On a performance engine under load I'd prefer 120-140 water temps. Your oil temp is perfect.
Be careful with t-stats with your type cooling system - they can make water psi get destructive. I have personally seen things get nasty (ie:water leaks where you really don't want to see them) at 30+ psi. I tested a crossover system with t-stat on the dyno that went over 60 psi ! Results where enine teardowns. Therefore, 25psi is all I'd ever want to see and still feel comfortable.
Thank you for the response. Your help is appreciated.
Can anyone suggest a method for me to increase my water temps from 95 to 120-140 range without the use of a thermostat. My concerns with running a t-stat are exactly as Cfm stated and I really want to avoid having to run one.
