Re: supercharger pulley vs. crank pulley
We have the rolling start down to the point of where its not an issue. Whoever hits it first gets off and back on the throttle for a millisecond to keep it even. It doesnt even matter if he starts first the 181 car pulls on the code 3 car instantaneously. Once again when i had a code 3 we were dead even. Thats as technical as im gonna get with that.
Here is the data log in 54 degree weather with the 181 pulley, NW intake, IM tune, and supercooler. The line on the first screen shot is at the top of 3rd gear, the line on the second is at the top of 4th. Notice the AFR starts to act up in the top of 4th gear, and it directly corresponds with the messy fuel reading. This car has a walbro 255 FP.
A word on the blips in the lines. The AFR highs are 19.5 AFR and lows are 13.2. The fuel pressure highs are 65psi and lows are 48. Thats one hell of a fluctuation. Have fun with this.
