What lb/min are you flowing on pump & bigger turbos

[blcknspo0ln]

Just adding:

47 lb/min @ 24.5 psi (via dsmlink GM 3bar) falling to 21.8 psi by 8k on 93 pump. My average airflow is usually 44-45 lb/min (boostleaks? temperature?)
50 trim, 2.0L 8.3:1 comp, best 1.95 70-90 time

[daren_p]

My update would be 42 lb/min at 24psi on pump w/meth. See this flow by 6400-6500 rpms, where my airflow flatlines. That's on the crappy 2g intake mani, soon to be replaced with evoIII intake mani, which should help the top end flow numbers.

Seeing an honest* 47lb-min on 25-26psi on my GT35R + pump and windex-injection

*My earlier 50-trim 49-50lb-min airflow readings were likely skewed upwards a few lb-min as my air intake pipe protruded a bit into the coupler that connected it to my MAS which (I believe) focused more air thru the central metering area thereby inflating the reading.

Nice. If I may ask, what are you running for peak timing? Also, what do you have your a/f's tuned at for the pump gas?

Congrats!

Here is an update for me since the recent mods (Ported O2 sensor housing & Exhaust Manifold, DSMLink, 3" catback & Meth Injection). Keep in mind this is an untuned, EVO III 16g @ 21psi, AFR of 10:1 on the stock SMIC.

^^^ Is that a 30.9 or a 36.9?

Thats some nice airflow you are getting with the stock SMIC! It looks like you are seeing 36.9 lbs/min. The meth injection option is looking pretty tempting to me, since I am one of the few DSMer's still using the stock intercooler.

If you have DSMLink, post a log...

It's 36.9lbs/min. I couldn't get the darn picture to conform to the site requirements and retain the clairity. I guess I should have used a thumbnail.

It's posted up on the DSMLink forums if you want to take a look. Here is the link to the thread.

15* peak timing [brutal, it plateau'd at 6k], a little knock on top of 3rd; my aem uego says I was running 11.6 afr but I think it's incorrect; projected a/f was at 10.8 across the rpm range.

Time for meth injection

[90blacktsiawd]

New set up is in so it's time to report in again

2.3l
unhacked 2g mas
ported 2g head w/ 1mm OS valves
cyclone that is running all 8 runners all the time right now
272's
3076r

52.7 lbs/min @ 24 psi. It was about 35 degrees out as well.

[danyz250f]

50 lbs/min not very good tune but calibrated maft with dsmlink and pte 6031 (60-1)

daily 41 lbs/min on ~17psi~

I wanted 50 now I want 60. The sickness gets worse....

Isnt a good horsepower calculation times your lbs/min by 9 and that gives a close hp number?

[RipperXX]

I did find a boost leak, and was and still am pretty much uncalibrated. Soo yea my air flow #'s were most likely a little off.

I got tired of trying to get the LTFT and STFT close and gave up. Made a small correction and left it alone. I need someone to tune my car for me .
