PMO 50mm Triple-Throat Carburetor Kit for Porsche 911 3.6-4.0L (Race) | PM-O808-0

PMO 50mm Triple-Throat Carburetor Kit for Porsche 911 3.6-4.0L (Race) | PM-O808-0The PMO 50mm Carburetor Kit is the ultimate induction setup for big displacement air cooled Porsche 911 builds 3. 6L stroker motors, 3. 8L race engines, and 4. 0L+ all out builds. The 50mm size was never offered by Weber (which topped out at 46mm with a restrictive throttle plate enlargement). PMO designed and manufactures the only true 50mm air cooled Porsche carburetor in the world. Made in Anaheim, California by EMPI. Kit Includes Two PMO 50mm

The PMO 50mm Carburetor Kit is the ultimate induction setup for big-displacement air-cooled Porsche 911 builds — 3.6L stroker motors, 3.8L race engines, and 4.0L+ all-out builds. The 50mm size was never offered by Weber (which topped out at 46mm with a restrictive throttle plate enlargement). PMO designed and manufactures the only true 50mm air-cooled Porsche carburetor in the world. Made in Anaheim, California by EMPI.

Kit Includes

• Two PMO 50mm carburetors (jetting per application — performance baseline)
• 43mm chokes (typical), 185 main jets, 60 idle jets
• 190 air correction jets, F2t emulsion tubes
• PMO throttle linkage
• PMO fuel pressure regulator
• Carburetor isolators
• Complete hardware and fuel hose

Why 50mm Over 46mm

For engines over 3.4L, a 46mm carb becomes a restriction at peak RPM. The PMO 50mm has 8.6% more throttle area — significant on engines breathing more than the original 911 designers planned for. This is the carb of choice for serious 964 / 993 stroker builds, hot-rodded 3.6L motors, and outlaw race engines.

Why PMO Over Modified Weber

• Weber never made a 50mm air-cooled Porsche carb — period
• "50mm" Weber conversions are 46mm bodies with bored plates — restrictive top end
• PMO 50mm is a true 50mm throttle bore from top to bottom
• One-piece stainless throttle shafts with ball bearings — no air leaks
• Float bowl sight glasses for tuning without disassembly
• Aerospace-grade billet construction

Fitment

• 1965-1998 Porsche 911 / 914-6 / 964 / 993 with 3.6L+ engine
• Best for stroker, big-bore, and race applications
• Requires appropriate intake manifolds — PMO 50mm billet manifolds sold separately
• Hood/decklid clearance — verify before ordering for early 911 chassis

Made in Anaheim, California

EMPI-manufactured at PMO's California facility. Same engineering Richard Parr developed. Now backed by EMPI's investment in expanded machinery.

Note: 50mm is a serious carb for serious builds. Not recommended for stock or mildly-built engines below 3.4L — the 46mm or 40mm kits will make better power on smaller motors.

Installation: Final jetting must be tuned to your specific build. PMO Carb Setup Sheet required. Professional dyno tuning strongly recommended.
