Participated in a dyno shootout this past weekend. My primary reason for doing it was just to see where my numbers were. I came in 3rd. Couldn't compete with a 107 with a turbo or Stage IV 107. The rest of the competition was Stage 1 103's and down.
Other then the cams, I have a S&S power dual headpipe, Arlen Ness big sucker AC, and 4" RCX slip-ons and tuned with PV.
Don't really know what's up with that crazy line, the guy running the dyno said I either had a spark inductive issue (bad spark plug wires) or something out of whack in my tune. I couldn't find anything wrong or out of spec. It runs fine otherwise.

 

Possible clutch slip but I’ve never seen clutch slip with a signature like that. Are you running a stock clutch?
Pickup issues normally show up as voids or spikes.

 

Yes, stock clutch but a heavier spring.

 

I would think that there was an issue with the Dyno. Take a look where the torque curve intersects the hp curve... That's supposed to happen at 5225 rpm not 4800.... Software blip or maybe his ignition pickup.. Otherwise if your worried about it take it a good tuner...

 

The torque/ HP crossing point is due to the scaling being different on each side of the chart.

 

BAD clutch slip, and as jbarr1 noted the scaling is not correct. Very respectable peak numbers for a 96" with a cam swap

 

Thank you. I got the cams, push rods, PV, and map support from FM.
