Modded Audi A5 2.0T - What else can I do to increase torque?

[LordJordi95]

Hi everyone,

I recently modded my Audi B8 A5 2.0T and took it from stock to K04 with all the recommend supporting mods.

Here is a list of the mods on my car:

• Performance By IE K04 Tune
• Performance By IE Front Mount Intercooler
• Performance By IE Cold Air Intake
• Performance By IE Downpipe
• AWE Quad Touring Exhaust
• Borg Warner K04 Turbocharger

After installing everything on my car I’m still not satisfied with the torque my car has. I have driven a new stock A3 with a 2.0T and honestly feel the A3 push me back into my seat a lot harder than my modded A5. My A5 is very quick, I recently did a 0-60 test in about 4.7 seconds (not sure how accurate the Drag Racer app is tho) and I have had a shop look over my car to ensure nothing was causing loss of power.

The shop looked over the entire car and found no boost leaks or exhaust leaks, and my car is apparently up to date on all the maintenance items (I am running the R8 coil packs with NGK spark plugs btw).

**Anyone have any guidance or tips or knowledge on how to increase torque after performing the mods I have on my car?**

The only thing I have found online which may help is to upgrade my Intake Manifold to the Performance By IE Manifold which I plan to do in a few weeks.

I’m open to any suggestions you may have and hopefully someone can help me find a way to increase the torque on my A5! Just wanted to mention real quick that my tune does not support E85 and it’s hard to find in my area.

Also I’m more than happy to answer any questions anyone may have on the current mods I have on my car.

Thanks in advance!

Hop over to the A4 B8 forum. There is an ongoing thread on ko4 performance. It's currently 63 pages long and filled with a ton of information.

Damn I hate replies like this when people ask specific questions... dont you ever not troll? Your thread does NOTHING but clutter the forums. When someone needs help 2 years from now and searches the forums they find your useless replies. I just looked at your profile and latest posts and you do stuff like this often, "search the forum" or make people feel stupid about their questions..

Now with that said, you dont even have to reply to this post because it'll clutter it up even more. So if you do reply I wont be. If you want to reply just PM me about it.

[JLAllroad]

As long as everything is working as designed, based on your mod list, the only way to add power down low is to add timing.

Btw I do not think that the IE intake will get you what you want, if anything, on your current turbo.

Reach out to IE, tell them your concerns, they will have you run logs and see if there is anything on their end that they can tweak. You should also post the logs here, this will let us know how you are running.

IE does not currently have E85 support but does have a 100 oct file. VS 93 it’s +7lbft@3000rpm and +29lbft@3500 and +26lbft@peak.

There are many that will run a higher octane file by running meth injection but this has a list of compromises that would need to be considered. I’ll let someone else speak to those.

It answers his question about more TQ. Not a troll or whiner, he asked a question I answered. He's comparing an A3 being peppy to a pig of an A5. A 2.0t in both cars would be a huge difference especially considering weight. A 2.0t and your asking for more torque, best answer I can think of is trade it in for an S5 which is a v6 or v8. Just because you dont like the response doesnt mean it's not helpful. Dont be an edgelord. 2 years from now, lol the forum is already cluttered beyond repair why do you think he asked the question to begin with? Guaranteed he couldn't find crap on it.

Yeah to be honest I’ve been thinking about trading it in for Audi S6. The only thing holding me back is the fact I just dropped all the money for these mods and it would’ve all been for nothing. Lesson learned though on my part, I should’ve had a better understand of how much torque I would have.

Yeah I’ve reached out to Performance By IE. My POWERLink USB to OBD adapter stopped working so we are troubleshooting that right now, once we get it working I will post my logs on here.

I’m going to do some research on Meth Injection. This A5 is my daily driver and my only car so hopefully I can find a kit that isn’t too high maintenance.

You wouldn't regret it!!! S4, S5, or S6. Tons of torque. 2.0t only thing that I can come up with besides getting bigger engine is major engine work. I hear ya with you have to pay to play, enjoy it for a while and save some coin than find something. I still cant believe how underpowered these lil 2.0t's are. Scion TC w/2.4 makes 160hp and 2.5 makes 179hp all motor and with a turbo the 2.0t it's barely 210hp. My A3 is peppy but not at all fast, with a downtube, full exhaust, fmic, tune, K04 swap it's still nothing like I wanted, I stepped up to the S4 and what a difference just stock even, now its stage 1 and is perfect for a daily. It's no 2.0t on gas but wow superior for sure in performance. Plus Wards 10 best engine for years the 3.0t is amazingingly engineered and extremely reliable. PM me if you'd like some more info on my A3.

Yeah I’ve heard a lot of good things about the 3.0T. Simple pulley upgrade with a tune and they’re making crazy HP. I’m going to stay hopeful and give my car a few more months and see if there is a way to get an another 50 - 100 lb ft of torque to the wheels.

If it’s not possible I’m going to do as you suggested and trade her in for something new!

[shortyolsen2017]

Looks like with IE and the K04 upgrade you should be around 343hp and 363 btq equals to about stage 2-3ish which is
151hp and 137tq from stock.

That thing should rip pretty good for a 3600lb beast, about equal to a stockish S4 or S5 in performance anyway. 333hp/325tq.

You may need to buy a different car...

I have done all mods as you have, with the exception of using APR as my hardware and tune supplier. If your car doesn't just rip when it is in sport mod, there's a problem or your expectations are much too high. You've done just about all you can. But you have to drive it in sport or manual.

[pdan]

I was having similar thoughts OP. I bought my A5 as a daily while my GTI is in storage. Plan was to keep it stock and DD it while saving money for either an S5 or contributing towards another larger car build project. But after recent events the amount of time it would take to save to by the S5 in cash and be financially comfortable went way up.

I love the car but it was way to slow and boring stock. So I just spend a decent amount of cash on it going to stage 2 and some other nice stuff. It should tide me over I think now until I can get into something better. I’ve always heard by the most amount of car you can start with and go from there. Better usually to start with a solid base if you plan on modding and modding and modding.

As far as above k04 performance it seems most of the stuff has been talked about, water meth or having IE look at the logs. Other than that you’re getting deep into engine build territory I think.

Yeah, I thought it would rip pretty good too which is why I went this route. I didn’t expect to be so disappointed with 343hp and 363 btq. Now that I think about it, I used to drive my older brothers Mercedes CLK 500 with the V8 for a bit. I know it’s not apples to apples comparison but that car was rated at 302 HP and 339 ft lbs of torque. It felt twice as fast. Never felt a car throw me back into my seat as hard as that car. Years after driving it I still remember it and to be honest I was chasing that feeling with my A5 a little. They’re around the same size and the A5 is lighter and after reading what IE claims to get out of the 2.0T I thought I would have something similar. I was way off.

Yeah, I always drive it in Sport or Manual. My tune supplier is IE but I was lucky to get the APR Borg Warner Turbo kit (Borg Warner Turbo’s are out of stock and back ordered for 6 months to a year).

What tune supplier do you use on your A5?

Hmm, any plans on going K04? And yes I’m going to definitely have IE look at my logs and I’m going most likely avoid any engine builds lol. Rather get a new car at that point.

Probably eventually yeah. Right now I don’t really want to drop another $2-3000 or so on the car though. Still have to put in a clutch ha.

I’m going to mention something else.

A K04 car can be deceptively quick given the smooth delivery of power. Some would compare it to a large 6cyl that can keep up with V8’s, easily a sub 13 second car.

This power delivery is actually good for engine longevity. Increasing torque (down low) too much above your current (assumed) levels and you would want to consider a built bottom end.

Hmm so you’re saying rebuild the bottom of the engine and then possibly upgrade for a larger turbo to create more power? I will look up and see if they’re any kits and tunes available.

I’m saying that if you ask too much of this motor below 3000rpm you run the risk of eventually kicking a rod through the side of the block.

There are only a handful of people (on AZ) that have successfully gone bigger than K04 and most have still not seen the full benefit as there are a number of hurdles, tuning (beyond 24psi), valve train springs (above 6800), and fueling with and without E85.

I have APR... I've done about all that can be done to extract power from my 2.0T, Intake, downpipe/HFC, Exhaust,K04, cooling, and tune. I really comes alive in sport mode. To really notice the gains, I'd like to drive a stock 2.0T as a personal assessment of improvement.

I completely agree, a K04 car is quick, it's not snap your head back torque, but it's there... it's smooth and linear. It will definitely run with a NA V8 and I know it will outrun the A5 3.2, just doesn't sound as good ;-)

[19birel]

I have heard that IE's tune's don't have quite the same punch as APR off the line, perhaps it's just the power delivery that has it feeling not quite as fast.

Yeah, I'm thinking the same thing right now. My IE POWERLink adapter broke so I ordered a new one which will be here on Monday. I'm going to send my Datalogs to IE and post it on this thread as well.

Anyone on here switch from a IE K04 to a different tune? If so anyone notice any increases in low end power?

I'm a fool for not doing my research before doing these mods. All I wanted was low end power lol

[A6sport]

Well, you've done it now... you just need to learn how to drive it and keep it in its power band, there's plenty of power there from that little 2.0T!

As you guys requested, I pulled a data log from my car.

4th gear WOT from 2000 to 6000 RPM.

https://datazap.me/u/lordjordi95/682...?log=0&data=11

[JLAllroad]

I would suggest adding some pre-load (crack pressure) to your wastegate. This will help hit the boost targets, gain some response down low and cut a bit of the duty cycle up high.

First you need to measure, with regulated air, what your current pre-load is (when the WG rod first starts movin).

Okay thanks for that! I will pass that on to Performance By IE so hopefully they can assist me with this. Performance by IE has been helpful so far, they found a good amount of ignition retard throughout the log and asked me to flash the 91 Octane Tune (I only put 93 Octane in my car and I was running the 93 Octane tune previously).

I will create a new data log with the 91 tune, I installed it and drove around for a bit on it and so far notice there is a good bit more power.

Here is the log from driving around: https://datazap.me/u/lordjordi95/682...a=8-9-10-11-19 but again I will create a new one from 4th gear 2000 RPM to Redline tonight or tomorrow.

Thanks again everyone!

Hello

Can someone help understand why card is lacking HP and Torque on with APR stage 2 CTS downpipe with CAT

I attached file with boost reading

Last year was see more torque and HP 300

This year only see around 220 Torque and Hp

I need help to understand what could be causing this
