Supertech Performance BMEVN-1030 BMW S42 / M42 / M50 / S50 / M52 / S52 / M54 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 - 30.50mm (STD)
  • Length - 105.65mm
  • Material - Black Nitrated
  • Stem Diameter - 5.96mm


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.

My daughter loves this for Roblox
Color: A-Pink
This 11th gen iPad case with keyboard is exactly what I needed. The case feels sturdy and protective without being too bulky, and the keyboard connects instantly with no lag. The keys have a nice, comfortable feel—much better than I expected for a compact keyboard. I love that the case has multiple viewing angles and holds the iPad firmly in place. The built-in keyboard makes typing so much easier for work, school, or travel, and the battery life lasts a long time between charges. Overall, it’s a great all-in-one setup that turns the iPad into a mini laptop. Excellent quality, great fit, and definitely worth the purchase!

Wrong size iPad? No problem
Color: A-Pink, Color: A-Pink
I want to start this review by saying that I forgot to check that my iPad was a 10th generation before buying. Sadly my iPad is not a 10th it’s a 9th generation. This means mainly that it’s slightly smaller than what this case was designed for. However I can happily say that I didn’t run into any issue because of this. The only thing is the sound buttons don’t work, but that’s fine with me cause I don’t use sound on my iPad. It honestly fits really well too, it’s only like a half inch of space in the case that my iPad didn’t fill. The keyboard does feel a little cheap but other than that it works perfect. 5/5 cause despite my error is still works perfectly for me.
