LCR Airflow readings

[bentaw]

what sort of g/s should i be seeing with a Revo'd Lcr and a standard airbox not smoothed yet

 

[Si]

I see 195 - 205g/s depending one weather conditions.

 

[bentaw]

i am seeing 173

 

[Ruddmeister]

i am seeing 173

Have seen just over 200g/s, average is as Si said 195ish

MAF quite often fails by under reading rather than going completely dead, any chance you can borrow one from a mate? if not GSF have them on exchange for crica £85 ish

i have 2 actually funnily enough after a mate descreened my orginal then i had all the boost problems so i replaced the maf then but kept the descreened one perhaps i should try putting that back on

in the height of summer i got 197, in winter i got 207 (thats on modified airbox, not open cone!)

bentaw... wats ur maff read on tick over when your car is at temp... ie. at 750rpm ???

i think a healthy LCR maff should be about 2.8/2.9g/s

 

[bentaw]

i will have a look in a bit and see what it is

 

[Si]

I see 2.86 at Idle

Take a sneak peak on this site, you'll find a thumb rule there.

Also, idle readings aren't very meaningful so if you are unsure always do a ful throttle run. Besides that, make sure you've got a solid reading without jumps and such thing - to achieve this make sure to have a high sample rate while logging.

my car never actually sat at idle it fluctuated between 2.56g/s and 2.86g/s and on the odd occasion it hit 3.1g/s the rpm never sat still for more than couple of seconds it was just bouncing between 720rpm and 760rpm. This was all at idle never touched the peddle once

Mine reads anywhere between 2.6 and 3.1 but it idles at 720rpm constant.

As for peak flow, Mines APR'd not Revo, but it peaks at 190g/s with the dynatwist on and gives similar figures with the standard airbox although not as strong throughout
