I have 620 rolling around in my head, but we'll see. I can't help but just laugh out loud at Lykin's comment about an "averagely generous" dyno. Typical. If your piece is good, then, of course, my dyno is wrong. For any who care, I went to great length to verify my equipment. While all dynos are different, I took a 715 hp street engine up to Bischoff's and spent a day on it. We unhooked it and drove straight home and put it on mine. The DePac system I have has provision to create formulas to make adjustments separate from normal weather correction, which I also have. We tuned my data to match the results from Tony's Superflow, and it is within 2-3 hp of his dyno throughout the range. We tuned for Engine Masters on Tony's dyno, and we didn't see a significant difference between his and the JE Pistons facility used for EMC. Many folks thought that dyno gave low numbers. I have run many engines at BES. I know their dyno is as "right" as they get, so I adjusted to match it.
There are many, many factors that can contribute to differences between facilities. Numbers are just numbers. The machine is a tool, but I did need to get an accurate baseline to compare new stuff to my old data. Proof for the customer is in the seat of the pants, and the ET slip.
I don't come on here very much anymore, because as soon as the opportunity arises, there are comments such as the "averagely generous" to take a shot at our results before we even fire the engine. It sure is easy to belittle someone's effort by always dropping hints that the data is wrong.
We did our best to build Joe a good piece with a few changes, and most of the parts he already had. I hope we did good for him. We'll know tomorrow if the creek don't rise!
