your right bro, puerto ricans do like to do crazy oversetups but im really not looking for that i just want to take the much hp of my TII with it being stock. stock injectors, stock turbo, stock ports etc. believe it or not my car is known in my area because is the only rx7 running with a safc lol nobody else have a safc they all go with microtech etc. when people see that my car runs with a safc theyre like "what the hell a TII running with a safc thats incredible" the dyno guy was amazed that my car run with a safc he thought the safc was useless with a rotary. i just want to do good numbers whit my car stock nothing else. i just like when peolpe ask me if i have a satandalone and i say no i have a safc lol theyre is = priceless.

The reason why they are all so shocked is because they know that TII with mods + safc = ticking time bomb.

You probably want to keep everything stockish and keep costs down and safc will be good for that(until the engine goes kaboom). But I'd never use it for an extended period of time. The tuning accuracy and abilities the safc has is pathetic in comparison to what a microtech has to offfer and the rotary engine NEEDS that accuracy!

I had an SAFC2 in my car and its being ripped out now to make way for a microtech.

Oh, and 14 PSI on stock turbo may be ok. But like RETed said whith the addition of the FMIC you may end up overspinning that stocker turbo as it tries to fill the extra volume of air needed. I've seen 16 psi kill a stock turbo with a stock TMIC so I'd say 14 psi with the fmic and the extra needed air volume will probably kill the stock turbo too.

22% increase in the safc does NOT mean 22% injector duty cycle, please do not call people names for arguing that your wrong.

Now might be a good time to ditch that safc, get a mircotech, and upgrade your turbo since you have all the other bolt ons.

soory bro but im sticking with the safc, i don't need a standalone for the mods i have, the safc is doing the job pretty damn well, and tell me why the engine is going to do kaboom? im running just 12 psi but the boost ''spike'' i have is ridiocously. the psi goes to like 7psi at 7000 rpms. i have all the bolt-ons, i have a fuel cotroller so why is the engine going to go kaboom??? don't think is going to be mine.

rx7legend

they're are guys here that have TII and they're running a safc whit my same mods or more and they haven't do kaboom so why your saying that.

Well... Most of them have upgraded their secondary injectors.

I have been running a Panspeed hybrid turbo with a RB 3inch back exhaust on a street ported S5 motor with the stock injectors. I have a super old HKS PF-Con with a GCC and I have had no problems.....ever. I run 14 psi eveyday and run it hard. I have a AEM wideband and its at 11.0 flat. Just have the aproppriate monitoring tools and you will be safe. The life of the turbo won't be long but thats life, the way some people drive these cars longevity isn't expected. Mine won't be around long too.

I assumed you didn't understand the SAFC readings.

rxspeed87

think of it this way if your SAFC allows you to do +/- 50% and lets say your putting it at -20% for isntance. that would mean (following your logic) that your duty cycle is -20%. I don't see that happening. duty cycle is the amount of time your injectors are open vs closed
so 50% duty cycle is open half the time closed half the time. while an 85% duty cycle means they are open 85% of the time closed 15% of the time. so again if your SAFC allows you to set a (again following your logic) -20% duty cycle what does that mean?

maybe it is just the fuel enrichment/enleanment rather then duty cycle

not trying to fight here just show you something



EDIT: already seems to of been adressed

I've killed 3 stock turbos(S4's, now on a S5) running 14psi with a FMIC, always seem to be killing the oil seals in them. Oh well, if I cared I guess I could run 12psi and I bet they would last twice as long, I would just miss the way they wine at 14psi

RETed

What boost gauge are / were you using?
Where was the boost gauge plumbed into?

What kind of power is to be made at 14psi with a good tune?
