afr up top? plug gap? plugs used...?

 

11.3 ramped to 11.7 and plug gap is .0032 but ill check for sure tomorrow. and they are one step colder.

 

Bummer. Was hoping to see good results

 

Dont worry as soon as I figure out whats causing it, ill be back on the dyno!

 

Gov what was the air density today?

 

1.253 kg/m^3

 

so it was just under 10 degrees C when you dyno'd?
what was the density last time?

and I guess need to know the humidtity. if it was humid, density goes to crap and the power drops. That said, air density isnt going to cause misfires, if thats what you had.

interested in what you find and results when you go back.
would you consider trying 2.9 and tune to it? wondering

 

It was right around 50 today here. Not super humid though. And yes I would be willing to try a 2.9. Guess I could do some research on pulley size one of these times I go.

 

At your expected power level 0.032 may be a hair wide; take it to 0.026 and work it up with some street pulls.

 

 

Japetr better get some Hoosier metric radials on that sucker for grip lol I think you are past Z2 levels, need more greeep.

 

I think I wet my pants
She screams when the spray hits

 

ORLY? Not that exciting.

 

In this boring state it is lol

 

what was the idc govener

you ever go back to the dyno

 

100% exactly at 7700

 

That dont seem right?

 

whats your base pressure nolan? I think alans right in thinking it was spark blowout, I run a .028"

 

43 base pressure, and ill try gapping tighter

 

damn I need to get this nitrous kit on the cobalt. wonder if the stock motor at 140k miles will like a 100 progressive shot on a 2.7 pullied m62 and e85

 

On a side note, When I arrived the dyno guy had to pull the aston martin vantage off I was like wow! thats a sweet car. He was like ehh its ok, its no cobalt ss though!

 

Don't know how to post pic?

 

is that when it breaks up

 

Nope it breaks up earlier. And Im going to try gapping the plugs smaller. And I wish I would have taken a pic of the vantage.

 

50shot really wakes these cars up.
Really nice jap
