Alky 23lbs boost plug reading?

[cgamino]

What should the spark plugs look like with alky. Knob on 5, Running 23lbs, 10.5 to 1. 22 deg. timing. Mine seam a little on the light side? Thanks

The only way to read plugs is install brand new ones.. make a pass and shut it down.. pull plugs and read them.

If your driving/idling/cruising.. you cannot tell whats up with the plugs. Except some major issue.

If you pull them and they are tan colored.. leave the car alone

I'd just get the AEM wideband for $200 and really find out what's happening, it's cheap insurance as reading plugs is way too late if it's lean and knocking.

With 10.5:1 compression and all that boost and timing, I'd be surprised pump and alky can handle that cylinder pressure, especially with the knob on 5.

....With 10.5:1 compression and all that boost and timing,....

I would guess that he was talking about the air fuel ratio when he says 10.5:1. If he's running Fast XFI, he probably has a WB sensor.

Yep, you cannot get a good plug reading from making a pass at a track,then idle back to the pits & pull the plugs to read them.

You would need to install new plugs,make a pass,imediatly shut the engine off, & pull the plugs to read them.
