I just got a pocketlogger about a week ago. I have been doing some datalogging. I have seen a maximum air flow rate of 34.56 lbs/min. I was wondering what other people have seen. If you have some data post it. If not, go datalog a 3rd gear run to redine at 19 to 21 psi of boost and see what kind of numbers you get. Lets see how much air the little stock turbo will flow.

No luck this weekend? I'm far from stock - otherwise we could meet up and do a baseline on my car. Maybe try the regional forum for a local guy who is willing to make a run with an unmodified car.

I already Datalogged Tims stock ECU car with HKS intake and Blitz catback. I didn't pull any air flow (MAF) numbers. I did some on mine. I am trying to find out what other people are getting as far as maximum air flow numbers when datalogging. My friend with a 20G DSM on race gas at 25 psi sees about 39 lbs/min. I am trying to see what other people are flowing with the stock Evo turbos.

I have an Evo III 16G on my Eclipse GSX. I see around 41lbs/min at 22 to 23psi. I see 44lbs/min peak at 26psi.

26psi ran my 3315lb car to 118mph 1/4mi.

I am datalogging with DSMLink, though, not Pocketlogger.

Also, you have to make sure that the MAF isn't hacked on the cars you are getting these readings from. Any change to the MAF will throw off the readings.

Oh, and if the car has an AFC or an XEDE or any other piggyback, you also can't trust the readings since those boxes are designed to change the MAF signal. I can't imagine tuning without knowing the actual lb/min flowing through the engine. One more reason to hate piggybacks.

 

3"TB; buschur cone filter; dynoflash; see about 31-32lbs/min

 

SuperchargedGTX: What boost pressure are you running to get that airflow reading, and at what RPM did you achieve it?
