I believe the svt has 3x lb flue injectors. I would call ford dealership and ask the parts departent. Below is the a/f ratio with rpm of a focus svt dyno. look at how rich it gets at the higher rpm's. Does the a/f needs to be 11.5? I think that is too rich.
rpm a/f ratio
2485 14.7
3065 14.2
3894 13.3
4640 12.7
5220 12.2
5468 12.1
6048 11.8
6214 11.6
6379 11.5
6628 11.4
6794 11.5
<font size="2" face="Verdana, Arial">HOLLY ****, just by tuning the a/f on a SVT focus you should gain like 10-15whp....
damn thats WAYWAYWAYWAYWAY too rich....
This is a first, thats huge news guys, strap on a apex fuel controller, lean it out and watch, i bet you can hit 160whp without even any mods...
Tom, i dont think i will ever use all of the 24lb injectors if i got the, i dont think i can go too much over 170whp without going crazy with this NA thing, RPM, rough idle, huge headers, cams....compression
I would like to hit 170whp and still have nice low end, good idle, 7000rpm redline and my 10.5:1 compression
Because later, i still plan to go boosted ya know? Im gonna go step by step, im gonna build the bottom end to do both, work well with my NA setup now and beat up on it, and be also setup for some boost, no more than 15psi though...
so the project goes on...
