ok somebody fill me with info on the ls6 intake manifold. vs stock.


what makes it better? does it just bolt right up.? What kind of gains should i expect (i currently have a mti t1 cam)

are they worht the cost?

 

Flows better. Gets rid of the EGR fitting.

It is a direct bolt on, as long as you get the coolant lines.

On a bone stock motor, it is good for 5-15 rwhp. On a modded motor such as yours, you can expect 10-20.

Definite worthwhile mod and definetely something you need to look into if you wish to get the most power out of your set up.

 

Basically flows more air=more power.

This will be moved to external forum

what about the LSX mainfold?..it looks intresting, but also looks cheap.

 

Looks cheap!? It's stronger, stiffer, and lighter than the OEM material. That and for the price, I don't think I could ever consider it to look cheap. As far as it's usefulness for your application, It should provide more gains than the LS6 intake. Exactly how much, I'm not at liberty to say...

 

 

whats makes you say that?

 

um b/c the lsx flows better then the ls6 all across the curve?? it was specifically designed to flow better then the ls6, otherwise wtf was the point of making it? and for $700+ it damn well better. the bigger the cam, the larger your cid, the larger gain(it can feed a lot more air then the ls6, so the bigger setups can take better advantage of this). plus it can be port-matched for even better results.

 

prolly doesn't know....

 

The LSX doesn't make near enough power to be worth the money on a stock cube engine.

 

Hehe, I haven't a clue as to how much more hp it'd be worth on his motor. I suck at estimating hp.

 

how can you visually tell one from the other? does anybody know? pics please if possible.

 

ls1= egr protrusion

the ls6 intake has no egr...

 

So are you guys basically saying that a car that will eventually have all the bolt-ons and a cam, would benefit from the LS6 as bang-for-the-buck since the LSX isn't worth it over the LSX? I need to know because I plan on getting an upgraded intake manifold eventually, and will have the usual bolt-ons, cam, etc and wanna know which to spend my money on so I don't get screwed.

 

From what I've seen & read, the LSX is worth about twice the gain the LS6 will give you. To begin with they were also about tiwce the price ($800 vs $400). Now that there are used LS6 manifolds available, you can find better deals on them. Basically, the higher you go in the rpm band, and the bigger your demand is for air, the more gains you will get out of either. Right now with your setup you could see 10hp out of the LS6, and 20 out of the LSX (provided you have a good set of headers).

 

I'd assume you're talking about the 90mm version (along with the costly and required 90mm TB) and not the 78mm...please do specify when discussing LSX intakes.
I don't think the 78mm offers nearly enough over the LS6 intake (in most applications at least) to justify it's price.


Unless of course it's an SLP or Lingenfelter modified version that has the EGR provision.
Also look for the flat bottom (LS6) versus the 'wavey' bottom (LS1 intake).
