What size injectors are you running?

Those with a 70 turbo and deep into the 10's, what's your injector of choice. Looking to move up from my 75's. Thanks, Brian

85s on one car, 83s on the other.

Russ, could you tell me the %of duty cycle at WOT? Which do you prefer---Delphi or Seimens? Thanks, Brian

 

[Russ Merritt]

No I can't. I can tell you I'm not using all of the injector as I have plenty more adjustment left in my R chip. Only on TW 7 with 8 clicks more of adjustment if I need more. That was the car with the Delphi 85s, 10.34 @ 132, 27# boost, 70Q.

I learned how rich it was on the dyno with a wide band 02. I was on TW 9 and was in the 10s A/F ratio.....

83's.....duty cycle in the low 80's at 130

Russ, that's good to know. I am also running ME-R w/ a CPT70Q BB. Thanks also for your input Woody. I'll feel much better w/ low 80's. Brian

I run the 96's duty cycle is 67-70%. I like a little extra cushion.

Phil, What are you using for fuel management ( FAST, ME-R, ect.)? How are the idle and low end characterixtics? Thanks, Brian
