Supertech Performance BMEVI-1045S BMW M3 S54 Exhaust valve

Supertech valves are the best on the market, made from one piece of forged stainless steel for the ultimate in strength and durability. Supertech valves go through a special heat treatment process that obtains the right amount of harness for each engine to ensure the ultimate valve for your performance motor. Supertech offers their valves in either chrome coating, used in high performance valves, or hardened black nitrided which is most popular in European and Japanese motors.

Specs:

  • Head Diameter - 31.50mm (+1.0)
  • Length - 119.10mm
  • Material - Inconel
  • Stem Diameter - 5.95mm
Note: Must be used with single groove keepers KPR6S/7


Supertech High Performance Race Engine Valves features:

  • The microhardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer (microhardness is 800HV minimum)
  • Surface finish is smoother than with chromed stems, having less friction between stem and guide.
  • Valve seat surface is harder with the nitrided layer, lasting longer with lead free fuels, alcohols, nitro or other "explosive" mixes. Matches any kind of seats (nodular iron seats, steel powder metal seats, hard aluminum-copper seats or beryllium copper seats).
  • Higher rpm's engines take full advantage of all previous features. The higher the engine speed the bigger the power loss due to internal engine friction! The black nitride layer reduces this power loss due to less valve-guide friction.
  • The nitrided layer is adhered to the base material at a microscopic level, so does not"flake" or brake when the valves bend due to impacts with the pistons.
  • The Black Nitride applies to the whole valve while the chrome coating is only applied to the stem.

A Classic
Format: Paperback
This is my favorite book by Dr. Watson. I have read it many times and continue to learn and deepen my own nursing practice. I highly recommend this book over all others. Whether you've been a nurse for 4 years or 40 years, you'll be surprised at what you'll learn.

Caring- updated.
Format: Paperback
It is refreshing to read The Philosophy and Science of Caring. Caring is central to nursing and frequently in the nursing literature. Watson has revised and expanded her Caring Science and Philosophy, offering new insights,science and exemplars. This book is useful for all nurses,scholars, practitioners and educators. It should be required reading for nursing regardless of practice venue. Bravo, Jean!

Good for research
Format: Paperback
Nursing research is not the place for me but it’s good to know this stuff before you become a nurse. I did use this for many assignments.
