Pulley/Power

I was just curious, All things considered equal, driver mod aside, no kr, decent launch ect..What would the avg quarter mile time and hp #'s be for a 3.2 pulley, and 3.3 pulley? On a Gen3 supercharger.
Thanks!
 


minimal, .1 in pulley size does not make much of a diff in power. Also completely depends on what timing you are running and other mods.
 
No, I dont mean the difference between a 3.3 and a 3.2, I am aware that it is 10hp per pulley size, What I ment was how much power (ex 280hp or low 12's) shoulda 3.2 pulley generally make? Or a 3.1 ect..maybe from people who actually run them? Maybe a sticky or something can be created.Like I said, ideal conditions, supporting mods with avg drivers and such.
 
I ran a 13.6 on a 3.4 pulley WIth high compression stock heads and valvetrain. Im on a 3.25 pulley but my trans is fubared for now. On a 3.6 pulley best time was 13.9, on a 3.8 I ran 14.1-14.2's. FWIW
 


really really really depends on all the other conditions of the motor for a power level per pulley. no one can say any of this information with any validity.
 
01Gp, Thanks for that info..Pretty Impressive numbers espc on the 3.6
Bio, True there are many factors to consider, however if enough data is collected then you can get a pretty good estimate on the gains and ET's...Thats all im Trying to do, IDK, I just thought maybe it could help those struggling with trying to decide their power goals :th_thumbsup-wink:

Mine? No they were done at a track with a altitude of 1000 FT and most of my pass's with a 2.1 60ft some in the 2.0 range. I dont worry about Da calculations
