What's the benefit from fitting a PH1 172 air box on a 182??

Hi all. As title really. Iv heard this a few times now.
Thoughts?

Makes it twice as fast and leaves sti imprezas for dead.... get it done. Now !

Friend of mine did consecutive RR runs with the two and this was the result on his trophy:

Quick update, Been over at RSTuning today to have it on the RR.

Did 2 separate runs one with the Ph1/v6 box the other with the ph2 airbox. There's no difference in it, Ph1 airbox has less low down torque but 1 bhp more vs the Ph2. So the Ph2 is back on.

Car made: 178.5bhp < Ph2 setup

and 179.6bhp < PH1 Setup

Also found out the car has a map on it, no idea what map but it revs to 7.5k

Figures are with the above map and a decat back scorpion rs192.

So basically nothing, just less money in your wallet lol.

Sound is better I think

 

[Jon.G]

There was slightly more torque (1-2 ft-lb) lower down with the Ph1 box, but you wouldn't buy it for that reason. Sounds much better though.

I might fit a ph1 box at some point. Needs induction noise.

If you want noise, get an open cone filter not a box.

 

[mattjk]

or just pull the hoses off the ph2 airbox. cheaper and effective.

I want more noise, not as much as possible with plenty of heat soak to match.

I might go for the whole ktec btcc inspired bag of lies style at some point though.

Fit an up rated panel filter and remove the air feeds to the standard air box. Plenty of noise, looks standard and no heat soak. Very cheap too.

(For the lols, remove the feeds, and the air filter then go up a dual carriageway, the noise is insane! Lol)

I swapped from the Ph2 airbox to the Ph1 version.

For the sake of £50 I thought it's a nice little upgrade. Doubt there is much if any performance gains but like I say for £50 it sounds a little better and dare I say I think the tube box design looks better than the square type design.

Ah right. Sooo ill just panel filter it. The noise of the induction on the Williams is properly loud I dont want that again for a daily driver.
So this 178-179bhp is this at fly or wheels?

Its a guess of flyhweel based on a much lower value measured at the wheels, of approx 151-152 I would imagine.

178 @ Wheels would require either forced induction or throttle bodies and cams realistically. (or just a roller that chats nonsense)

I hated the sound with my airbox pipes removed. With my Remus exhaust it sounded like the exhaust was too big at low revs with any kind of load. It sounded cheap and nasty like a civic with a 3" fart cannon. Once up to speed it was fine, but it made me cringe every time.

 

[Alex_X93]

Its perfect for the job really as above fit a panel filter get some caf ducting revs much more freely. The stay cold ducting coupled with decent panel filter made huge improvment on my old ph1 almost standard sounding until WOT ITS ALIVE!

This is mine

Need to sort the hesitation at 5200rpm before I play with it :/
