Hp estimates I have a 6.0L (LQ9) wanna know what you guys think about the setup and what hp/tq it would crank out. Also anybody with a similar setup please share numbers. Much appreciated (stock 345hp 380tq) specs: 236/246 cam tbss/nbss intake 92mm throttle body 799 heads spring upgrade 1³/⁴ longtubes 42lb injectors looking forward to hear what you guys think |
Sure, I'll take a guess. I say 420/395 to the wheels. Wait, which transmission you running? |
4l80e 4000 yank stall numbers sounds good to me |
Oh, the 4L80. In that case, my new guesstimate is 395/375 to the wheels. |
Do you have 799 heads, or just the springs? As you can see in my signature, I have 6.0 heads (317 castings). I had mine milled down .030" to get the compression up. You wouldn't need to do that with 799 heads. You have a bigger block, cam, and throttle body than me. Based on that, you should be able to get more hp/tq than me. If you don't do something with the heads, you will probably end up with close to the same hp/tq as me. Don't ignore the heads. You can easily make more hp there with what you have. They just need a little tough love. ;) |
I have the 799 head I just have pac springs in them no mill work and how much you put out |
Those heads should work well. It wouldn't hurt to shave a couple cc off them, but you should still be around 11.04:1 compression. I'm getting 382hp/368tq at the wheels with a 10.4:1 compression. My heads were also ported, but I still have the stock throttle body. I'm gonna stick to my second guess of 395hp/375tq. |
