what's the stock whp for the evo IX?

 

You have one? And don't know?

 

i saw hks dyno 242/248 last year on the 9 mr

 

ya, 286 that's flywheel hp?

 

Probably around 250-265 to the wheels...

I never dyno'd mine in stock form but I know it was in the 250 range based upon it's performance. It was able to pull on my stage 2 STi which dyno'd at 253 whp two days later.

 

I had my evo dyno @ 219 to the wheels (heartbreaker dyno). WHP isn't everything as every dyno is different.

the 286 figure they advertise is the power at the crank, unfortunately our evos have a lot of drivetrain loss

 

HP loss through drivetrain may add up to 12%! However the amount may vary along the torque/horsepower curve for a given engine. It is best measured on a dyno. I could certainly not quote any numbers for the EVO

 

Depends on what dyno you use.

The weather conditions also make a difference.

 

A stock Evo will do about 255 hp to the wheels on a Dynojet.
