I will have to disagree with you on the dyno. The dyno is a very valuable tool to use with a new engine. It not only helps to break the engine in and make sure there is no mistakes, but it is also very useful to tune the engine to get maximum hp & torque out of it. This information is useful in helping you set your car up. The torque convertor is what can make or kill ET. If you can provide a torque convertor company with copies of your dyno sheets weight of car type of trans rear gear & tire size, just about all of the good companies can build you a good convertor. Your dyno sheets can also help you select the optimum rear gear ratio. Also, if you know the hp & weight of your car you can get a good idea of what the car is supposed ET, if it does not do that you know you are losing available hp somewhere. I know there are gonna be dishonest engine builders who will calibrate their dynos to show 100-150 hp more, but the torque of the engine is what calculates your hp that is why I included the graph. You can compare the torque to the hp and do the math on them and that will tell you if the hp is correct or not.
I guess back in the dinosaur days of dyno there may have been a big variable between one dyno to the other. But now days with the modern dynos if the operators keep them calibrated you find very little hp difference from one to the other & that very little difference will be from the load percentage they set the dyno up to put on the engine. The man that dynoed my engine used to work with Gene Fulton. He just bought a brand new state-of-the-art dyno this year. The people from Stuska Dynamometers had just come back & made sure the calibrations were correct after 100 dyno pulls when he started on mine it had 110 pulls & when he finished, it had 120 pulls. He does all his dyno pulls with an 18% load on the engine, this is more or less the standard that most all engine builders use. This is the percentage load Gene Fulton, Sonny Leonard, Shafiroff, Reher-Morrison all dyno their engines at. The recommended dyno load is 10-20%. That is why I chose the very best person with the very best dyno equipment to dyno the engine, I wanted exact numbers.
You asked about my car, it is a rear engine dragster. It should weigh around 1800 pounds with the BBC engine & myself included. It has an ATI MRT Treemaster Convertor, ATI Glide with 4:29 rear gears, Goodyear 34.5x17-16 rear tires. In the picture I will post for you it had a 572 cu in all aluminum Indy Mopar engine. The dyno sheet from Indy said 958 hp @7200 rpm with 1-4 barrel on gas. I put a Tunnelram with 2 Terminators on alcohol on it, that should have given the engine another 75-80 hp. It run 4.64-4.68 in the eighth mile.
