Light Weight Pulleys
Does anyone here have experience with RALCO RZ light weight pulleys?
They say they get the same amount of HP as UR Pulleys... but for half the price!?
I tried the search function and it sucks!
Thanks,
Drew

A friend of mine (here lurking but doesn't post 
) bought the ebay one for $20 and it works fine. No problems whatsoever.
Compared it side to side with the UR...and I couldn't tell much difference.
Another one of my friend's has the UR pulley. Driving both cars, they feel the same.

you dont want or need the full set on the TL
The crank pulley underdrives the ac slightly, as well as the ps and alt.
The weight loss at the crank is where you get the ~hp gain~, its not `new` hp, just the engine revs up to vtec way faster. The major weight loss is worth a figurative/comparative 8 hp
By running the pullies on the alt and ps you risk them being too slow for efficient operation-- at low gas saving rpm driving
Mount the crank pulley on the car, and the others on your desk as pen holders
Numerous CL members have used BOMZ brand for many years with no issue
I have no knowledge of the 20 buck pulley, but even I have a limit of belief
as to ~whats toOOOO good to be true~

screw the cheap brands. The last thing you want is a cheap pulley that's not 100% true and end up shearing your crankshaft. Spend a little extra for the UR under drive pulley and you'll be happy with the performance and worry free.

I agree to buying quality brands/constructon
AND this alleged imbalance issue is an internet rumor
They make all the pullies from a `BILLET` of aluminum- thats a square compressed block of metal - placed in a computer controlled 3-D cutting and milling machine
Some hours later that square is now a pulley or a wheel or whatever you told the machine to make for you
When Its a CNC part- there is no tolerance for it being off weight or balance- its a cut-machined part!

Correct, but some of these manufacturers that are making these parts for cheap are also using older model CNC's that need constant maintence or the quality of the parts they produce is compromised. I know because I sell CNC's often at work and have run into issues with older ones.

I dont know who ralco or any of the other makers are and what the age of their machines and cutters are.
I am going off info from trusted ziners whi have bomz brand- I cant say about any others
Quality is what I am concerned with, as I said before- 20 bucks and expect any sort of quality?-
thats beyond my belief point of- too good to be true!

Not that I doubt you "01tl4tl" but can anyone else confirm or suggest not to install the other pulleys?

for more than 600 watts- get the stock sized lightweight pully for the crank and dont change any others
Josh- Excelerate- had some in the stock size made custom from UR- so he would have them when people like you with big stereos want power as well
UR is the only maker of stock size lightweight.
The underdrive pulley doesnt spin the alt fast enough to make power to run the car and the stereo- thats why you go with stock diameter-

and it doesnt add hp, it frees up what the excess weight is robbing from you
