Corvette FAST Manifolds and Throttle Bodies

Airflow engineers at RHS® and EFI specialists at FAST recently worked hand-inhand to develop a superior intake manifold for GM Gen IV performance applications. Designed for L92, LS3, LS7 engines using the latest RHS® design technology, the LSXR features a three-piece modular construction to allow for easy disassembly and porting. Extensive testing led to a runner design that was longer and less restrictive, allowing the removal of individual runners for modification, making this the most versatile Corvette part out there. Dyno tests produced gains as large as 16 horsepower and 18 ft/lbs of torque on a stock engine with a mild camshaft. Additional testing on a 500 c.i. engine netted even more impressive gains of 26+ rwhp. Constructed from advanced polymer material, the LSXR? is lighter, stronger and more heat resistant than comparable aluminum intakes. While it features a 102mm air inlet, it can be used with 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on fitment, allowing use of factory accessories without clearance issues. Designed for GM L92, LS3 rectangle & LS7 raised rectangle port heads. 16+ hp gains with stock displacement & 26+ rwhp with larger cubic inch.  Removable runners for easy porting.  Perfect bolt-on fitment allows for the use of OEM accessories.
