Any ideas what kind of power it'll make??

Hey guys figured ask y'all what you think my set up could make?? My hand got split in half at work a few days ago so I'm just getting a little bored, so humor me

91 Camaro z28
Iron block forged 370
BTR Trinity intake
LSA cylinder heads, stainless valves, Trickflow spring kit
Comp cams 233*/235* .619"/.621" lift int/exh 116* LSA
Holley Dominator ECU
Holley 120# injectors
Icon 102mm TB
Dual 340 pumps -8an/-6an PTFE feed/return lines
Dual feed to front of rails
Racetronix regulator
94 chevron(no ethanol) pump gas mixed to 105
Built 4l80e with Jake's lvl3 rebuild and recalibration kit
Circle D 258mm pro series single disc converter
VS racing billet 80mm T6 turbo
Vs racing 50mm wastegate with dome pressure sensor
7# gate spring with 8# of dome pressure
Dual Mac solenoid boost control
A2A 3" intercooler
MWC fab 9" 3.25 rear gear
275/40-17 Mickey Thompson Street et drag radials

So I did get the bugs worked out before I headed out to work and have been hitting 15-16 psi. I was doing runs and logging things as I went along. I'm also at 13 degrees timing at WOT.

Just curious what it could potentially make as is, I can't really do much as I'm a bit of a gibble right meow.

Thanks everybody

You're probably over the 600 at the wheels mark. I am sure once it is fully tuned and broken in, you'll get a lot more.

Sounds like an alright start. Once I can get it on the rollers and tuned I'd like to see close to 900 whp

I wouldn't see how that is out of the question. It's a pretty heavy build.
