Being that the a/c compressor mounts with 1 bolt to the bottom of the fan pulley mounting hardware i decided i had to cut the fan pulley mount so i could still maintain strength thru the fan mount ( for the pulley) i shaved it down so it would't rub by going from the top pulley down to the a/c pulley (which bypasses the fan pulley and idler) Believe me this fan definatly has a LOT OF restriction on the motor, the pulleys weigh in around 2lbs combined and you can try to spin it but the pulley for the fan won't even spin 1/2 turn without stopping from restriction, so thier is without a doubt a gain of 5hp just by bypassing that IMO.. This is why I probably didnt see any gains from removing the stock fans and going to the electric fans cause we havent bypassed the idler and the restrictive fan pulley.. I plan to get this re-dynoed in arlington when i return to see what gains i got from removing those 2 pulleys for everyday driving..
As for the track pulley I can't bypass the powersteering cause i'd have to have the teeth ( or grooved part) of the pulley facing the tensioner which would be bad, it is supposed to have the flat part of the belt against it, so bypassing the power steering can't be accomplished unless a idler is put in on the right side of the motor (which imo wouldnt be worth it) But i was able to bypass the a/c compressor, fan pulley, and the idler pulley on the left side of the motor, im hoping this shows some good gains for 4-5 hrs of frustration,lol
will letcha know how she does at the track if it stops raining this weekend :/
The street pulley goes from 8 to 5
The track pulley goes from 8 to 4
