Remap gains on a standard car
 

Just out of idle curiousity, what sort of gains could I expect to see remapping a standard Wrx PPP?

Ta

10 maybe 15 bhp, really not worth it unless your going to do something with turbo, top mount, injectors, and de-cat up pipe, your talking £600+ including dyno time for ecutec or £300/350 road mapped open source, at very least you'll need a new fuel pump too.

If your going to do it go the whole hog but that's going to cost about a grand and you'll get it around 330bhp mark, which imo is worth the cost of mapping.:thumb:

or you could go my route which is better brakes and then handling mods, they say brakes alone is equivalent to 50bhp and a good chassis set up can be worth even more.;)

One step ahead of ya. ;) Already done all the chassis mods that I'm prepared to do (brakes/arbs/suspension). Makes far more sense refining the chassis before doing much else.

Absolutely, the biggest obstacle for my car going quicker is not the power level, it's the wayward handling. Wagon specific PCA Developments springs are next, along with a few other tasty bits and bobs.;)

My biggest problem was brakes, the standard 4 pots on the Wrx are woeful for the weight/performance of the car. Stuck a set of 4 pot APs on it and it's so much better under braking.

Yep mine came with AP4 pots on :D so I know exactly what your talking about, now my problem is too much body roll, I have done camber bolts all round and a few polly bushes also running loads of camber front and rear, but I need 6 degrees of caster in my life and a lot less roll before I start thinking about more power, as I could be going significantly faster if it was a bit flatter in the turns and not squirming everywhere.:lol1:

On another note, I've had a re-mapped wrx but that went from standard 225bhp to circa 280bhp back in the days when PPP was £1500, while it was quicker than my current one the brakes and handling were terrible and it was positively dangerous in my hands, smoking brakes and screeching tyres everywhere :lol1:

It also needed a rebuild at around 30k, it had all the 5k oil changes and was always run on shell optimax, was also mapped by a reputable mapper at the time, which is why i'm shying away from mapping this one, well that and the fact it has 111k on the clock. oh and I had it from new so knew all the history, that was back in 2004 so maybe things have moved on a tad.

My 03 WRX PPP made 187 (240bhp?) at the wheels and after a remap 218 at the wheels (280?) Only change for map was Backbox and panel filter. Boost went from 0.9 bar to 1.0 bar.


Even though I asked for 1.4 bar.

Is the PPP not at 1.3bar of boost as standard? I know my friends standard PPP certainly is.

Matt you may find your PPP is actually only a wrx that back box will have gave you at least 25 bhp,the mapper probably thought anyone who is dumb enough to think a 187 bhp 0.9 bar wrx was PPP certified only deserved a bar

how do you print screen

I'd be totally shocked if it was.

:luxhello::lol1:

My car ran similar boost PPP when I bought it

What 0.9 or 1.3?

1.3 bar, dropped up the revs due to the tiny turbo and massive catalytic exhaust restriction

.9 is std wrx boost as far as I'm
Aware?

Boosted speaks the truth,do you have the certificate Matt?

It wasn't even 0.9, dyno run at AET showed 0.86

AFAIK my car hasn't had a restrictor pill in the vac hose until recently so maybe it was 1.3 bar once upon a time and that would have been enough to meet the claimed 265bhp PPP figure.

I am reading it right aren't I? I don't have to work out altitude effects etc?

Manifold Abs. Pressure PSI 12.6 = 8.68bar

8.86bar. Now that would be fun.
Well, for the handful of milliseconds while it lasted lol.

But yeah, 12.6psi = 0.86bar.

Unusually

Ha ha, yeah 0.86. 8.86 would be fun for 3 seconds :eek:. I'll post a pic of the graph later!

It tails off to 0.68 bar which seems a bit scant.

After it got remapped at AET boost went to 1.02 tailing off to 0.85 but made 218.4 (270-280bhp @fly) at the wheels, that seems strange power too for a low boost TD04 with 2 cats still on.

Unless the graph is at the flywheel (which I don't think AET do) which means I ran an underpowered WRX at the strip to 13.7

mega confused. :confused:

Anything below 200kpa is classed as NA

Isn't 200kpa around 2bar?

It's exactly 2 bar absolute pressure, so 1 bar boost at sea level. 100kpa being atmospheric.
This was a joke

lol

What's with all the noobs breaking my balls recently or creating baiting threads!!!

You try to hard Matt I saw this and it reminded me of you

On a side note does anyone have a Andy forest td04 for sale?

RTL, I remember that channel when SKY first came out.
