Granatelli 44mm Piston-Actuated External Turbo Wastegate with V-Band - 540261

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.

Why This 44mm Turbo Wastegate?
