B 8.5 2.0 TFSI. Where to start? How fast can I GO!!

[Striker27]

Well as the title says. Have a 2016 2.0 TFSI. Where should I start on going faster. A tune? An Intake? Exhaust? Bigger turbo? How much does all this really change the speed of the car? I never hear how much faster this car is when you make changes. Does any one have some real world input. Would be great to hear.

[schwiz23]

A different car.

A different car.

To go faster: modify the driver.

[eljay]

To give you a start though, a software tune will unlock some immediate power. After that, it's a slippery slope and only your wallet can stop you.

Beat me to.it.. lol.

Go buy a ricer car if you want to race around your streets. This is a big heavy car for a 2.0T this car will do over 100mph pretty quick.
Do you really want faster ? Or just quicker.
If you want quicker start dumping weight

Geez that was harsh. I just wanted something a bit quicker to have some fun with as far as my wife’s winter car goes. I already have a ricer. I have talked to a Unitronic dealer in town and will get a tune in the next few weeks. We are under a Lockdown at the moment so it is hard to speak with them about much. I have installed an AFM filter will probably do an exhaust next. Would like to have a car that runs 13’s or so. Is that possible with a tune and exhaust. Probably I will stay Stage 1. Simply because my wife would never really put 93 in the car the whole Premium thing is a bit confusing to her now that we don’t have a pump jockey at the station and she has to fill her own car. They also don’t have 93 at Costco.

The only way you will get into the 12's is with a bigger turbo. If you want to dump thousands into the car, that's the way to go. Don't waste time and money into mods like exhaust systems or stage 1-2 tunes. You go bigger turbo, intercooler, and HFC.

[fastboatster]

how about boss 500 turbo kit from cts:

See I get the whole idea of the upgrades. But what do you get in actual numbers. How much faster is it?? The aftermarket always seem to talk up the product. But no one ever seems to quantify the whole thing.

The comments above speak the truth!lol. I started out stage 1+. It was fun until it wasn’t and I wanted to be “faster and quicker”. At the end of the day, you’ll end up with a “Fast 2.0t A4” - not necessarily a “fast car”. If you throw money at the car, it MIGHT get faster.

Honestly though, I love this car. I’ve done a mix of performance and oem+ cosmetic mods. It’s not a flip - I intend to keep it and enjoy it. When the engine blows - I will rebuild it in my backyard. I do all the work myself. If I had to go to a shop - I would not have started modding. This is my first “project” car (also a daily driver) so it is very special to me.

You asked for real world performance - here’s where I am at with crappy tires and suspension (next on my list). I think my car is on the slower end of the fast A4’s. Lol. I’m currently K04 with supporting mods.

My A4 (in its current state) definitely holds it’s own in town and on the highway and is a blast to drive.

Do your research, browse the threads. Most of the questions you have are probably already answered. This is an old platform and most mods have been tried and tested. No need to be a guinea pig at this point (unless you want to). There’s a wealth of knowledge on these threads that will get you where you want to be. Just have your wallet ready!

My first piece of advice would be committing to premium gas!

I think a simple way to get 300hp+ is to go KO4 with a tune, and a hi flo cat. Intercooler modifications seem to be popular around here but I haven't dropped the money on that just yet, so i can't speak to it, I just know that my car hauls ass compared to stock.

There is a guy on youtube that added a new intake with meth injection and he claims 400hp with k04.

All of this can be done with just bolt ons.

For more serious power, I suppose you can beef up your internals and put on a massive turbo, upgraded fuel system and custom tune. Just depends how much you wanna pay.

[Striker27]

Thanks for the answers and advice. I think I will try to keep the stock turbo for this year. It won’t be all that fast but might be fun. Will
Do the exhaust HFC intercooler mods and of course a tune. What happens when you change the turbo do You run into issues?? I know premium is a big thing. But around where I am 93 is about all I can get at a few stations. Most are 91.

I run premium (93) which is easy to find everywhere.

My IE K04 tune maintained the same gas mileage as before. I get about 370 miles to a tank daily driving, and around 400 on highway trips to detroit.

Drivability is same as stock. It's a pretty impressive tune.

are you talking about fast as in overall top speed, or quick as in how quickly you'll get up to speed. I had k04 & custom tune with test pipe, intake, FMIC, and exhaust and it tops out at ~135mph. super fun to drive, but still leaves you wanting a lot more.

[HOJeepster]

Get a stage 1 and run e85 to start. If that's not enough, go K04 with HFC and Intercooler. That's what I'll be doing after owning a B8.5 for 4 months. Should be plenty fun.

You are asking for a single answer to a question with multiple permutations of inputs. There just isn't a single answer. That is why even the big turbo vendors don't quote any numbers because "it depends". Makers/vendors of individual components quote numbers for those components if they have dyno'd them and can isolate the change to just that component. For example, if you take a stock A4 and add Stage 1, you get X hp, everything else being equal! Now, is everything else always equal?
What if I add intake (what type/make), exhaust (what type/make), cat (what type/make), intercooler (what type/make), injectors, spark plugs etc. etc.?

Then there's the question of going fast.
- In a straight line? Quarter mile? On what tires? What outside temperature? What elevation? What's the vehicle weight?
- Around turns? What suspension? What brakes?

Depending on the above, the answer can be 30-200 hp as some of the others are indicating.

Do you see my point?

Premium is a thing even if the car is stock. It says it on your gas door you are supposed to run premium fuel only.

[Striker27]

Premium is 91 where I am Located.

[Striker27]

E85 is not available where I am located

[Striker27]

@ present. We have 87 regular. 89 mid grade and 91 premium available. No E85. May be one or two stations have 93

Most brands have 91 octane tunes, but word of warning, even with mods, 91 tunes, including the K04 if you do get one, are severely under powered because of that fact.

Don't you have any Petro Canada stations near you with 94? I travel around all over Ontario, and yes while there are some stations that only have 91, those are rare and more in rural areas. And yes, unfortunately e85 in Canada seems to be like a unicorn ...

[Striker27]

Nearest Petro is around 40 Minutes from me. I am kinda rural....

A4’s are not fast and will most likely never be fast in our generation

I hope to prove that statement wrong. But still a long ways to go. And yes. Not fast for cheap. That is absolutely confirmed. But if the few of us that are trying to push this platform waaaay forward, succeed and a market develops then the costs to do what we are doing will become more affordable.

Fingers crossed.

I think we are too limited in our demographic to sway any big market changes

I hope you are able to succeed but it’s like you say at what cost. I always like to compare the hp/$ of cars and modifications

I just don’t think there is enough of us to get a real motor build program or head build and all the tuners aren’t thinking about b8’s anymore

The odds are stacked against the b8 a4
