Thanks. As for the oil temps, After about 20 minutes or so of a high idle the temps got up to about 200*. This was on a ~30* day. Coolant temps were up there as well but as soon as the e-fan kicked on, they dropped like a stone. Once I started driving though, within literally 30 seconds, oil temps were back down to ~140* which is what the t-stat is. So it looks like they work. We'll see how it goes in the future when the ambient temps start to rise.
Worst comes to worst, someone mentioned a Harley e-fan as it would fit nicely around those cores. If it does end up being a problem, I'll start off with one fan, then add a second. I really don't see it being a problem though unless I'm dead stopped in traffic on a hot day. But, we'll see. I've been wrong in the past.
The only shitty part about it is I won't be using the Motec to control the oil fans. I have 1 output left and I'm keeping it for Aux stuff
FWIW though, a very close friend of mine and I will really delve into his FC in the future. We're planning on doing exactely what you're suggesting. We'll be welding some brackets on his radiator, and mounting the oil cooler fairly tightly with the rad, so like you said, when the fan kicks on, it should pull some air through the oil cooler. We'll see how it goes.
I wouldn't mind seeing some pics of that
Looking at your setup, I think I would've come to the same conclusion as Trots, I wouldn't have expected it to work very well either, However, your logic is undeniable and the emperical proff speaks for itself. Well done.
BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Haters. I blame 2Fierce, he's the one that planted the seed in my head in the first place. "Why don't you just go FMIC then!" after telling him I'm going to be focusing on Drag racing for this season to test the waters (since there is no other form of organized competition within 300KM's of me)
I'm going to try to make it down South for a few different track competitions, see how I like them, and go from there. The turbo I have should be decent for RR, possibly even Auto-X anyways. I might be hooked on the drag scene though, I'm feeling the itch to show up a couple big blocks. Either way, I'll see how this setup fares, and worst case scenario I'll fab up something new!

If you're mainly getting into drag that I think the FMIC would be the way to go as long as coolant temps on the street stay in check. The FMIC, I would venture to say, is probably going to give you the best IAT's mainly becuase of he monster fricken cores you can get up there. For RR or auto-x (what I'm into) I think the VMIC/HMIC is the best way to go. Allows all the exhangers, including the brakes, to get their own source of ambient air.
Taylor, I hope the piping you got is aluminum, 2", and was real cheap. Otherwise there is no excuse for your laziness! Also...did you buy a meth kit yet?
----------
TT, I gave taylor my old HMIC core to use for his fmic because he's a rockstar.
Its not huge by any means, but it will flow for what his needs are.
I will post a before setup and after setup when my new project is done in its own thread in the FC section, see I ended up taking my haltech/engine core, and anything valuable I could off that car and sold the shell and leftover parts because I bought a Widebody....got my engine rebuilt/streetported/prettied up while it was out, and now the fabrication starts all over again. Using a Greddy core this time, but I'm cutting it, its way too big for my power levels and car goals. but now I'm threadjacking....
on the oil coolers, thats exactly what my fabricator suggested, to put the fans on the mocals and link them to a toggle switch so whenever I'm in cool-down at the track I can just turn em on, but I wanna try using the stock oil cooler first, if it is complete fail I will switch. Because the setup is like 600$+ for the coolers, fans, SS line, -10AN fittings, brackets, ugh.

yeah, about that......
The answer, Alex, is "What is, none of the above?"
Yeah, I've got my alky though. Snow performance, twin M6's and just ordered my M1.5(?) pre-compressor nozzle.
----------
The kit I bought also happened to have a Greddy 24 x 12 x 2.75 in it, so I'm going to see how it is, and worse case scenario ditch it and use your IC v-mount styleeo.

I was thinking about tapping into one of the lines and throwing in a thermo switch so it's all automatic. MAYBE a toggle override in the cabin but probably not. Like I said though, I don't think you'll have a problem as my temps went from 200-140 in a matter of seconds. Of course it was also 30* outside so we'll see how it performs on the more hot, nasty humid NE summer days

I would really like to wait and run the FMIC to see the results, and then possibly build a VMIC with the same core and see where it stands for direct comparison.
I wish I logged temps on my old HMIC setup...
but honestly that setup was so fail
-piping was poorly sized and wasn't even that short
-turbo turned out to be blown and leaky
-oil pan was destroyed prior to rebuild, and prolly leaking slowly
-gas tank had a leak(unrelated but it was rubbing on the exhuast and might've almost killed me if I hit a bump hard enough and the piping was hot enough)
-coolant lines were falling off
-ss oil lines were leaking at the crimps, new setup is using OEM for now.
It was just a complete disaster! If I could do it all again I would have bought a clean well running t2 and tried to mod it slowly as I daily drove it, fab work = insane down time and $.
Just a heads up for other ppl considering their options, make sure your car is set in all the other areas before going out and getting Fabwork done just to be unique (my previous case).
Learn from my mistakes noobs! (looks at Trot)

Id like to see the noob build his FMIC, log temps - all of them - make note of the ambient temps, and then use the same exchangers in a V/HMIC setup and see what the difference is. The best I'll be able to do in the future is log my intake temps with and without a vented hood. I'm really curious as to those results.
Fab = insane downtime. Yeah I can vouch for that. I'm in month 25 of my swap. Yes, over two years. The bulk of that time was all the fab work. I think I've built more pieces under the hood than mazda has at this point Seriously

Anyone have done a V-mount with the Radiator on top and the Intercooler on the bottom? It seems like beside the IC ducting routing might be troublesome, the always hot Radiator should stay on top for heat exchange reason for all driving condition. Any feedback?
If someone had the V-mount with Radiator on top please show some picture and detail on your set up. I am very interested in the result. thanks.
