do88 Performance BigPack Intercooler Kit for 992.1 Porsche 911 Carrera and 911 Dakar [BIG-310-C/BIG-310-SD]

The do88 Performance BigPack Intercooler Kit for the 992.1 Porsche 911 Carrera is engineered to deliver maximum cooling efficiency and performance. Featuring high-quality Garrett Motorsport cores with thin, stacked fins, the kit optimizes cooling and airflow. Lightweight cast aluminum end tanks provide efficiency without added weight, while premium carbon fiber air ducts accommodate the thicker core with exceptional durability and fit. Enhanced intercooler connections and custom-designed do88 silicone hoses with smooth bends eliminate airflow bottlenecks. Every aspect of this kit has been meticulously developed without compromise, offering unmatched performance for the 911 Carrera.

Background

Earlier versions of the Porsche 911 housed intercoolers inside the rear fenders, connected by a Y-pipe that directed charge air to the inlet manifold. The 992 introduces a completely redesigned setup, combining the intercooler and Y-pipe into a single unit beneath the rear wing. Ambient air is channeled from the rear window into a scoop on the decklid and through the intercooler core for optimal heat transfer. The active rear wing plays a critical role in this design, directing additional airflow when in its upright position. While this configuration is more efficient, it also presents new challenges for performance cooling manufacturers. To accommodate a core with greater volume and surface area, do88 developed new carbon ducts to allow increased thickness. These advancements in carbon production ensure a fit and finish that align with the iconic status of the Porsche 911.

Garrett Cores

The intercooler cores are Bar & Plate, sourced from Garrett Motorsport, a leader in performance cooling. With thin, stacked cooling fins, these cores offer dense construction for highly efficient heat transfer. Measuring 105 mm (4”) thick, they maximize available space for this application. Air is evenly distributed through freeform-designed cast end tanks, a product of extensive 3D scanning, CFD analysis, and iterative 3D prototyping. Cast end tanks allow for intricate shapes that CNC machining cannot achieve, prioritizing function over aesthetics to ensure maximum airflow. Each tank includes machined 70 mm (2.75”) connections to support high outputs, paired with silicone hoses for optimal performance. Both cores connect to a central outlet tank leading to the inlet manifold, complete with machined connections and meth bungs.

Carbon Air Guides

The air guides are made from vacuum-infused prepreg carbon and feature fastening grooves for air channels, replicating the functionality of OE components. Despite their complex shapes, these guides ensure precise fitment. The upper air guides remain consistent across all models, but the lower pieces come in two versions: Standard or SportDesign. SportDesign ducts, designed for better air evacuation through a central outlet in the bumper, offer superior performance, though do88 provides carbon ducts for both configurations. Proper rubber seals prevent air from bypassing the core, ensuring maximum cooling efficiency.

Aluminum Pipework

The BigPack includes do88 intercooler pipework, an upgrade over the stock hoses. These pipes are crafted from mandrel-bent 63 mm (2.5”) aluminum and finished with a satin black powder coating for improved airflow and durability. The kit also includes four silicone hoses, with turbo outlet hoses made from high-temperature material rated to 240°C (464°F) continuous heat. “Constant tension” hose clamps are used at these positions to accommodate thermal expansion, ensuring reliability under extreme conditions.

Performance

The do88 intercoolers provide a significant reduction in intake temperatures compared to the OE 992 units. During testing, conducted on a closed airstrip, five consecutive full-throttle runs from 50-250 km/h (30-155 mph) were performed in a Porsche 911 Carrera S (450hp) with no cooldown between runs. The active rear wing remained in its upright position throughout the test. The do88 intercoolers demonstrated a peak temperature reduction of 9°C (16.2°F), as shown in the data graph. This improvement reflects the product’s superior heat transfer and airflow efficiency.

Testing

Testing involved five runs with the OE 992 intercoolers, followed by a rapid installation of the do88 intercoolers and another five identical runs. The results showed a significant decrease in inlet air temperature, with a peak difference of 9°C (16.2°F). Verified using the Superflow SF-1020 Probench, the do88 intercoolers demonstrated superior airflow and heat transfer efficiency compared to the OE units, delivering reliable and proven performance.

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.
