034Motorsport 3.0 TFSI 179mm Crank Pulley Upgrade for B8/B8.5 Audi S4/S5/Q5/SQ5 & C7 A6/A7

If you re looking to squeeze a bit more life out of your B8/B8.5 Audi S4, S5, Q5, SQ5, or even the C7 A6/A7, the 034Motorsport 3.0 TFSI Supercharger 179mm Crank Pulley Upgrade is a solid choice. This isn t just some flashy add-on; it genuinely boosts your supercharger's rotational speed, which translates to more boost for your engine. Trust me, you ll feel the difference.

What I love about this upgrade is that it s designed to work seamlessly with both the stock supercharger pulley and the 034Motorsport supercharger pulley upgrade. You re not locked into one option, which is great if you re planning to evolve your setup over time.

Let s talk about the build. This pulley is machined from a single piece of 6061-T6 billet aluminum. That means it s tough and lightweight 64% lighter than the stock pulley, to be exact. This reduction in weight cuts down on rotational inertia and parasitic loss, so you re getting better performance without the unnecessary bulk. Plus, it s black anodized, which not only looks sleek but also resists corrosion. No one wants their upgrades to look worn out after a few months.

Installation is a breeze, especially if you re just swapping this in as the sole pulley upgrade. It pairs nicely with the Dynamic+ B8/B8.5 3.0 TFSI Performance Software Stage 2 tune. If you decide to go all out and combine it with the upper pulley, then you ll want to step up to the Stage 2+ tune for optimal performance. It s all about getting the right balance, and this pulley helps you do just that.

Key Features:

• Single-piece construction from 6061-T6 billet aluminum for strength and durability.
• Black anodized finish with laser engraving for a clean look and resistance to wear.
• 64% lighter than the stock pulley, which means less parasitic loss and better efficiency.
• Complete inner and outer pulley design no overlay nonsense that adds weight.
• Perfect for an easy Stage 2 install or as part of a more extensive upgrade with the upper pulley.
