Went to the dyno tonight, not really sure what to think.

Here's the numbers. Temp around 80 degrees. Humidity around 50%
max HP: 296.48
max TQ: 304.29

SAE Corrected
max HP: 484.87
max TQ: 496.54

The motor was heat soaked from the very start. I will try and get the sheets up ASAP. I dont really know what to think. I was kinda thinking this was a little on the low side with the mods I have. What exactly does SAE corrected mean and does it really have any significants? The operator said my A/F was even at 13 all the way across. If you guys could give me your full input I would appreciate it. I got a vid also that I will get put up soon. Thanks. Dustin.

I'm going to go out on a limb and say your corrected numbers are a little off. SAE corrected is normalizing the numbers so that they can be compared to all other numbers regardless of conditions.

I was kinda wondering about that. Thought that seems kinda un-realistic, wasnt really sure what to think tho.

Here is a link to one of the graphs. I know it isnt good at all but I had to take a picture of the graph with my camera. But it might give you some sort of idea what its doing. I will try and scan the graph as soon as I get a chance. Thanks.

There is no possible way. Go to a different dyno.

I understand that the corrected numbers are way out of wack. But by looking at the lines on my graph, do I have some major issues that need fixed?? I looked at a few other graphs of other members cars and there graphs are nice and smooth. Mine are all over the friggin place.

What was the barometric pressure? I can't get to the graph from your link. Also was the converter locked or unlocked?

I agree with the above. Ignore the SAE numbers.

You have to log in to myspace to view the pic and I really don't feel like going on myspace at the moment.

Sorry about the Myspace thing. Its the only place for me to post the pic right now. My dyno sheet says the pressure was 19.36 in-Hg. If thats what that means.

Weather.com says the pressure right now is 30.36, but I dyno'd about 2 hours ago.

Short answer, YES. That graph is not smooth at all. There's definitely something wrong. Check your fuel first, then maybe ignition.

X2 , there is no way it should be anywhere near that wavy.
