VAC Forged Stainless Steel Valves are precision made to exacting
specifications and are suitable for both street performance and
full Race vehicles.
Our valves have been proven to work great in street vehicles for
day to day use where engine build up and byproducts can harm
typical "race valves", yet these valves have proven their worth on
max performance all out race engines, surviving lap after
lap, race after race, and even multiple seasons without being
replaced!
As the M50 and M50 engine are under 3-litters, they typically
breath fine with most camshafts on mild builds, but since the S50us
and S52us sepc M3 engines use the same heads and valves, we have
found
great gains when fitting even mild S50 and S52s with
these better flowing, and lighter weight valves.
Our valves feature:
- One piece forged stainless steel design (compared to 2 piece
welded valves which typically fail at weld)
- Use of original 3 groove keepers/locks for direct replacement
(1995 and older engines are recommended to be fit with our upgraded
locks by default)
- Lightweight engineering: enhances performance and increase
valve train component longevity
- Low-friction coated to preserve valve guide bore
- Enhanced resistance to fatigue from heat and high RPM
VAC Tech Tips:
-These valves are a must-have when building a high performance and
very high revving engine: They dramatically reduce valve weight and
this improves valve train reliability greatly as the valve springs
do not have so much mass to control. Crucial on the M50 family of
engines like these.
-Over-sized valves can help enhance maximum engine output, a great
upgrade with 264/256 and larger cams.
