Mitsubishi Evo X +1mm Intake Valves by GSC Power-Division

When creating our new valve line we set out to create the best performance, longest lasting valves available to the aftermarket. Using advanced 3D design and simulation software, we have created a stronger and higher flowing valve head design.

We flow test prototype valve heads in the specific applications to make sure we have the highest flowing valve head available on the market today. With the materials used, we have less valve distortion at the face than any of the tested designs. Less distortion allows for better sealing under extreme conditions and more consistent performance throughout the life of the valve.

GSC Power-Division's new valves are sure to become the industry standard for sport compact performance valves.

Features

  • Swirl polished heads for smoother air flow over the valve
  • Back cut to reduce valve weight for higher RPM, higher boost pressure, and allow for more aggressive cam profiles without increasing valve spring seat pressures
  • Valve stems are micro polished to allow for less oil retention on the stem, which creates less drag on the stem to guide for a smoother motion
  • Intake valves are a modified 21-4n stainless and exhausts are a modified 23-8n stainless material for high heat capacity while maintaining longevity
  • Valve tips are either hardened or have a stelite wafer tip fused so that the tip is within 5 Rockwell C of the rocker or valve tappet for extended life and less wear
  • Valve tip lengths - we have taken extra time to adjust tip heights on the applications to require less tipping of the valve, to maintain proper tip height for proper valve train geometry, and to cut down on install times when setting valve lash
  • We have also adjusted the keeper groove to properly balance intake and exhaust spring pressures to reduce the use of valve spring shims and maximize performance from our spring and retainer kits
  • Valves will work with an OEM keeper/lock or, when available, our upgraded keeper/lock. It is not mandatory, but it is suggested, that any valve lock not be reused on performance applications due to material grooving

Excellent little grinder
For the price, this thing is a great value. I wanted to use it a bit before writing a review, because anything can be amazing initially. I have been using it for several weeks now and let me just say that for the price, you get a great little grinder. This thing isn't meant to grind up bags and bags of coffee, but for grinding a nice little bit for a few days at a time, it's perfect. It's easy to set the grind level / coarseness, and it "stays" where you put it. I have not had any issues and it seems pretty durable. I saw some complaints of it being slow, but maybe they just expected electric speeds with a manual grinder? Not sure, but for me I am able to grind a full reservoir (the container of this item) in less than a minute and a half, at best. I got this because sometimes I am lazy and didn't use the electric grinder the night before and I don't want to wake up the wife grinding my coffee, so this is PERFECT. The only thing is, now I don't use my electric grinder anymore.. The reason for that is I get more consistent ground coffee using this little guy than my electric grinder ever has. So now I am stuck in manual mode, and for cheap! This thing is super light and easy to store away, not bulky and won't get in your way. So if you are hesitant because you saw some bad reviews, just do what I did.. buy it anyway and find out for yourself. I have learned that most negative reviews on Amazon are because people expect things to be more than they are or to somehow function beyond their capabilities... This thing does what it's supposed to do, and it does it well. So buy one now, you won't regret it!

Gets it done.
At this price point it is a excellent grinder for coffee. It does adjust for different grinds but there is no scale to gauge, just clockwise or counter clockwise. Recommended if you are not sure if you want one.
