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)

Started off great, but kind of went left.
Format: Kindle
I liked the first few chapters. The introduction of the book have an INCREDIBLE acronym to remember the drug classes. I liked him pointing out stems because they are very helpful, BUT some of the hints and connections could've been better. Also, the book doesn't help memorize the brand/generic name. It only helps remember what drugs go into which drug classes which could be done simply just from knowing your stems. So you're right back at square one trying to remember the brsnd/generic name like you were in the first place.

Makes memorizing 200 drugs look easy!
Format: Paperback
I really liked this book. I liked how this book broke up into 7 different sections (gastrointestinal, musculoskeletal, respiratory, immune, neuro, cardio, endocrine) this made it easier to understand. I also thought that Guerra did a good job of explaining what other students found helpful in memorizing these drugs, it was something that I could relate to and found this really helpful. I also really liked at the end of the chapter, how the book gave quizzes at the end of each chapter, this really helped me to retain the information and make sure I understood what the drug really was. Overall, this was a great book and I would recommend this book for anyone taking pharmacology. 200 drugs can be difficult to understand but I thought this book did a good job of memorizing the drugs.

Great for explanation of difficult concepts, with review questions each chapter
Format: Paperback
I always thought I could never understand pharmacology, so going through my Acupuncture school, I got though my pharmacology courses by rote memorization and pure luck. Then, in practice, I realize that I do have to understand pharmacology, what with the high use of medication in patients' daily routine. So I was looking for a hood, concised, simple to understand pharmacology review that I can do a quick study/review on my own time. Thankfully, I found the right book. This book is everything I've been looking for and amazingly simple to understand. I love the review questions at the end of each chapter. I wish I had found this book while in school, but for $20, it's really help me understand why my patients are taking certain drugs. It also helps me understand the western deconstruction of the Chinese medicinal herbs. I wish they'd come out with a pharmacy review just for Chinese medicinal herbs and potential contraindications, just for acupuncturists and herbalists. The current available herbal medicine textbooks just pretty much list the herbs and note western research on it, but not much of an explanation. With age, I find that I can no longer just do rote memorization, so understanding the basics really helps me to remember and apply concepts. I use this book in my clinic concurrently with a textbook on Chinese medicinal herbs pharmacological concepts to help me understand. And for that, I give it the five stars it deserves.
