power band

Does anybody have a copy of the dyno graphs for the 2004 WRX?

http://www.offroadvw.net/bajawes/V6_baja/compare.html toward the bottom there is a hp and touque chart compared to two other cars but u can see the powerbands

Sweet, thanks. The WRX motor just kills that Mazda V6 on those graphs. The guy was praising the Mazda for its low-end grunt, but for anything other than going to the store to buy groceries (ie, any kind of racing), the needle never goes below 3,000RPM anyway.

yeah aint that the truth, its not even a comparison. Low end grunt doesnt mean $#!& without AWD....jsut gonna sit there and spin em'

***NOTE - These charts and estimated vehicle accelerations have been updated, as I do not believe the original dyno chart I had for the KLZE was accurate. I think the car that was tested must have had a few additional modifications. I also updated the Subaru charts to show the jap spec engine, as I figure that's what most people would actually put in anyway. The Jap EJ20T has slightly higher compression and probably runs different boost.

The VW engine dyno chart came from Hot VW's magazine for a 1915cc VW motor with Street Eliminator heads and 44IDF webers.

The Subaru dyno chart came from here

The Mazda dyno chart basically came from here . But that chart is for the lower compression, smaller port, smaller cam KL03/KLDE Australian spec motor (also US spec). I then had to modify the higher end of the power curve to get the quoted 22.8kgf.m of torque @ 4800-5500 (depends on specific model), and 200HP @ 6500rpm for the KLZE version of the engine. So the KLZE probably has more torque in the low end and mid range than what is shown in the charts below, and various peoples dyno testing has shown this.

Modified the charts.... eh?
