My build is pushing 850hp and if I don't run at LEAST a 10.5 or better with it, I will be getting some money back.
I hear ya!
I was actually being a little facetious in my previous post. The point being calculators should be taken with a grain of salt. They're just approximations given the available data. I was correct in saying I was running 10.8's with 800 HP, using the calculator. MyHemi was also correct that 10.9 should be closer to 650 in reality. If I put just my weight and trap speed in, it gives me 817 HP. Probably close since we added timing after that pull. But it doesn't know that I'm actually running at 5860 ft altitude in 8200+ DA. Same with the Dynojet. It said 801 HP SAE. However, if I turn off the correction factor, I made 641 HP on that pull. And conversly, if I correct those 10.8's to sea level I'm running 9.9's. The more data, the more accuracy. That's why I log every run, and take a snapshot with my weather station on every pass.
I don't know what altitude Yar is running at, nor the DA, which is a combination of altitude and weather. Nor do I know his race weight. But it sounded like he was still tuning, so I assumed no slip, and was just going by the dyno readout. I do agree dyno numbers rarely translate to ETs. But they can be pretty close. As close as the trap vs weight calculation as my example shows. I'd imagine your 850 build will do much better than 10.5, but I don't know all the data about your vehicle and location either. But Texas is pretty low. I'm actually from Corpus. That's why I just play with the calculators, but trust the slips.
