Good point.
I run an AFCO 80125N.
22.5" x 18.5" x 3.0" core, 2-core, 1" core tubes, double-pass
26.0" x 20.0" x 3.0" overall
Biggest rad we could stuff in the FC without "major" mods.
Stock rad supports required to be cut.
Battery needs to be relocated or downsized.
Custom mounting required.

If you can't run a side-by-side, you can run two separate fans...
One pusher in front of the rad, and one puller on the back-side.

At least for FBs, the dual MR2 fans (1st gen early 80s vintage) fit really well and can be
separately controlled. I have them on my SA with dual wiring, relays and fuses. If one
blows the other keeps going and actually one is more than enough to cool the car in most
situations. I know this is the 2nd gen area but they may fit there as well.

Yeah... that's a big boy!

I'll be able to get two in ther if I offset them... one pusher and one puller I'm not a huge fan of because the pusher is just an obstruction at speed...

It should fit... IIRC the 2nd gen rad is bigger.... Good tip... Cheers

I like that idea... I was thinking of a split shroud concept, although I didn't think the stock plastic shroud material is rigid enough to be split like that. Would need a really solid bracket & fastener design to make sure it doesn't flex and interfere with the fan at any point during vibration/shock & any engine movement.

It doesn't.

I think a bracket like I described would hold it plenty....

Where do you read your temps from?

The one time I tracked my car with my v-mount I guess it wasnt sealed well enough and after 3-4 laps the temps would get to around 200, and then slowly climb. I stopped around 210 out of fear and coasted for a lap. they would come back down and go right back up. Is this safe or too hot when on the track? Does a second oil cooler help lower this as well?

Also...what do you guys have as a fan shroud? I have a basic spal fan with a sheet of stainless steel sandwiched between the radiator and fan. When the fan is on it works great, but on the highway it'll creep up till i turn the fan on and it goes back down. I've read about relief flaps but dont know what to use.

S4 T2, Vmount, megasquirt, bnr stage 3, koyo rad, etc

MoTeC with a CAN to the AIM dash, so I read it where the ECU sees it, right behind the Tstat at the hottest point.

It's fine, there's nothing wrong with that.... most modern cars run at that temp anyway

Depends, what are your oil temps?

Custom built AL

SS retains heat more than the AL will shed it... you're basically retaining the heat with that piece of SS. Also.... the fan needs to be spaced off the radiator at least an inch. This will pull more air through a larger area

Mistake number 1 is have a switch for a fan... it should be automated

I'm making a lot more HP and don't have cooling issues..... my temps on a 104* track day never saw above 185* coolant 200ish Oil. How well ducted is your VMIC setup?

driftxsequence · 07-15-2014, 01:28 PM

Oil temps followed coolant. I think I stopped once oil hit 215-220. Currently I have the oil cooler sitting in front of the radiator. I feel this is a mistake and needs to be moved, but for ease of installation this was my choice. undertray is installed, and there is a rad panel in the front. you can see the ripped foil tape from where i had it sealing the intercooler.

My fan is on a switch currently because the MS isnt clicking the relay. I can manually ground the relay and have the fan kick on, but the MS output wont ground it. it clicks on and off.

here is my v mount, and you can see the oil cooler partially blocking the radiator. How air-tight do I need it to be?

I appreciate the quick reply!

The oil cooler is heating the radiator and the SS panel is as well.

Probably something in the programming or just because megasuck

Very similar to mine, except bigger rad, bigger dual oil coolers, bigger intercooler.

Mine is air tight and probably water tight. The more air you can force throught he heat exchangers, the lower the temps will be.

driftxsequence · 07-15-2014, 03:19 PM

I appreciate it! Guess it's time to make some new brackets and get a second FC oil cooler.
