new to the scene and wondering does anyone here have an underdrive crank pulley, any brand , on an ls and does it damage your harmonic damper? thanks for any info

 

The lack of a damper can damage the bearings. Either the ctr or the jdm b16 (i forgot which) doesnt have a damper and it seems to run fine. I dont know why that particular engine is the only one that doesnt. If anyone can elaborate, I'd like to know. I also know newer nissans have internally balanced parts so they dont need any kind of damper... maybe honda used similar technology but then stoped using it?

 

the gsr is internally balanced.

 

bump

 

this is a pretty funny situation.

one of my buddies told me that it would throw my bearings all out of whack, due to the nature that it would be unbalanced. My car 40k later, runs better than ever. His car, threw a bearing with stock crank.

Though it probablly wasn't the same problem, I found it ironic, don't ya think

 

pretty ironic... i bet you busted his *****

as far as underdrive pullies... i have all 3 Unorthodox racing pullies on my LS and they are great. PM me if you have any questions

PS... if you do get pullies only go with Unorthodox Racing, Not AEM
