My LS3/525 is holding about 35# of pressure at 950-1000 rpm hot (185-190*) idle. Off idle it climbs fast and reaches 65-70 psi at higher rpm's! Wondering if this in normal! Have not been on the board in awhile! Got my Cobra Kit Car on the road 5-6 months back, got about 600 miles on it! It does Scoot, I hit 121 mph putting it on a 1000cc Sport Cruise Suzuki, not even close!

Thanks Al

Your pressures are quite normal, even better than average.

Thanks, first LS so I wasn't sure! I be liking it! Still need a better intake tube and a tune but so far so good!

Mine was a new crate LS3/430HP. I see 35-40 psig at 210F oil temps at 675 rpm. Perfect.
