i have a S5 NA streetported with a RB full exhaust.
i was wondering what my a/f ratios woudl be aroudn right now. i am about to install a S-AFC on the car to see if i need to adjust the fuel when i dyno to try to get some more power atteh wheels. i have been driving the car around and power doesnt seem to fall off all the way up to the fuel cut 8600rpm? on the tach however accurate that is.

so my quastion is what do i tune the AFR to on this car, considering i will keep teh stock timign and will want to kepp running the 87 octane gas.

any other suggestions woudl eb great.

 

Hey Kahren goodluck! Get back to me with the dyno results, I still need to dyno mine. Soon I hope*

Goodluck!

Nick

 

I got the same setup as you...yes..yes ..please post results!

 

whats up with the 3-rotor?

 

Whos got the 3 Rotor?

Nick

 

what 3 rotor? huh

 

by when will you have the results?

 

i am going on the dyno march 1st. someone tell me what to tune the AFR to!!!

 

perfect would be 14.3

but anything around 13.5 to 14.0 would be ideal for an NA

and then u can tweak the timming as well...becareful though.

 

i wanna tune for power and reliablility i dont want the motor to pop. i dont wanna cahnge teh timign since i am already gonna run 87 octane and dont paln on goign any higher. i was thinking of tunniing to 13.5 from 5-8.5k rpm, 13.8 from 3.2-5k rpm and 14.1 under.

any one advising against thins pelase speak up
once again the motor is street ported, full exhaust, intake and pineapple 6 port sleeves

 

dyno tuning is fun

 

Kahren, I though you had a post about building a 3 rotor a whileback...maybe I'm just trippen

 

yes u are i wish i had a post.. though

 

Doh is was Kurgan, kinda similar heres the thread

kahren has one and a half rx7's

kurgan has one and a half 13b's

easy to get confused LOL

 

umm its more like 1.75, but i also got another 1/2 now?
u do the math?

 

Well here is the info I have, don't know if its accurate or not. Tune to 12.5-12.8 for NA's, and place the ignition pickup on the Trailing #1 cable.

Hope this helps!

 

well the more info the better
thanx
