Hello eBayers,
I have these SMALLER aftermarket S/C pulleys to produce more power for your 55k engines! DYNO PROVEN!
THIS LISTING COMES WITH ECU TUNE!
83mm = 168 crank size equivalent 40RWHP/65RWTQ with tunesSOLD OUT
77mm = 180 crank size equivalent 55RWHP/82RWTQ with tunes
74mm = 185 crank size equivalent 59RWHP/85RWTQ with tunes72mm = 190 crank size equivalent 62RWHP/90RWTQ with tunes80mm = 172 crank size equivalent 48RWHP/69RWTQ with tunesSOLD OUT
1.5 to 2 psi increase (as compared to a stock supercharger pulley)
2.5lbs (one pound less than stock 3.5) ~28.5% reduction in weight
Requires the ECU to be tuned due to differences in AFR (a lot of tuners have tuned cars with this product but will not be liable for the tune)
This is a clutch less pulley so your S/C will be engaged at all times.
Made in the USA, unlike other sellers who sell made in China products.
Here is a video of another member who simply put this on his stock E55
