What would happen if you went to 8-10psi

What would happen if you went to 8-10psi

i really dont want to have to run meth and wanna keep iats down. you could do 10 psi on meth but dont want to be meth dependent. 10 psi on this truck with meth would prob do 650-675 rwhp

i have a 16 c7 z06 and just picked up a 16 ss which im doing heads/cam/nitrous on so those will be my fast cars

What size pulley are you running? Have you used a boost gauge? We have seen a lot of Whipples ship with an 8 psi pulley but they claim 6. Our SS makes 6psi and shipped with a 4" pulley.

Mechanical old Stewart warner gauge. I'm pulling off blower do swap pumps then do zr1 map sensor so I can run off aeroforce gauge.

Daym . All that power on demand. Ever since sc install, I've been a little more throttle heavy. Crusts because I'm always tryin to hear the sc whine

Tony...refresh my memory...is your Escalade AWD or 2WD?

Damn...with those numbers you're going to be breaking the hearts of a few local "Power Stroke", "Duramax" and "Cummins" Ram runners in your area !! I would love to be riding "Shotgun" shooting a video with you when you sneak up on one of them on the DL and kick them to the curb !!

Tommy Hoffstetter at Chief Engines is a friend and he and I have pondered the idea of setting up your same combination for twin installation in boats. Big Blocks are getting to be tougher to come by and with LS TQ numbers over 600# at the crank it is becoming a viable alternative.
