does anyone here make custom crank pulleys?

I need one for a supercharged D series.

i can provide a pulley (for measurements or whatnot)

i'd prefer a little bit larger diameter than what i give you, with no accesories.

just a light weight, larger than stock crank pulley.

i know we got some machinists in here.

 

i have a really good machinist who i get custom parts for my store from. im not sure what itd cost, but i would guess around 200 or so. but i can definitely get it done. in 303 stainless...

and thats just a random guess on price, im sure itll be cheaper.

 

youd need some sort of dampening on the pulley... so you couldnt just turn a solid piece out of billet.... youd be guaranteing harmonics and as a result oil pump failure

 

what do stock pulleys have?

 

stock pullies have this little rubber ring on them

 

exactly, then you just machine your pulley to accept that

 

or you modify the stock pulley's diameter, and then turn off the smaller pullies you dont want, and balance...

streetwerks you should IM me, and we'll discuss my good idea.

i'm with you, i am not at all for the lighten or lightweight pullies. I've done the reasearch and am not happy with the findings. Race engines only is how I took it.

 

i dont really need it "LIGHTER" just a larger diameter to produce more boost for a supercharger.

 

From what I hear, those aftermarket light weights without a harmonix balancer are just crap. The extra vibration causes your bearings to wear unevenly.

 

wouldnt it be easier to change the pulley on the supercharger? that one should be able to be billet without any problems.

yes, that is ONE way to upgrade boost.

but if you go too small, you risk belt slippage.

 

good point! i was just thinkin old school v8 blowers with the toothed pullies.

How are you going to modify the stock pulley's diameter? when he wants it larger

 

These guys may be able to do a custom for you. http://www.unorthodoxracing.com/
