Hey there, fellow STi freaks. I was just talking on the phone to one of the lead techs at my dealership here in CO and out of the blue he says, "so the STi is coming next year." He told me they received a book on the car from SOA, and it'll have 276hp, 6sp tranny, variable valve timing (can't recall what Subaru calls it), and "carbon fibre strut springs." Those are his words exactly, but I think he meant strut *bar* instead of springs, but I could be wrong. I'll ask to take a look at the book when I bring the car in next week for some service.

I'll keep everyone posted,
-Chris

Well, if the EVO came with the full hp like the rumors say, then I cold see the STi coming with the full hp as well.

i really really hope it will have 300+ hp it would be great if they gave us the full version instead of watering it down like they usually do

SOA said the WRX would have 227, it has 227. It's apparently printed in this "book" that the STi will have 276, so I bet it'll have 276. There is no gentleman's agreement here in America.

Don't get PS (some German term, Pferstardte) confused with hp. Also, don't get bhp (braking horsepower) mistaken for hp; bhp will always be lower.
AND... the spec will depend on the fuel, right? If you're running with 76 Racing as opposed to the more typical 98RON, I believe the UK model would get 276 PS instead of 265 PS.
What is curious, though, is why the 218hp UK WRX translates to a 227hp NA model, but a 262hp STi wouldn't give us a 276hp STi....

Hello all, I went to my Subaru dealer today to inquire about the WRX and to see if they knew anything about the STI. When I got there they had 7 WRX's sitting on the lot, all sedans and all had 5 speeds. I then then asked the salesman if he knew anything about the STI. He said the WRX STI would be released in the spring of 2003. He also said it would have 280hp and it would be based on the Legacy instead of the Impreza. He took my name and number and said he would contact me when he knows more. The dealer is Sommer's Buick Pontiac Subaru. He also said they were Wisconsin's largest Subaru dealer and they get alot of WRX's. As I said there were 7 sitting on the lot today. Pricing on the WRX is MSRP. Oh yea, he also said the pricing for the STI would be in the low to mid $30's. That's all I know, I'm not wild about the price. I was hoping they could keep it under 30k. Anyone hear anything to support what I heard today.

Sounds like he has no clue what he's talking about, which is pretty much de facto with most salesmen. Not ALL salesmen obviously, but most of them...

Titanium-
Who's post are you referring to? Subaru wouldn't refer to "PS" in this STi book at the dealership, they'd refer to "BHP". And I don't care why the UK spec WRX has less HP than the US spec WRX. I'll be putting in 91 octane just like I do with my RS now, plus I'll probably be dumping some octane booster in as well.

To nobody's in particular, but I've read some items, usually based on JDM versions, which give the spec in PS. In other articles referring to the same items, the same number was used, but bhp or occasionally hp was appended instead of PS.

Also, would the spec book here really give the bhp and not the hp? Doesn't the manufacturer quote the hp developed at the camshaft to get a higher value than that obtained from a dynamometer?

When I used to subscribe to the 4 main car rags (Automobile, Road & Track, Car & Driver & Motor Trend) they all seemed to use HP & BHP interchangeably. I honestly have no idea if they're the same or not.

I've no doubt that the car manufacturers would rate the horsepower of their cars wherever it's highest, not taking into account the drivetrain loss (esp in our AWD cars).

It's not, usually. Horsepower can be rated from anywhere, and would give a better number if measured before losses. Braking horsepower (bhp) is actually the measure of power required to stop the motion. If only 200bhp is delivered to the wheels, then that amount is what the dyno must exert to resist equally the car's useable power.

I believe they use the term BASE Horse Power. And it's usually measured at the flywheel. I believe you're refering to Wheel Horse Power. That is measured on a rolling dyno and is considerably lower because of drivetrain losses.

Metric horsepower is slightly lower than English horsepower by a factor of 1.068, or .9836 depending on which way you go.

Giving the UK STI ~283hp. I don't know how strict CA emission are compared to UK, but... I'd expect a lower number than that.

Realize that the JDM spec STi and EVO7 have about ~300hp as per the manufacturers "gentlemens" agreement.

The JDM spec WRX has 267hp and the USDM spec WRX has 227hp. 40hp of difference to pass emissions laws among other things.

So speculate on that.

I hate it when I mix up conversion tables...

JDM WRX = 250ps x .9863 = 247hp
UK WRX = 218ps x .9863 = 215hp ?!?!?!
USDM WRX = 227hp
JDM WRX STi = 280ps x .9863 = 276hp
UK WRX STi = 265ps x .9863 = 261hp ?!?!?!
USDM WRX STi = ~265hp ???

Still significant losses between Japanese and US and especially UK markets. What is up with the UK? Or did I just do my conversions wrong again?

I got the conversion factors from here :

In all my years as a automobile enthusiast (read: freak) I've NEVER come across nor heard the term Base HP. BHP=brake hp, at least in US car magazines. I'm not calling you a liar, I've just never heard that term before and I've read a lot of car mags.

Maybe I saw it somewhere refered vaguely in that way and my mind latched onto it as a plausible word to complete the acronym. It does things like that. More than likely some term I read years and years ago that stuck with me, and has never been challenged since the acronym itself was only used.

http://www.ucc.ie/cgi-bin/acronym?BHP

So, I was wrong. Funny that I have to know a bunch of ne
tworking acronyms but don't know this common one.

So, the question is still valid as to if horsepower and brake horsepower are the same. I would assume they would be but I assumed what the acronym bhp was for years... How I wish the metric system was more prominient. It would have saved me the embarrasment.

So, I'll echo TiTaNiuM sAMuRai, "You learn something new every day..."
