And there you could all agree on whether to modify them or not...

I'd go for a 17% pulley, GRS intercooler, Janspeed manifold + cat and some NGK plugs.

19% is horrendous for heat and TBH even the 17% is a bit hot around 6k-7k rpm.

Because the GP has a lot of work, you would probably see some decent gains from switching the 11% JCW pulley for an Alta 15% pulley.

Do remember though that any pulley smaller than 11% will spin the supercharger past the maximum limit Eaton say the supercharger should do.

Because it is a GP I have hard time modding GP, so far just ITG filter, Hawk HPS Plus pads, HSport rear swaybar, JCW strut bar, and RMW tune. If I were to mod out the GP it would be the JCM 225 or 235hp kit, just to keep it real to its John Cooper heritage or roots if that makes sense. And then if the the mod bug was still present I'd buy an extra head and cams from RMW for insane wheel horsepower.
