At cold start up oil pressure fluctuates from 20-60psi. Once warm (approx 180 deg Fahrenheit) pressure is consistent with rpm increase. At idle hot is 60psi. Upwards of 100psi at 5000rpm. 5-7k is were it will rev during race condition. <br class="">Now FYI - this is the first motor by the book with precise measures. Previously it's been "well this is what I can afford" . Getting older and get tired working the wheel so thought I'd try something a little different. <br class="">My concern is the cold oil psi fluctuation and the higher than previous high rev psi.<br class=""><br class="">Thoughts please.
