What Air filter are you running with what BHP. CUPRA

Just round the corner.
I've got the Forge twin take on mine, but have found a few rubbing issues. But the trade off for the noise is worth it.
Blufin stage 1, running qpprox 300 bhp.........For now!

I believe cars are getting around 300BHP with just a remap stage 1 and nothing else. This is why i think that you only need the extra air flow at certain stages of tune, which is why i think the pflow may be good enough up to a certain stage and then it becomes the restriction.

You also have to consider the position of the MAF in the intake pipe for these figres. A dbilas for example sits off centre and as a result shows low figures as the mass of air (centre of the air feed) doesnt pass the sensor.

What you can't dispute however is that the fastest 2.0T cars mostly run EVOMS intake. That may be because the EVOMS was available sooner and more money spent on those cars, or it could be that those cars also had secondary air feeds etc etc.

As an example, mine ran to almost 116mph teminal speed on the 1/4 mile with an Evoms and S2+. Closest Leon Cupra I have seen to that was RobH at 114 (I think) and I am sure he runs an Evoms too.

Nar, Rob runs an ITG Al.

For what its worth, I don't think you can read too much into Mass Airflow Figures especially between one brand to the other, Maf placement in the intake piping plays a mayor part to readings.

I'd be careful of the neuspeeds pipework that mounts to the engine block, looks exactly like the BSH Truseal and H8T WP managed to break his mounting lug off.

Iv'e read somewhere that Maf Scalings can have a knock on effect to Long Term Fuel Trims (logged on Block 032 on VCDS) so if the Maf Tube isn't correctly sized the trims maybe affected.

Of course, this is my own personal view and opinion, based on personal findings and what can be found and read across the web.

.

I've read that somewhere too somthing to watch out for might be worth adding rubber washers to absorb movement, the p-flo on one side has plastic/rubber bracket, I don't know how much that helps to absorb shock.

I always thought that the Fuel Pump was one of the problem factors when you upgrade the air intake?

The fuel pump is a big factor with these cars and is needed for stage 2+ but all i am asking is if this was changed would a pflow be able to supply enough air or would we need the itg or evom set up.

what is the mounting lug used for, does it hold anything else. I guess the evoms and ITG do not use this lug

Fuel pump is only a factor when going to stage 2+ as stage 2+ requests more fuel/pressure than the oem pump can deliver. I hope I'm right lol

And as K1Shane pointed out, I'm running a p-flo filter and works fine on my car, I keep up with alot of higher powered cars and the filter doesn't seem to hinder my cars performance in anyway :) Revo said it's one of the top filters for the 2.0TFSI but at half the cost of most others

The ITG uses the same lug and is supplied with a plastic spacer, plus having more Silicon hosing with it, it has quite a bit of flex. So, hopefully the lug shouldn't get broken off.

They are all "filters on sticks" I'm sure if you fitted a Neuspeed then you will have no problems at all and a bit of money left in your pocket ;)

i was thinking the same Rob but more along the lines CDA BMC enclosed filter with air feed. would make it a proper CAI then i guess


lee

i work for a company who use a product called armaflex which is a insulating foam product , i could make a stand alone air box from this material quite easily , togehter with using thermocouples i will be abale to gauge heat spots and cool areas , i think i will do this over the next couple of weeks , it will be a lightweight solution and will also let me play around with shutting off certain breather areas and maybe exposing others.

will that be cheap to make and can you make more than one :)

Lee

cost wise yeah pretty cheap i would imagine under £20 , once the sizes are known its only a matter of gluing the pieces together and the glue used last for ages !
so will basically be like a liner that you air filter sits into in the space by the battery would weigh next to bugger all.

im not sure how much airflow comes up the inside of the wing and into the space by the battery?

brad1, have you had your car on the rollers as this would give a good indication of the power available on a stage 2+ with a pflow.

And NO i am not going to pay to have your car RR. LOL.

Cheers

I thought you need the hpfp, for stage 2??? I've got my Milltek down pipe to put on, then got to get the hpfp then I'm going stage 2.

Fuel pump upgrade can be needed on some remapped cars where boost is high, especially with an updated air intake.

What happens is the standard fuel pump cannot supply enough fuel at the higher pressure and the supplied fuel pressure will drop (channel 230 in vagcom) causing the ECU to retard things to maintain engine integrity. This will effectively slow the car down among other things like potentially causing engine damage through running too lean. Several cars have seen limp mode/cut outs due to fuel starvation.

An air intake on a mapped 2.0t gives a healthy power increase for sure but you need to ensure the base is there to sustain it and with that in mind, I would look to upgrade the fuel pump sooner rather than later if tuning a 2.0t. At the very least i would log it regularly enough to make sure fuelling, timing etc is all ok.
