I`ve 4 x 850cc injectors, Denso (Supra TT pump) static 40 psi, B9EV leading - B10 EV trailing (gap .022) running 16/17 psi @ 10.8 stoich (9000 rpm) and made 402 RWHP for 4 years now

So you should be fine!

Its an Auto, so if you`re manual you could probably get more power out of it.

 

429@15psi with stock fuel pressure!! Just get a denso pump and a rewired job. If a FPR @ 40psi i think i could managed 450whp. All this with 850ccX4. yes it can be done

 

here's how i see it:

a GT35r makes 56 pounds per minute tops at one bar.

at 11.3 AFR that would be 4.955 pounds per minute of gasoline.

that's .7742 of a gallon or 2931 CC/Min.

4 X 850 = 3400

so you should be at 86% duty cycle.

hpwise: 56 pounds per minute times 14.471 = 810 CFM/1.92 = 422 max rotary rwhp target.

I've made 450hp at 15psi with a good SP motor and GT35R. But on average you should be in the 400~425hp range with 15psi. 4 -- 850's should be enough but probably just barely...
I would raise the Fuel Pressure to somewhere around 50~60psi.

 

Why risk it..... couple hundred for the right injectors, or $3k for a rebuild?

Rotaries don't like lean......period. If you want your car to be reliable than build it reliably....

 

Well that is true, but he should know when the injectors are close to being maxed out. Most all standalones report duty cycles. And generally as a rule you work your way up in boost levels and power so provided he pays attention to his injectors he'll be fine.

 

My turbonetics T-62 spooled up at the same time as the secondary Turbo does with 850x4 set at a 80% duty cycle no port, with a wallbro 255. It wanted to go past 15psi the piece of crap stock pressure sensor wouldn't allow it.Smh... 19psi my ***. Well while was on my way to install my 3bar, I crashed. But yeah the stock sensor was cutting me at around 4k-4.5k. But now, I'm going fora smaller hot side gt35 by cx racing. Same injectors and aeromotive 340. But I don't want more than 17 pounds though.
