SPOILER ALERT
Engine Masters show on the Motor Trend channel (David Freiberger and Steve Dulcich) did a dyno test shoot-out on a few Magnum intakes with some interesting results. Test was done on a stock 5.9 with a SMALL hydraulic roller replacement cam and 1 7/8 long tube headers. They tested a stock kegger, a well modified one, the modded one with a larger throttle body, a carbed M1 dual plane, and an RPM Air Gap with various spacer combinations. My impressions of the results from the modded kegger were way less optimistic than theirs were, and not much better with the bigger throttle body results. IMO they pretty much confirmed that the kegger intake is a truck engine intake with limited potential. It wasn't until the put on the (out of production) carbureted M1 dual plane that it showed what I would consider a power increase that you would realistically feel, and the RPM Air Gap showed a reasonably decent gain about to what a stock Hemi is rated at. Now for the spoiler, and these numbers are directly taken from the Motor Trend/Engine Masters show. Stock kegger hp/tq (at flywheel) was 403/326, modded kegger 412/330, modded with big t/b was 414/337. The modded kegger didn't really help or hurt it anywhere in the power range - just SLIGHTLY better through the whole range. The carbed M1 at 410/350 started showing a little promise, and finally (what I consider decent results) with the Air Gap at a best tq of 425 and hp at 365, depending on spacer choice - a best of +20 tq and 40 hp over a stock kegger.
I think it would be interesting to see if a little bigger cam or a little head work would help the kegger, but since the carbed intakes showed better results, I still see an issue with the keggers airflow.
In any case - here's the link to the show if you choose to want to watch it. But like I said - not sure their enthusiasm matched the results I saw, or again, IMO - what you would feel. https://www.motortrendondemand.com/detail/59-magnum-intake-shootout/3863266/
