So my Mk 8 Ford Fiesta ST was kinda quick, but anything quick left it standing on acceleration, took till 3rd gear to get really moving (Ford detuned 1st and 2nd gear to deal with power/torque issues).

Anyway, been slowly modifying, put in a Mountune high flow throttle body, then a foam dreamscience filter with stage 1 Dreamscience tune, extended air intakes with intake trumpets for more air, and just recently added a bigger intake tube from airbox to throttle body that only increases airflow over OEM by 10%. Also put in a Collins performance engine stabiliser bush to control the power and torque down and reduce wheel hop.

For some reason the last mods of bigger intake tube from airbox to throttle body, and Collins engine stabiliser bush has resulted in that sum of all parts greater than linear benefits of each part added up.

Realisation dawned on me when last couple of days out pulling a new Hyundai I30N and then putting a Commodore VF V8 SS in it's place from lights (and boy he was really not happy) - it has dawned on me that the little ST is now actually a rather pacey little machine in terms of acceleration off the bat.

And I have received new Mountune charge pipe kit that flows 62% more than OEM, to yet be installed, which I suspect will make the biggest difference to date of all hardware mods.

Felt good to suddenly see results in performance from relatively benign better breathing mods.

Added bonus got a rear shock absorber that was leaking replaced under Ford Warranty with 1.5 months warranty to go....Growing old disgracefully....and loving it.
