Ohh yeah i am now running the rx7 460's. I had to take my rrfpr of as with it attached i was severly drownign the car on top. even pulling the max of fuel. But it works rx-7 afm and safcII+460cc high impedance injectors works great. so far 14 psi seems to be about my limit before i detonate so i might need to tweak my WI pressures or get a progressive but i am just happy it works yippee.

Very curious. So you're running just the stock fuel press reg? How's idle and low rpm throttle response?

idle is the same as ever i have my aic blocked of so i hunts abit but atleast with the safc i can richen it up to where i can run the AC at stop lights this was a problem before. throttle response is unchanged on low rpm. yeah my 255 hp gives me a idle reading of 47-50 psi and the stock fpr is 1-1 rissing rate so by 15 psi i have 63-65 psi of fp.

how much is the work is the S-AFC doing? Good idea pulling the FMU, those injectors shouldn't need more than 50psi to do their job.

You're tweaking to run higher than 14 psi?

If you hit another wall (like at 18 lbs ) think about an I/C? Just curious.

Getting 460s to work is sweet. Nice!!

the safc is at -23 at 800 and then i have it gradualy ramping up to 0 by 3200 and then up to +20 past 4500 as by there i have 13-14 psi. i will probably need to turn up my pump pressure or get a progressive from WOT. hopefully by spring i will have a dual feed fual rail thanks BRG that came in today os i have another project.

i forgot to mention thanks guys if it hadnt been for this site and m.net i would still be a slow loud NA. but faith steped in and i seen andy running 330's with rx7 afm and ccpull runing 660's with his clocked ecu, and vafc, and 93mimi you all had a small part in my succes and saved me alot of headache. You guys are awsome.

Not trying to tell him to use an I/C or anything, just curious as to whether it would help north of 14. Mag5 seems to be doing fine without!

I'm pulling for ya, The setup is plenty impressive as is

i wanna see how far i can take it. then get an IC if need be and be more conservative with the WI by that time i hope to have a 6 speed and 3.9 rear and some DR's as well as a evo3 i tend to go to extremes on stuff when i get into it, i gues you could say it is abit of a weakness with me, pushing the limit.

Without anymore tweaking I think I'm limited to about 10psi. Damn RX-7 AFM puts me so rich after 5.5k, although there is a tweak for that. Looks like I'll be squrting as soon as I do a torsen swap, it will make my life easier. At least for now I'll just focus on other things. Like wondering why I have no oil...

Man, that's insane. It just goes to show how little I know about everything in general, and Turbo Miatas in particular.

That setup sounds like a ticking timebomb to me, but see the above about me not knowing jack.

What are you doing for timing?

stock timming set at 10 degrees base. WI is just that effecient granted i run 93 octane but still. it has surprised me and far surpassed my expectations if i didnt mother my car like i do and wasnt so ---- about what gas and other fluids i put in it then i might have abit of a problem but i am very particular about what my B6 gets for fluids and try not to destroy my diff.
