You have done many test, thanks for sharing it

I will test my bosch one reverse

I use a similar recirculated bov like this: Today I got the idea to take it out, and guess what it was my problem :D So at some boost it starts to open a little bit it is recirculated so the air stays in the system Thanks for all your comments :) Which side in the photo, it will see pressure (excep...

Did you try adjust to more spring load on the HKS actuator ? => The setting at the boost controller where at the max. full set and gain The way you adjust the set and the gain to the max, it is almost leak away all the pressure to the actuator, if you tried disconnecting actuator vacuum hose still ...

I am not able to achieve more boost then 1,25-1,3 bar and I don’t know why -> I have done a pressure test to check the piping and all hoses are leak proof with 2,0 bar. how you did pressure test? a lot of people doing it wrong. Best way to do that is: remove MAF and put z32 fuel filter into maf pla...

anybody else a new idea? how your intake looks like? air filter can do something like this: https://www.youtube.com/watch?v=fwLySsnNXU0&feature=share stock intake hose also can do the same I am using a modifided stock airbox, with a K&N replacement filter http://www.porscheshop.co.uk/acatal...

1. try disconnecting actuator vacuum and run in 4th or 5th gear (the things going slower) and see if boost goes over 1,3 tried it today, max. 1.3 bar => I checked my pcv valve it, it does not close well in direction valve cover. I ordered a new one. Could this small issue make such a big problem? W...

Garrett 3071r with 0,64 AR @ SR20DET

you have to port the exhaust housing, then it will work, done at a mates car+ forge actuator

Garrett 2871r with 0,64 AR @ CA18DET
the 56trim version works well, good boost controll, also with stock manifold

1. try disconnecting actuator vacuum and run in 4th or 5th gear (the things going slower) and see if boost goes over 1,3 2. are you sure that exhaust gaskets are not blown? especially manifold-turbo 2. gaskets are fine. manifold-turbo checked about 500km ago (exhaust housing was changenged to 0,86ar)

I am not able to achieve more boost then 1,25-1,3 bar and I don’t know why -> I have done a pressure test to check the piping and all hoses are leak proof with 2,0 bar. -> I have tested a OEM actuator same result -> I have testes a new HKS actuator same result -> I have tried the boost controller AV...

We are talking about the same, I am using a knock analyser: You can adjust the frequency band and the sensibility. The knock analyser gives you then values between 0-95 It is adjusted that values from 30-45 are ok A value of 60 is my personal limit If you get a value from 95 it means knock (you hea...

Knock monitoring I do all the time If I lean it knock values will increase I wouldnt call it "knock value". Its more like increased engine sound, but it doesnt mean its knock. You have to find where is knock and where is just increased sound because of more pressure in cylinder (more powe...

From what ive seen on different maps, timing is supposed to stop increasing when you reach peak torque and remain constant. Otherwise you end up with overly retarded timing, and high EGTs. In my case, my map starts off in the single digits under low rpm/full boost, and slowly increases to 18* @ pea...

If I drive at the racetrack with 30 degree Celius (ambient temperature) my EGT goes up to 1000°C, after a few laps I have to drive piano, otherwise the EGT rise more under full load With 22 degree Celius (ambient temperature) there is no issue with the EGT, about 950°C peak, pedal to metal for 30 mi...
