For the intake temps, they were taken during a 3-mile drive with cruise control set at 55. I snapped a picture at the lowest temps.

 

how fast were you going. a similar test showed that results were the same at higher speeds since the bumper is designed to push air over the car.

 

 

Raining today, i guess i could do it. But im thinking a dry day would be better "normal" conditions. Adam from z1 said he did this a few years ago and said air gets up there own its own well enough. Ducts dont do anything, but its fun to experiment anyway.

 

if you plugged the actual inlet duct on the bumper, and not the cold-air duct entrance on the V2 intake then your test is misleading.

the stock car has a hole there that feeds air in from the bumper, just not a diverter.

you need to retest with the correct hole plugged.

 

Nice work Spork!

 

I wondered if the duct was worth putting on. Since I have to take the bumper off to paint the mesh on my V2 black, I'll be putting the duct in as well. Thanks Spork!

 

you should run the duct if only because otherwise the bumper has the funky little slice cut out of it.

 

I plugged the V2 intake duct. Look at the picture of the towels.

 

yeah, it looked like the inlet on the radiator support.

on second look: you are right. lol.

can you easily remove the duct? I would be interested to see what flow would be like with the increased volume of empty space behind the bumper.

I would also like to see what the difference is between the stock bumper and V2 (minus duct)... that would also be very interesting.

again, sorry for my mistake.

 

No prob man. The intake duct is relatively easy to take off, but it requires me taking my bumper off again... :/

 

oh man, that would be sweet. you rule.

 

Does anyone make something like this for the stock bumper? I don't want to cut up my front bumper and get the bumper one.

 

Nice experiment.

But you still might have a small experimental error with plugging up the v2 airduct hole. It would be more accurate if you remove the air duct vs. plugging it since naturally your OEM bumper don't come with blocked up v2 air ducts by the intake area
