Haha thanks tackle. I wasn't sure if there was a more respectable and reliable vendor.

I've been watching a few Lightning vids on YouTube and I can't wait to hear that wine under the hood. There's definitely an audible difference between a stock pulley & a 4-6#. Zing zing brother!

What difference do the different pulleys make in sound? Just higher pitch and louder faster with the 4-6#? Or what?

charliedyal

Yeah. Larger pulleys spin the blower faster making the whine much louder. Also gives you more boost.

Wouldnt that top out an m112 pretty quickly?

charliedyal

There are guys running 10# lowers with 2.73" uppers seeing close to 21#s of boost (allegedly). Don't know how long that would last. But that bad boy is definitely spinning!

I found a totalled lightning at one of the local yards. Looks like it was t-boned by a semi around the rear wheel on the drivers side. I'm seriously thinking about pulling the whole blower assembly, fuel pump, and all the other crap I need to do the same swap. How much do yall think it will run me at the yard?

If you put a bigger pulley on the bottom the outside of the pulley is turning faster to keep up with the pivot(crankshaft).


A larger pulley on the blower makes it slower.

Same concept as a 21 speed bike or any pulley system for that matter.

Hell, offer him a grand and see what he says! LOL. It's a lowball, but it will give you an idea of what he thinks it's worth.

Stock on a L is 2.93. HD is 3" I think. 2.73 is smaller & moe speed.
