Re: Code3 Pulley size question
Just for comparison
I ran a 181 till I had a problem with it. No boost gauge at that time.
The stock boost I had was about 14, see my dyno runs in the gallery for backup.
With the code 3 and CAI, I was up to 17 PSI and gained less that 10 HP at the 6000 RPM point. When I added the second CAI inlet I got 18 PSI with a 35 HP GAIN AT THE BOTTOM END, BELOW 2500 RPM. Code three does its work more at the bottom end and is less impressive at the top. The overall response is good without buzzing the pulleys and accessory drives at an over speed rate.
Now with a 178 I am hitting 20 PSI and lean out above 18 PSI.
This is WITH THE DUAL CAI infront of the radiator which eliminated the intake restriction giving me 1 PSI more boost for that change alone.
With the 178 and code 3, I was going about 24 PSI with total loss of torque NOT DUE TO HEATING BUT DUE TO LEAN OUT( I have a 4x bigger H/E than stock with about 3x the flow, but the data logger was hitting its limit of 17 to 1 F/A ratio. I pulled that off the street the same day, too too much FOR NOW.
Now that I have gotten the data for various setups, I am about the fuel mixture problem and at this time DO NOT believe that a tune is the issue.. Guess that makes me a mad dog or Englishman in the midday sun for the breakaway thinking, but you all know me for that...... Thinking out of the box, when I get it going Ill let you know.
Woody. PSI code 3 is easier to install for the mechanically - tool limited driver.
A few charts for comparison one CAI and two CAIs
