to make that additional airflow at the upper RPMs).
