now if this has already been done let me know what the out come was as far as long term or what not.
theres no extra vibes at idle havent had a chance to take it out on the road to see if it revs faster there or not though. basically what i did is took the middle ring out of the stock crank pulley. NOW before anyone starts with the negative comments i so understand that that part with the rubber insert acts as a harmonic balancer. so apparently the RKS and opther pulleys out there must be made balanced or else its not to big of an issue. please correct me if im wrong on that.
as i said this is just an experiment easy on the harrassment heh heh
anyways on to the couple pics
The one, the only, ME.
with aluminum pulleys out their pretty cheap i dont understand the logic.
I would be worried about balance and strength.
I work in a engineering dept. of a machine shop. I work with rotating assemblys all day long, and I would suggest you re-think what you've done.
In the first pic, you can see the 2 drill holes where weight has been removed to balance your pully ... now what you have left is just the original unbalanced cast pully. Rev that bitch up to 6k rpm and she'll vibrate the hell out of your bottom end. I could possibly see crank and/or main bearings going through hell.
Spend the $$ on a properly made harmonic balancer to save yourself the repair bill in the end.
jsut my 2 cents.
Nate
where are you all finding these pullies so cheap? the cheapest ive seen is 145. and im guessing that the aluminum ones are balanced cause theres no wieghts on them or holes. and the strength issue wouldnt be an issue cause that ring inside there is just floating basically with a rubber insert between it and the pully.
thanks for the advice all like i said it was an extra piece and was bored and took no effort to do. keep the ideas coming.
and also i dont feel any additional vibes through out the rpms but i know they mihgt not always be felt but are occuring.
