![]() So maybe they sand bagged the first dyno pull, then floored it on the second pull with the only change being the addition of the velocity stack!Īlso, strange how the HP and torque figures were exactly the same after 5300 RPM when the engine on the first pull finally went open loop. It looks like the number is bigger on the second pull where they actually floored it at a lower RPM. The little peak at the very beginning of each pull is where that measurement was made from. Yes that dyno sheet shows numbers of 22 Ft/Lbs but that is because the vehicle under test was an automatic and it was the flashing of the torque converter. Then you see a claim of 22 ft/lbs of torque. Plus, look at the erratic horsepower and torque curve. An 8-stack engine isn’t complicated it’s just a little different than a four-barrel engine.
