the bar/plate design has been done... its not as hard as you may think..

It requires most of the manifold to be fabricated however.

 

Oh.. for sure.
I had a design at one point... I just wasn't satisfied with the cooling ability.
To get it to the point I want, I'd have to make it bigger... too big.

 

You'd be surprised, the performance was significantly better in all aspects. If i remember correctly it was only like a 4 inch x 4 inch cross section

 

How deep?

 

4x4xwidth of manifold

water flows through 4x4 side
Air flows through 4xmanifold width side

Air flows down the front of the manifold turns around the bottom and flows up through the intercooler and into the ports

 

Well, it is very cool to hear, and the data I've seen is very convincing too.

The other reason why I've decided to stick with the Opcon's is the cost part.
I don't think people would like to shell out an extra $200 for a bar and plate water to air cooler, when they can just use the 4 cores they already have.

I'm very interested in looking into a one off system like that in the future, though.

 

It's not clear to me how these Laminova's cooler cores are rated to BHP...
A heat exchanger has a flow capacity vs. resistance and some sort of cooling efficiency vs. airflow vs. temperature curve. And with these parameters you design a compromise for your particular application. Trade flow resistance for cooling efficiency...

And what do they mean with this "unrestricted manifold"? Our 4 laminova's cores can flow 480BHP without any flow restriction??? My common sense say this is not going to happen in this universe..

I do like the compact laminova design, only the LSJ layout is crappy. On the Opcon site you can see a proper design of an laminova cooled manifold: http://www.opcon.se/www/files/lamino...cool_21apr.pdf

Going to read the How To... :-)

 

That is not too much different than what we have already, minus the runners and the fact that GM has streched it out and folded it in half

I would try and keep the laminovas - they are very efficient and have a much larger surface area than a bar/plate if you had to size it to fit in our cramped space.

 

The cores are rated in "BHP" as a factor of air flow and temperature reduction. This is how many other water to air inter coolers are also rated.
The factor I'm designing for is now just plai old resistance. I've already figured out the maximum acceptable slot size for the cooling and flow trade off.

The term 'unrestricted manifold' is more the idea of the manifold itself (without the cores) having a very low resistance, compared to the flow guides for the cores themselves.

An ideal intake would be a straight line, with no bends and smooth transitions.
Inlet from compressor -> Laminova cores -> outlet to head

The fact that every SS/SC owner already has a set of 4 laminova cores available to them is the main reason for staying with them. It would dramatically lower the purchase cost for the end user.
As well, I wouldn't have to worry about suppliers crapping out on me, as I've had this problem in the past. It's not fun when you have 10 guys waiting for a product, and your supplier says that you have to wait 3-6 weeks for parts.
Anything longer than a 14 day complete lead time is unacceptable to me.

 

Added updates to the second post.

WRT the design process, the runners didn't seem to fit in my initial design, so I'm now trying a 'back to front' method of trying to move the cores.

 

gee now i see why its so restrictive

 

Can't wait to see where this goes . Wasn't the Time attack cobalts intake manifold completely reworked compared to the production version?

 

Damn I Want One But I Don't Want To Deal With The Pulley's And Belt
I'm Talkin About The Re-assembly..lol

 

That stocker doesn't really complement the TVS too well, does it?

I'm not sure what GM did with that car. The only info I can find on it, is what GMPP stuff they put on.

It's not that hard if you have the right tools.

 

very nice omega. I've been working on modifying the stock intake for a lil while. I can't wait to see your results

 

im sure a better mani with the tvs will crank out some serious hp...

 

i think one of GM's sponsored racecars was where the dual pass idea came from dunno if it was time attack or another one, but to my knowledge they all used the same manifold on the LSJ. The H/E was changed to a Griffin though.

 

Oh.... I remember now...
That was that goofy looking dual pass concept.... except the one used in one of the cars was actually a single pass... in one side, out the other side. It had the one end all hacked up, with a big AN fitting welded on.

 

Yeah, that is somewhere in the 300HP LSJ build book.

Dual pass gave real benefits over stock
They tried a "3-pass" system, but power gains were minimal... (3-pass probably means here that they used (3?) separate cooling inlets and what looks like 1 combined outlet on the other side.

(Not really getting that one. Like Omega 5 says; with a combined outlet on the pulley side you can easily make a complete parallel system. Coolant enters, split into 4 Laminova cores and exits pulley side. :-) )

I know the stock setup has the coolant flowing from the downside upward. What would be any negative effects of routing the cooling from top to bottom?

 

In this new setup, I'll have it flow in one single pass.... no looping.

WRT the comments made in the porting thread, if you simply reverse the flow, you'd could possibly see lower IAT2's... but since I've never tired it, I can't be certain.

Also, you would have to reverse all the cores as well, as they are set up to flow in one direction.

 

ewww, good info. I didn't realize they were set up to flow in one direction. I'll give it a shot when I have time. I might just go to a dual pass then though.

 

Yeah. Check out the info I posted in the how to. I mentioned how they flow (big hole is out, little hole is in).

 

im so proud of myself, because i know omega!! he is like a hero to me!
