This is the kind of "bolt-on" performance a lot of us are looking for.

One question though, if I already have my car tuned by Tune-Tyme, would they need to re-tune after installation??

 

no, your not really letiing it breath or adding more a/f so you should be just fine

 

well i just got finished installing my stock size lightened crank pulley. you can def tell a difference. with no load, the motor does rev quicker. my buddy and i both did a before and after drive n could tell n improvement. now i just need to compliment it with the alt. pulley.

 

Yeah.....I need these......

 

late night there, ssfamilywagon? lol, i remember those nights!




my input on the issue at hand, for the record, ANY weight you take off the engine will make it free up horsepower. 3-4 pounds less of a crank pulley may be sitting still, but what is that 3-4 pounds at higher rpms?

simple example, why do people get lighter wheels/tires? apart from probably being stronger than stock ones, they take off a tremendous amount of
rotational mass. less rotational mass means less load on the engine. less load on the engine means freed up horsepower

another example? take off your a/c compressor and get another belt to compensate for not having one. no a/c compressor = less parts to move = less rotational mass = freeing up more horsepower

Like enOonmaI said, magazines have been proving it for years. look it up instead of doubting it just to doubt it

 

Hi-especially SSFamily Wagon:
How hard was it to get the old pulley off and new one on? Did you need a lift? Where did you get it? I want desparatly to be the next one here to do the pulleys

 

i got the pullies,intake (which i listen to nobull about getting airaid not cgs) short shifter, axel back dual exhaust and thats it but please guys remeber there is so much more you can do..header/down pipe/ upgrade your injectors with the proper tune/ port and polish your heads/ you can upgrade your springs/retainers and raise your red line.........these little engines can

 

I'm not in the production stage yet. Just prototypes. I'm having 50-75 alternator pulleys made soon...when I do I'll probably sell them on ebay and j-body.org, and become a supporting vendor here. But I only have a few prototypes as of right now.
Heres some pics from my last group purchase on j-body.

 

actually it was really easy to change the pulley. i didn't use a lift at all. you just need a floor jack and jack stand. on my car i had to remove the intake to give me room to swing the tool for the belt ten. just removed my pass front tire and loosened the front portion of my wheel well. one bolt holds the pulley on. used my impact for that, and then you could just literally pull it off wit your hands.

 

Most crank pulleys will require a pulley puller...it shouldn't just slide off "that" easy.
