COMPACT PISTON BOOST CONTROL. PISTON CONTROL WITHOUT THE FOOTPRINT OF A BIG 50 OR 60MM GATE. The Granatelli 540261 44mm external wastegate combines compact packaging with a piston-actuated boost-control design for custom turbo systems where engine-bay space matters. It gives street, street/strip and race-car builders a durable 44mm V-band turbo wastegate without using the diaphragm architecture found in Granatelli's water-cooled wastegate line. 44MM Compact Valve / PISTON Actuation Style / 5 SPRINGS Boost Tuning. Why This 44mm Turbo Wastegate? The compact 44mm size is easier to package around turbo manifolds, headers and exhaust plumbing while still providing external exhaust bypass control for many performance turbocharger systems. Product Specifications: Part Number: 540261; Product Type: External Turbo Wastegate; Valve Size: 44mm; Actuation: PISTON-ACTUATED; Top Cap: Black Anodized Billet Aluminum; Base: Stainless Steel; Mounting: V-Band Inlet / Outlet; Included: Flanges, Clamps & Five Variable-Rate Springs; Cooling: Air-Cooled (No Water Ports); Air Ports: 2 on Actuator Housing - Barbed Fittings & Port Plugs Included. Key Features & Benefits: Application-focused Granatelli Motor Sports design; Built for dependable performance and service; Designed for enthusiasts, professional installers, and performance builds. Fitment & Installation: Confirm the part number, vehicle or engine application, dimensions, and supporting components before installation. Modified vehicles may require additional clearance, fabrication, calibration, or related hardware depending on the combination. Frequently Asked Questions: Is the 540261 a piston or diaphragm wastegate? The 540261 is piston-actuated. It uses a mechanical piston instead of a flexible diaphragm to open the valve. It is a different part from the 44mm water-cooled diaphragm wastegate, Granatelli 540244, so check the part number, not just the size, when you order. Is the 540261 water-cooled? No.
