What do you have coming out of the turbo? I see in the second pic two 90*'s to get the pipe turned up, but then how do you get it into the turbo? What turbo is it? Take off the MAF and snap another shot so I can see the rest of the piping on that side... PLEASE!!!
And that link in your signature is still broken.
And sweet pipes man, I hope mine turn out that well.

Do the tubes in the Starion have "turbulators" in them? I thought the tube and fin ICs had less pressure drop (because the tubes were "cleaner") but the trade off was less temp drop. I know the bars/tubes in my spearco core are packed with these "turbulators". Just wondering what the difference in spool up is attributed to.
Im not sure about that, I know the Starion had a pressure drop of about 2psi accoring to my gauge. This is going from 10psi w/ the starion to no IC and getting 12psi. So I attribute the faster spool to less pressure drop and a more free flowing core. I was under the impression that tube/fin IC's had higher pressure drop but cooled better, and that the bar/plate had less pressure drop with slightly lower efficency.

I will snap a pic of that side tomorrow. Its basically a 2" 90* off the turbo and then I use a 2"-2.5 so that I can connect to the 2.5" IC pipe. I used a small 2" piece of pipe inbetween the 90* and the 2-2.5" coupler. Going around the radiator on the driver side you might want to shorten the radiator hose, my pipe kinda rubs on it, but it doesnt really hurt anything so I didnt worry about it. I will get a pic of that tomorrow.

Tube and fin usually flow more and "easier," but that's because the path is not as turbulent as it passes through the core. This is also why it's less efficient. The core will be a little lighter also.
Bar and plate (known as the "better" intercooler) is heaver, more efficient but also more restrictive as the air tumbles its way through. This is what gives the bar/plate better heat transfer. (Better numbers on the dyno also if you are so inclined)
The better I/C just depends on the application. For a Miata, you could argue the tube/fin because of the lighter weight, quicker spool, and adequate cooling because nobody runs horribly out of their turbo's efficiency range (except you freaks
) while a supra (or any "dyno" car) would be better off with the bar/plate.

Bust out the bible, Andy's right.
The Plate style generally offers less flow resistance, whereas the extruded-tube style tends to be more efficient.

There's some good core pics on this page. Looks to me like the tubes can't carry the volume that the bar&plate can because of the thickness of the fins. And I guess there's a variance in performance among the same types depending on the internals of the core. My spearco looks like the top bar and plate in photo.

"As a general rule, with a level playing field (manufacturing quality, both fpi's, tube size, thickness, & a hundred other variables), bar & plate intercooler cores dissipate more BTU's then tube & fin cores - per square centimetre.
Please stop, go back & read that sentence again, as it is the most often asked question, but the most misquoted answer of all time. Please also note that it is very easy to change just one specification of a core to make it better than the other & it must be remembered right now that heat dissipation is only one parameter of overall intercooler performance.
If there is enough area & volume available, I mostly recommend a tube & fin core to do the job, as it will get the temperature down close to bar & plate, but at less pressure drop & less chance of leakage."
Quoted from http://www.are.com.au/techtalk/intecoolersMR.htm.
This source seems to agree with what I was saying:
-Bar and plate cools better because its more restrictive.
-Tube and fin is recommended because of the (Miata) specific requirements.
I'll say this as well. In my post, by saying "efficient" I meant "cools better." Which is NOT the same thing. Even playas fu
k up..
I just did more damn intercooler research...... Found a crap load of contradicting information, which sucks!
What do you guys think about the first quote?

That is a carbon steel log manifold made locally by AutoLab. Its also got a JetHot2000 coating. Thanks for the compliments....
Sam,
Ill get that pic for you, I have just been busy and now its raining outside so its a no-go at the moment.
