Can anyone tell me the stock 1G A/F ratio under WOT/BOOST? I believe I was told a figure quite low and want to confirm it ad pass it on. Please also send the info to marksweet@webtv.net. Thanks so much. I am a former Conquet owner and the A/F ratio is a question I want to answer for these DSM's! Mark

About 9.5:1 if all the factory calibrations are intact.

I hear you can go to about 11.5-11.0:1 if you have good intercooling?

isnt 12.5:1 for best power?

The AFR you want to run at, and the AFR that is optimal for your particular setup, has so many factors it gives me a headache.

With good intercooling, and a properly efficient setup, 11.5:1 to 12:1 would not be a problem at all. On race fuel, 12.5:1 is usually not a problem, and people often go leaner than that by accident.

It depends on a ton of things, intercooling, boost level, and turbo being three of the most important.
