Mods Face Off Result: RDP Intake
We got our hands on an RDP unit thanks to a member who sent one up the day of the MFO6. It was the first time I had seen one; this unit draws air from down below the engine compartment, thru the hole on the driverside frame. Its filter is mounted down and behind the headlight.
The filter itself appears to be a dry type; that is to say no oiling appeared to be needed. Its pure white and does not contain the steel mesh we're used to seeing. The fact that its a dry type probably means you do not need to service it (confirm that with RDP), which is a good thing as its a bit troublesome to get down and remove the filter from under the car, relative to those that remove from the top side.
The crowd was split on this one; on one hand many liked that it draws air from under the car. Opponents point out that while it might draw air down there, it also draws water and dirt and grime, and if you've removed your bellypan at some point you're probably asking for real trouble. There was also talk about this area being washed with engine bay heat anyway since the cooling fans blow directly down there.
Proponents argued that the true test of this design would be at the track and not the dyno. Unfortunately we were fogged out and were not able to test it at the track.

THE GOOD:
The design. Proponents point to where it draws air from, claiming it is more likely to draw ambient temperature air than other intakes that have their filters inside the engine bay.
The RPD made 12 peak hp and 5 peak trq over baseline on a stock 6.1. That 12 was the biggest gain we saw on this car. On a lightly modded 5.7 it gained 5 peak hp over baseline.
THE BAD:
The design. Opponents claim that mounting a filter down there opens up a world of possible issues with road grime and water. They also claim that its unnecessary when one understands the sheer volume of air we're talking about at speed. Some also claim its not saving anything since the engine's cooling fans circulate hot engine air down there.
It was weird, how the MFO seemed to be being shut out from any RDP intake, anywhere. I can't point to any specifics, but I had the distinct impression we were not welcome to test an RDP unit, regardless of how we acquired it. This feeling was bolstered by the fact that the member who did offer one up demanded total anonymity. I don't know what to do with all that, but its worth pointing out here as it was a real obstacle in even getting our hands on one for test.
The RDP dropped 2 peak trq from baseline on a lightly modded 5.7. This was the largest drop we saw for this car. It also dropped 1 peak hp and 3 peak trq on a lightly modded 6.1

COMMENTS:
RDP has made some extraordinary claims when it comes to their intake. Their website says "You really can't afford NOT to have one of these!" Statements like these have led to quite a bit of speculation since it debut and that speculation has led to ill will in many cases, especially when RDP was asked to submit an intake for test and declined. Well thanks to the member who sent one up, we were able to test it anyway and I must say, all other stuff aside, the numbers speak for themselves. 12 peak hp on a stock SRT was the biggest gain of the event, for any intake on any car. RDP deserves some serious recognition for that accomplishment.
