Default why am i only making 285whp???

im just wondering if this sounds right, here is my setup;
b16a1 forged base
turbonetics t3/t4
tail wastegate
turbonetics bov
front mount
vibrant connections
hondata s100 w/ boost option
eagle rods
arias pistons 9:1 compression
Arp head studs
Turbo precision injectors 680cc
block guard
bully stage 4 clutch
stage 2 driveshafts
GSR brakes
turbosmart boost controller 6lbs/14.5lbs shift on fly boost
285whp 200tq tuned at 14.5lbs

i just keep reading that people are running less boost on t3/t4 and putting down more power

You did not provide exact specs on your turbo.
You did not provide us with a dyno sheet to review.

well every car is different..it depends how healthy your motor is. i think that sounds about right, i know someone who did a ls non vtec at like 19 psi and only did 260 whp. maybe you have a leak somewhere. a little leak can cause you lost of power on turbo cars. Other then that,maybe try to boost more or go with a t4 turbo.

Maybe the dyno reads low. Take it to the track and let's see what the traps are, that's the best indicator. I've seen mega horsepower cars trap pitiful speeds and vice versa so I wouldn't be too concerned until you hit the strip.

well you can see in the picture that part of it is silver...so I think 285 sounds about right.

If it was something like a stock exhaust and S-trim t3/t04b with a stg1/.48ar housing, 285whp would be excellent for what you have. People who make a lot more power tend to have a full 3" exhaust, cams, stock ~10:1 pistons and a 60-1 compressor with a stg3/.63ar hotside.

You could also have a nasty boost leak you have no idea about. You could also be having blowby issues (blockguard or running too long richer than 10:1), a self-destrucing thrust bearing in the turbo, or many other issues.
