what hp are u making on stock fuel set up
hey guys just wanted to see what people are making on the stock fuel set up, of cause most people add a fuel pump to run higher duty on the injectors. but on the stock rails reg and injectors whats the most u have got out of them?
im making 260rwhp here in Australia on a dyno dynamics dyno at 80 duty
cheers

for me 321ps (close to 320rwhp) - that's where stillway stopped, limited by the stock setup (and they should know what they are doing). That's with the benefit of 102~ RON fuel though.
seriesvii over at ausrotary made ~250rwkw on the (somewhat happy) c&v dyno (321ps = 236rwkw) - and that was at some insane duty level (99% or something like that) on the stock setup. To his credit, he ran a 11.2 with that. Haven't heard anything since though.....

You'll have to determine what 'safe' is for your car.

Haven't dyno'd but running 1 bar on a 62-1 and not even at 80 percent with a supra pump (haltech).
I'm running about 11.2 afr. Alot depends on how rich you tune for.
I'm in the 300's according to my time slip of 12.88 110mph
projected fuel would require me to run 16psi before hitting 80 pecent duty cycle on my secondaries. I could get more fuel if i ran primaries harder but It's a street car and 1 bar is my saftey zone.
Here is the post i asked the question
https://www.rx7club.com/3rd-generation-specific-1993-2002-16/injector-duty-cycle-571337/
To basically sum it up I have plenty of fuel for my car. Can even go to 10's if i wanted and still be below 80 percent duty cycle.
I think most ppl just increase secondaries until they run out of room. I increased the primaires alot so they both hit about 70's instead of one set of injectors doing alot of work.
This actually makes it easier for transition on the stagging of the injectors.
Most ppl have no clue what they are talking about so I personally would do your own reaseach as this forum is really bad about wrong information and the reason most ppl stop using it once they "Get a clue"

321whp SAE corrected @ 10psi
Stock twins
Stock fuel
Bolt-ons
Yeah, I know it sounds crazy... I didn't believe it either. But since that dyno I have pulled (barely) on a 12.2 sec MR2 turbo and destroyed a (roughly)300whp s14 240 (turbo KA).
During the MR2 run I was running somewhere around 13psi.
Yes, I have a wideband.
