Sorry if this is a redundant topic but I switched to Q16 about 2 months ago and jetted up according to what was recomended by VP. Went from 97 jets to 98 and 2 sizes on the air bleeds. My O2 meter said I was about 13:1 air fuel.
My engine is a 614 with big duke heads and a single 1440cfm blp carborator. This is in a 1800 lb dragster that we are running in top dragster in the Pacific Northwest.
Last race we were at I switched over to a set of merge collectors from the standard collectors with a 5" outlet on them, I was told that was way to big. Now the problem I am having is that my a/f meter is reading around 15:1. I jetted up to 99 and it didnt change anything. I called blp and they said that I need to go up to jets with a .140 oriface in them which is much larger that the .125 in the 99 jets.
I just wantd to get everybodys opinion on this big change and see if it makes since that the collectors scavange that much better that I now need a ton more fuel or is there something else going on? Has anybody else needed this much jet with Q16?
Thanks for your help
