Hello, this video is myself making a inlet plenum similar to the ford racing puma or lightening motorsport plenum, fitted to a 1.6 mk5 fiesta zetec s, it’s a plenum on a budget with trumpets and I’ve had no figures but from the driving experience of before and after it’s showing gains of power/torque increase certainly from 3000 rpm on pickup,
Since the video I’ve turned up my rev limiter too, I’m running the 1.25 gear box too and although I use all my gears 3rd is very long it’ll do 20mph-80mph (in Mexico 🇲🇽 of corse) no trouble no hesitation or bogging, 2nd gear is also very good.
I will be keeping a eye on my spark plugs and probably fit some uptated injectors.
Thanks for watching please like and subscribe, thanks Dave.
