4.8 turbo dyno numbers
dyno' d my truck today at xessive, truck made
674rwhp@6442rpm /573 rwtq on boost only tryed spraying 50 shot but turned it off around 5800 rpms cuz it was leaning out truck was peeling off when it was doing the dyno pull so it should be more power than what it read not bad for a stock bottom end 4. 8 litter with some boost i guess we need to upgrade the stock fuel lines to a -8 an line so it can feed the hungry little 4. 8

Good to know I still got some head room. What fuel you running? Great numbers bud, I'm sure the tq graph looks good if you hit it with a 50 down low. Look forward to seeing the graph and new 1/4 mile times. I'm thinking some 10.5-10.6x

Right now its at 18psi, we gotta fix the fueling issues and make some passes on 18psi and the nitrous. Setup is a stock 4.8, stock heads and bolts, 90mm tb with 07+ intake, 220/220 cam transmission is a stock 4l80e on stock converter.
