Around 10lbs and that should be good for 580-600rwhp.

Parish was running about 16psi at one point I believe. He was also running 13psi +75HP shot in his Silverado and it held up fine. He didnb't hurt the motor till a nitrous noid stuck open in the staging lanes.

if you run good fuel and stay out of detonation you can max that turbo.

i ran the stock 4.8 up to over 20psi and the 6.0 up to what F8L said. i ran both motors for awhile at those settings.
