Impreza WRX-S Hatch - rolling road result surprise
Hi everyone,
I took my car on a rolling road recently and expected to get around 260 BHP based on the standard specification. However, the rolling road showed my car running 304 BHP and around 306 foot pounds of torque. I definitely wasn't expecting that and was wondering if anyone has any idea if that sort of power is sensible with this engine? Boost pressure seems to be pretty high too (between 23-29 psi in some instances) and I basically don't want the whole thing to give up and explode.
Thanks in advance.

Because 304bhp sounds like VF territory.

Thanks for the comments guys. I'm not sure which turbo the WRX-S has but will try and find out. Ditch I thought that something must have been modified at some point!

I though the wrx s had tdo4 and potential for sti power with re map. My guess would be the previous owner re mapped for safety I'd say the standard s would be capable up to 350bhp. I might be wrong. I'd be happy but I'd try and find out who mapped it.

Thanks for the comments everyone. The boost is normal generally (I'm told) but under hard acceleration it does go up (as you'd expect) to around 2 bar like you said.
I just bought the car and I haven't modified it at all!

I've attached a scan. The rolling road people said they wouldn't go above 300 bhp on the car and were going to ask a Subaru specialist about the turbo pressure because they thought it was high. They said they'd worked on STIs and standard WRXs but weren't familiar with the S model.

basicly yeah, should be smooth curve. Did you get a boost/fuel graph?
wrxs is just effectivly a ppp'd hatch, so if the s has foxed em i'd take it somewhere that knows what there doing.

Thank you.
No that's all I got with it. They took a reading for boost on a short test drive but they didn't give me that, they're going to check and get back to me though. I did explain some of what I thought the differences were (with the Prodrive pack etc) but they wanted to check.
I guess I'll have to try somewhere else!

graph is just strange full stop, looks like a roller coaster, not sure how much is the way its displayed or if the maps fecked
