anyone know what boost a WR Sport RB5 makes? Would also like to know about anyone who knows what their car was before and after adding the kit.

Cheers

 

Iain,

You want an STi mate.......

 

Iain,

If I remember rightly a standard MY99 car should peak at about 11Psi and hold 10 (?) so a standard RB5 will be the same.

PPP'd MY99 cars should peak at 14 and hold about 12psi so a WR Sport RB5 should be the same.

James, you cheeky muddy-funster! You know how I love my car! STi would be nice but the RB5 does it for me. I'll take handling over performance for now. My un-PPP'd car peaks at 17/18 psi and holds 16..........why is that!!!!???? I blame Lee C.
