WHAT
OTHERS
SAY ABOUT THE LSX™ INTAKE
CHRIS TOLBERT LG MOTORSPORTS, WYLIE TEXAS
“The LSX provides a solid 15-20 hp gain right out of the box for our C5 Corvette
engines. It’s a straight forward bolt-on. The LSX really works for us.”
ANDY GREEN PRESIDENT/CEO, A & A CORVETTE SPECIALTY
“The LSX flows much better than a stock intake manifold and because of that, it
provides better performance when we make power upgrades than we would get out
of a stock intake. Things like cam changes, supercharging and other performance
improvements really perform better with the LSX intake.”

LSX™ 90mm Intake Dyno Results
Here's a dyno graph comparing the LS2's stock intake manifold versus the high-performance FAST™ 90mm LSX™. For this test the engine is the same. It has been outfitted with ported GM heads, COMP 1.75 rocker arms, COMP's 26921 valve spring package, and a COMP XE-R camshaft (228/234 with 114 degrees of lobe separation).

 Gains were to be found when the LSX™ was added to a completely stock engine as well as a highly modified engine. "At first the LSX™ and the stock manifold made about the same power down low," he says. "And then, right at 3,800 rpm is where it takes off. On a stock LS2 the LSX™ is worth 20 horsepower in the upper range. And that's a pretty consistent improvement. From about 4,000 rpm all the way
to the redline the LSX™ manifold is about 20 horsepower better." "It made even better gains on a modified LS2.
I tried it on an engine after I had added our full valve train, one of our cams, Dynatech headers and ported GM heads and it was worth an extra 30 horsepower versus all the same stuff with the stock intake. That was also without the intake ported to match the heads because I wanted to keep the comparison between the stock manifold and the LSX™ as fair as I could. On previous tests, I've found porting the LSX™ to match the intake port on the cylinder heads (which is easily done thanks to the LSX™'s three-piece design) consistently makes at least eight more horsepower."

REAL WORLD REVIEW
Printed here with permission from Performance Product Review Magazine - 2006 Issue, Page 11
In the words of Tom Cress, President of Lingenfelter Performance Engineering:
 "It is clear that COMP Cams poured a great deal of resources into research and development of this intake manifold. The LSX is a cutting edge intake that provides enormous advantages. Chief among the advantages is improved air flow that delivers a 15-20 hp gain over stock intakes – right out of the box. The LSX is a pretty revolutionary way to produce intake manifolds. It’s a three piece construction that offers a lot of flexibility, especially when it comes to doing any runner work. Porting is a much simpler process than any other intake. In addition to making interior work easy, it is light and really durable. Installing the LSX is a straight forward process for the C5 (LS1) engine. It pretty much is a simple bolt-on process. Using the LSX on a C6 (LS2) requires some modifications; however there is now a kit that makes it a simpler process for installation. There are not many things that can give such a quick source of horsepower out of the box. When you put that together with its flexibility and durability, the LSX is a real homerun. It’s a product that will remain revolutionary for years to come."
PPR: Would you recommend this product to others?
"Yes, the LSX is an excellent advantage, especially for out of the box power"
