High quality designed springs is required to transfer the exact movement of the camshaft to the valves at high engine speeds on high performance engines. The TOMEI products are always engineered with precision in mind to suit the user's needs. So with this in mind careful choices in material selection is made with surface coating and other technologies. Then the pre-production products are put through an extensive testing program for checking durability, quality and performance. We spend time and money to help you save your valuable time and money.

Features:

  • Multi Coil Unequal Pitch Springs- By combining several steps of spring rates into the one spring and vibration frequency becomes amazingly high. This greatly minimizes resonance and the chances of surging.
  • Advanced Oil Tempered Chromium-silicone Alloy Steel Core- Oil tempered chromium-silicone alloy steel wire is used which is considered to be the best material for springs for performance applications and evolved it even further. Combined with a new optimized design, not only did we make it tougher, we also succeeded in suppressing valve jumps or bounce even when raising the engines speeds RPM limit.
  • Nitriding- The surface treatment method for making nitrogen permeates the spring and gives it large surface compression repulsion. This method was chosen to raise the fatigue limit to suit the demands or running high lift camshafts. The dangers of spring failure is greatly reduced with the 1.5 times increase in the springs fatigue limit with the combined use of Oil tempered chromium-silicone alloy steel wire and Nitriding. This is how our valve springs are suitable for use on extreme engine speed conditions of super-high revs exceeding 10,000 RPM which had not been previously possible with high lift camshafts.
  • Shot Peening-A process that strikes many small steel balls onto the surface of the spring at high speeds is made to enhance the surface of the spring to raise its fatigue limit. Although it has been carried out earlier during the manufacturing process.
  • Warm Setting- The process that is adding higher loads beyond the actual limits to the highly heated spring. This will modify its shape and keep it permanently fixed. We succeeded in securing the highest performance over a long period of time while preventing sagging.
  • Oval Wire- Using highly durable oval wire allows the valve springs to compress even further whilst still retaining sufficient force. Compatible with many high lift camshafts, these springs provide reliable performance even under load at higher RPMs. Oval wire valve springs feature greater compression than regular valve springs, allowing them to work with a wider range of 'lift' settings. This makes them compatible with both stock AND aftermarket high lift camshafts. (VR38/VQ35/KA24/4G63/4B11/G4KF)

Creative Call a Great Adventure
Format: Paperback
I was looking for a book that would encourage me to move forward on my creative journey. I love to journal and make paper crafts (including handmade books and cards), but I've never really seen myself as an artist. I was also looking for a Christian tool, because the philosophy is so different. This book is perfect! I'm enjoying the exercises and I'm reminded that God created us in His own image. He is the Creator and I am a co-creator (imagine that). This book is helping me with my daily devotions and I'm moving forward with more artistic pursuits. For those who are looking for a way to improve their relationship with God, and find out how God wants to create through you, this book is immensely useful. It includes scripture and thought provoking exercises. I hope you enjoy it as much as I have.

I teach art all the time, everywhere
Format: Kindle
Janice E. is correct in explaining a creative outlook. It's absolutely part of human existence because of who God is, what he has done, and continues to do. This Pandemic has brought home a fact to me. Whatever tries to control our membership in the human race better learn it cannot totally destroy our spirit. I connect the beginning of my day with prayer and writing a short letter to God where I can ask anything and I can then watch for his answers. Then I seek how I might do creative pieces. Yes, it takes perseverance to excell but the spirit that is creative needs to step forward. Janice E., good job by your warmth and friendly encouragement.

Amazing!
Format: Paperback
I had a desire to write but nothing would come to me. Then, I began to read this book. It was a game changer! Three chapters into this book and I began to see scenes in my head for a story I am now writing. It all started to flow out of me and I credit this book for getting that started. Journeying through this book also strengthened my faith and validated that taking time for my talent is not selfish, it’s a form of worship. I highly recommend this book!
