The ID1000 looks heaps smaller but neally flows 3x more. I sat down with the tuner guy and did the maths and he said the minimum injector I need to run E85 was 880cc so I just stepped up to the ID1000's. Plenty of room to move plus stock idle.

Bundy was doing a CA18 swap, how did it turn out?

With MAF, there is no airflow meter restriction, but there is still a restriction from the MAF sensor, very small in some types of MAF (e.g. Bosch hotwire), but larger in other MAF. I worked on a Nissan GA18DE last week, and it had a fairly obstructive MAF (I'm guessing maybe half what a carby venturi would?) ... Theoretically by using an ECU that does speed-density calculations (like the early OEM ECUs) where no MAF and no MAS is needed, you can have 100% unrestricted intake, however most OEM intakes still used a venturi restriction for various reasons

Bundy was using a traditional throttle, so there is still a significant restriction from the throttle shaft. If you use a flat-side throttle like the A12 works engine there would be zero restriction at full throttle

Bundy did a lot to reduce airflow restriction:
* Remove MAF sensor
* Install larger Throttle Body
* used a throttle body with a much thinner throttle shaft
