Anyone know or have a dyno with a/f info with differant size pulleys?

Like if the a/f is 11.2 with a 2 Ib lower what would it be with a 4Ib lower or even a 6. With the same chip program

 

James,

Check the dyno charts that I sent you...they should show the A/F's when I went from my 4 lb. lower to the 4 lb. lower and upper...didn't reburn chip in between.

I was told by a reputable tuner that about .3 for every 2lbs of boost

so if you were 11.3 stock you would be around 11.6 with 2lber and 11.9 with 4lber you wanna keep it at 12.0 or under i believe.

For the record,I have yet to hear of even 1 problem running up to 4lbs of boost without chip.

 

Thanks guys

 

My truck dynoed with a 12.0 A/F Ratio stock. I dynoed it with a 5lb pulley and a 12"cone air cleaner (no chip) after I had driven it around for a couple of days. The A/F Ratio was 12.0
