Dyno #'s on EVO Options

258whp and 270lb/ft all stock.
Free mods = 280whp and 287lb/ft
Overall I'm very impressed with the car so far and it seems to have
great potential.
BTW that works out to be around 290hp at the crank for a factory
stock one, looks like they underrated it a little.

I got this off the Chicago DSM Yahoo-groups list (Post titled EVO VIII Dyno #'s). Martin is co-owner of AMS ( www.automotosports.com ) in Chicago. I'm not quite sure what free-mods entail on the EVO's. Maybe they have some restrictions in the intake that can be removed and possibly a BCS restrictor, both similar to a stock DSM. I asked him about it on the list and am awating a reply. Anyway it sounds like the EVO owners won't have to spend any money to reach or even surpass the same power levels as the STI considering the 290 hp at the crank corresponds to the 258 at the wheels taking AWD drivetrain loss into consideration.

Update: This was done on AMS's 2 wheel dyno. So the whp is higher than it would be on an 4 wheel dyno due to less drivetrain loss. This actually makes the crank hp translation make better sense because as those numbers sit the drivetrain loss is about 12%. True AWD drivetrain loss would be higher than this, yielding a lower whp for the same crank hp. I don't believe the numbers to be exact but I think they are a decent approximation of what the EVO is putting out. Plus, its nice to see the 20 hp that can be gained with mere free mods. (Still haven't heard any details on these)
