Want more POWER! The FAST LSXR 102mm Intake Manifold will deliver it
 |
FAST™ LSXR™ 102mm Manifold |
|
|
Airflow engineers at RHS® and the EFI specialists at FAST™ recently worked hand-in-hand to develop a superior intake manifold for GM LS performance applications. With models available for all the popular LS engines, 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. Regardless of the application, dyno testing has proven these manifolds deliver significant bolt-on performance gains in stock applications and gains upwards of 25+ horsepower in larger displacement or highly modified combinations.
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 the use of factory accessories without modification or clearance concerns.

AMERICAN QUALITY SINCE 1957
For over 50 years, the name Milodon has been synonymous with premium quality racing components. From its founding in 1957, Milodon's objective has been to incorporate state-of-the-art manufacturing technology, aerospace caliber materials and stringent quality controls to produce true race quality performance products of exceptional value. Milodon's roots extend into virtually all forms of automotive and marine competition. Milodon has taken its advanced technology to the street, manufacturing a wide range of race quality products to enhance street performance and reliability.
It's important to note that the majority of all products in the line are made right at Milodon's Simi Valley california facility. Included in these in-house capabilities are such operations as CNC Machining, thread rolling, gear tooth cutting, metal forming and welding.

Why do i need an aftermarket oil pan?
each pan is designed to provide optimum performance for a specific application. That's why Milodon makes over 150 different models. Drag racing pans assure an ample supply of lubricant under rapid acceleration, while providing optimum power; circle track pans are engineered to cope with the centrifugal effects of hard turns. Off-road pans are built to deliver lubrication on all kinds of radical terrain while marine pans are designed to provide an ample supply of oil and reduced oil temperatures. Important features include oil control to allow good oil supply and maximum power, an increased sump capacity to assure an ample supply of lubricant at lower oil temperatures, plus design considerations such as required ground and component clearance.
How much power can an oil pan give?
On street-type applications a gain of approximately 3% can be realized. That's 10-12 "free" horsepower. Improvements are more dramatic in high RPM race engines. Think about this: 8000RPM the outer part of the crank counterweight is rotating at approximately 300mph(483kph). You know what air resistance is like, sticking your hand out of a moving vehicle at 60mph. Now factor in the extra resistance of oil and consider that the crank is rotating five times as fast! Imagine the power it takes to push the crank through this oil and air mixture. Now you inderstand the importance of proper oil control.
Can a windage tray really make power?
Controlling windage masked power! Milodon's "Diamond Stripper" tray out-performs any screen-type windage tray on the market today! It has hundreds of tiny louvers that very efficiently scavange oil from the rods and crank. Additional "free" horsepower can also be obtained by using a rear pan baffle to prevent the oil from "climbing" during acceleration. In high end applications a crank scraper provides maximum oil control.
