Hello eBayers,
I have these SMALLER aftermarket S/C pulleys to produce more power for your 55k engines! DYNO PROVEN!
83mm = 168 crank size equivalent 40RWHP/65RWTQ with tunes
77mm = 180 crank size equivalent 55RWHP/82RWTQ with tunes SOLD OUT
80mm = 175 crank size equivalent 48RWHP/73RWTQ with tunes SOLD 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.
