626hp 800+Tq!!
626hp 800+Tq!! Recently purchased a 98 mistic teal z28 for a steal.
Car was already set up with a 5.3lm7 built t56 and on3 76mm turbo with and fmic. Car ran a little rough when I got it(exhaust leaks at collector) and it was only on a street tune to make it run.
So I immediately took the car to LMR not even 4 hours after buying the car.
After all said and done problems ironed out and tune where I should be, it late down 626hp and 800tq @12 psi.
I can't believe how much power these 5.3's will make with minimal effort on a budget build. Ill be putting meth on the car later and ill be praying the 10 bolt holds together!

Good numbers op.
From my experience 14psi is just about it. That baby 65mm turbine exducer can only flow so much. I went with a knock-off magnum 80mm that has a 77.5mm turbine exducer. I havent put it on yet but It should be all the turbo I need on this 5.3. Alot of guys run the T4 S475 or the PT7675 with great results. Turbonetics also just cam out with there version of the 7675 and a 7875 that should fit exactly like that on3 fits. May want to look into that

Here is a video from a few days ago. Go to about a minute into it. The boost guage is on the far left.
Here is another video from a few days ago "attempting" to get on the highway. It destroys the 315/60's in all three gears. Stupid nasty on the street!

the 5.3 itself can certainly take more then 14psi i ran about 20 on mine and it loved it
