How much faster does the APR Supercharger Drive and Crank Pulley Kit spin the charger?

Together the pulleys spin the supercharger about 26.4 percent faster than stock. The APR Supercharger Drive and Crank Pulley Kit pairs a 57.75 mm drive pulley, worth about 9.5 percent, with a 187 mm crank pulley, worth about 15.4 percent.

Do I need software for the APR 3.0 TFSI pulley kit?

Yes. APR states that specific software is required to maximize output with these pulleys, and it is sold separately. The faster supercharger makes more boost, and the calibration has to be set up for it. Contact us with your vehicle details to match the right software.

Should I add the APR Ultracharger throttle body with the pulleys?

To use the full dual pulley setup, yes. At the airflow the pulleys create, the factory throttle body becomes the restriction. APR sells Ultracharger throttle body upgrades for the B8 S4 and S5, the Q5 and SQ5, and the C7 A6 and A7.

Does the APR S4 crank pulley replace the harmonic balancer?

No. The APR crank pulley bolts on top of the factory harmonically balanced pulley, so the balancer stays in place. It is machined from billet aluminum with weight saving pockets, anodized black, and supplied with a set of new crank pulley bolts.

What tools do I need to fit the APR SQ5 supercharger pulley?

The factory drive pulley is pressed onto the supercharger, so removing it needs the APR pulley removal tool MS100025, sold separately. The new drive pulley is pressed on, and APR supplies instructions for both the drive and crank pulley installs.

Description

APR Supercharger Drive and Crank Pulley Kit for 3.0 TFSI

The APR Supercharger Drive and Crank Pulley Kit spins the supercharger on the Audi 3.0 TFSI V6 about 26.4 percent faster than stock, raising boost and lifting horsepower and torque across the rev range. A smaller press-on drive pulley and a larger bolt-on crank pulley share the job, and the correct belt is included. APR chose the speed after extensive engine and chassis dyno testing with different pulley sizes, and specific software is needed to make the most of it.

Drive Pulley

The drive pulley drops from about 63.25 mm to 57.75 mm, spinning the supercharger about 9.5 percent faster on its own. It is CNC machined from billet stainless steel, e-coated black for a factory look and press fitted to the factory supercharger.

Crank Pulley

The crank pulley grows from about 162 mm to about 187 mm, worth about 15.4 percent more charger speed. It is CNC machined from billet aluminum with weight saving pockets, anodized black, and bolts on top of the factory harmonically balanced pulley with new crank pulley bolts.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
