Pull my dyno - Automobile puts the IS-F on the rollers
In no time, they headed over to their local Dynojet. The result? Well, they're a little disappointed, and they're calling the torque delivery peaky. Looking at the dyno graph, we're not sure we'd agree entirely with that assessment. There's at least 225 lb-feet at the wheels from 1,800 rpm, topping out at 318 lb-ft. First, let's point out that 15 percent torque loss through a drivetrain including an eight speed automatic is pretty phenomenal. Secondly, the torque curve is pretty fat below the peak. What is surprising to everyone, though, is the way the power drops off precipitously on the other side of the 5,200 rpm peak. You'd think an engine with 4-cams and Yamaha-designed cylinder heads would be a revver. Of course, there are lies, damn lies, and statistics and these dyno results are sure to kick up some debate. What still remains to be seen is how the entire package works when pitted against its bogeyed competition. For that, we must still wait.
