You can see by my mods whats been done. I ran a datalog and got the airflow as high as 296.7 during a 0-60 run. Is this typical and what are you seeing? Thanks in advance.

 

296.9 grams per sec?

 

It just says air flow so i have no idea. It Freescan so maybe that will tell you.

 

I did look at the sheet again and it said 7 was the idle air speed.

 

Are you near sea level or high altitude (just out of curiousity)?

When I ran a mild cam with basic bolt-ons, mine read something around 280grams per second of air (this is the units used by both free scan and datamaster). I think I tuned a stockish car that made about 220 grams per second. Depending on whether or not your MAF tables have been altered during tuning, it may or may not be comparable to someone elses car.
In my opinion, if your MAF calibration is near stock, that seems like a low reading for forced induction.
I'm sorta comparing apples to oranges here but my 355 LT1 with a T70 and bigger valves in the heads has seen 400g/s...I'm ashamed to say my boost gauge is not functioning so I can't tell you exactly what boost I was running. However, I can say I THINK I have a 3-4 psi spring installed on the wastegate. I watch my AFR and as it creeps up towards 13:1 I get off the throttle so I don't blow holes in my pistons.
Have you put this car on a dyno? Has it been to a track?

 

Im around 2000 feet. I am interested if anyone with a sc unit has ran a datalog and what there max air flow was. I did notice a drop of boost pressure with the new headers but i was told that was from less restriction. Maybe there is something causing the lower numbers if they are that.
