Nice work...I’ve always hear audi does a good job on the maximizing airflow within the stock box, this backs that up. That said, I agree, an intake is a great addition for sound.
Thanks so much for doing this. Really helps many of us make an informed decision, especially on something so expensive (shouldn't be) as an intake upgrade.
FYI the B9/9.5 RS5 (444hp 2.9TT) uses the same factory air filter, so only above that (stage 2), or a bit higher, will there be a benefit to an aftermarket intake on the B9 3.0T.
Just bought the same car same year. I’m glad you put this out there as I’ve been thinking about the JB4. One question, how are you getting such good launches? My S5 doesn’t have a launch option like the RS5. Thanks
helpful tip for stock launches: pump the brakes a good amount beforehand cuz the car feels like it's gonna break loose if not... personal tip that's helped me
But your 0 to 60 and quartermile times clearly show that stock is as good as, if not better than the DIY, doesn't it? Appreciate the good effort to do the tests, but I just thought it showed stock airbox came 2nd. Anyway which JB4 map were you running?
Ive tested the cts on b8 and iats were no different than stock box once accelerating. Itll heat soak at idle but drops immediately once you start air flowing over the front end
@@bhvrdr was this consistent over fresh run or what about after driving the car for a while? I imagine Texas heat would also affect the performance with an open air box.
Great video! i think the air intake would do better pairing it with a turbo inlet. technically you are getting more air but the air restriction is still there. You need better air flow to let that engine breath and to cool.
The b9 uses a zf8 automatic so not the same real launch control of the dsg but putting it in sport tc/esp at least and dynamic give this pseudolaunchcontrol
@@bhvrdr Exactly, but I see a TH-camr destroyed the transmission by doing the same thing as you. At least when you engage launch control the car know your try to launch and actually stop and break boost. I am just saying lol. And you knowledge on the B9 is amazing. Respect!
Wow the speed times are impressive, how can you do the LC at 3,500 rpms? I have an s5 like yours with JB4 and I only can up to 3,000 rpms for the LC Thank you !!!
@@arabe0550 fully deactivated and car in dynamic. I personally put everything in its most aggressive setting (mainly the drivetrain) and do the launch control that way. BMW’s with the same zf8 can get tuned and have high launch control rpms, and after the tune, it seems almost like a dct launch control, instead of feeling like brake torquing.
@@bhvrdr did you do any other mods? Also did you have to send in logs to get the particular map dialed in? That run from your draggy video is impressive. I have an s4 which is a bit lighter and already have intake, dp and intercooler on the way so im curious what my numbers would be!
@@DTM690 not at all. I'm very familiar with logging so just did it myself and iats were fine and knk was being managed well by factory knock control so that's it. Jb4 only mod
So if I were you I would’ve done this test after letting the car cool down. Notice you’re coolant temps and know that all Audi’s come W2A cooled intake air. I would’ve let the car cool down a bit before each run. Just my opinion
This isn’t fair cause after one run the cars are to hot that’s a fact man the fact it never had a a chance to cool they all seem exactly the same but it’s what ever app Varys of shifts and Hill grade both ways
I made sure to address that of course. I datalog all runs starting at the same initial IAT. You achieve this by cruising off boost between runs until enough air has flowed over the front hx to bring iat back down to baseline
You couldn’t have put up a graph, spreadsheet, visual diagram, anything to display the results? Just two minutes of talking, and a shot of the front of the car? I respect that you put together a high-quality, fairly scientific test here, but your sharing of results was really poorly executed. Visual display of results, please!
this is a useless test, the car takes about 15 miles to adjust to new parts. So the sudden changes of parts that you thought was a good thing is what makes this test not usable.
Adaptation of stft and calculated maf is instant. Thats old myths. The vehicle immediately adjust for map otherwise youd run lean or rich. Ltft do take more time but wouldn't confound testing at all.
@@bhvrdrI've got a stage 2 dual pulley 3.0t it definitely does not tune instantly to things like intakes. Even said if all youre getting is a stft adjustment than thats the only benefit you are evaluating. Also the car definitely can run lean or rich at the start of a new install. I've blown out black smoke after a tune before.
@@fastslash25 i stated things like stft, map, calculated maf are indeed intant. Of course not just stft. For intake you are focusing more on map. This is instant. Then your stft adjust for this. You can see this instantly in lambda which was datalogged for every run and is rock steady to target lambda
@@fastslash25 airflow snd iat were of course datalogged but those are variables in making power. You add parts to make power not iat. Iat and aiflow are how you make power. Power is trap speed. But yes i did full datalogging every run. Didnt want to bore with details
Video is four years old and is the most usefull one I’ve seen regarding intakes on Audi B9… nice work
Nice work...I’ve always hear audi does a good job on the maximizing airflow within the stock box, this backs that up. That said, I agree, an intake is a great addition for sound.
And it makes me smile when i pop the hood :)
its all about temps and what a tune might need as supporting mods imo
Great video, all the data with no stupid overlay music or dragging on. Two thumbs up!
Thanks man
Thanks so much for doing this. Really helps many of us make an informed decision, especially on something so expensive (shouldn't be) as an intake upgrade.
Thank you for the research/data. I was under the impression that "JB4" was merely a BMW tune(r).
Thanks yes its amazing how many vehicles they support. I just got one for my alfa giulia too
you are missing the inlet turbo, it also helps the intake
FYI the B9/9.5 RS5 (444hp 2.9TT) uses the same factory air filter, so only above that (stage 2), or a bit higher, will there be a benefit to an aftermarket intake on the B9 3.0T.

Thanks. Its basically brake boost launch control. I brake boost to 3k in sport mode

Will you do an APR tune review?
But your 0 to 60 and quartermile times clearly show that stock is as good as, if not better than the DIY, doesn't it?
Appreciate the good effort to do the tests, but I just thought it showed stock airbox came 2nd.
Anyway which JB4 map were you running?
0-60 measures launch. Et as well. You want to use trap speed if looking at power made. Always trap speed
Thanks!
Most air boxes look like 500-1000 dollars . I found a CTS open intake for $300 but worried about the high intake temps from the engine bay.
Ive tested the cts on b8 and iats were no different than stock box once accelerating. Itll heat soak at idle but drops immediately once you start air flowing over the front end
@@bhvrdr was this consistent over fresh run or what about after driving the car for a while? I imagine Texas heat would also affect the performance with an open air box.

That's like break boosting, should so the Audi "launch control" traction completely off and dynamic.

Bhvrdr, why not just cut out the entire bottom of the stock box so it's similar to the 034?
Yes you could do that and measure again although i suspect the oem 3" intake filter may not be quite as optimal as the 4" 034. Close though
I agree with you 100% I wish you put a cold air intake in it a real one going to be able to drive in the rain then you will see some game
what cold air intake or just intake would you recommend for performance and also are you tuned?
Wow the speed times are impressive, how can you do the LC at 3,500 rpms? I have an s5 like yours with JB4 and I only can up to 3,000 rpms for the LC
Thank you !!!
Just release on the upswing at 3k and itll catch right after
@@bhvrdr didnt work, if i release the brake it makes a lc but at 3,000 rpms :(..
@@bhvrdr did you press the traction button once or hold it to deactivate it full it?
@@arabe0550 fully deactivated and car in dynamic.

BMW’s with the same zf8 can get tuned and have high launch control rpms, and after the tune, it seems almost like a dct launch control, instead of feeling like brake torquing.
But if you put the same setup in an S4 with the supercharged it'll be quicker is instant response will be quicker
Think you will ever do this with an exhaust?
The way i am....probably;)
Is this on jb4 or a tune? Or is just 93 and and the intake?
Thats intakes and jb4 on same setting and fuel
That’s crazy 0-60 time the stock is sub 4 and you’re pushing sub 3, is it just the jb4 and the intake or do you have any other mods?
