it's defo. the series 4 that had the split pulse jobbie.

actually, TMK the S5 had the bigger A/R. I've looked at quite a few and the S4's are 0.88 (equivalent*) and the S5 1.00 - it is def. the one with the tricky dicky twin flap wastegate arrangement however. the S4 has a piss tiny flap that is very prone to creep. back end of the S5 they can be high flowed easily with T04 wheels and comp covers. my mate ran a flat 12 in his 4.0l cortina, had; Garrett H3 60mm compressor wheel TO4 .6 comp cover 360 degree thrust bearing Sierra GroupA turbine full boost by 2000rpm - but on 4.0l - ie: not so good on a 2.ol C+ *they were twin scroll (rubbish) with a 0.4 primary and 1.0 secondary

high 12's low 13's @ around 110 - why do you care so much that you need "absolute" proof?

and the engine builder? sorry to be busting your ass

who rebuilt the engine? what gearbox, diff etc?

why does everyone have to bust each others balls over stuff like this? it's not a dick pulling contest.

the engine in the car now - is it at that spec or something else? what is different from when it ran the 12.9?

nice ride got anymore shots? interior perhaps? who rebuilt the motor? tune details? Cheers, C+
