my airflow seems a bit low...

[Tra2xx]

So I was doing some 18g-ing and did some datalogging, but I noticed my flow numbers seemed to be somewhat low??

I'm getting 1607hz peak at 4300rpm and on... At the time I was running 17.5psi on colorado's sweet :rolleyes: 91 octane pump gas

Knock counts were around 9, o2s around .94 (way rich), and timing was from 14-20, usually around 18.

I just thought I would be getting more airflow out of it at that boost level - considering people at sea level have been known to get 1600 from t-25s on 18psi.

I also have a boost leak, which may present a problem.

Any thoughts?

Fix the boost leak - THEN tune. Until thats fixed youre going to have a helluva time trying to tune.

I agree, fix the boost leak then let us know what it looks like.

Is that 1606 Hz on the S-afc? Or a logger?

The ecu/logger will only read up to 1606 Hz, the S-afc shows the real deal.

That 91 pump gas at Conoco is plenty good for easy 12's up there. ;) Full 1g street weight even!

But then again it's only an 18g... :p

Alright Van, that seems to be my answer :)
I was looking at my logger.

Anyways, the boost leak will be fixed tomorrow (no I wasnt going to tune with a leak, I was just seeing how the car was) because there is a boost leak get together.

Van - it is a small turbo but I settled with it due to reading your dislikes about it/experiences with the mutt on DSMtalk.

Plus I want some more experience under my belt, as much as I honestly do trust my driving skills the thought of messing up because I didn't have enough experience to handle a lot more power is not something I want to actually face.

As far as this 91 octane, bleh. My pea shooter would prefer some serious octane for it to even think about 12s... :) :) :D
