The debate goes on...

[CupraTOC]

Yes, I totally agree that this topic has been discussed time and time again but where is the hard evidence?

Yes I am talking about... Air intakes.

Currently my car is standard however, I have a Milltek turbo back exhaust being fitted next week and I then plan on a stage 2 remap.

Am I really going to gain much by replacing the stock air box (Which effectively is a forced cold induction) for an aftermarket intake?
I have seen people claim 15-25 hp on the dyno by fitting various different kits compared to stock, but as discussed before, there are many variables to consider such as ambient air temp on dyno day; so the same car can be dyno'd on two different days and see a 15-25 hp difference between the two runs? So are there really any gains in real world terms or are people just chasing figures? Where is the hard evidence that these things are a noticeable improvement over stock?

I have considered two kits and if I was to buy an aftermarket intake, my two choices would be Evoms V flow or Revo street intake (Although I am still not too sure if a dry foam filter would trap the finest of fine turbo-wearing particulates?)

yes you will significantly gain..
REVO on my leon..
very good gains over its previous 'other' intake on the car before hand.

When you say gains though, is this proven and in black and white or is it by how you feel the car performs? Also these use a foam filter and out of all of the filter these are not marketed well, do they trap the finest particles that are not visible to the eye?

I can say so. My stock FL Cupra made 236bhp on the dyno. I then started using decent fuel and put a neuspeed p-flo kit on it and ran it on the dyno again. it made 260bhp, a huge 24bhp increase.

In my opinion, using Shell v-power made the most noticeable difference in my car before the remap.

I understand that it does also depend on the rollers, the climate, ambient temperatures and whether or not the planets are aligned, all of which are legitimate items to consider, but to gain as much as 24bhp is mostly down to the induction kit more than just fuel.

These proven gains you're after will be hard to come by especially if your mapping your car, not many people will map a car with a standard intake and then remap it with an aftermarket one to see if there's a difference. And most of the gains from an intake will come when mapped.

I'm no tuner by any means but I reckon you'll struggle getting decent power with a standard intake. I'm not talking number wise just more how the power is delivered. Think of it like trying to breath through a straw, swap the straw for a bigger one you'll find it easier to breath.

yes proven and measured on my dyno.
I deal in facts and data - Tune these things for a living.

Well unlike what I said.... not that hard to come across "proven gains" then .

Just buy the revo, job done

 

[CupraTOC]

So my two questions are, Will the foam filter be up to the job of catching the fine particles, although it is a three layer foam it is a dry filter with no oil.

Also if I get a stage 2 remap after having this exhaust fitted and then install the intake in the near future, would I have to flash the remap again or will the car benefit from the gains immediately?

 

[CupraTOC]

So I have fitted the Revo Street intake. It is very loud and the turbo seems to spool up quicker.. Placebo maybe? I am now getting noticeable turbo blow off when I lift off. If there is a lot of boost and I lift off, there is a loud turbo flutter that I couldn't hear before, is this normal for the ko4? I was also getting this fluttering on WOT without lifting off but since fitting the GFB DV+ this has almost stopped and it is just on lift off now. Am I going to increase turbo wear with this intake fitted?
