Default IS250 dyno/rwhp

just curious, does anyone know what is the rwhp for the 250? i know the spec says 204hp but i seriously thinks that my 1996 ES300 pulls harder with 188hp

thanks

Good question, however I seem to think that the IS250 actually has more than 204hp. I feel like it has 225hp or so, and Im coming from a 500hp EVO saying that lol

It might very well pull harder. With different gearing the cars will accelerate differently and feel different. One with less power might push you back in the seat harder because it has lower overall gearing, but it doesn't mean it has more power.

i think you are being a little too optimistic on that one

is the 204hp at the crank? if so the wheel might only get 170-180?

It's probably around 175..and that's high hopes too, RWD cars lose a bit more through the drivetrain than FWD. The car I had before (RSX Type-S) was rated at 200hp, but stock dyno ran at 182wheel on dynapacks.

Remember now guys, they changed how they rate hp in america. My 350 is listed at 306 but in japan its listed at 318 and we in hawaii get the JDM ecu.

JDM ECM in Hawaii? You're no longer required to meet US EPA standards? How is that?

I dunno but we got what we got... and thats what we got, thus the TOMS sc will work on our cars. It was discussed at length in another thread... somewhere... something about we have to get the JDM LS smartcard for hawaii cars/our cars come direct and not thru cali... something like that.

^^yeah, I get that your cars are through Servco, but how could they not meet EPA testing? All US vehicles have to meet EPA, and if they use a different ECM, they'd have to test the Hawaii vehicles separately. That would be absurdly expensive from a compliance cost perspective.
