Engine Flat-4-cyl, 2457cc, 16v, turbo
Max power 277bhp @ 6000rpm
Max torque 289lb ft @ 4000rpm
0-60 5.0sec (claimed)
Top speed 158mph (claimed)

Now both those sets of stats were taken from Evo and you can quite clearly see the acceleration of both cars is near as dammit the same with the Sti ultimately having the higher top speed (the extra gear ratio will do that)...
You've used the GB270 though? If we're using special editions, compare it to an RB320, spec C etc etc.

You need to compare standard for standard.

There's a reason for that, the PPP gets the WRX to a similar level of tune (on paper at least) to the STi. RS Matt and his WRX loving chums seem to believe that like for like, the WRX is the faster car. Those figures quite clearly show it isn't.

But ppp is also available on the sti. Which increases the bhp and performance too.
Mine had it and it was a rubbish map.
I had the car remapped and it made 352 bhp but was far more driver friendly.
This power level can be achieved on standard equipment way way more than a wrx would get near standard and the gearbox would die anyway

Exactly.

It's ridiculous to compare a GB270 to a standard STi. Even still, the standard STi is the faster car, but you have to compare like for like. As said FT says, put a PPP onto an STi and it becomes quicker, funnily enough like a WRX with PPP does aswell.

If you're using a GB270 to represent your case, then pick an RB320 as the STi to compare to. But you won't though, because you refuse to accept the cold, hard facts.

Figures mean nothing really it's the overall performance on the road that counts
The only reason the 0-60 times are similar is you need to grab third on the sti.
Not many buy them for drag racing and Matts beloved thread means nothing due to firstly his car is lightened and modified so comparing it to a standard sti is pointless and secondly he has made up the bhp of some of the sti too.

And as we said on the drag thread, the only comparison is on the same day at the same track....

There are drivers and there are screw drivers and all that....

Default MPG

I dream of getting 35+mpg in my MY07 WRX PPP wagon.
Best I've ever had, driving like an old granny was about 28mpg, and it's been mapped by Bob Rawle, who craps over anyone else I've seen so far when it comes to mapping.
It did improve after he mapped it by c10% but I just don't see (in a hawkeye WRX anyway), how 35+ mpg is achieved without ruining performance.
Maybe the blobs, bugs and classics are better?

I had another non-PPP WRX saloon before this and that also never got better (regardless of driving style) than 31mpg.

Guys, I realise you have differences in opinion but it's not edifying to seeing people slagging each other off in the forum tbh.

If you want good mpg it's all about short shifting, not boosting and overrun, so first thing you need to get is a boost gauge so you can see when you're boosting it, 2nd thing is to drive it like you do when it's cold and not go above 3krpm.

That doesn't have to mean you're going slowly, it just means you drive slightly differently and carry your speed, in my WRX PPP 80mph is just shy of 3krpm in 5th.

Driving like this you always have the power and torque available when needed as peak torque comes in quite low as does boost if you want it, there's also no point in pressing the gas only to brake soon after, especially when going down hill, so don't and just let it overrun as there is very little fuel being used.

Now this isnt always possible especially in town, but where I live out in the country with lots of mountain type roads 28mpg is still achievable, but like I said above it's about carrying speed, not breaking and then stamping the gas so you then go into boost.

It helps if the car is set up properly and that doesn't mean a set of coilovers and a huge turbo, to carry speed you need a car that's not twitching over bumps and changing line to avoid little pot holes or becomes unsettled when you do hit a bump or yump.

I can still get a pretty good move on without thrashing my car and even when I am out for some fun it rarely goes above 6krpm as there is no point beyond 6250 ish anyway and by that time I'm headed towards 3 figure speeds in 3rd and above on slimey country roads with tractors and a plethora of variables.

Point being, you don't have to cane it in every gear to drive fast and have some fun, that's the benefit of a small turbo, long gears, good tyres and a well set up chassis, a proper set of brakes can also help for those very few moments when I throw all the above out of the window and have a mental 10/15mins.

Because I like them, 4wd, reasonable boot capacity, even more so in wagon form, reasonable turn of speed when required for overtaking and a bit of fun when I'm in the mood, still pretty quick, especially off the mark even by modern day standards, which is handy in town and country with the amount of numptys on the road, can still get a move on in the wet and if it does snow I can still get home or go to the shops.

Having spent a fortune fixing one of them, then learning the hard way, there's not much I can't do on one myself, so it ends up being pretty cheap to run, especially when compared to cars of a similar performance, of which there are not that many (4wd).

I don't tear **** about the place because I need my licence, having lost it once many years ago and being out here, I'd be screwed and stuck in england without it, which isn't an option.

I also like the sound they make.

It was a general question about the whole thread not aimed at anybody in particular.
I don't understand the mpg concerns if you have an impreza.
To get anywhere normal mpg you need to drive off boost.
Then why have a turdo car in the first place if you can't afford to drive it normally

WOW Shocked at this statement ditchy!!!

I struggled to keep up with a mates 360bhp 360lb/ft JDM hawk STi in my 380bhp 412lb/ft UK hawk STi, considering your WRX has only a PPP from memory(265bhp??) that would mean that a UK hawk STi would need well over 400+bhp to pull away from a 265bhp WRX wagon.

In the 3 years he's been mapping I can only guess he mapped his Wagon for economy rather than power hence his mpg claims.

No that can't be correct as it kept up with a jdm sti with 140 bhp more.

Switchable maps.

The laughable thing is, it only took him 5/10 minutes to get the gist of mapping...(His words)

In the 11 years ive been on this site, the 1 thread that really stand out for me that makes me laugh out loud, is Ditchy's Rover 25 beating a Ferrari on the twisty roads story/thread Kills me every time, and now a blob WRX PPP wagon(265bhp) is quicker then a 400bhp JDM STi I can add to the funniest ScoobyNet posts of all time

Please dont ever ban Ditchy, he makes me laugh

What about the one where he was mocking some guy who posted in car footage of himself at The Ring, telling him his lines were all wrong.

Then Ditchmyster piped up and said that he can lap The Ring in his 320bhp Type R, in the wet, quicker than the Ring Taxi can in the dry...!

Most recently he mentioned he has mastered 50 or so fighting styles yet the mere mortal which is Bruce Lee only managed 4 or 5..

hold on the wrx wagon is considerably heavier than the saloon so if the wagon with 266bhp kept up with a jdm sti saloon with 400 bhp how much would you need in a wrx saloon??

i just cant keep up,would a rover 25 be faster than both cars too?

its most confusing as we actually had a wrx mapped to 270 bhp and an sti mapped to 352bhp and the wrx hadnt a hope in hell of catching the sti.

so does that mean a 350 bhp uk sti is far faster than a 400bhp jdm STI??

all i can think was we had a faulty wrx as ours was nowhere near as fast as the sti hence it was sold.

confusing as it was rr tuned and had a print out for 270 bhp too and lighter than a wagon.

i just dont understand.
