    suitable boost on s3

    is 1.7bar suitable for an s3 8l with cai, green cotton panel, agu head with transition gasket, 3" pipe straight thru, relentless mani, all silicone hoses under hood, fmic, custom map, turbosmart dv, debaffled charge pipe? my tuner says these engines are capable of running this boost. ive read 1.5bar is max though.
    any advice appreciated
    thanks in advance

    higher than I map them to on std internals...
    that level of boost is heat generating.

    what boost pressure would be safe to run on this setup?
    could this also trigger an overboost code?

    if mapped properly there should be no codes..

    are you experiencing issues? asking after the map is a bit odd.

    Not everyone tunes the same way.. Your custom mapper did what he did... and you paid him for his services.

    as for "safe" level.... haha... is there such a thing.. kinda like pin the tail on the donkey

    its not just boost which determins the power/safety of the tune.. Commenting further is futile without data to see.

    that sounds like a fairly decent st2 spec, but at 1.7 bar, that's 25psi, I'd be concerned about the stock rods myself....

    Also, I'd be concerned about why it's mapped to run that much boost? Developments in mapping over the past 2 years or so have shown that to get the best figures from a ko4 you need to keep it down to below 1.5 bar and make the power from the timing.

    if they had boost at 1.7, I'd ask a load of other questions on all the other parameters they changed, including timing.

    sounds crap if I'm honest mate Sorry for being plunt.....

    Westy has 305bhp from the same boost, granted that's with WMI and a built engine, but it gives you an idea.

    Plenty of cars have made 290bhp at both R-tech and B5 from 1.5 bar....

    Sounds like old school tuning methods being employed here....
