ashills said:sorry to keep reffering to evo but it was same sort of thing
we ran 1.4 bar and made 410bhp 320ftlb (aprox) at hubs
when we ran 1.8 bar we only upped teh bhp to 438 but torque was near the 400 mark this was because we were at the limits of the turbo but raising the boost bought the torque figures up
the reason u may have seen a bhp decrease is the heat u will generate by raising the boost also needs to be dealt with so if u have a nice big intercooler and waterr injection it helps to keeps things cooler
standard cams are 256 and 10.5 lift i think which are pretty good compared to alot of other stock cams
probably some one come on now and prove all that ive been saying wrong lol but its worked for me so far
standard cams are 248 duration and 10mm lift
