Guys, check out my dyno graph now. Clean up to 6400 then dips and comes back up. Is this valve float or something else?

Thanks for the help.

 

I don't think it's valve float.

Almost looks like a little bubble in the fuel supply.

 

How would you get a bubble in the fuel supply?

 

Looks like they lifted.

For the rest of you the duration a .050" is 243/251.

Did they lift because they heard something???

 

I don't think so. That's just where whatever happened, happened. Then the power starts in again, but isn't as smooth. I think it's pretty much peaked, but looks like it would carry it out to 6800-6900. I just don't know what this is. He said you could definately feel it.

 

did you video the run?

may be a mis or ignition issue...... I have seen similar dips when a dist is starting to go out.

 

I wasn't even there. He's been working on the car for a while. Had a lot of other issues (opti, fuel pump)

 

Any chance there is a problem with the MSD equipment or Delteq causing a rev limiter to kick in?

Get that stuff out of there and start from basics. People cause themselves a lot of hassle by overcomplicating things.

Heck if you have a stock opti put it on and try again.

 

I assume you were looking at my car domain page. Go to page 7 for updated setup. The Digital 6 box is not hooked up at this time though for that very reason, no extra variables. I would hope there's nothing wrong with the opti, since this is the second one with in 600 miles, and no the dowel pin is not to deep, right at spec .030 in to opti. No delteq, just the basics on this run. I thought valvetrain.

 

Pump cavitation?

I'm just guessing here...
