color:#1F497D'>The hot running oil pressure of 100 is a little high and you can
change this with modifying the bypass spring pressure. The cold starting
oil pressure issue is more of a concern to me. Are you by chance running
an oil cooler without a thermostatic valve? Different brands of cooler
take off heads circulate the oil in various manners depending on how the
by-pass is engineered into the filter head.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>New
motor. 12:1 comp. 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>
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>
My concern is the cold oil psi fluctuation and the higher than previous high
rev psi.<br>
<br>
Thoughts please. Before I tow it to northern VT for hill climb next week.<br>
Thanks, <br>
Brian <br>
