Let's say the tube has a inside diameter of 1 inch; at 60mph this device would deliver roughly 28 cubic feet per minute of air to the airbox neglecting any funneling effect. It can't hurt really. With engine bay temps as high as they are, the extra air, even at 100 degrees is relatively cool.

It's similar to the Ram-Air pontiacs they used to make, only the air isn't being forced into the filter. Those used suction to pull the air at low speed and then gained a few horses when running. Dyno it with a big *** fan, I'd like to see it.

Suggestions though, use a more funneled shape, collect air from a larger area, and use even larger tubing. Larger Area= more air.

We brainstormed this idea for our Baja Car in SAE.

i believe the size of the tubing is the largest that can be used with an unmodded airbox...

This is a great idea.

I am just wondering why the majority of the tuning companies use this air to cool brakes, not divert it to the intake.

The fan will help, but not enough to see any gains. A fan can't push enough air to compare to when you're driving even 35mph... I've tested this plenty before.

Church's new fan blows 70+ mph! It lifts your leg and pushes fwd if you walk in front of it... I asked him if he noticed a difference in dyno pulls compared to the smaller ones he was using - he didnt in normal circumstances...

I am all in favor of this mod just becuase it is a DIY... and I'm all about that!

But is the debate over airtemps really necessary? Do you think that 5-10F difference at the point of intake is going to equate to 5-10F in the cylinder? There is a TON of hot stuff that the air has to go through, so I see the benifit to this mod being more air, not colder air...

It's not colder air, no matter how much these guys want to convince themselves that it is.

air intake after the MAF sensor is an issue and care should be taken to control it (IMO) - and we all know thatís all about more o2 molecules for better combustion... will this affect that? Possibly, but not horribly (for ppl like me that have done about everything else, little things become a target area).

In THIS case though... its not the air temps after the MAF that you are concerned about - you want the MAF sensor to read cold air... anything before the sensor that is bringing in hot or making intake air hotter is a bad thing because the ECU reads air temps from the MAF sensor and can/will pull timing if the temps are too high - you donít want that for obvious reasons.

Have at it guys and good luck... I'm just giving you another perspective to consider.

^that's only a problem in summer then, since otherwise, air temps near the ground are still much colder than engine bay. also my car is not lowered, so it's not really pulling air from the ground, but maybe a foot and half above ground....

Depends on where you live... earlier this week it was pushing 90 here - and it's not summer.

i guess a dyno is different b/c the car is the mechanism turning the rollers, as opposed to a treadmill, where the machine turns the rollers and not the human
Did you really just say that
