Hi,
For the pullied Terminators, do you guys know your injector and fuel pump duty cycles?

What pulley and DC are you running?

For the stock pulley, I was at
FPDC = 86
Inj DC = 81

For a 3.1 pulley, I was at
FPDC = 90
Inj DC = 91

For a 2.76 pulley, I was at
FPDC = 92
Inj DC = 100 (had an old fuel filter here so this could be wrong)

I'm gonna try a 2.93 pulley I have sitting here and see how that looks. These were all at 6500-6600. I'm gonna try to spin it lower since I don't need to spin it that high.

Mine at WOT on a 2.7 is at .47; I’d have to check IDC if my X4 has that config file. My car runs 11.4-11.7 A/F ratio that sweeps starting 11.4 at 2,500 and 11.7 at 6,500. However my MAF counts are almost 1k that was my limiting factor. I make 475/515 no BAP and stock MAF and injectors.

you're probably looking at fuel pump duty cycle.....you need to look at rtls pump duty cycle. it's pretty much double the .47, so your pumps are at .94

I Should have said that as yes it’s not rtls duty cycle. That’s when it’s hot out, normal WOT is around .38 to .44 when temps are below 80 outside.

I'm guessing alternator and not the battery....our cars SUCK for alternators going bad.

Alternator, you are correct. The battery is fine. My other Mystichrome was like that too at WOT so I’m just accepting it as a Terminator thing. At idle, it’s still over 14 so I guess that’s how they are

I believe it’s all the rpm. From what I read on the Shelby’s they didn’t put them on the same drive as the blower.
