LSA Gilmer Drive

 

As many of you already know, LSX Concepts has been at the forefront of Muscle Car LSA accessory drive kits for some time. As always, we strive to innovate while moving forward. We realized the need for an LSA drive system that allowed the use of High Mount A/C so there would be no need for frame modifications to fit the LSA in your classic muscle car.  We currently have two LSA accessory drive kits on the market and now a third in development.

Our Standard LSA/ZL1 Accessory self-tension drive kit for your street machine/muscle car is reminiscent of the simplest 6-71 blowers drives found on muscle cars and drag cars of the 50’s, 60’s and 70’s. It’s a perfect fit for your show car, and weekend fun car running a basically stock LSA configuration.

 

For our more performance oriented customers wanting overdrive pulleys options and taking the LSA supercharger to its limits on the street we developed our LSA Heavy Duty Race Drive. The Heavy Duty Race Drive has performed well beyond our expectations. Its flexible design accommodates the change in pulley sizes while increasing the upper pulley belt wrap where it’s needed. It’s perfect for your Autocross/Road/Endurance race car utilizing a rigid belt tension system with 2 idler pulleys.

Always move forward, we felt we needed to explore the 6-71 belt drive style that partly influenced by our original LSA/Zl1 accessory drive kit for the street. We took it to the next step by developing an LSA Gilmer Drive system. During the design phase of the project, we decide to create a no-slip Gilmer drive as cost effective as possible for the performance enthusiast. With that concept in mind, we created a design to accommodate the switch over while still keeping the price affordable and maintaining the ability to use high mount A/C

Our LSA Gilmer drive upper pulley is designed to bolt directly to a Lingenfelter 10 Bolt ZL1/LSA pulley hub. Often, customers pushing their superchargers to the limit already are using overdrive pulleys and already have a 10 bolt hub installed on their LSA superchargers.

Our lower LSA Gilmer Drive pulley will bolt directly to an ATI Super Damper PN# 918854 ,917278, or 917266 or the Lingenfelter LSA/ZL1 Harmonic Balancer PN# L220050709

Being cost conscious, by using existing components in the marketplace would limit the number dampeners changed and superchargers that would have to re-machined to fit yet another pulley hub.

The LSA Gilmer drive is currently available in stock, 3%, 7%, 10%, 14%, 18%, 20%, 25%, 29% overdrive ratio’s using an 8MM HTD 2 inch wide belt.

LSX Block’s – Standard Deck and Tall Deck

One of the biggest hurdles with building a tall deck LSX block is finding the right accessory drive brackets to fit the tall deck block, The LSX Concepts LS brackets have been specifically designed to fit both standard and tall deck LSX blocks similar to the RHS or GM LSX Bowtie Block. We designed our accessory drive brackets to fit multiple deck heights. Our bracket will accommodate anything from the standard deck (9.200) to the taller decks (9.700) of the LSX blocks.

It doesn’t matter if you are running a junkyard LS1/LS3 or a 9.700 deck height LSX block.  Our LS brackets have slotted bolts holes matching the lower block-mounting bosses to accommodate virtually any deck height for the LSX block.

ZL1/CTS-V LSA superchargers Calculating Boost on your ZL1 / LSA swap

So it seems the ZL1/CTS-V LSA superchargers are the hot swap these days, they are all over eBay for as little as 500.00 and one of the primary reasons we developed our LSA Supercharger Accessory Drive kit. It’s like the 60’s again when we had all the 6-71 and 8-71 blowers laying around for your hot rods. Note: GM called their Diesel 2 cycle supercharger for the numbers of cylinders and the cubic inch of each, hence 6-71 and so on. Now we have the ZL1/CTS-V LSA superchargers just begging to be on your LS swap in your muscle car.
