Mine was genuine dyno'd (several times different rollers) always made over 195 constistanly but that needed a lot of work.
Mine had, 195 chip, 701 injectors, hybrid t2 turbo, pace intercooler and rad, 285t2 piper cam modified airbox samco hoses, upgraded breather.
Koni suspension. Scorpion 3" and Bailey piston dump valve(essential back the in 🤣) would hold 19psi.
Was a proper missile back in the day! everyone knew the car it was so quick weighed about 950kg I reckon.
Chap I bought it of swopped it for cossie he said it was s**t slow compared to the fiesta.
He ended up going over 330bhp in it to make it feel quick.
I lost count of how many Escort RS turbos etc I used to make look stupid they would say they were running a supposed "200-250🙄" plus power with just a stage 1 chip or bleed valve they were actually about 160 if they were lucky🤣
