This is graph depicts a run with 1 NX 100shot, wet, single nozzle style.
Car has LT's, lid, Corsa can, hotcam.
What do you think?
Is theA/F ratio appropriate? Do I have to worry about that slight lean spike upon initial hit?
Thanks for your help.

 

bump!

 

Well, imo, it's a little much. what it's doing is giving you a nice torque spike, but at a cost. Going that lean to get this false torque is not a good thing to do (you can tell cause it goes right away once a/f comes back to a safe ratio). You may or may not get away with it for some time. Looks like time for a pump, and if that doesn't cure it then a return and reg at the rails. Your draining your fuel rail and fuel system can't keep up. Now, some may say don't worry, but hey, it's your call in the end.

Well, I have an intank Walbro 255.
So you think the restriction lies within the fuel rails and a simple upgrade would suffice?
It seems odd, as none of the other "sprayers" I know end up with dynographs looking like mine...

 

Every car is different. A lot of guys just live with it. Myself, I went with the return and reg at the rails and have no lean spike what so ever. Some others will chime in for more insight.
