    Hi Guys

    I know 90% of the forum is S3 but there are a few of us TDi guys here.

    im squeezing more oomph out of my old 110 VE (non PD) engined TDi.
    seem to have hit a wall now as the inlet pipes can't do any more flow.

    Can a 130 asz engined A3 owner plese remove their Air flow meter and measure each end and let me know as
    i have been told the 130 items are larger bore than my 110 items.

    I have the full tdi 150 Golf Turbo and full exhaust from GTTDi 150 ARL
    but only the ARL Tip and i think the Airbox lid and AFM are strangling it :(

    Pipe size is less of an issue on turbo charged engines than it is on a NA... while bigger pipes are always a better idea its not always as simple as swapping pipes over..

    You mention taking the MAF off... are you considering changing the MAF to a larger one too? if so this will need to be scaled in the map...

    Most of the cars on here are 1.8t rather than S3... not many soot chuckers about granted... :)

    Why not fabricate hoses using alloy bends and silicon joiners etc? thats the route most people take when doing this kinda work and you can then make it the size you want...

    Hi Tufty

    Good info mate.

    I'm still getting to grips with twiddling my map
    you think it will be easy to rescale for the larger MAF ?
    i noted that a lot of the big power tdi's do away with it and run Maf less
    but i prefer to do my own maps so thats out until i get more clued up. ;)
