Thread: dyno'd my 200SX

i made 245.93whp & 229.09 Tq (4th gear pull to 7k)

usdm de (lowport bitches)
t25
370cc's @ 3 bar
jwt s4's
3 inch downpipe
3 inch side exit exhaust
DE maf
calum basic ecu

it says my air/fuel was about 13 flat, thats way to lean? the car started getting real hot after the 1st run and i lost 11whp

yeah those are good numbers but its becuase its so lean.

drop it down to 11.5 or so nice and safe. ur power should drop but itll be much safer.

stratton.

thanks, i put the sheet up

nice numbers

looks good. Get those AFR to around 11.7 or so like Serban said. You will lose about 10whp or so but you won't melt it.

^ u mean stratton... i think...

Those are great numbers. Do you have Data Scan? I'd be curious to see your MAF voltage and injector duty cycle. It's probably lean because you're maxing something out!

yeah i got the bored de maf and 4 bar chips but my a/f was like 10.1, so im back to my old chips with 3 bar and DE maf chips. But im still waiting for them.

Nice.. the DE maf is only good for 250whp, which is the main reason for being lean. Time for a z32 maf, run the 370's @ 4bar and your fuel/air issues will be good until you get to 280whp and then its time for injector upgrade. how much boost were you running on the dyno?
