Message: [QUOTE="TARM, post: 115516, member: 578"] The ramp rates on the stage II cam specd by Matt are the reason for the higher spring rate. But I do not agree with the idea that if 150 is what is needed then 175 is some how ok or better. Whether that ends up being the case or not that is flawed thinking. The higher the spring rate the faster the wear rate. Not to mention it takes more energy and friction so unless their some positive return..... . How exactly are you guys coming up with a 92 and 72 pound seat pressure for the 910 and OEM respectively? I think making the assumption that if 150 is the needed seat pressure for a cam that more or 175 would some how be better as a general process of reason is flawed. More seat pressure than needed equals excessive wear, increased friction and energy expense. What is the real world gain to be had to offset the cost? What does going from 150 to 175 get you? 7K with HUEI when our injections system with current openly fielded parts has barely broken 4K [/QUOTE]
