A/F reading

[jnoplay]

I'm running a rx-1 front mount turbo and woundering what i should be seeing for A/F readings at idle, 1/4 throttle, 1/2 throttle, and 3/4 to full throttle. I am also running meth on 87 octane and 15 lbs. of boost. Oh and im at 1000 ft. above sea level.

I set mine up to run 13-1 @ Idle, 12-1 at any cruising speed, and 11.5 @ WOT. I do not run Meth and don't know how that would effect A/F numbers. I would check in with Hurricane, dave. He would get you set up good. Or Ted Jannetty, those guys run at the same altitude as you and would know more on how to help you with jetting and such.

87octane???!!!! Is that all you can get? 87,Meth and 15PSI. I think you are pushing it big time!!! Stock CR?

No i'm not at stock CR. I installed a .060 head gasket in it. I bought the meth kit from hurricane and dave told me it would be fine on 87. I just forgot to ask about the a/f.

You will make safe power on meth at 12.5 to 1 AF.The Apex and RX1's should run at 11.8 to 12 without meth but the af should lean up a bit with meth

Cool yea i did not know you dropped the cr. Good luck!!!

so i need to be at 12.5 for wot but what should it read at any other throttle. Just wanting to know so i can watch it and not get worried about melting down my motor.

 

[HURRICANE]

13.5 idle
12.9 light load
12.5 rest of the time

Thanks a bunch!!!!

These numbers, are they for a sled with meth, or? I have an '03 rx1, front mount with head shim running at 15pounds..... is 12.5 too high without meth, or is 12-12.3 a safer range to be in riding around 3500 to 7500 feet on 105 ocatne fuel?

Those #'s are for with meth.If you are not running meth then your AF should be from 11.5 to 12 at WOT
