I put my new mill on the dyno and at idle I have 75 psi and at WOT it goes to 100 psi. I'm running 15W-40 Rotella T in it so I'm thinking about switching to a 5W-30 or something to get it down. I like the Rotella T but they don't make it in a 5W-30 or maybe I should try a synthetic??? It's a 700 HP small block that spins to 7200 rpm's and used on the strip only. It's in the car already and I don't wanna pull it out to mes with the pressure spring either... Any suggestions are greatly appreciated!!!
