GS-F Conversion...is it worthy to be called a F?

The last white car dyno was with the old engine made 585whp at 22psi on e85, and 710whp at 34psi on e85. The 1khp is going to be with the new engine and transmission running on C16 @ 40psi-ish range.
I just snagged the seats a few days ago. I'm waiting for them to be shipped here. Once they're in, I'll have it hooked up and fabricate custom brackets to make it fit.

All I've seen are claims with no proof, ever.. not only that, but it was said on video that it made 585whp, and no dyno sheet was ever posted. Also, the dyno was reading low 
Give me some time with a video included. I'll swing it by my friends dyno again soon. It makes 550whp at 20psi with methanol injection on a motor with 9.5:1 compression. On 100 octane unleaded @ 25psi, it made over 600 but I was maxing out the 340LPH fuel pump and it was starting to lean out up top.

340LPH is enough to flow 1000cc injectors at 100% duty cycle...that's enough fuel for 800whp+ through an auto trans....considering I'm making 360whp at 85% fuel duty on stock 440cc @ 12psi on a T78, with 5-7 degrees out.....get this..ON 91 OCTANE....yeah i'm going to call BS about running out of fuel. These numbers just don't make any sense.
Please post dyno sheets
Cool GS-F by the way, you must have searched for a while to find those front seats, I wish i could find a pair.

And second, how the hell can 340lph Deatchwerks pump run 1000cc at 100% duty cycle? So that would mean a single Walbro 255lph according to your reasoning run 750cc injectors at 100% duty cycle. According to your same reasoning, the single Walbro on 750cc should have zero problem supporting over 700hp. And the single 340lph DW pump should be able to support near 1000hp on 1000cc injectors.
The OEM Denso Supra pump outflows the Walbro 255lph, so why on earth do supra owners upgrade their OE fuel pumps when surpassing 550-600whp?
The single Walbro runs out of fuel at around 500hp. The DW 340lph pump give you a little more leeway and will allow around 600hp. I'm running this power through an automatic, so there's more power loss compared to a manual.
I'm also too cheap to pay for the dyno just to see how much HP it makes. Anyone want to spot me $50?

This makes no sense, unless you're tuning your car extremely rich.

Yes, stock ECU to control VVTi. It actually does a pretty good job. For the MAF, it's running as a blow through with the BOV located before the MAF. Never put your BOV after the MAF as this will will cause a engine stall condition whenever you "blow off".
As for how well the car runs. I will be posting some new videos when I have time. It runs very smooth and the power is very strong. Like I said before, all of the magic is in the tune. I've nearly mastered tuning the Lexus ecu for these cars and I can get the tune down damn near like OEM. No check engine lights, and zero codes...just like a stock turbo car should be.

Are you gonna be making a plug and play harness adapter for the fic?
Will it work for the SC300 too?
Thanks for your time Jeff!

I would love to see a 340lph fuel pump flow enough fuel for 1,000 hp. Im going to call dumbass of the year award. Get ur facts straight before you start trying to call BS on someone. If you knew anything about the 2jz you would know the numbers Jeff is saying the car is making is very doable.
