Well today was awesome, went to Ride Revolutions in Johnson City TN for a dyno day, sorta depressed with my N/A number I was running 125 WHP but that is with an auto and plus I was running rich. Though with my 50 wet shot I pushed 170 hp was not able to get a torque reading because the place could not find my tach signal oh well. Looking at some of the other nitrous numbers for a 50 shot for an auto I am impressed with mine, it was an awesome day. Though I do have a question is it normal for a 2.2 ecotec to run rich N/A?

Yes it's normal to run rich n/a...I just don't know how rich though.

ah i was happy with the numbers i've heard of 2.2 ecotecs with a 55 wet zex shot 5spd only pushing 158 hp so i'm pleased forgot to mention that wasnoly with 850 bottle pressure.

an safc II could correct the running rich right NJ?

Sounds like an Ln2 number


N2O + Bolt-ons = 220Hp/250Tq

I thought the eco ecu was always trying to get an A/F of 14.7 especially since his cav is post-03? 14.7 is hardly rich no ?



15.574 @ 89 mph stock

at idle my 02 eco ran 14.7:1 and once the dyno started at 47 mph i was 12.2 and the lowest it got was 10.7 from 102.8-104.9 mph... so yes rich is normal

and the place i went to had a wire they wraped around one of my injector harnesses to get the tach signal....

also i ran 133.4 hp and 150.4 tq on my run....
