You don’t need to spend £1400 on an IE intake for 500hp. I’ve been tempted too, mainly for the carbon look but didn’t need it.
A Forge turbo inlet pipe, larger back pipe & a K&N filter is all that I’ve had fitted on the inlet side. The first two only added 25hp with no peak torque improvement. Not that I regret doing them for a second as it was a very cheap 25hp.
Here is a before and after fitting of the turbo inlet & back pipe. For the sake of clarity I don’t have a TT-RS, that’s just what comes up on Dave’s dyno.

Need to decide if I want to mess with the opf nonsense haha
We're you on SNet Banny as I recognise the username?Nah I still love imprezas and its good to reminisce with a fellow ex owner, thats an clean engine bay looks like an RCM build?

TX.
Edit - remap only will get you close to 500/500 in a FL.

Unitronic have a similar intake to the IE version in development which must soon be ready for market. I believe MRC may be able to source one?
These 4 inch expensive carbon intakes seem to work best when running hybrid/big turbo conversions where the benefits of the extra airflow can be fully utilised.
I run the Forge larger air intake and larger silicone turbo inlet (only thing currently available for RHD cars) BMC hi-flow panel filter with MRC switchable mapping. Results is around 550ps (seen as high as 560ps on different dynos) and up to 767nm. This is stock turbo.
There's some good design tweaks on Uni, like the flexi-pipe design and reinforced clamping sections. No doubt they'll have it flowing at least as well too, it's been a long time in the design phase, not much said about it of late but I believe they are in Production now. I am intrigued to see a comparison.
IE did have data showing at stage2 their intake has quite a good ram-air effect which is where they said it will start to see good gains. Those with higher DA will benefit earlier I guess, I took some grief for showing my data on FB with no performance advantage at stg1 but others did in more extreme conditions. Point I was making is that it's not as simple as 'which is better', and those buying should be aware it may not be necessary depending on their requirements and atmospheric conditions.
Those are great figures, I'm not sure there is much more to be gained on the stock turbo without exotic fuels.
I have resisted the E85 route despite the temptation of the bigger numbers.......too much hassle here in the UK
I can attest to that, I ran various blends and ended up with a US 5-gal jerry can secured in the boot! It was fun while it lasted but not practical over here, 2-stage fuel stop got old and range hit by 1/3 on the E65 equivalent blend I finalised on. I'd be comfortable taking a couple of jerry cans to Santa Pod or something of the sorts, and will def flip it and fill E85 when driving in France. The Unitronic isn't quite as simple as the MRC switch though, need the tablet and cable every time.
I'd be interested to know what positive results you found with Octane booster - I only have maps for 98, 108 and E85 and timing logs are clean, although I swear the tank of 99 with 1-2 gallons of residual E65 went a bit better, need to do more logs some time.
Sounds like you found Stage2 worth it as well - going Stage1 was the biggest performance increase, stage 2 still significant (.7s off 100-200) and made driving much more of an occasion for me with the noise, extra revs and relentless top-end.
Yes, for those of us looking to mod at some point it's interesting discussions.please post away It is interesting stuff
I had my heart set on the new APR open cone filter but it doesn't fit RHD cars apparently. Do we know what the issue is and if it's fixable?
is it not due to the brake booster being in the way on the RHD cars?
