321hp ATW - Not as much as it should be?
Ok so first off my cars putting 321hp at the wheels / 240kw at the wheels.
Ive looked at other peoples mods and dyno sheets and it seems they are putting out more power then I am with less mods!
My mods:
Engine:
13B Stage 2 Street Port
Upgraded 2MM Apex Seals
Stainless Manifold
Twin 40MM Wastegate Runners
50MM Turbonetics WasteGate
Hybrid Garrett T04B/E
Stainless Down Pipe
3.5 Inch Exhaust
50MM Turbonetics BOV
Custom 100MM Thick Intercooler
Aloy Race Radiator
Twin Oil Coolers
400hp Walbro Fuel Pump
Driveline:
Light Flywheel
Front and Rear Strut Braces
18" DTM Bliz
Ksport Full Adjustables
Engine Management:
Apexi Power FC
My injector duty cycle is at like 98% which are standard injectors and boost is only at 10psi.
Another guy i no has basicly a standard engine but intercooler and aftermarket computer and is putting out 247kw at the wheels on 15psi.
Something just doesnt seem right to me?
Does this seem normal or should i be putting out more?

It depends on what the AFR is on the dyno.I havent got my single running yet but i have 1600cc secondary injectors.I know i was running over 80% injector duty cycle with my car running stock twins.
So knew when i did my single id have to upgrade injectors

Yeah ive been meaning to do the injectors but everything in New Zealand is so expensive to get.
Yeah 98% is quite high but its been like that for awhile and has never failed.
I think ill have to look at geting the secondary injectors sorted before i take it back for a tune. Im thinking im going to run the 850s as primarys then 1680 as secondarys. Should be plenty of fuel

Fuel system should be the very next thing you do. After that you are going to need to address the ignition system, upgrade your plugs, wires and install an HKS Twin Power. Once you start injecting lots of fuel you need to be able to keep it lit, otherwise it will just cause ignition break up.

What they said. You're maxed out on injectors, and only running 10 psi. The injectors won't give you more power, they'll allow you to run the higher boost your turbo is meant for. You'll probably come out at 345 at 12 psi, maybe 370 at 15, with the fuel to run it.

321 RWHP with a T04 turbo and @ 10 lbs is not unreasonable.
Also the only things in your mod list that matter as far as RWHP are:
Do you have a cat in there? I'm assuming you don't since you achieved 321 @ 10 psi. FYI mods serve for two purposes: One is to increase efficiency, and two is to be able to support higher CFM levels (changing out turbos, higher boost).
I don't think you are telling us his complete mod list. Are you saying his air box, precat, cat, and exhaust are all stock? Also no fuel pump nor injectors?
247kw = 331 rwhp. On stock twins with only mods being an ECU and IC is damn good. Now if he has a full ehaust then it's on the lowside as I would expect him to be at the 350 range.
Boost level and efficiency are everything when it comes to turbo charged cars. My GT35R is ok at 10 psi but it really comes to life at 12! It really is a night and day difference, that is why my low boost setting is set for 12 psi. ..
You really need to up the boost if you want the reap the benefits of your single conversion.

Yes you are correct.Everything in NZ is expensive.Ive just kept my 550cc injectors in my primary rail.
You say they have never failed,yet lol.

sorry guys, just had a look and he has pod filters and exhaust done and an aftermarket fuel pump but hes sitll running the stock injectors.
I would have thought I would be putting out more power then what he is.
Thanks for all your replies guys! it seems like maybe my setup is putting out a good amount of power on only 10psi.
Heres my Dyno sheet if anyone wants to look.
