compression?
i dont know much about the compression test on the FD but someone told me since i have blowen turbos it may effect compression?? i dont really seal how becasue compression is testing the seels in the engine but i would thought id ask. reason being is i have perfect compression in my first housing at 8.8 my secound is 6.6. i had it at mazda to fix an idel problem they did a compression test both were perfect. then a week later my turbos went and the idel was off they did a compression test again and thats when i got the 6.6 . So what all effect compression just the apex seels?
thanks alot
thanks alot

The turbos will have zero effect on a compression test. If the test was done properly, they should give you three readings per rotor. I'd ask them to do it again and to give you all the readings and the test RPM. It will give a much better idea of the health of your engine.

There could be a connection between blown turbos and a loss of compression. When your turbos failed, if bits of a compressor blade entered the engine, they might have damaged the seals, causing the subsequent loss of engine compression. Or, maybe an apex seal failed first and part of it went out to the turbos, causing them to fail.
