15 BLOG_IMAGE_678 By now, the LS community is well versed about the LSX Intake Manifold from FAST. Testing has shown proven horsepower gains with the LSX manifold<!--preview-->, however, this intake only fit LS1-style, cathedral-port heads leaving LS3/L92-style, rectangle-port heads without an intake upgrade solution. Until now…<!--more--> The engineers at LINK_TO "FAST", "http://www.fuelairspark.com/" teamed up with the airflow specialists at LINK_TO "RHS", "http://www.racingheadservice.com/" to develop a three-piece, polymer intake manifold for rectangular port GM LS3/L92 engines. Testing on a stock LS3 engine with a Big Mouth 102mm Throttle Body™ produced gains of 14+ horsepower and 11ft/lbs of torque at the flywheel over the stock intake. BLOG_IMAGE_679 Following the path charted by the original FAST LSX Gen III Manifold, the new LSXR 102mm Intake Manifold features a three-piece modular design that allows easy disassembly and porting. Extensive testing led to a runner design that is longer and less restrictive, yielding both torque and power gains over the stock intake. New to this design is the ability to remove individual runners from the manifold for modification. BLOG_IMAGE_680 The LSXR is constructed from a proprietary advanced polymer material, which offers a host of benefits over aluminum aftermarket intakes, including lighter weight, strength and improved heat dissipating characteristics. While the LSXR features a 102mm air inlet that is perfectly suited to the FAST Big Mouth 102mm Throttle Body, it can also be used with stock or aftermarket 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows use of factory accessories without modification or clearance concerns. The LSXR manifold is designed to fit a wide range of applications with little or no under-hood modifications. It even fits C6 Corvettes without having to modify the firewall. BLOG_IMAGE_681 The FAST™ LSXR™ 102mm Intake Manifold (Part Number: #146102) has a retail price of about $1,000. Replacement runners are also available for about $480. 0 2009-05-03T21:25:07-04:00 382 fast, fuel air spark, ls manifold, ls3 intake, l92 intake, ls7 intake, lsx manifold, ls performance intake, ls performance intake fast-lsxr-intake-manifold 2009-05-03 active /uploads/blog_images/0000/0677/FAST_LSXR_Thumbnail.jpg 2009-05-03T21:37:11-04:00 4 1889
