We’re currently testing our production Cobalt LNF Turbo MPx lightweight crank pulley and we’re happy with the increased throttle response!
It fits well, installs in about 20 minutes with simple hand tools and its going to be VERY affordable! Ie, slightly above $100!
We’ll be releasing these for sale shortly. More details to follow.
Machined out of billet aluminum with a stainless steel crank snout pressed in
Weighs 1.7 lbs versus the factory 3.6 lbs. This is a savings of nearly 2 lbs, which may not sound like much, but when its attached onto the crankshaft and is part of the spinning mass makes a noticeable difference.
Same diameter as the factory pulley, so you use your factory belt.
Does not affect alternator output, or AC output
NO check engine lights
