Is this power correct

I just had been told 9psi at 285hp? Seems a bit low, so I figure this would be a good place to start out at.
I was just told at 9psi i should be making 350+...But i also wonder if this isnt different airflow with a much larger turbo eg; gt35r etc....

The gt2860rs is a t3...
Again this is a drift setup motor. Lots of tq and quick boost. Taking the motor past 8000rpm is asking for trouble.To much chance of spinning a rod bearing. The car came tuned from dcraft at 15psi at 350whp on 103 at 7700rpm..anything above 300hp in drifting is a waste mostly
Minus tanner foust with a nascar v8 800+hp in a scion

But I understand what you´re looking for, looks like a good drifting turbo.
Let me know if you decide to change turbo later on, I´ve used the Mitsubishi TD04´s for many years now and it´s by far the best 300hp turbo on the market. You can torture it for many years at high boost and it never fails, seen 250.000 mile TD04 turbos on Volvos run like new.
From 200-400hp depending on size and they all have internal WG and BOV, T3 flange.
Just wish they made bigger models, would love to use on on S2K.
You make good torque and depending on the size of your turbo you can move that torque band higher or lower on the RPM band. Considering you want instantaneousness response and low end power, this is the perfect setup. Just remember, HP is a result of rpm and torque, so if your turbo runs out of air up top, and torque drops off precipitously, of course your HP will drop too.

Realisticly a F22 makes about 200 to the wheels let's say (good round #). I know your and F24, so you could add in another 10whp let's say, but I'm ballparking here.
Add 9lbs of boost, is netting you another 85whp.
Thats about ~9.5whp per lb of boost.
Typical for such a small turbo.
Remember, not all turbo's are created equal, 9psi out of a gt28, vs a gt35r are NOT going to flow the same amount of air at a given psi.
You could also calculate into the fact that the dyno reads a little low, so who knows...in the end your butt will be the real test. Does it feel strong?
In the end, your in the +/- area, even if on the low side a bit, but that could be anything.
Don't sweat a number.

And i more then trust my tuner, though he has never tuned a f24 out of the few s2k's hes tuned. And I was told also that each 1psi equals about 10whp (give or take)
Thanks for the info guys, I just wanted to get some more feedback on this from the people ik had the answered
Vegas Drift 21 is this saturday....Cant wait to shut all these sr20's down
Your power numbers are spot on. The log manifold is whats holding you back. I bet VTEC engages around 6500rpm with that manifold. I have a log manifold on my f22 with a 57mm billet wheel AGP turbo. My car made 303hp and 245trq at 9.5 psi on a conservative tune. An equal length manifold or ramhorn setup like full race will flow so much better and allow you to set VTEC allot lower like around 4000rpm if you wanted. That alone would probably help you gain 50 to 60 whp. I recently purchased the ramhorn setup from Forged Performance with a 3" dp, and will be putting it on next week. Should gain around 80whp with the switch.
The only problem with these style of manifolds is fitment. I have width where as an s2k chassis has length. This originally came with a DC sport tubular manifold and thats when it made 350hp on 15psi.
I didnt want to take the power above 300 due to possible ring land failure. The Vtec is set around 5500. I might talk to my tuner about lowering it another 1x or so. I know ideally my setup is a complete bust for an s2k motor. I would love to throw a ramhorn style manifold, bigger turbo and crank the boost up lol....

Your tiny turbo and log mani definitely isnt helping you make good power.
Your setup is similar to a greddy kit so at 9psi its about right. Your tq is higher then usual cause of your 2.4L

This is about what I would expect.
I would think lowering your Vtec crossover running a log mani like you are would hinder you more than help. From what i understand you actually need to raise your vtec crossover with a log mani to allow power to be made. Dont hold me to it but that is how I have understood these setups.
