I hadn't really put any thought into this till i was jumpin around the forum reading a few posts. and i read one about the ctr or was it ebay ctr pulleys not having a damper built in it. and that you should use one that has a damper to help with the vibrations and all. well what about thin aluminum pulleys? thing is i got a crank pulley that was custom made at a machine shop out of all aluminum. looks kinda like this
im just wondering if its gonna worse off then the ctr style pulley or should i just put my stock one on when i put the motor in?

 

you're not really gona get a clear cut answer on this. some people will swear up and down that you need a fluid dampener, other people have run a, say an Unorthadox Racing pulley on their DD for 50k+ with no issues. personally, i know a few cats running them with no issues, so i don't think it hurts anything, and its not a bad way to free up a few ponies, but like i said - opinions vary.

i say if you got that sucker custom made, hook her up and test it out.

well its not a daily driver by far. weekend drag car to tow to the track. so i guess itll be alright. this ones not unorthodox it was custom made at a flowserve machine shop. and i ended up with it for free so i couldnt complain.

 

Since it's a dedicated race car, I say go for it. If your oil pump takes a ****, then you won't be without transportation. I assume you're also going to rebuild the engine every so often, so it won't be as big of a deal.

If it was a daily driver, I'd say avoid that pulley like the plague.

 

yea ima just go for it anyways. motor is fresh from rebuilt still waiting on oil pump water pump and timing belt. but block and head has just gotten back from the machine shop. and i dunno how long i plan to run this ls/vtec 12.2:1 should be good for 200whp but im in the looks for a bare b20block 14:1 gonna be my next build. shootin for closer to 250whp
