Thread: dyno'd my 200SX

This was done on 93?

Yeah, i know i hope thats the reason for it leaning out. i was running roughly 8psi




93 octane? if so yes

good numbers but yeah that is way too lean and asking to detonate or melt the piston completely, how much boost were you running im guessing 11-12psi, had you spiked higher i would have felt sorry for you because thats exactly how i detonated one of my motors was running that t25 too hard, but yeah definetly good numbers. get that a/f down a bit and run 12psi you will be good all the way, just dont spike any higher than 12 cuz it really wont be good. It will make buttloads of torque but with that comes heat due to the backpressure.

Nice numbers again, keep up the good work.

it definitly didn't spike higher then 10psi if it did spike. Which I don't think it did.

Nice! 100hp over stock? That's gotta be super-fun to drive!

nice numbers man, very impressive

so my wideband says my a/f is about 12.4-12.7



more than 100whp over stock. haha.



thanks man

What kind of wideband were they using on the dyno. A tail pipe sniffer can read lean because of its location.

i have no idea. My wideband is reading lower than what they have. I have a autometer wideband.

you could just have some exhaust leaks that are causing the high reading.
