3K at about 62 mph? Sweet--With the s2 trans and the 4:44 diff in 6th gear I am at about 70 mph (112 kph)at 3.2K rpms.
How many miles of break in are you going to do before you do a little "testing" lol.

the pan needs a vacuum source to help pull out all the vapors etc. If you just vent it then things tend to accumulate. the oem vent system has to many twists and turns in it etc to work properly.
thats mho anyway.

What kind of radiator cap are you using Brett?
320grams? On oem calibration?
Nice.

yeah I dont vent either, I plumb back in after the catch can. Most will say this is a preference thing but I agree with denny.

you mean this hose? (Edit: Maybe your question is not posed correctly since it is vented back into the intake)

I love your accordion hose from your diverter valve.... You dont have any issues with the MAF set up? Seems awfully close to a bend.

None at all - maf readings are more stable than most i've seen .


With regard to the oil vent tube - I have run it vented straight to atmosphere before without issue .....until I started getting some blowby . Then I found the escaping air was affecting the tune as it had initially gone past the maf so was effectively unmetered air. Since finding that out I now prefer to run it into the intake even though I don't like contaminating my intake with oily air . Lesser of two evils.

your graph is g/s and rpm vs time, not g/s vs rpm

/\ nit picker !

The interesting thing about the log is not the mislabelling . It's that it was done at a constant boost - yet flow seems to improve as rpms get higher . Don't think I have seen that before.

Compare with below from previous setup ..... at slightly higher boost levels . Quoted from previous thread "Boost is currently 7.5psi up to about 6000rpm then tapering down to 5.1psi at 8250rpm"

not nitpicking if you want to see it accurately

you need to open the APV much earlier

Good point

log was done in 2nd - APV will open a few hundred rpm earlier in 3rd so will see what a 3rd gear log looks like before touching it .

think in 1000 increments, not 100s

this is a turbo, you are forcing air in, NA flow dynamics are out the window
