Cylinder Head Porting and Power Production

I guess I’m not getting my point across that there’s a fairly good possibility your dyno sheet is not an accurate presentation of what those parts can make for power.

I wouldn’t, and dont, put much faith in dyno data that doesn’t really make sense.
Like I said earlier, I’d have less of a problem with taking the power numbers at face value if the fuel flow and bsfc numbers corresponded to the power output....... but they don’t....... and by a pretty wide margin imo.

I guess what I’m saying is, if I had it on the dyno here, with a known good carb on it...... I’d be shocked if the power and the bsfc, and the fuel flow all agreed with your sheet.

Unless(there’s always a caveat)........ there is something actually “wrong” with the motor.
Not the combo, but something actually malfunctioning or failing.

I am very much in agreement with Dwayne on this--That engine is very weak for the sum of its parts or like Dwayne said the dyno room is crap (eating its own exhaust) or the engine is eating itself. Should be WAY stronger than that. J.Rob
