Does anyone have a 3D model of the S/C intake manifold?

Even if you have a cutaway layout of the manifold that would be helpfull.

Any inside dimensions would be great too if you have that.

Models, dimensions, etc, nope.

This might be a good start though:

De mentions on the ports to the laminova cores are approximately 15mm in the middle tapering down to 12-13mm on the sides.

*** According to Opcon ***

Those ports should be at least 15mm wide up to 18mm depending on air flow.

^ nice

SKCobalt

Thanks guys. This will be a good start. I hope to make a 3d model of the intake but I may not have to if I can get things calculated and figured out a different way.

hehehehe, that got put in my favorites for "reference".

Do you think there is a better way? People have been trying to find a better way since they first hear the LSJ was going to have "Laminova" cores.

More I look at it the more I think we should just try making one with bigger cores. Ported to 18mm.

I think a total of 5 course would not be a bad idea.

good luck the problem isent the manifold its the exhaust side of the head

I didn't make it just came across it a couple years ago

SKCobalt

I'm not too sure yet. I have some ideas but have not made any calculations to support the concept at the moment. I don't want to make a claim that I have an increadible solution until I have some hard facts to support it. I realize that there have been a lot of people looking at solutions to cooling the charge air on these cars, some with success and some with failure.

I guess my next step is to get a used intake manifold, make some more detailed measurements so I can have more accurate calculations and see what I can do.

there was a guy on here omega5 i think and i think he made his own manifold but never said how it worked and then there was a guy who put a bell intercooler core in the manifold and removed the laminovas but never posted anf proof it worked

SKCobalt

Omega5 tuned my car but I haven't talked to him about his intake modifications. I also hope to talk to Flatgod as well about his custom intake with the killer chiller as well. His set up is pretty complicated though. I was hoping to make something a little more simple.

Have any of you guys seen this? I heard some of the svt cobra guys run this Design Engineering DEI 080110 - DEI Air Intake Charge Cooler Kits - Overview - SummitRacing.com

BS. It doesnt have enough surface area. Its just an intake restriction, though the theory could work. But if I was going to carry around a pressurized bottle of liquid for air charge cooling it would be nitrous with a fogger plate.

SKCobalt

That looks interesting. It looks as though the bulb was desinged pretty well to reduce its restriction in the intake tube. It could also be grafted into an intake either stock or aftermarked as they make 2.5" and 3" variants. My only issue with it is that I would have to run liquid CO2 in the car and I don't think I am allowed to run that type of system while Autocrossing.

For this to work for me I would have to run a setup that would automatically run the CO2 given a temperature reading close to the bulb so that I don't have to worry about monitoring the system and make sure that it is at its optimal temperature to cool the charge air. With this type of control I would run through a lot of CO2!

In some ways, I am leaning towards a system design that would not require me to fill or recharge it in order to keep it working and cooling the charge air. I woudl like to design something that is always on so if I deside to run hard, I don't have to play with a bunch of things.

i dont know if he even got it done i havent seen him on here in a long time does he still have his cobalt

SKCobalt

Yep. He still has it. I don't think he has been posting here very much anymore.

cant say as i blame him

SKCobalt

True. There are some glints of hope every so often though.

SKCobalt

Well I have an extra manifold now so I can start to modify it in the fall here. I want to do a single pass and open up the lamnova cores a little bit. I will have to source some of the other parts and get a chance to sit down and get some calculations done to figure out the other half of the system.
