What is this hanging off the turbo?



thanks,

Looks to be a air filter pipe assembly

 

Someone's attempt at over complicating an intake. Looks liek a job well done.

 

lol, i wouldnt have thought of that remark but i think what u said may be true. welds look good though.

they do that to give it more volume, similar to a plenum.

I've seen that on more than one bmw install.

 

This looks to be on a audi 1.8t. I can't see why they need volume on a intake pre-turbo. and it's definitely not a space issue, so .....

 

Finda a good sized filter that will fit in there with the head light installed, then you'll know why I made it. Yes the idea is to have a plennum for the turbo.

Well i stand corrected on the space issue, my bad. Care to elaborate on the 'plenum" idea. Never heard of that before.

 

From what I gather, the idea is that the turbo is now able to pull directly from a large volume of air much like it would if it was open air. This is unlike an intake pipe because it has to pull the air through the tube first which creates drag and heat.

I'm no expert, just what I've gathered.

 

There is a tube with a common filter off to the right of it shooting downward.

Bet's a regular tube will make better minimal gain.

 

I agree, I don't think it will really do all that much realistically for performance. But, it is a pretty efficient way to do a direct 90 off the turbo, even if it is ugly (not the fab, the fab looks great. It's just ugly, lol)

 

Compressor has to fill up that space first?

A normal 90 bend physically governs the direction of air, want the same effect? Get a bigger tube ?

I think I'll take the normal 90 degree bend some of those German car builders really do some odd things.

 

I don't know how much space is actually there, most 90* bends that are over 3" have a 4" radius, which in tight spaces is actually really big.

Also, being as it does have a normal sized inlet, wouldn't the large volume actually create a vacuum effect with the compressor actually forcefully pulling air in. In other words, you'd never have an empty plenum, it would "fill itself" as the compressor pulled air out of the plenum, the plenum would pull more air in?

 

If that was the case that person could've made a box there with a supply tube with feeding the box with a forward facing velocity stack, not sure if he was trying to be different, but this example I explain is what many premium race cars use since it effect their dynamic throttle response vs the road course ; corners/straights .

 

Gotcha, and I agree I would also prefer a forward facing velocity stack myself. Thanks for the info by the way.

 

me = winning... again

 

While thinking how to improve the intake on a customers car I came up with the exact same idea in my head. Althought it would have had a forward facing velocity stack/ram air.

This "should" work better than a 90 degree bend off the turbo, especially if the radius is tight. Although there is more to it. I.e. if the 90 bend gets a good vortex, and this has airflow from 1 side that effects this it could change things somewhat.
