Going off this (
http://mrinjectoruk.auctivacommerce....7-P598732.aspx) the vtr injectors are 154cc@3Bar (not sure if these are the 90bhp or 98bhp ones) , therefore:
Change the cc to a 3.5Bar FP:
154 x (3.5 / 3.0)^0.5 = 166cc
Boost
166cc = (Max BHP x 5.6) / 4
which gives Max bhp = 118hp
BUT ideally at that BHP, you'd have 147cc injectors at 80%duty cycle
NA
166cc = (Max BHP x 4.6) / 4
which gives max bhp = 144bhp
BUT ideally at that BHP, you'd have 147cc injectors at 80%duty cycle
