PPP Sti owner's advice please....
Hi all,
currently have a MY03 STi and I am picking up my new 05 STi next Tuesday. I currently have a Afterburner Vortex Backbox and STi panel filter on my non PPP car that I would like to switch onto my new PPP'd STi.
I have heard that such mods could cause a problem with the performance of the car and are not reccommended.
I have also heard that the engine management is adaptive and would benifit from the freer breathing.
So....
has anyone got any positive or negative opinions on the above based on experience, or just good old technical knowledge of new age STi's.
Cheers,
Dan

when I put the deposit down, they agreed to fit it for me saying no problem at all with warranty. Now the technicians are saying they can't be seen to be fitting non-Prodrive exhaust. Sales guy has said they think it will hamper performance but he can't understand why. So i'll fit it myself depending on the opinions of this thread.
A backbox is easy to fit anyway.... 10min job.

I'm sorry I can't help with your question.
However - being new around here - if you want to fit an STI panel filter, what is in the STI as standard?

For the hassle, leave it as supplied and flog the other bits.
The STI panel filter will not be popular with any warranty claim, as any messing with the filtration tends to get people up in arms. The MAF (which tells the ECU how much air is flowing, hence controlling fuelling) is sensitive to changes to the filtration/air flow/... You've got a brand new car, I'd leave it well alone. Besides, performance will *not* be affected by this.
The backbox will not affect performance in any significant manner, just make more noise.
None of the mods will do anything for the car other than void a bit of the warranty; there's no performance to be had from a back box or filter. I'd leave the car as standard whilst you've got your warranty, sell the bits on here, and spend the cash on having fun
. Or a few tanks of petrol
As for the "just a paper cheapo" comment. I can magically fold a paper one out of handmade parchment rolled on virgin's thighs, write STI on the side very neatly in crayon and flog it to you for 100 quid - would that make you happier? . The original is designed to flow more than enough air for the car, and filter to the appropriate levels, so what more do you want from a filter?

The explanation below is in layman terms (maynot be "Technically" correct) but I understood it.
As no 2 engines and Boost valves etc. aren't the same
PPP is "TEK2" or "off the peg" stlye. it will have a "Window or limits" for Peak boost and boost spike protection. If you Car is running at the low end of the range and you fit these bits you may see performance gains
but if your at the Top end you will get problems of boost spikes or overboost. The ECU then limit boost trying to keep it within the Range and effectively slowing your Car down.IMHO

On my non PPP 03 STi the backbox alone made little difference except noise. But oh what a noise.
However once the filter was replaced it definitely pulls slightly harder and revs much more freely at the top end.
Purely my opinion on my car.

It seems that quite a few people(over 30) took part in a group buy on here last year on the basis that they were better than the standard ones - by better it seems that it is claimed they can increase power by up to 5hp and allow a better throttle response.
Are you saying this isn't the case through experience.

Re: Group buy, are you 100% sure they were'nt for the older style STi's. Do a search in drivetrain and you'll see that changing air filter to a more flowing one is'nt a good idea on newer >MY01 cars.

To be honest, I can't see the point of modding a PPP'd UK car and writing off your warranty.

I agree with everyone on here There is no piont frsking losing Warranty for Indution or exhaust "Sound" 
Buy a AP22 meter or a Rolling road Day prior to a Mod and check before and after. You will find it may sound like it's got more Power but effectively the Car is far slower.
IMHO

Well, Bob Rawle recommends Sti panel filters for new age STis.
I fitted a Sti panel filter and Vortex Afterburner BB to my 02 STi.
Before the changes with a PE sports cat exhaust system and PE remap it gave 308hp and 293 lbft. After the above changes plus a Bob Rawle remap it gave 314 hp and 285 lbft, but peak boost was increased by 0.1 bar to 1.55 bar. On the road the increase in performance was very noticeable after the remap (but not before) and certainly felt alot more than from an increase of 8hp.
My conclusions are that you will need a remap to obtain any noticeable benefits and that rolling roads do not reflect on road performance due to the lower loads which affect boost.
