Following on from my other thread i have decided to make my own boost leak tester like this one:
http://www.ebay.co.uk/itm/AUDI-S4-RS4-TURBO-BOOST-LEAK-INTAKE-PRESSURE-TESTER-/160964535126?pt=UK_CarsParts_Vehicles_CarParts_SM& hash=item257a3be356&clk_rvr_id=451324834733&afsrc= 1
But I've got a few questions that I'm finding mixed answers for when googleing.
1. Where do you attach the tester and where do you block off?
I've read that you can either take the air filter off and put the tester in its place. but this can blow seals on the turbo. or you block off where the filter goes and fit the tester to where the n75 goes but I'm guessing that would also blow the seals.
The other method I've read is to use the hose that's fitted to the throttle body?
2. What diameter hoses will i need for the tester and the budge ?
3. What PSI should i pressurise it to ?
