Overkill S/C Pulleys

Anyone know if the quick change pulleys that overkill uses, are available anywhere else?

Shouldn’t any of these 8-rib pulleys offered directly from Vortech work?

They should, but I'm not sure if it would line up with the crank pulley. It would be a lot easier to find one of the quick change ones. That might be the way I have to go though.

Good point on the alignment, I’d be curious to see what works.

I haven't tried yet, I'm working on some other projects now, I was hoping someone knew where to get the overkill pulleys, because that would be a lot easier. This will probably be put off until later this year, when I have more time.

I actually pulled mine of Sunday and it’s just a regular Vortech brand 8 rib pulley. I’m upsizing (!) from a 3.6” to 3.7” pulley, trying to drop boost about 1 psi, to alleviate my HPFP issues where it can’t supply desired rail pressure at max boost/rpm. I’m hoping that a bit less boost will allow me to redline the motor safely and keep in the power band longer. I’ll report back on how it goes.

If you need better fueling on the high end :
LF4 ATSV Hitachi Fuel Pump
Tapout Tuning (AutoTech High Volume HPFP Internals Kit)

Bill522: thanks for the reply. Can you confirm that the LF4 pump internals work on the LLT HPFP?

I don't know if it will work for LLT.( I always forget that motor) .Suggest contacting Will at Overkill. I know the LLT is a totally different beast than the LFX, and I would hate to give someone bad advice..

This tensioner by Gates is the one you want. Much stronger tensioner than the Dayco one that comes with kit: GAT 38485.
