I'm glad you Fellas covered this. Definitely didn't know which route when going stage 2. The ratio explanation helped a lot.

[@034motorsport]

Thanks!

[@Weekendwrenching]

Thanks for going over this! Currently awaiting install of my 57.75 and using 034’s stage 2 as I hear should be a world of difference on my q5 3.0T.

[@034motorsport]

Glad to hear! You'll definitely enjoy the upgrade!

[@LuisGomez-ix1pr]

So which pulley would you recommend changing first. I have a c7 z06, upper or lower. I heard the lower pulleys puts stress on the alternator. Not sure to be honest

[@tannerlandry7834]

I have the 207mm and have a major squeak. Brand new part. Would love some customer service. Thank you.

[@tylerspecht7553]

Actually most of the fastest guys are pushing around the 3.4 pulley ratio. Shane horning, Mattys4, and the first 9 second supercharged s5 was on a 3.5 pulley ratio granted with a 50 shot. The only guy in the very low 10s to be on standard pulley ratio is rushil with a good bit of weight reduction and mixing 109 octane with ethanol. My 2 cents are if you live in a hot area go with a normal pulley ratio but if you live somewhere where its mainly colder outside then don't be afraid even going with a 3.4 ratio as the heat is less likely to be an issue

[@calebs281]

im in montana, so cold cold winters and 90 degree summers. we also have 5000ft of elevation. for an extra sporty daily what would you recomend?

[@tylerspecht7553]

@calebs281 high elevation you ideally would want the highest pulley ratio you can get however with the overheating issue on these cars you will still run into that problem. Shooting for something like a 194 crank or a 196 5 crank with a 57mm upper as Long as you upgrade your coolant pump you should be fine

[@dittottid]

Hi there @034Motorsport quick question, For a inner city daily driving where the environment mostly gets us in a situation where short-distance acceleration is more useful than long-distance top speed, and wanting to optimise the performance boost without losing efficiency and reliability, would you suggest more the 179 mil with the stock upper pulley or the 179 mil with the upgraded upper pulley? Thank you! I am new to this and trying to understand better. Additional note: I live in a hot and humid region so heat is an important factor

[@034motorsport]

Hey there! The 179mm Crank Pulley Setup with the stock or upgraded upper is a great setup as it produces less heat compared to the 190mm setup. The preference for going single or dual pulley is entirely up to you, just be sure you're fulfilling the required hardware for each by referencing our product page here: www.034motorsport.com/b8-b8-5-audi-s4-s5-3-0-tfsi-performance-software-stage-1-2-plus-dual-pulley-6877.html

Would this work on crec engine

[@doronkoz]

Hi... great videos you have. Tell me please.... I have SQ5 2015 and I ordered now 034 crank 207mm pulley. (Like dual pulley) And a heat exchanger "mercracing" And I took out the inside of the cat material = free flow. My question is... what software you recommend me to run for this??? 034 or IE or APR or what??? I don't want to go E40 or so.. Only 91fuel with it. Of course what is your 034 price???... and how can I order it?

[@TheBigZUnit]

You think these guys are going to recommend IE or APR or GIAC if they’re also a tuning company and they want to sell their software?

[@davidsibble7429]

Question…is the 034 crank pulley as balanced as the stock pulley is? (especially long term applications) and reliability is concerned?

[@034motorsport]

We do not specifically balance, the pulleys, but since the aluminum material we use is inherently, a very uniform material, and the part is perfectly symmetrical then it is inherently a very balanced piece already, and no further balancing is needed.

[@bmorenerde]

would the 3.29 ratio be too aggressive for a daily driver? is it only the upgraded sc pulley that increases heat, or is it the higher ratio in general that aids in heat production

[@034motorsport]

A 3.29 ratio would not be too aggressive for a daily driver. It is the higher pulley ratio in general that increases heat production, which is why we list an upgraded heat exchanger as a requirement once you go Stage 2+.

[@avgfinnishdude]

Would you recommend a7 with zf8 or s5 with dsg? and how different the engines are although they are pretty much the same

[@034motorsport]

Both are very different cars and are great in their own ways!

[@m3division235]

Can I run the 207 as a single on just stage the stage file 2 or do I have to be on the stage 2 + file and can I run the e40 blend with the 207 crank?

[@034motorsport]

You will need to run the Stage 2+ file. Stage 2+ has the following available octanes: 91, 93, 100, 104, E40.

The TCU software upgrade is a required upgrade in order to utilize our Stage 2 & 2+ software safely

[@joserivera7694]

Perfect thank you so much for clarifying that for me, now im actually excited to order my parts, and I should get the heat exchanger as well?

[@xryzerr]

would your guys’ 57 sc pulley be compatible with ecs 187 cp and their kevlar reinforced belt?

[@034motorsport]

Yes it would be

[@jessecooper537]

What would your recommendation be for a safe and solid approach on pulley setup for a casual driving experience?

[@034motorsport]

For dual pulley, we recommend the 179/57 setup as it minimizes heat! The most common setup is 190/57 or 207/stock

[@stacks_producer]

For someone who mostly uses their B8 as a daily driver, but has the occasional blast with the local RS/M car on the way to work, would you recommend stock upper and 034 lower? And if so which size would you recommend for this type of car use?

[@034motorsport]

Any pulley ratio is suitable so long as you have the proper cooling setup! For someone not looking to go all-out, we'd recommend sticking to the 179mm lower.

[@stacks_producer]

[@joaquinmendez7488]

could I go stage 2 without any pulley modifications or do I need to chose stage 1. my understanding was stage 2+ was the only setup that needed a pulley

Stage 2 is a Single Pulley upgrade and Stage 2+ is a Dual Pulley upgrade. Stage 1 can be installed on a bone stock car.

[@thatdudemar3364]

I’m switching over to 034 from EPL dual pulley my crank pulley is a 192mm with the smaller upper pulley do you have a tune for that? Is there that much of a difference from a 190mm to 192mm?

[@034motorsport]

We support all pulley configurations so long as they fall under normal dual pulley ratios. You’re good to go on our software. We offer a Switchover Discount for owners looking to make the switch to our calibration software. Shoot our team and email at [e-mail] and we’ll get you set up there!

[@shuckarelli]

Ok so I have a question, I have a 2011 A6 supercharger and what I have done is remove part of the material we're the throttle body goes and welded on a 4bbl carburetor flange! I plan on adapting this to go on a 1960 cris craft poly 318 manifold and running this in my 65 dodge D100! How fast can I spin this supercharger and what kind of boost am I looking at?

[@Andrew-ys2nl]

For stage 2 single pulley is there any risk with the 190mm crank pulley I’ve heard if going stage 2 single pulley to do the supercharger pulley and not the crank pulley because doing crank pulley could cause engine to blow

[@034motorsport]

As long as your supercharger pulley remains stock, you’ll be good to go on our Stage 2 setup with a 190mm crank

[@ProjectArjun]

If I remove my smaller supercharger pulley and use the stock size and upgrade the crank pulley to 179mm is this setup going to generate lesser heat versus 57.75mm SC pulley + stock crank pulley setup?

[@034motorsport]

You'd be splitting hairs. The differences on single pulley with those setups is going to be relatively small. That said, it would be beneficial to remove the factory crank pulley as it is a prone failure point. It would also be beneficial to upgrade your factory heat exchanger!

[@scott8934]

Hello gents! Seeing no compatibility listed for the 4M Q7. Is that correct? What’s the difference in application there? Thanks!

[@034motorsport]

That is correct. The 4M Q7 3.0T has a CREC engine, which has a different supercharger and utilizes a bolt-on pulley and a magnetic clutch design. We currently do not offer a supercharger pully upgrade for the CREC motor, but we are working on alternative solutions, as well as tuning software!

[@gurmantamber7768]

Can run the 207mm pulley with stage 2 software? Waiting on stage 2+ but in the meantime hoping I can drive on stage 2 and DP Ratio (207mm)

[@034motorsport]

You can run our Stage 2 tune with a DP ratio (207mm) in the meantime while you are waiting for Stage 2+ without an issue. Though, we recommend getting on that Stage 2+ tune asap!

For stage one you need the factory cat converters need to be in place, no other modifications are required.

[@ahren5043]

Is it possible to use the 034 upper/OEM lower without upgrading cooling system? I know it would be best to upgrade cooling too, but is it possible without upgrading it and not overheat?

[@034motorsport]

You can, though you'll certainly run into heatsoak issues. We always recommend an upgraded HX with an upgraded pulley.

[@ccssid1232]

I ran stock lower, 57.75 upper, stock heat exchanger for approximately 30,000 miles . Never any issues. B8 S4. Note...never tracked the car.

[@ProjectArjun]

At what point do you recommend upgrading the cooling system? Does a 3.1 ratio require a cooling system upgrade?

[@034motorsport]

With any pulley upgrade we would recommend a cooling system upgrade. Our heat exchangers are a great option that perform exceptionally well! There are benefits to having an upgraded HX on factory pulleys as well

[@ProjectArjun]

@@034motorsport Thanks, is there a certain ratio point or cut off at which you absolutely advise or in other words require the end user to upgrade their cooling system to prevent any potential damage to the engine?

[@lucaskuntz8216]

@@ProjectArjun Generally speaking, getting close to that 3.0 ratio mark will require a heat exchanger. Depends largely on how hard you’re going to drive the car, and the climate it’s in. I have an upgraded 57mm supercharger pulley on my A6 and haven’t seen any issues or heat soak from just that alone, all stock cooling. However, I don’t push the car super hard, and it tends to be a bit cooler here in Canada

[@racing4recovery593]

@@ProjectArjun I'd look at C7 Owners Page. He has a great breakdown on why the heat exchanger should be your first mod. When the intake air temps get to hot, the car starts to take timing and power out! Up to 40% he claimed. Just a thought to consider.

[@tylerevans2261]

I have the dual pulley kit. 190mm lower and and the 57.70mm SC pulley. Can I run both on a stage one tune and not upgrade cooling and exhaust? What would be the best combination? Just doing some spirited driving currently and just want an upgrade that is reliable and not a lot of stress on the engine. Can always adjust accordingly if I decide to track in the future.

[@034motorsport]

Having both pullies upgraded would require our Stage 2+ software. Stage 1 is designed for factory upper and lower pullies, and we cannot recommend running Stage 1 in your case! You would need an intake and upgraded heat exchanger at a minimum to run with your dual pullies and Stage 2+ tune.

[@mattleifer4884]

Would it be cooler on the supercharger to do a 179 crank vs the 57 supercharger pulley?

[@034motorsport]

They're both pretty much the same ratio. 179/63.25 = 2.83 162.25/57.7 = 2.81 We'd do the crank pulley as the factory one is prone to failure

57/190 is a common setup! You'll definitely need a quality heat exchanger to manage the heat generated, such as our own heat exchanger kit!

[@doronkoz]

In this 57x190 or just 207xstock what is the risk for the engine or supercharger? Or other parts? And from other side...what is the improvement in the power? In HP.. but in 91octan... not higher. There is a huge difference from stage 1 to stage 2plus?

I went from factory pulley ratio/intake stage 1 to 187.3x57.3 stage 2+. 93 octane. I did also did hx same time I upgraded the pulleys. I must say I am running similar 60-130 times to when I was just stage 1 with intake and no hx. Any reason for this? I don’t have test pipes yet but still upgraded the ratio. It seems to be inconsistent too as I just did 12.07 60-130 and then a 10.29 60-130 about 15 minutes later (didn’t let the car cool off or anything). Any reasoning?

[@Minecraft007crave]

Is it possible at all to run the 207mm with a smaller SC pulley?

[@Minecraft007crave]

Or what would be the most aggressive dual pulley setup?

[@034motorsport]

We cannot recommend running the 207mm Crank Pulley with an upgraded SC pulley. It is only designed to be used with the OEM SC pulley. Running a 207 with an upgraded SC pulley would spin the supercharger faster producing more boost, but you would also be producing a lot more heat which would hurt performance. Some of our fastest customers are actually running our 179mm + SC pulley.
