ok so before I go into Ill spec my car out

1990 with 150k miles(been turboed past 40k)
greddy kit
rx7 intercooler with jims pipes
baileys BOV
newish NB FP
vortech FPR with multidisk pack running 10-1
305 supra green tops
Bipes pulling 7* with a 16* static
waste gate set to 7psi
r-speed cheapo narrow band O2 sensor

so I recently put in the 305 supra injectors to cure my lean issues. while doing so I cured a leaky inector problem that I think was the main cause, besides the fact that 205's suck ***** past 7psi. I didnt have any of the associated idle problems after installing the 305's (luckliy). but my main question is if it runs fine with 305's would I be able to kick it up to 9 (or god forbid 10 ) psi?...right now she runs on the rich side. and 305s with 70-80 psi put out by the FPR (theroreictly) the right amount of fuel for 200whp...I should be good to go. does this sound about right ?...yes yes i know I need a Wideband god do I need a wide band. not to mention a MS wouldnt hurt.....but just looking for any input...thanks!

in the least you gotta do some math, see my faq.

Uh yeah 10 psi should be fine but you realy need to crunch the numbers dude.
The only thing more dangerous to your car than hot air is a bench raced assumption from us. Do the math read the FP etc, and make the decission for yourself. As for me i'd do it but i am abit Crazy anyway

yeah. did all the numbers. I got got good pressure up to 90ish and the injectors i have have room to spare. so i kicked it up to 8.5 yesterday for ***** and giggles. pulls hard and runs rich. so I may get a hair in my *** and kick it up another PSI. was pulling a audi S4 or S6 last night... not hard but a steady pull through 4th into 5th..... so I may putt around with it for a while as is. i use to run 7.5-8 psi on a stock pump with stock injectors(talk about not safe and boy did the mani like to glow) so im sure it can handle 10psi with the 305's. enh....time will tell. I seem to tinker a lil to much sometimes....now if thie stupied mani bolts dont start that loosing up crap ill be good.

remember, your stock pump cant flow past 75-80psi.

it peaks out a lil below 90 when i clamp down. I replaced my stock one from a newer 1.8 (same pump i know) miata recently is my only explanation....I thought it wierd too cause the 1.6 original maxed out at likt 65psi tops.....either way im pleased :() and havent heard ping yet......
