I am running completely stock exceptfor the following on my 1993 RX7:

- Downpipe
- Midpipe
- Greddy Evo Catback exhaust
- Walbro 255 Fuel pump
- HKS Intake
- Power FC

I am wondering if someone out there has a similiar setup, and what I can get as far as horsepower gains with a good Power FC remapping? Any help would be great.... Thanks.....

 

280-300rwhp at 12psi of boost.

man i like your orange car!!

 

300rwhp at 12psi is a bit optimistic don't you think?

I'm runnin at 1 bar with a huge IC, emissions removed, no air pump, no cat, feed 80mm downpipe, apxi filters pfc etc etc and i doubt mine has any more than 300-310rwhp.

 

i cant believe your running that sutup without upgrading the injectors? its fuel cut a major issue in pre-detenation?

 

With a conservative tune and all the flow mods, I'm right at 300whp at 12psi. In fact, I never ported the wastegate so I'm still running a 2-3/8" restrictor plate. BTW I'm right at the edge of what the stock injectors can do, just reaching 90% peak duty on a cold night.

 

Boost creep is a bigger problem with an open exhaust. As I mentioned in my last post, I'm reaching 90% peak duty on stock injectors with a midpipe running 12psi. Removing the restrictor plate will open it up more, but then you need to port the wastegate to be able to control boost. IMO, anything past 12psi *with good flow* will require bigger injectors.

 

fuel cut is a function of the ECU, not of the injectors.

While it's arguably risky to be running stock injectors with his setup, as long as he keeps the AFRs in check, it's not going to hurt.

 

Thanks. Its currently for sale.

why are you selling it!!!!!

 

Does she come with it? ;o)

 

sold separately?:P

 

He's fine, just monitor the boost and with the power fc he should be fine. Since you have a power FC just go and get the car tuned and problem solved. According to the fuel cal. he should be fine up to 360 flywheel. Just watch your air fuel ratio and have the damn thing tuned its worth every penny considering 3 grand for an engine

 

any more pics of the car + the chick?

 

I have 2 kids now so its impossible for me to go cruising. I have to leave the old lady and the 2 kids behind which means I don't go cruising.

Unfortunately not.

Yes but I don't want to clutter this thread with pics of my car and her.

im sure shaneryantomson wont mind.

 

ha ha I like the chick getting out of the orange car!

holly good god batman!!!!!!!!!

r.k you da man!!

 

that your wife? also why not keep the car in the garage for a day or night that you can take it out and drive it? im not letting my wife or kids mess it up for me (when ever that happens) my gf knows this already

 

No thats not my wife.

Thats the problem I drive it once a week on a good week. Sometimes I go 2-3 weeks before I drive it again. I have to keep a friggen battary charger on it at all times otherwise the battery might go dead before I drive it again. You will be singing a different tune once you get married and have kids. I have to sacrifice something I love for something I love more and thats my wife and kids. Its just a car in the end.
