Q5 cold air intake upgrade!

Q5 Tdi upgrade air intake or not?
Hi everyone,
I ‘ve had my oem turbo rebuilted: billet, bearings, ..., egr, swirl flap and Add blue delete. New down pipe, cat less. Stage 4 tuning with 4 bar map sensor.
Right now, my turbo is pushing 35 psi.I might have around 300whp, will confirm in the spring with a dyno!
I really need more air for the turbo, suggestion from Tuner!
I want to built my own cold air intake, because it kills me to pay 1000$ for apr cold air intake!
And the opening beside the turbo is so small! I was thinking to fit the SQ5 TDI, it’s much larger then mine, but not sure it will fit!
Do you have any suggestions?
Thanks!

They come factory with a great intake....

Assuming you have the 2.0 and SQ5 is 3.0? The stock elbow is fairly tiny at the end that meets the turbo at least on my 2.0. Stock is 41mm (I'm sure it's different but maybe similar) on the elbow inside diameter. What I have now matches the inlet on the 2260 turbo while retaining stock airbox. Has to help at least a little bit I'd imagine. My measurements tell me I gained 10mm just by eliminating that elbow...again, retaining the stock airbox.

How about an intercooler upgrade, would help a lot as well I'd imagine.

Pretty sure all the Q5's got the 3L V6. I think the only Audi that got the 2L (over here anyhow)was the A3.

I guess I could have deduced that from the 35psi mention..whoops. Still think there is merritt to increasing intake size to at least match the compressor inlet though.

"Still think there is merritt" to increasing intake size to at least match the compressor inlet though." Adjat

I'll go along with that, I've got a PD150 airbox with bigger MAF going on
my ALH soon, cleaning up the plumbing to the turbo, and larger diameter,
has got to help IMO.

Yes I have a Q5 3.0L V6 TDI.
I will mesure the inside of the turbo and of the inlet of the turbo!
I thought the intercooler on the Q5 is large enough!

I run the Q5 with gtb2565 and stock intake, 2.4 bar boost 360+ hp , stock intake is perfect.
Big frontal IC surely helps keeping IAT down.

My friend with similar setup runs 400+hp and no need for expensive air intake. He's got probably the fastest Q5 there is 100-200 under 12seconds

Doing so is NOT and upgrade. It's a downgrade. Hp and engine and turbo killer. Please look at the cold air intakes sticky.

Dont want to match the intake port on the turbo air speed velocity vs CFM. The turbo is doing a fine job as is.

Hi Macradiators,
Can you tell me what brand and size of IC that is on your Q5?

Its something made locally, 700x 300 x70mm tube&fin technology. Awesome and under 150euro here from factory.

No they dont, a large spectre cone filter swallows air compared to that.

Another clueless post about air filters on turbo cars. Do you have any idea what you just said and why ots a bad idea.
You might be correct that put to the test against a flow bench that the OEM filter vs an aftermarket bug screen scam part wont flow as much, you are doing just that, sucking up debris and "adding air" to a system that can add it's own air via a turbo.
Please think before you post. Also spectre filters are very piss poor quality. I've had to use a few and I've never been impressed. The chinisium they come with always fails but customer service was always happy to send me replacements.
