afr's and boost prob
 
what afr's do you guys suggest for me to run on my turbo r/t? the guys on srtforums say somewere in the 11.4-11.8:1 range.

and to anybody who has used an agp wastegate on a srt turbo... how the hell do i get it to go less than 11pounds? i only have the arm screwd one thread on and its at 11 pounds in a 2nd gear pull. i want it down to 8 pounds.... should i try moving the boost source for it so maybe it actuates quicker?

with my AGP wastegate i could get it down to 2 pounds of boost or up to up to 20+...
where does the vaccum line for the wastegate start at?

i have it coming off the nipple on the turbo housing that is on the flat section... im thinking i should move it to the turbine outlet nipple. and 11 pounds of boost and the drag radials i have on it worked unbelievably

i ran the wastegate and blow off valve off of the brake booster vaccum hose...it works better then the compressor housing

yea.. ill try that next.. i got it to 9.5 pounds of boost tonite.. .but im outa fuel pressure till i get the inline pump in.. shoulda been here by now. with the stage 0 srt stock injectors its at 13.0 afr at 10 pounds of boost.. .still to to lean for good. at idle its at like 9 pounds of fuel pressure and goes from mid 12's to to 14's air fuel... is this normal?

i never had an air fuel gauge in my car so i wouldnt even begin to try and figure that one out for ya

lol... yea everything's pretty much set now except boost lvl and fuel ratio at boost which is due to the stock fuel regulator. im getting pissed now that my inline pump hasn't come in a week late now.

any guesses what i could run in the 1/4 with the drag radials and 10 pounds of boost propperly tuned?
