Intercooler and oil cooler you will be set! For the most part

You're going to need a FMIC and oil cooler to track this car. Above 90* is when I start to run into trouble as far as water temps go.

I saw you posted oil temps but what were your water temps?

I'll be installing the Mishimoto radiator next month paired with DHM crash bar and my existing cooling setup. Unfortunately it's 120* this weekend. So I probably want be back to the track until the fall.

For those who don't know, I'm running a BTK at 25lbs of boost to 6300rpm.

What type of charge air temps do you see on track? I figure you track guys see the worst case rise and temps with your prolonged runs. I also assume that all the aftermarket ICs are going to produce similar results on track.

 

We have several tracks out here but the most brutal (long straights) has our charge temps about 20-25+ and oil is around 240* average.

 

Which oil cooler are you running Kevin?

 

FMIC is a CX Racing with some modification and it's done well by me. The oil cooler is a Derale heat sink type. I wanted to reduce obstruction to the radiator so that's why I selected it. Several of us are running it out here successfully.

 

As others have said, need an oil cooler and better intercooler. Keeping coolant temps down for the most part, but the hotter oil and charging air aids in keeping it hot,

 

I don't have a logger so this is all just dummy gauge experience, but this weekend I was running at Gingerman in 85-90 degree heat for two days. I never saw coolant go past 3/4 on the gauge, my oil though got to 300 and cut all the boost, really kicking myself for running out of time for the oil cooler install. I'm very happy with the mishimoto radiator the car ran better in similar conditions this year than it did last year.

 

3/4 on the coolant gauge is very hot. At 240 it's just starting to move to the right of center, at 3/4 I would guess 245 to 250. I have a separate coolant temp sensor and gauge so I can see it in real time and have checked it with the pcm obd2 value and they match up really well. Also don't expect much of a difference with the oil cooler at least on the stock gauge since oil temp is inferred based on coolant temp and a model. It should help coolant a little though so you will still see a small change. I also have an oil temp sensor and now with the mishimoto cooler it's way off. I still see 280ish oil when it's really 240 to 250.

 

I've got the radiator just waiting for the crash bar to get here. We're going to be building guides to insure air gets from the the nose to the radiator with no place to go. Doesn't matter how good the radiator is if you can't get the air to it and through it. We're also looking a Seibon vented hood to reduce air pressure behind the radiator. Finally, I'll probably pull off the baffle doors on the fan shroud. I'm not convinced all of the full open at speed.

 

cooling



Check my Alternative Cooling Option thread, it has data now.

 

It's 120*F outside right now. Took this this morning when it was cool out, 112*.

 

On shared oil cooler route, the very hot oil ( upwards of 300*F ) will overwhelm radiator and its coolant.

Only solution is dedicated oil cooler.

Thermostatic sandwich plate + front mount cooler ( Earl has many sizes available )

I'm not sure I understand what you were trying to say? We already have addressed oil coolers and they help keep overall temps down but it's no enough...

Did you remove the AGS assembly, or just take out the guts of it that open and close?

 

AGS was completely removed. I'll be adding the Mishimoto oil cooler for this weekend- it'll be interesting to see what both do on a completely stock car at High Plains Raceway with temps in the 90's.

 

Probably a big cause of the over heating. You need it sealed off so all the air going through the grills goes through the coolers, not around it. Look at some race car ducting, if air is going through the grill it is going through the radiator. It's 100% sealed up.

 

Hey everyone-

So Installed the Mishimoto oil cooler with their aluminum radiator. Temperatures at the track were in the 80's, very low humidity at HPR. The coolant temp's hovered right around the 210-220 range (according to the stock high-tech temp gauge on the car) and the oil temps went straight to the 260-270 range. I checked oil level, install, etc, and everything looks correct. Is anyone else having results like this? There was no difference whatsoever in oil temps, and that was not an inexpensive purchase. I had all the factory shrouds in place as well.

Any ideas? Or is this about right? It was the thermostatic version, so could the thermostat not be working correctly? (It has the stock one in it, 185 degrees)

 

The stock gauge only uses coolant temp and a model in the PCM to estimate oil temps, so other than the radiators effect on coolant temps you won't really see an oil temp difference. I have an actual gauge on the Mishi Cooler sandwich plate and it does help, but not as much as I had hoped. With the cooler, shaved grill and custom shrouding, I still saw 260+ oil temps on an 85 degree day. This is better than the 300 degree temps some have seen on track (stock gauge). My stock oil gauge was reading much higher than my actual gauge though so when it was 250-260 the stock gauge was 270-280+. If you have an OBD2 logger, the coolant is measured and pretty accurate, but hard to really see anything from the stock gauge which sits in the middle from about 120-230F. I also added an extra coolant temp sensor and gauge and confirmed it matches the OBD value very well. I just wanted to be able to easily see it in real time on track. If you actually log data and see 210-220 on track on an 85 degree day, I would call that a huge success. I need to setup my go pro for a helmet cam at my next event so the oil temp gauge can be seen/"logged" as well.

See my build thread http://www.focusst.org/forum/focus-...orum/focus-st-builds/48131-danmad32-s-daily-driver-track-day-machine-build.html and shrouding how-to for info on my setup and videos with data. http://www.focusst.org/forum/focus-...ocus-st-guides/49583-diy-radiator-shroud-w-shaved-grill-2013-2014-focus-st.html

 

Are the readings for oil and coolant temp accurate on the Accessport for live data?

(I sure miss my old BMW 325- I could drive the crap out of that thing on the track all day long with little to no overheating issues...sigh...)

 

Accessport coolant temp is accurate. The oil temp it reads is just the modeled value the computer uses for the gauge in the car, but there is no actual sensor and no way for the model to know you have an oil cooler. To get a real oil temp you need to add an actual sensor and gauge.

 

let me know how that eBay thermostat works out for you.

 

Was that for me?

 

Just installed the crash bar and radiator yesterday. It took over 10 weeks for the crash bar to come in. I still need to build guides and replace the oil cooler with a 19 row. Vented hood is still in the works

 

Where will the IC bolt up to?

 

Depending on you intercooler you may have fab up some brackets. The bottom attached to the lower core support the top attached to to slots on the radiator

 

 

Nice!! Who made the crash bar?

 

Dead hook Motorsports. 10 week lead time for me

 

Nice TIG welds.

 

Nice, custom order?

Can't wait to see how it looks once the bumper is back on.

 

Don't think its a custom order, but may be one of those things that is made to order.

Their website says in stock, so YMMV on lead time.

 

 

That's hot. You may have swayed me...

I mean you might as well, why not?! LOL. I need to sand my grill and add one of those bars. U have me convinced. And I thought I was gonna stop modding...

lol ya i am at point of no return. this thing has turned into money pit that I barely drive anymore. But i love working on it.
