Anyone know off hand how to calculate the Dut. cy of the injectors from PW and Rpm of the motor??
Ok well If I take 11.32(my maximumrecorded pulse width) times 5500Rpms(max rpms) then devide it by 600...I get this (103.76)....Im over 100% DC??
Wow there 30lbs injectors... man i didnt think i would max them out so fast. Crap!!!!!
I attatched the file If anyone can check it out. It has the PW and such. Was about 10.5 or so on this 1/4 WOT run. But I have seen a max of 11.32 in other logs.
Looks like im dialing back the boost and being very careful till i get larger ones?? Crap:mad1:
you don't have the ADX setup to automatically output injector DC?
and yeah, lots of air means lots of fuel!
No it doesnt say the DC on the ADX I have
link me to, or post up, the ADX you're using, i'll add in injector DC.
easiest way to track the peaks during the log is to make a history table for it, or watch the monitors with it selected.
The Adx I use is attatched! Thank you so much :thumbsup:
there. added it in as a value you can with in the list view, and you can watch it via the history graphs as well, just setup for "maximum running" value, and plow through a log at high speed and the highest value will be displayed.
you can also put it into one of the monitors, but i didn't want to touch those myself.
Ok it was in the steady 80-90 Dc at a WOT log to 100MPH(max 91.22 Dc). Thanks man for the help!! I cant believe im making that much hp right now.....
Would being static cause a slight hicup in the PW?? It jumped to 120% DC for just a heart beat 2 times on that log. but no other values had that hicup...
witchhunter says ~320HP, using 30 lb/hr, at .5 BSFC and a DC of 90%. seems a bit optimistic to me.
of course, spark advance will have quite an effect on that.
I though BSFC was .65 or .60 on boost applications?? On my formula I used i came up with roughly 270Hp@90% and 250Hp@80%dc I really didnt think id hit those #'s with this build so quickly??
