No thank you. You'll still fight me on it.
How about you test it and let us know how it works and confirm the temperature stays the same as stock?

You just dont have an answer for me. That's pathetic. You come in here crap on my thread and dont even give a suggestion? Unbelievable.
Your comments here are worthless. We're back at square one. Can't you see the flaw in your logic here? You come in ranting and raving about temperatures and you cant even answer the simple question of how is this product any different than the stock components?

Well then this whole thing could have been avoided if you would have just said:
"hey, have you done any testing to see if there have been any changes to water/oil/intake temps?"
I would have said "no, but i plan to -- however, development has stopped because of my current situation."
See?
Thread crap averted...

...Wowz. I would've liked to see what we're "supposed" to take into consideration with this stock replacement in the first place as well, but... I didn't see any explanation about it. I'm not trying to point fingers, but I want to know really, what Jantzen is "supposed" to be looking out for and why when, like he said, this is a direct stock replacement, just has a mount or whatever in it. Thats what I'm interested in seeing.

I don't see how any of this is difficult to grasp at all. Maybe the overly redundant and overly broken down (and therefore maybe somewhat circular and confusing?) explanations of Meyers did it.
Meyers says that the presence of the shield interferes with radiator flow. Jantz contends that the interference should be essentially identical to stock as the piece merely replicates the contours of the stock intake and battery boxes. So, at the end of the day, this set up, which is not in production, would move your battery and give you a pretty spiffy engine bay. It should exhibit essentially stock cooling characteristics (whether you consider that good or bad).
Personally, I did think the set up looked pretty good. I couldn't use one as I already have all that stuff moved/removed/something else there. However there are some things I'd like to fab out of simple sheet metal and I would hope they come out that clean.

There are two points.
First, the RX-8 if pushed hard needs all the cooling help it can get. Duplicating the OE radiator flow is a missed opportunity.
Second, whatever you put there will get heat soaked to the extreme. Care must be taken to provide heat protection where necessary.
One point I disagree with is ducting radiator flow away from the engine. As hot as the radiator air is, it stll provides cooling due to the high temperature coming off the engine itself. If you duct the radiator air away from the engine it will need to be replaced by another air source. This is tough to do within most racing classes, let alone a street car.

Listen Jan, were all here with blank checks awaiting your design. 
Just kidding, but either way, interested to see how this goes as I'd like to go to a racing battery by April, and I may just go the route Team suggested, or this route if it's done by then. Either way, thanks for the info from all ends.

This is why you see some of the trick smaller radiators that flow lots of air and then let it freely escape on open wheel cars like IndyCar and F1. Smaller radiator that flow alot equate to better packaging, aero and give a designer more flexibility when coming up with a design.
Here is an example: http://www.yearone.com/enthusiast/ar...e/garage18.jpg

So have you ever thought about those guys running such small radiators do not run your normal 92 or C16? Ever peer into the world of sprint cars and think how do they cool a 750bhp motor with a radiator the size of a laptop? Go stand by one running and soon you'll figure it out. Methanol burn rate at 1/8th of standard fuel. You can run it (off top of my head) like 15-18% rich without causing any real serious loss in power. So all the way through its burn cycle its being cooled wouldnt that mean less BTU being produced?

Hey, feel free to shoot down my idea? But what would the benefits / consequences of using aluminum black mesh instead of a solid plate. Then arguably you will conquer all concerns and have a wicked product?
I don’t know maybe I'm missing something obvious, but hey I'm trying to be constructive and I’m tired...
also I want one so sign me up.

We're running gas, with much more complex air routes for it to exit the car and the engine is crowded with no real way for normal air cooling to do much effect whatsoever.

Well, those small sized "laptop size" radiators are used only for qualifying. This along with Methanol as you mentioned all plays a key to keeping their engines cool.

This had zero direction towards Chris setup because it retains the OEM style.

I think you totally missed the point like Eric did. Bolded statement is the soul point I was pointing towards. That is the reason they can run such a small radiator (and the size I gave was an example not to be taken directly correct). Sprint cars were just a good example because everyone should have been around them at one point in their life. He was trying to point that with free flowing air they can run a small radiator because of that. Which is slightly right, but fuel is the big one.

Methanol does indeed help a lot, but don't undermine the air cooling and how open the engine is to get access to it. With as much HP they put out and the increased compression ratio they must have in order to put out over 800+ hp for the big dog classes, if you restricted and boxed in that engine the temps would shoot up easily. With normal sized radiators they use which from what I know is no smaller than the one used in our 8 I wouldn't classify them as small. That and the fact is they rebuild those engines after every 3-4 races, tops whereas we are using strictly a stock setup hoping to last over 100k miles. The real question is that is more relevant in regards to methanol's effect for an 8 is how much less temperature wise does the engine see with the same OEM setup. I know some people are using this setup, I'd be interested as to how much lower in temps they are seeing.
On topic; If the new setup retains the same restriction imposed by the OEM box then nothing is being lost, agreed.

OK, I decided to keep my Odyssey PC545MJ battery up front for now, rather than the hassle of running cables to the rear (have done it before). Don't bother asking for one. I don't have the time or desire to fabricate parts as a business.
Rough fabrication completed
Test fitment before final deburring and finishing. None of this will be visible upon final completion because in addition to using the Odyssey metal jacket for heat protection the entire assembly surface area will be encased in durable insulation material.
