hey guys, i just got the 9.5lb pulley installed on my s/c. was wondering if any of you guys out there have their 9.5lb pulley in combination with nst's lightweight crank, alternator, and waterpump pullies. if you do, how's it running? i know separately these things work great, but i havent noticed that many, if any, with ALL of them on their s/c'd tc's. so please chime in .

 

I have all the pulleys installed on mine. The crank pulley made a huge difference, however I noticed nothing from the water pump and alternator pulley. The alternator is a pain in the ___ if you do it after the supercharger is installed. You must lift the supercharger up or completely remove it to get the alternator out. Your other option is taking the thermostat housing off and trying to wiggle it out. With coolant at about $20 a gallon for the pink super long life I was not about to do that.

 

thanks for the input! yeah i thought the crank pulley would help the most. if it's alot of trouble for the other two, i might just not do those. anybody else?

 

To bring this thread back from the dead... would having the lightweight crank & NST 9.5lb pulley need to be tuned or is the TRD s/c ECU flash enough?

BTW i am automatic

 

yeah, the stock trd tune is fine with the 9.5 psi pulley.

 

Yeah I have both and im Ok with it

 

does anybody happen to also know the gains with this combo? I am looking to unlock more power out of the car.

 

^ going from 7lbs to 9.5 and the crank pulley should give you about 25whp and 25trq
