I know, I have a MMS FAST 92 & LS2 TB leftover from my 99 ls1 Bolt ons prior to my custom 396 build/install.

Uhhh ok. I made 750hp at 7psi with an non-ported oem LS2 intake manifold. Going to run the same on the current 403ci build which will be closer to 950hp. Plenty of fi cars running a LS2 intake manifold making big power.

I merely made a post that shows how much more power the fast makes on particularly the ls2, and you gonna talk boosted to show how the manifold performs bahahaha there's countless posts on this topic which after research shows gains over the stock ls2 manifold I'm sure there will be more na guys that will chime in.

In fact it makes less power than an LS6 does in spite of the LS6 having a much smaller 78mm entrance versus the 90mm with the LS2
These are the facts proven time and time again in various independent dyno tests (the results in this thread comparing it to my ported FAST as another glaring example of just how bad it is)
Here is a very thorough intake manifold shoot out that once again shares the exact same information.....
Richard Holdener talks quickly about the LS2 intake right about 6 mins into this excellent informative manifold shoot out video
Few people have dyno'ed more LS combinations than Richard Holdener with the exception of Steve Brule from Westech Performance who is usually pulling the handle on the dyno during most of Richard's testing

Add a ported FAST and pick up 50 at the wheels with no other changes.....the LS2 is almost the worst flowing cathedral manifold ever produced.....2nd only to the original LS1 intake that came out in 1997.

Joe.....In your response #12 above you "quoted" the wrong forum member here. Navy Blue knows just how bad the LS2 is

My response was addressing the negative ie incorrect comments regarding the LS2 im.
It flows well enough to make 800+hp...750hp on my C6 that was tuned conservatively by...wait for it...WESTECH!..at just 9psi.
I'd say it's anything but a pos that doesn't flow well. YMMV.
Are there other options? Certainly...for more $$...which the gains were minimal for the money on an FI car considering the risk. Ie FAST intakes have shown many times to fail under enough boost vs an LS2 im.

It's ok to have different opinions and experiences tho.
Carry on.

You can blow enough air through a garden hose to feed an LS2 if the compressor is big enough. Doesn't quite work that way when the LS2 is trying to suck enough air through the same garden hose. What works F/I has nothing to do with the needs of a naturally aspirated engine.

I refuted that with facts..it's capable of waaaaaay more power (and tq) and works well for many of us.
"Gains" over xx product in ONE application on a 6.0L is hardly "trash" lmao!
Need to see the graph showing showing an increase of 350bhp/225tq on an LS2 manifold? Trash.

Yes tony I caught that and thanks for all your input and extensive work you put into your porting and testing, the gains are really substantial on my build and really pleased I did business with you. Cheers from Jacksonville.

That doesn't change the fact many FI builds have made plenty of hp on a ls2 intake manifold now does it?

How about "the LS2 Intake is TRASH in a NA Application/build"!
Happy Now?
Maybe stay in the FI & P&R Section where you/we can be Productive?
LOL
