Dyno Results... a little too low?

[TTnotch]

The car has a Steeda CAI, 2.65 pulley, Pedator Tune, n off-road x-pipe.

 

The car dyno'd 527whp and 526rwtq. I was expecting atleast to be close to 560 or so. I'm pulling 12.0 a/f ratio all the way across. I'll try to get the dyno sheet up in a bit.

Hey there,

 

Not sure what the exact numbers are, but I have heard that you loose anywhere from 12-15% through the drivetrain. IF those numbers are somewhat accurate, and your car is putting down say 600 at the crank, that would mean about 528 at the wheels - assuming 12% loss through the drive train.

 

I will ask our dyno tech here later on this morning and see what his experiance shows.

 

Hope that helps some

those are good numbers for what you have. Depending on the day your HP could go up 20 hp.

And the amount of driving you did prior etc. I did a dyno with a pretty cool engine at Evo and put doen 685 rwhp and did one here on a dynojet after a 2-2.5 hour drive on the highway playing around and only put down 630 - 640 rwhp. The mustang Dynp at evo is approx 5% lower than a dynojet so you can see the difference in the conditions, engine temp etc there.

 

The dyne is a tool - I wouldn't worry too much about 20-30 HP on your peak number unless that's what you are really trying for. I'd rather see the results at the track and I am confident the car is putting down good power with my recent 134.56 trap speed. This is on a KB Stage 2 (No TB) and running ET Streets. No nitrous on the car yet.
