Not sure if you guys check out the LFX section, but he's recently been doing testing on his LFX spacer and the ported manifold, and had great results. See the 3rd chart on this post here: http://www.camaro5.com/forums/showpo...&postcount=332
The spacer gave nice gains down low, while the intake gave nice gains up top...in all 15 hp and 15 tq gained. Very nice!
I don't think you'd want to run this spacer by itself on the LLT, as it seems this will still transfer heat into the LLT's aluminum manifold which is part of the big benefit of using the other current spacers on the market.
If I'm reading this right, you're implying running this GM part by itself with the LLT intake manifold? It wouldn't be possible. If you're running this spacer with the LFX intake, it's composite, so it wouldn't get that hot as compared to the LLT intake anyway. However you could use either the black isolator you already have underneath the whole setup, or you could use my spacer between the upper and lower intake pieces. It would take a bit of testing to determine which setup would be the best for the best/most useful power curve. Maybe both?
Jason...do you mind posting what this cost, and if you know the thickness that would be great info as well. |
If this piece is the same thickness as the LFX piece, it's about 1.125" thick. Even with the lower intake manifold piece, the LFX vs the LLT intake manifold height looks pretty similar, within +- 1/4" maybe? Try not to think of this as a spacer that increases runner length, but more as an adapter. Basically adapting a better intake manifold to your engine, nothing else.
My cost on the part from the dealer was $280, but I've seen it as low as $265 new shipped ground to your door. GM List price is $367.98.
I can't remember how much my dealer charges me for the LFX upper intake manifold, but it's quite a bit cheaper than the list price of $354.99.
A quick search online shows me that the cheapest place to get both the LFX intake, and the Traverse LLT lower intake is Summit Racing, for $506.94 w/ free shipping.
Aside from that, you will still need:
-bolts
-GM oring gaskets that go into the bottom of the composite intake
-the PCV line that runs from the rear of the pass side valve cover to the center/front area of the intake (the one you cut for the catch can install)
-The LLT evap solenoid hardline might work, but you will have to contort it out of it's original shape. The LFX evap solenoid hardline is recommended and is a straight swap.
-the LFX TB oring gasket (but you can use your LLT TB, and pretty sure the TB bolts also)
-The LFX EVAP solenoid w/ bolt (pretty sure it comes with the bolt if you but it new)
-You will either need to buy the LFX MAP sensor (& bolt) just to plug the hole in the intake, or just plug the hole with a pipe plug and some sealant. If you use something non destructive (like the map sensor) it will make the manifold easier to sell (to the LFX crowd) if you decide to .
The LFX intake composite intake, w/ aluminum lower part is about 12lbs lighter than the LLT intake manifold.
I think that should answer most questions about what would be needed? Unfortunately I don't have part numbers and prices available for everything as I'd need to go to the dealer and pick stuff out on the diagrams on their computer as it's not all listed for purchase on most internet GM parts sites.
Vararam intake may not be a straight bolt on, a different silicone coupler MAY be required. Stock intake, and all other aftermarket cold air intakes should work without any issues.
Am I forgetting anything?
Once this part shows up and I 100% confirm it will bolt on and work, I will have a complete setup with everything mentioned above that you would need to try on a car...
