thought i'de add a note to this.

if you buy a stage then later decide to raise the boost, the cost of a smaller charger pulley to up the boost is quite reasonable. i have just went from a 22 tooth pulley to a 21 tooth pulley, giving a raise of 0.15bar boost (2.17PSI). its not here yet but if anyone decides to up the boost, just send them an email.

Thanks for the advice Inzor. What difference will that potentially make to your power output? Does it require any other mod to do that?

no other mods needed, i'll have to do some sums to work out the potential gains.

the smaller pulley should give me somewhere between 10 and 30 extra bhp if my sums are right. depends how much pressure the charge cooler is costing me at the manifold.
