Need opinions on dyno run?

[chimchim]

I got my car dyno'd today (Sorry I can't post graph). My peak numbers are 290 RWTQ at 4,000 RPM and 249 RWHP at 4,900. It was a dynojet model 248. Anyway, after studying my graph, I realize that the torque and horsepower intersect at 4,500RPM. I thought it should intersect at 5,252??? I was there the whole time and the car pulled strong all the way to 6,000 RPM's where it made 225 hp at the wheels. My A/F was 13.1 at 2,500 and trailed off to 11.5 at 6,000.

Can anyone tell me what happened? Does anyone have experiences with this occuring. My car feels strong. Is the dyno screwed up or what. Are my numbers FUBAR or do they seem realistic with my mods?

I tried to offer as much info as I could. Any comments or questions or answers are greatly appreciated.

On the Y-Axis(s), are Horsepower AND Torque represented by equal numbers?

 

[chimchim]

no. Torque ranges from 180 to 300 and hp from 50 to 275

 

[chimchim]

yeah yeah yeah

Thanks a lot Canuck. You just helped me without giving me the answer yet. at 5252 hp at tq are both at exactly 250 on their respective axis. You're the tits. (.)(.)

dyno numbers and a/f

Numbers actually seem high to me. Dynojet dyno. SAE RWHP and RWTQ. Temp = 40*F low barometer and low humidity. Maybe that helps.???
