The problem I see from that analysis from a tuning standpoint would be that this person's testing schema is in error. I would beg to see this person's graphs under a rally condition or in drift when clutch kcking and throttle blipping are in excess. Under those conditions the spikes should be all over the board as intake air velocities are constantly at stop and go. The graphs shown are most likely as a result of a standing throttle test where an initial influx of air resulting from high air flow from the SRI causes MAF voltage to spike and once air velocities become more constant the readings become more closely matched. The stock versions fail to do this because intake velocities inside the box are dramatically lowered because of the intake air tract angles within the box and resonator. This causes the initial high velocity air to slow to a point that does not spike the MAF voltage.williaty has a write up over at NASIOC where he shows that without the resonator the air vibrates past the MAF which causes the MAF to think its getting more air than it is (AT WOT ONLY). Take a look and tell me what you think:
so basically josh when you floor it do you notice it running rich at the low end? kinda hard to tell now that i think about it...
btw someone just did a hybrid for 2008: http://forums.nasioc.com/forums/showthread.php?t=1655076
i also have a pulley its a cosmo racing onei mean its only from 1-1.8k full throttle so its short and rare... just wondering if you noticed anything. As for me im worried because ive got a lightwieght pulley which doesnt help vibration so im unsure if i should go SRI, CAI, or stock/SRI hybrid.
