I'm not as sharp on this as some of these motor heads are but I noticed several things that stand out from normal dyno sheets.
The graph starts at 3,000 rpm.....that seems odd and maybe one of these guys can answer that. Most start down around 2,000-2,200 rpm.
It's smoothed at 4 instead of 5......why and what affect does that have on the true picture? Most dynos are smoothed at 5
It's in STD instead of SAE.....again, why and what effect does that have on the true picture? Most dynoes are in SAE
Just to many variances to compare your dyno sheet to everybody else and why did he do it this way. I can't help but wonder if he did it just to make it look better to the casual observer.
