Where can the LT1/LT4 intakes be improved if any?

What ever came about from that one individual who was going to manufacture an LT1 out of thermoplastic material. I know the material and process is an expensive one but has anyone tried making this into reality.

i got a reply back from someone over at more performance.. he said they gained 100hp over the ls6 intake on there 427ci monster. said it gained from about 4500 on up and they spun the 427 to 7000rpm. im wondering how much hp/tq over 4500 it would give me after i fully port my afr's (310cfm@600 or about) also awesome low/mid lift #, solid roller etc.. FAST or DFI. i think a good sheetmetal setup could net 50rwhp very easy. so 500rwhp N/A shouldnt be out of the question.. jim lab made more then that because of his raised runner heads. (flow like ls6 heads). now the problem $2000 for 50rwhp

I will be doing some serious porting to my LT4 intake for my 396 currently being built, being topped off with AFR comp port 210CC LT4's. I will have some welding done behind the injector bosses, and maybe around them too, depending on how crazy I decide to get with it. I will try to get some pics up when its done.

So who can raise the roof on the intake?

Dave,

Getting the roof raised on a LT1/4 intake is not hard if you have a good aluminum welder. I usually machine a patch for a aluminum plate and have that welded to the intake. Then the rest is port work and matching the intake to the heads. Then when it's done just powercoating it again.

You can also check with Jordan about this, I know he does intake porting.


MadMaxx,

Yeah Mores intake is not cheap, but that puppy made that power with more than just that intake. The $2900 headers they have helped too.

I think these guys just matched them though

The new LSX Comp/FAST intake should be a good alternative

Did anyone by chance get to read the new "Corvette Fever" magazine, anyway they have an article on Wilson Manifolds based out of Ft. Lauderdale, FloridaWilson Manifolds that's currently producing LS1 manifolds called LSX manifolds with significant changes to the inside tract. Maybe someone in the local area can spearhead a call or visit with them directly to see the feasibility on producing a polymer intake for our LT1's. Thanks

Actually Wilson manifolds designed the LSX intake and then FAST which is a division of Comp is selling it.

Polymer intakes for a LT1 probably will not fly since they cost so much to make. This is a big investment by FAST to make this intake.

Here are some pics of the intake

In that last one you see the Wilson Burst panells for N2O

Hey Johnny, Im close to them and went down to get a tour of the place about 2 months ago. Nice looking stuff but $$$. As far as a polymer intake for LT1s, wouldnt ya think they would need a large demand to make those?

You could easily design one that would work for both an LT1 and a traditional SBC, or use the same basic pattern with different inside bolt locations and adding the cooling passage on the front of the SBC one, so you really could do very little design work and end up with a manifold that would cover 3 very popular engines (pre ’87 SBC, late SBC and LT1)

Anyone call or paid a vist to Wilson Manifolds............... By the way WS6 TA that was a good idea to float to Wilson. There would be a nice number of individuals who could use the intake besides on just LT1(4).

Let me clarify first that I emailed Wilson Manifold directly and received a response stating that they worked with Comp Cams/Fast Fuel Injection on the design for the LSX intake manifold. Has anyone inquired with Comp Cams on whether its possible to work on a LT1 intake project. I know they produced a thermoplastic intake for 5.0 crowd a couple of years ago. Well if anyone can call them that would be greatly appreciated.

Next time I talk to them I can ask.

The problem is there are so many SBC intakes I don't know if they would.

There has to be packaging constraints on this thing too. You would have to change the head bolt patterns rather than the intake since you can weld it up and start over on a standard SBC to LT1 conversion.

BTW that FAST/COMP intake (which yes Wilson helped design) is sell for $795. That's pretty dam good for a polymer intake manifold. They made it because the need for one was there, as far as packaging, and performance are concerned. IMHO converting a Stealth Ram to work on a LT1 is a better idea, than making a polymer intake. Putting some TBC on it would help that out even more.

on the right, a welded intake. the cross section is MUCH more consistant, and although the roof line is still not perfect, it is MUCH closer to what you would get from a Hogan, etc. not a stupid "ski jump" like the stocker

Jordon, could you please link some pics of the welding that you did behind the injector. Just trying to get an idea of what you did.

Thanks

Anybody know how well a TBC or a thermal dispersant coating will work on a LT1 intake??? I've been considering TechLine coatings... anybody?
