Chevrolet Performance has really made headwind into the crate engine market with its line of LS powerplants; a complete LS3 6.2-liter can be had for as little as $7,570 from GM Performance (PN 192044097). The good news is that price includes a substantial amount of goodies, such as the ignition system, manifold, injectors, throttle body, exhaust manifolds, water pump, balancer, and an automatic flexplate. That’s 430 hp and 424 lb-ft with a 24-month Chevrolet Performance warranty!
If this route appeals to you, then you’ll also appreciate the Chevrolet Performance Corvette Accessory Drive System with A/C (PN 19155067). This package comes with brackets, A/C compressor, power steering pump, belts, the tensioner assembly, and idler pulley setup for $850 ($800 on Summit Racing). Yes, this really is a one-stop bolt-in deal, and since it’s based on a Corvette package, it’ll tuck in nicely and make most retrofits that much easier.
For this combination, we decided to put our factory stock LS3 back to work, only this time with the front serpentine assembly, and let ’er rip on the dyno. The combo has already generated 501 hp with a set of long-tubes on the engine, so we wanted to see what it would produce when subjected to a healthy dose of forced induction.
To make it happen, we spoke with ProCharger, who supplied us with its LSx Serpentine Drive Kit (PN LSx SDK) with the optional D-1SC supercharger upgrade. The LSx system is designed to be a compatible with the factory serpentine drive and comes with everything you need for an easy install. All you need to do is let ProCharger know which LS engine you have and whether or not you have A/C or power steering.
This month we’re concentrating on the LSx SDK install, but be sure to come back in the upcoming Sept. ’12 issue, where we’ll give the full discloser on our ProCharger-packing LS3.
