Guys,

Thanks a million for the feedback, this is exactly what i was looking for...Really appreciate it...

By doing as you suggest, '1mm c port jet and a 3.2mm r port jet'... What boost should I be expecting to see as a peak boost figure and then as a held boost...

I'm completely new to Turbo's, so just learning my way...My car was previously a 1.6 Xflow before i swopped in a 24V Cosworth BOA before the latest Cossie YB Swop....

Some pics of the outside, will stick a few of the engine bay as well



Some pics of me just having some fun in it....



First Day with YB running approx 240BHP while i getting to grips with Turbo Power..
