Update on my Territory, ran a 13.3 last night on the quarter with me braking before the line cos was going to break out running DYO, so should have a 13.1 in it. Stock cooler was really battling so next step is a front mount, battery side intake & valvesprings to hopefully get down towards mid 12s.
Id definitely recommend going bigger than 40lb on injectors as not a massive price diff and allows for future mods.
Driveline wise, at about 300kwaw my ZF is starting to flare a bit (although it has done 180k) so I won’t feel too comfortable pushing it much more, no wheel spin of course being 4WD so launches are pretty hard. Il probably stick with early 300kws and hopefully consistent mid/high 12s to save having to drop big money on a built box. Apparently the input shafts are often first to go in the ZFs.
