I bought a used whipple and after checking it over quickly i noticed that there is an oil leak which seems to be coming from the center of the pulley. Has anyone else had this problem with theirs? Does the snout have to replaced to fix it?

Also when you spin the pulley back and forth is there supposed to be some play in it? Mine has a little bit. If i spin it forward it spins smoothly but then if i stop and spin it the other way it seems like it stops for 1/4 of a second and then spins smoothly the other way. Is that normal?

 

Got the leak figured out, its just a vent hole. Now i'm just wondering about the backlash on the rotor.

 

No backlash.The coupler prolly going bad.There are a handful of companies that rebuild the nose drive.Can't remember site jus google (Whipple rebuild).
My setup is no meth pump gas intercooled.It is also a two belt setup (older style)meaning the whipple has dedicated belt.

 

Hmm i read that it's pretty easy to replace the coupler? Or no? Also do you think you could snap a pic of your setup? I want to see how you did the intercooler.

 

635$ to rebuild it by http://www.thehighspeedlab.com/

Is that the average price?
