Don't give up on these TVS yet. Boost is 18psi (2.39, 10% lower), timing between 20-22. Lund tuned. BPS ported blower. Full exhaust.

Not really concerned. I've just made my engine as efficient as possible. It doesn't know its making nearly 1k crank HP. It knows it's getting good fuel, mild boost and mild timing and it makes what it's going to make. At 750-780rwhp, I made 18psi and 22 degrees timing through unported blower and stock manifolds, no ice box, etc. It was just as prone to go boom at that point. With your KB, it strains the engine a bit more. Taking away more HP to make HP than this smaller blower. Will it let go? Maybe. But it won't let go any more than any other 700-900hp GT500.
Oil is 5w-50 Amsoil with fordracing filter
Few 1/2 miles coming up I plan to attend. Car was built to go top speed so that's where I'll be racing
What about my setup is going to cause it to let go? Crazy high boost? Crazy high timing? Bad fuel? High rpm? Because it doesn't have any of those.
Your setup on pump gas is more dangerous that mine on E85. Plus, that 2 step/no lift shift will cause engine failure way before mine does.
That no lift shift saves me on more than you think. I don't use the 2 step feature, and I run a safe 91 tune. I daily drive it when I'm home from business. I'll be at 30k miles this year modded, and I'm only home 4 months a year!
People on E85 window blocks and destroy oil pump gears all the time. Hey, I hope it lasts you a life time. But I see it all the time...crazy numbers on stock internal posts, then no word for months. Their next thread: "Starting my engine rebuild". Ask Kevin Keener. E85 Lund tuned. On an "easy" test pass at Texas Mile shattered oil pump gears. 2 months later...engine rebuild thread. That's just one example. Pretty sure he was no where near what your pushing.
Unless you keep it under 6k and drive it 1000 miles a year, it will go quick at 1000hp on stock internals. Common knowledge around here. Just be careful, all i'm saying. It's easy to get into the "cheapest way to highest hp" club. But it quickly turns pricey...
