Finally got my car dynoed. got in 3 runs with some slight afc adjustments after the first run. Showing just the first and 3rd runs.
was done with a 3rd gear pull.

mods are:
SR redtop, stock T25, mbc set to 14psi, FMIC, Tomei exhaust mani, megan turbo elbow, greddy 3inch downpipe, test pipe, 3inch RSR exmag exahust, megan light weight pulleys, NISMO lightweight flywheel, SAFC, walbro 255lph fuel pump, and some other suspension mods which are irrelevant here.

Thats it? 230Hp thats alot of money for just 30Hp gain... No disrespect intended just suprised I would have expected a little closer to 250Hp even on a T25. But hey better than an N/A Ka ^_^b

Sounds about right with those mods but I'm liking the torque a lot. :)

torque looks great... i wonder if you would get the same results if you had the megan manifold instead of the tomei....

huh?
30hp gain from what? stock?
you do realize he posted dyno results, not crank results,
so doing basic assumption calculations 230 with 15% drive train loss, he's putting up ~270 crank hp comparing to stock 200

also realize, to OP, do you have any intake mods, like air filter or anything?
that my increase it a blip...

but those results are good, the max (maf and injectors) with that setup is 250whp, so it's all good

it would be interesting to see if you remove the AFC completely and compare the exact same set up to a properly tuned ROM.

...

It might be a wierd interesting experiment.

oh yah, I just remembered that the ECU is a mine's ECU that came with the engine... so who knows if that's making a difference not..

and yes, i do have a generic cone air filter.

what you need to do is junk that mine's ecu unless you know someone who can hook it up and retune/reprogram the board, it could be tuned for a setup much different from yours...

or just go to enthalpy to get the ecu tuned so you can also junk the afc, lol

yeah junk it, i had one that was from japan, not tuned for US gas it wrecked my exaust temps and the timing map all wrong for almost anything

why do 3rd gear runs? 4th gear is direct drive no?

yah, i plan on going with an enthalpy tune when i upgrade the turbo.. for now though i think i'll be focusing on suspension parts and a paint job...
