What happened to the A/F at 3200? Im no dyno expert in any means, but does going down mean going torwards the lean side?
That A/F looks a bit rough compared to others... do you have a S-AFC?
Again, Im just now learning all this A/F ****, and all the other stuff, so if Im asking a retarded question, please keep the flameage to a minimum

Actually he got really rich around 3200 RPMs. Around 11.5:1 is a good setup for the street. 12:1 is ok too, but his A/F is wayy too unsteady. Here is his other post that has mods:

My guess is either a heavy port job on a rebuild he may not know about or an off dyno. This is believeable for me, but 178rwhp completely stock on the same engine that came from the factory 14 years is ago is a hard one. I want to believe it, but damn.

i got so much TQ over hp because i had full boost (14psi) aroudn that rpm, 3-4k, then the boost pretty much dropped after that since it just cant keep up with the motor. Too small. by 7k i was doing 10psi. Who said rotarys cant make TQ?

that was his hihgest hp # , the a/f was smoothed after that, the s4 turbo just doesnt want to boost anymore that exhaust housign is just too small , well time for a bigger turbo. thi swas all at 14 psi. doesnt really make sence to push that turbo any more since it will just die this way he can atelst have enouf power and somewhat of a power band istead of a big spike in power of like 20 psi from about 3-5k
he has full raicng beat exhaust, 3 inch intake pipe on teh turbo compressor, and a greddy ic thats pretty much it for power mods

here is the comparison between his stock car with only a k&n drop in, then with rb exhaust at 9 psi then with addition of greddy intercooler and still 9 psi and then 14 psi

What other mods do you have? Which RB exhaust, the 3" or the 2.5 incher?
Thanks

Are you ever making the hp early in the rev band. Your peak hp is only at 3800rpm. How the Hell is this possible!?

They came with 182bhp. So approximately 160rwhp would be a good pull completely stock.

I'm with mr. eccentric, that peak HP is occuring curiously low. Why, I have no fekking clue.. but it may be a symptom of you overall oddball a/f & truck-like dyno chart.
