Verdict - Airflow

[P10 GGOT]

Hello,

Just after peoples opinion really.
I've currently got a completely standard (or so i th ought) 03 LCR, and yesterday I decided to fit 007p and smooth/ drill airbox. Fitted 007 and found out that it already had an open filter fitted all be it in a home made and very OEM looking casing. Anyway took casing off and after sounding like Darth Vader on Steroids is thought I'd run some logs through VAG COM

Turns out, mass air flow peaked at 171.11 which i work out to roughly be 222BHP?

I've got to be happy with that right, considering its meant to be 210. thats despite the fact it need a service.

Pic's & log to follow, let me know what you think as I'm new to forced induction

Cone filter inside the OEM box ?

Why bother with the box?

Probably though it would help with heat soak, better off with a panel filter though.

 

[Ruddmeister]

Heatsoak was always a 'concern' you're right, never seen any occurances though........always wondered if it was a 'real world' issue or just a theory ..........plus the last three summers in the Uk the heat has never been a factor

The key to decent induction was always in how to get a decent airfeed in round the battery.......without relocating the battery it's not a simple solution.....infact even relocating the battery it's tricky.....not sure I ever got a 'good' result in the 3 or 4 solutions I tried

The open filter wasnt in the OEM box, but had had a custom (cylinder) one made and was in that. bolted where OEM box once was. I looked very neat, and wasn't obvious at all

You got any pics of the filter and box that was on there?

I'd be interested to see original one to

does the diy cover have a cold air feed goint to the inside of it, or an open end? looks very restrictive on airflow to me, no real air feed to the actual filter inside is visible.

 

[P10 GGOT]

It was using the OEM feed to the box, however I removed that when I removed the housing.
TBH it pulled well with the housing on, but it's even better now
I may put it back on and run some logs see if the housing has any effect

 

[adam cupra 20vt]

That looks like some kind of Viper kit but without the air feed pipe?

Looks like a paint tin/coffee tin sprayed to me.

Nope, its wood.
About 12mm thick MDF at base with a thin sheet wrapped around it. Silver foil and bubble wrap stuck to inside, guessing as some sort of heat shield. Then plastic ring on front .

Pics don't do it justice for what it is and it does look OEMand that it should be there when fitted

I "wooden"'t have thought that!

I bought a small LCD display a few weeks ago with temp sensor which I'm planning to setup in the car.
Going to put the thermister close to my open cone and put the LCD display at the bottom of my pillar.
Be interesting to see how much the temperature changes inside the engine bay when moving and when stationary in traffic. Obviously temps are going to rise when still but I'm thinking they could drop back down to ambient temp quite quickly.

Also been thinking about modifing the ducting for the side mount intercoolers (I have forge FMIC) to use as a big air scope and feed to the filter

 

[LEE69]

I did that test years ago, you'll be surprised at the results.

 

[jonathanp]

I'm curious now, how did your tests turn out?
