How much power does the american WRX have? I see all these ads saying 227 hp, but then i see import magazines, and they say theyve got like 216 after a vishnu satge zero mod and aftermaket pipe. So whats the deal? Is it around 180, or is it the manufacturers given 227? Thanks

I believe you are referring to Sport Compact Car's mods on the WRX? If so, they rate power to the wheels hence the numbers will be lower.

227 is the manufacturer specification, which is typically taken at the flywheel. The other numbers you're reading are likely taken from a dynomometer, which measures power to the wheels. Stock bhp is well below 227.

Yup, normally it's around 15%, but AWD is even more. I think SCC got around 175 or so from a stock WRX at the wheels. The Vishnu kit supposedly adds about 40 wheel horsepower, which for the money is good.

Wow, but its performance is still the same correct? Around 5.7 sec 0-60? Thanks for clearing that up for me. :D

Mikey,
Yes, the performance is the same...meaning its all relative...the car still will have ATLEAST 227 to the flywheel, meaning they are getting around 150-175 to the wheels because of driveline loss (friction, etc). Now, if Sport Compant Car is getting 216 out of a WRX with a Vishnu Stage 0 then that means they are getting around 260 to the flywheel...which means that no the 0-60 is probably not the same as the stock WRX...its BETTER!!

Another thing to think of Mikey is power is all how you can apply it...awd can really apply power well, but it sucks a bit of power to use it.

Check out :http://cobbtuning.com/aps-cobb/aps/rtperformance.html

With Cobb's RT kit the WRX makes 256 hp to the wheels, yet can run a claimed 0-60 in 4.31 seconds!!! So, although the 256 doesn't sound impressive compared to the stock "227hp" it is much better. That 256 is compared to a stock (to the wheels) hp of 176hp.

Woah, that has really opened my eyes. I have always been comparing it to 227 instead of ~176. Now I got a new view on things. Thanks! :D :D
