Default Vortex Rammer: unusual question

Hi,

I have the Vortex Rammer air box on my car as purchased from a previous owner. It has a clear plastic "scoop" piece that hangs down into the radiator cavity. It also has a plastic box piece that over the filter that closes over a hole cut in the fan shroud.

Question: will the Rammer work if I remove the "scoop" piece? I want to add an oil cooler and the heat exchanger will sit right there over the radiator in that same cavity. I can't see how it would fit with the scoop there--the two would occupy the same space.

Has anyone tried this? Will the engine still ingest enough air through the filter direct from the rad cavity with no scoop to help?

Thanks

Kinda defeats the purpose of the design. If you are going to remove the clear plastic box, you might as well run any open element type filter.

My vortex intake is currently installed without the lower scoop portion, just the upper clear box with the hole for filter. It certainly still gives more power than stock as any open filter will make a noticeable over the restrictive stock air box.

The vortex's upper box prevents the filter from drawing in air from the engine compartment which is warmer than the air in front of the radiator. The lower scoop is there to promote a ram air effect, but it is debatable as to whether or not there's any such effect in reality.

I say ditch the scoop. Not worth the time or money to mess around with your intake setup any more than that as I doubt there would be any significant gains to be had.

This sounds good--how long have you been running it like that? Any 1/4mi or dyno to support how the rammer is working without its scoop? I just was not sure without the scope if the motor would get enough air from that area. I suppose the engine will pull some vacuum so it should suck in the air it needs to some degree.

I know I could take out the upper box too but as you said then the element draws in some hot engine compartment air, plus if it rains (daily driver here) I still have that hole in my shroud which now allows water into the engine compartment.

Thanks

No 1/4 mile or dyno, just SOTP. But you can't measure ram air effect on a dyno anyway as the car isn't moving to create the effect and the fans typically used to give the radiator some air don't push as much air as the car gets at speed.

The air intake could be anywhere in the engine compartment, and it will run provided the filter is not obstructed. How cool the air is drawn into the engine, depends on it's proximity to heat.

How obstructed? If I put the oil cooler over that rad. and leave the filter where it is and just remove the "scoop", the filter will be close to the new oil cooler (heat exchanger). It won't be covered but the two will be face-to-face if you will, within maybe an inch. I have to get the dimensions and mock it up.

Unless your engine compartment is in a vacuum, the air filter can suck air from all sides. If you choose to put an oil cooler in from of it, it will not intake any less air, but it will intake significantly hotter air.
