Granatelli Motor Sports Water-Cooled Diaphragm Wastegate – 60mm
SKU: 540259
Engineered for Maximum Stability, Cooler Operation, and Rock-Solid Boost Control
When you're pushing serious boost, heat becomes your biggest enemy. Granatelli’s water-cooled diaphragm wastegate eliminates that weakness by circulating coolant through the diaphragm housing, keeping temperatures stable and performance consistent. The result? Harder runs, tighter regulation, and a wastegate that doesn’t flinch when the heat is on.
Designed for drag racing, high-performance street use, and heavy-hitting diesel setups, this 44mm wastegate delivers the reliability and precision your build deserves.
Water-Cooled Diaphragm Advantage
Traditional wastegates struggle as temperatures climb. This water-cooled diaphragm system stays thermally stable under extreme exhaust heat, giving you:
- Consistent boost control on hot laps
- More accurate boost regulation
- Longer diaphragm life
- Reduced boost creep in high-heat environments
A black anodized billet aluminum cap and a natural-finish stainless steel base complete a design built to take abuse without missing a beat.
Straightforward Installation & Full Adjustability
Installation is simple with the included V-Band inlet and outlet flanges and clamps. The wastegate comes with two pre-installed springs—4 PSI and 5.7 PSI—giving you a ready-to-run baseline right out of the box. Wastegate includes inlet and outlet flanges with clamps and a spring kit. The spring kit contains five springs: One inner spring 5.7 psi (30mm dia. X 64mm tall) and an outer spring 4.0 psi (38mm dia. X 64mm tall) installed. Three additional springs are included, Red is 4.5 psi (28mm dia. X 60mm tall), Yellow/Orange is 12 psi (48mm dia. X 100mm tall) and a Green spring, 6.5 psi (58mm dia. X 78mm tall). These can be can combined for the desired boost levels. Also includes water line fittings.
The additional springs in the Five-Spring Kit include 4-5 PSI, 6-7 PSI, and 12-13 PSI options. Mix, match, and stack to achieve your exact boost pressure. No guesswork. No compromise.
