S3 8p - Stage 2+ intercooler required ?...

Dan bellis said:
Hi guys i'm in the same boat now choosing a fmic for me facelift s3. I cant make my mind up with either the proalloy or the airtec is there much in it, cheers

The biggest is the Proalloy but the others are close.
I would choose whichever offers you the best value unless you're looking at big turbo power in which case I can recommend the Proalloy.

The proalloy is same price as the airtec so am best going for that one. Looking at buying the neuspeed high flow pipe, discharge hose and runner flap delete kit so i'd get more from it running a bigger fmic surely, thanks alex

You would need either APR or custom software to get the RFD to run smoothly from cold.
 
Would be an idea to fit it last just before taking it back up to R-tech for another map. It basically replaces a restrictive part inside the inlet manifold freeing upto an extra 10hp on tuned engines

What does the RFD actually do?

There a set of motorised flaps in the inlet to create turbulence.

Deleting them frees up more room for airflow but also results in poor cold running characteristics which needs to be corrected for.

APR have software for this and I believe Rick at Unicorn can and obviously the ECU on mine has no trouble with it.

The car will run and start with other software but will be a bit knobbly when cold.

What was it like to fit pretty straight forward or a massive pain in the a##
 
Hi lads. Would the RFD be worth it running stage 2+?
 
Dan bellis said:
It says in the write up its a must on modified if your trying to squeeze that extra bit of power

Just wanted to confirm as most say its mainly beneficial on hybrid turbo onwards. But thanks anyway
 
On the APR website regarding the RFD it says 'This modification is recommended for APR Stage 2+ and higher modified engines'

This would be my advice......

At Stg2+ you won't get much from it in terms of bhp gains.

APR used to post up a graph or two but don't now.
This is from their US site.....

"At Stage 3 airflow levels, typical results showed a decrease in turbocharger lag, more than a 10 ft-lbs of torque gain and more than a 10 horsepower gain."
Note at Stg 3 i.e.big turbo levels,you get a princely 10bhp at peak rpm.

APR's BT kit is a GTX2867,so it does make sense to use one on the much bigger GTX3582,but I'm not sure most of us would bother trying to wring a K04 out to peak rpm,and that's from personal experience,not having a dig at Stg2+

Also forgot to say....the intake manifold needs to come off completely,and if you're undoing all of that yourself,it would be a pain.

Dont think i'll be bothering with it then tbh have you heard much about the neuspeed turbo pipes awesomegti sell Alex?

I haven't to be honest.

All the pipework on mine is completely different now,and I have a BSH intercooler to inlet manifold pipe which is fitted for WMI.
 
I have a eurojet one I will be taking off my s3 soon which is stage 2+ if you interested mate?
 
Spoke to alex earlier from aks tuning he recommends the rfd and says its well worth fitting, he has it on his own car and says it noticeable without even needing the software to map it. Also ordered a peron intercooler off him but cheers for the offer lenny

The software is not for when the car is warm and running....it's for cold starts and running.

What happens is the car will start and idle,but will not pull much load (in my case it would misfire badly above 3000rpm) until up to around 85c.
 
All he said was the car runs rough for about 10 seconds from cold then clears and runs fine. Would definately be worth setting it up right if i was to fit it. This inlet looks a nightmare to take off :wtf:

I think this is car and software specific.

Mine started easily and did not run rough

What it would not do is pull anywhere beyond 3000rpm or any sort of load until fully warm.

Be prepared for that and anything better is a bonus.
 
:racer::racer::racer::racer::racer::racer::witless::box::puke2::puke2:Fair do's. Will get the turbo pipes first i think then do rfd before getting the car mapped again to suit rather than it run like a bag for weeks

So for a revo stage 2+ just the exhaust fuel pump & REVO intake are the only upgrades you will need

I've replied to your PM.
 
RFD will also make the car laggier from what I understand. If you're happy with this then fair do's but I've been doing all I can to reduce lag. Now I have boost building from 2000rpm, much lower than a standard K04.

RFD doesn't cause lag.

What it does result in is rough cold running if not mapped properly to take it into account.
 
really couldn't tell mate as it went on the same time as the tte420 which obviously made a lot more difference. its probably a question for the tuner as i doubt the bum dyno would pick it up...

Did you notice any gains or improved drivability?

This will only make significant gains with a big turbo to be honest.
