Ported (or stock) L92 Truck Intake VS FAST LsXRT 102 Trying to find some flow numbers or dyno results between these two and can't seem to come up with much..
I've seen a lot of the LS3 or the Fast (car intake) vs the OEM L92 intake but haven't been able to find any comparisons between the OEM truck intake (preferably ported) vs the Fast LsXRT 102's

there is not a fast 102 for l92/ls3 heads. I will be running an ls2 portworks ported l92 intake with my ls3 heads. As is, a truck l92 intake outflows an ls3 intake so better if ported. Fyi.

I wonder if the LSXRT top shell and runner assembly will swap over to the LS3 bottom pieces.
Maybe we're all better off with a Holley Hi-Ram and intake manifold gaskets that keep the heat transfer down.

I know the LSXRT top fits the LSXR runners (I would use the RT runners), the base is the same. But you right there is no RT LS3 runners 
RT cuts down the head flow less then X runner. And a straighter and better taper runner make more power and rpm on the engine.

I have not info on the GM L92 truck intake, But I know the cathy port ones are better then the LS1 and LS6. And the LS3 car in not that bad, its not worth getting a fast LS3 unless you spend the money looking for 5whp max. Or have to have some good heads, cubes and rpm to show a gain, but then you should have a better intake anyway.

just curious...if I ran an aftermarket hood on my 2010 camaro (654whp now through stock intake...centri+cam) I may be able to clear the Fast truck intake...I know the regular car fast 102 makes minimal gains even at my level...but it looks like the truck gains real numbers. You guys that have messed with it say its beneficial?
