The SPOOLOGIC Non-EBPV Turbo Outlet Plate SL-370-002 is a direct-fit EBPV-delete outlet plate for the 1994-1997 7.3L Powerstroke — solid plate with no butterfly, no actuator rod, and a clean exhaust path from the turbine housing to the downpipe. Ships with 4 SPOOLOGIC yellow Viton pedestal O-rings and 3 M8 12-point plate bolts. Backed by a 1-Year Limited Warranty.

This is the outlet plate for EBPV-delete builds — trucks running an aftermarket exhaust brake, a compound turbo setup, or any performance build where the OE EBPV butterfly has been removed. The Non-EBPV plate has no moving parts inside the exhaust stream. The butterfly is deleted. The actuator rod is deleted. The bore where the rod would pass through is plugged. The result is a straight-through exhaust path that eliminates a known failure point on high-mileage trucks. The SL-370-002 pairs with the SPOOLOGIC Non-EBPV pedestal (SL-340-004) or is used as part of the SL-340-007 kit.

Why You Delete the EBPV

The EBPV system was designed to speed up cabin heat and engine warm-up on cold-start. It works fine when it's new. On a 20+ year old truck, the failure modes stack up fast:

• Seized butterfly — carbon buildup and thermal warpage seize the butterfly shaft in the bore. A seized butterfly stuck closed is a permanent exhaust restriction that kills top-end power.
• Bent actuator rod — the rod that connects the pedestal-mounted actuator to the butterfly bends from vibration and thermal fatigue. A bent rod binds mid-travel.
• Failed pedestal-mounted actuator — the hydraulic actuator that moves the butterfly seizes internally. The butterfly stays wherever it was last commanded.
• Interference with aftermarket exhaust brakes — the OE EBPV butterfly interferes with the operation of an aftermarket exhaust brake mounted downstream. Delete the EBPV and the exhaust brake works as intended.

Deleting the EBPV eliminates every one of these failure modes at once. The SL-370-002 is the plate that does it — clean bore, no butterfly, no rod, and matched to the SPOOLOGIC Non-EBPV pedestal so the whole assembly bolts up as a matched pair.

Component Breakdown — What's In the Box

• SPOOLOGIC Non-EBPV outlet plate casting — new aluminum outlet plate with the plate-to-turbine-housing bolt pattern for the 94-97 TP38 housing (3-bolt pattern). No butterfly bore. No actuator rod passage.
• 4 SPOOLOGIC yellow Viton pedestal O-rings (SL-310-001) — 2 large and 2 small yellow Viton O-rings that seal the outlet plate to the pedestal. 400°F continuous service rated.
• 3 M8 12-point outlet plate bolts — the 94-97 outlet plate fastens to the turbine housing with 3 M8 12-point bolts. 12-point drive gets purchase in the shallow counterbore where a hex socket can't.

Material Technology — Why Each Material Was Chosen

• Aluminum outlet plate casting — precision-cast aluminum, dimensionally matched to the OE plate on the turbo-facing side. Aluminum sheds heat fast enough to keep the plate flat under thermal load.
• Yellow Viton fluoroelastomer O-rings — industry-standard fluoroelastomer for hot oil service. 400°F continuous, 500°F intermittent.
• M8 12-point plate bolts — grade-appropriate alloy steel with a 12-point drive head. Sized for the counterbore in the turbine housing.

Install Notes

• Do not reuse the yellow O-rings. Every installation gets fresh SPOOLOGIC yellow Viton O-rings from the kit.
• Clean the turbine housing outlet mating surface before installing. Any carbon or old gasket material will prevent the plate from seating flat.
• Torque the outlet plate bolts in a criss-cross pattern to spec. Uneven torque warps the plate and leaves an exhaust leak.
• Verify the pedestal-side EBPV actuator is either removed or terminated before running the truck. A live actuator with no butterfly to drive will throw a code and dump oil into the (now-deleted) EBPV oil passage. Use with the SPOOLOGIC Non-EBPV pedestal (SL-340-004) or an OE pedestal with the EBPV terminator installed.
