As Jamo correctly pointed out, all 3 main components of the RS2 airbox are different to the S2 (those being the trumpet and the 2 halves of the box itself). Even the heatshielding is different, making the filter the only common component.
The 2 halves have different volumes and the filter sits in a different place to increase the flow through the box and thus the benefit from the larger inlet trumpet.
I have been asking for some time to run some back to back tests at one of the RR sessions. I want to run the S2 vs the RS2 (we could even add a cone or a modded S2 box) on the same car. I even offered at the last session and brought my S2 airbox and MAF with me but we ran out of time.
Ideally I want to run the various airboxes on my stock car then swap to my homefries ECU and re run, but that would probably take an hour to get through 8 pulls on the RR and we don't normally run out of time without doing something like this.
If we ever do it, we could following up with an IC test on a stock plus homefries car (prolly the most common setup)

You'll need T-Stream or V-Stream homefries to get proper benefit of any IC upgrades...
Everybody has N-Stream homefries (except for a Beta tester or two).... Which reminds me Simon -if you have a spare ECU - I can bring you into the V-Stream Beta program if you wish. Ping me a PM if interested.Paul Nugent

All this talk about ABY / S2 airbox conversions got me thinking and this is the result
4" is £16 odd plus vat and del
6" is £22 odd plus vat and del
Steven at Pipe Eqpt is up for a group buy so this is just to find out how many of you are feeling the need for a DIY RS2 airbox so to speak.
Could be a good one to set up, not sure how you go about this but details anyway

I should have explained better...
N-Stream is the 'normal' homefry on ABY that so many folk are using - 430Nm and 280bhp with 98RON
T-Stream (in Beta) is identical expect for deleting the weird air temp compensation that prevents max boost in colder air. So with this brew you can realise more power with bigger/better IC or just good cold wintry days.
V-Stream (also in Beta) is a further development which has more aggressive boost in the upper rev ranges - really only best used where bigger/better IC is in play. AFRs not tested yet, so don't want this going too far until its been properly tested.
X-Stream - get it
- (not in Beta yet) will be a bit more aggressive again - just pushing the generic upgrade closer to limits of whats possible on a healthy car. Will almost certainly need zorst, airbox and IC upgrades to make best of this.
