Hi I own a mini cooper s r53 2005 model. Would like more information on Cylinder head and size of Intercooler. Awesome video and setup on mini!

[@rskdevelopments]

How much was gained from the head work. Im guessing at least 50bhp . These are the forgotten mods on engines these days. Well done 👍

[@am-mm2sl]

There is nothing ground breaking here. Just a "normal" mods for R53. They are all well known in Mini community. Big valve head, camshaft, 550 injectors, intercooler and 17-19% pulley.

[@Nick-vd7cg]

he kept the 11% pulley tho

[@wiwelwiwel9141]

LOL 283Bhp with a 11% reduction alone and no other means of adding oxygen.. Defying the laws of physics, amazing :)

[@wiwelwiwel9141]

so - "head work alone" apparently also includes a different cam, intercooler, throttle body, airfilter and exhaust..

Can’t run any higher % pulley with the 8k rpm limit because it’ll overspin the charger haha
