Really? I got to see it for myself. Lol

While the power increase numbers are good they might be actually better when you're driving as you're really getting a better ram affect as air flow is across the entire front end especially where the airbox has it's front feed. Only way to tell is to measure ambient air temp versus air temp in the box, obviously the smaller the delta between the two the more efficient you will run to maximize power. Thanks for sharing your test data.

I figured out this intake will work with a whipple, but still unsure if it seals with a pre-2014 hood. Also, does anyone think the windshield washer bottle is in the way?

You're probably right, I was thinking the same thing. The only way to find out is like you said to measure ait to at in the air box. No problem.

I looked at the whole washer bottle issue when I had my stock air intake out and I just don't see how it is that big of a deterrent. Air is hitting the car in the front, the 1LE splitter covers most of the bottom to the wheel well. Maybe on non splitter cars the air is more accessable from the bottom, but the air would have to travel backwards and up to get any effect. If you look at the FEA flow data of the Z28 and how the air flows thru the grill and out the hood, but it flows towards the headlights. I think if you mod the plastic part behind the grill directing air at the radiator that this would increase the ram effect. The quickest path is around the back of the headlight to the grill. In mustangs the Drag trick was to pull the headlight at the track.

When I take the bumper cover off this weekend to do the grille, I am going to see if I can design a ram-air scoop or redirect from the grill to the air intake.


Note the air behind the Z28 badge, if the plastic directing was opened up a little I could see it increase. The above pic showing the air movement out of the hood, is the reason I removed the rain deflector. Lower hood pressure means faster times.



Look at the air hitting the headlight area and towards the center, there is alot of resistance that could flow to the filter

This is true for the gen 5 refresh but what about pre-2014? Its been proven it blocks some air on intakes.

or you can get one of these:

I believe cooler air is pulled from the lower grill. The OEM washer bottle is moved to give room for the scoop.

Those are nice for rotofab, CAI, etc before FI. After FI, they don't matter. I'm trying to see if bottle effects the z/28 at all, but based on a pictures it appears it does not.

On pre-2014? Yes I believe so. That's my concern with how the z/28 intake is shaped on a pre-2014.

Ok, gotcha. Sorry, I didn't mean to add confusion to the discussion, my response was more for Chris1SS1LE as information if he was not aware of the scoop that is available for cai's.

[GoldCartridgeGamer]

My apologies. I wasn't sure who your replies were directed towards. I was just trying to add to the conversation and make sure I was clear myself.

I've been contemplating the same idea, I was thinking of either modifying the plastic baffle behind the badge or removing it. I will like to know what you find out. Keep us posted!

Are those the Z28 brake ducts?

I believe the washer bottle relocation will only benefit some Cold Air Intakes, but not the Z28 intake. Seems to me that the Z28 intake can be installed in a pre-14 model without any issues. In order to induce more air flow to the Z28 intake, the plastice baffle behind the SS or Z28 badge would have to be modified or removed!
