...We always attempt to retain factory components when possible, especially on newer vehicles...

Thank you, thank you, THANK you.

The oil cooler dose look nice.
However I am still concerned that too much of the radiator is blocked.

We are having many 100+ degree days here and normal traffic on some of our freeways resemble a parking lot.
I am also concerned about track days as I do road race and temps can get brutal.

Has any track testing of your oil cooler been done?

By the time we get your oil cooler, radiator, with fan and shroud (if you make it).
This could be a very expensive project.

Yeah. It would be SO nice if the oil cooler alone could do the job (coupled with the stock radiator), but I'm not optimistic. Current plan includes the radiator upgrade. It's double costly for me as I'll have to have a shop do the teardown to get that thing in there.

Thanks for the input Dave! We have not conducted any track testing or high rpm testing on this particular kit. Our current data provided enough support to move forward with the project, and we have full confidence that this is going to substantially reduce fluid temperatures in a track environment. We would absolutely love to get this car on the track, I know I wouldn't mind making a few laps, but this car is still under the knife with product development. This includes components such as our exhaust system, intake system, radiator and shroud, etc. It is certainly possible we will have track data once we finish our full cooling package for this vehicle. We are getting closer to a solution.

Once we do have this data, it will certainly be posted here on the forums for evaluation. I apologize that this is not available at this time.

It is certainly possible coolant temperatures will still remain dangerously high after installing our oil cooler setup. For this, an effective radiator solution or improved bumper airflow are likely the only remedies. Overheating instances are going to vary on the vehicle, driving conditions, environment. Our goal here is to produce a full package of components that will effectively solve the FIST overheating issues. We are working as quickly as possible to develop products to keep you guys on track and out of the paddock.

Thanks

[MENTION=1848]mishimoto[/MENTION] any idea when these ship out? I'm wondering if I'll receive it before my next trackday on 9/18/15

Sorry for the lack of updates in regards to the shipping information. Our original estimated ship date was 9/11. Unfortunately, we've had a couple delays which have pushed this back slightly. Our current estimated ship date is Monday 9/21. It is possible some kits will begin shipping on Friday, however I would assume the bulk of our orders will be going out Monday. I apologize for the inconvenience guys!

Hi John:

I sent an urgent PM to you regarding shipment timing. I need you to delay shipping the product to my location per our prior PM exchanges. Please acknowledge that you guys have this set when you have a chance.

Thank you.

PM sent! All set on our end. Thanks for letting us know.

Hey guys,

Just a reminder that our kits will be shipping out early next week, which will also signify the expiration of our introductory deal. If you are still on-the-fence about picking up our kit, we would recommend getting your order in this weekend.

Let me know if you have any questions!

Thanks to all who have placed orders!

Just ordered mine. Black, non-thermostatic. Living in Miami, I see 95+ degrees daily, with 99% humidity, for the entire year. Many would consider this a "very hot climate" so that's why I chose the non-thermostatic option.

And just an FYI, stock cooing fan programming is inadequate for performance use, whereas a stage 3 tune incorporates adjustments to duty cycle percentage and activation temperature. It seems likely that any decrease in radiator cooling efficiency from blocked airflow can be compensated for by adjusting these values, i.e. running a stage 3 tune.

I see you reposted the Cooling FAN tables I provided for you yesterday in this thread where you had this question...

http://www.fiestastforum.com/forum/...on-temperature?p=112346&viewfull=1#post112346

Just some further clarification...COBB also raises Cooling Fan Duty Cycle in the STAGE 1 and uses the same values used in COBB stg2 and 3 Cooling Fan Tables ....

And these tables could probably be modified further for those running track conditions....The stock table is setup moreso to optimize mileage fuel economy....

[HR][/HR]
COBB STAGE 1,2,3 Cooling Fan Tables (Same Values)


Fan Speed DC (ECT)

"This is the base fan speed duty cycle table. Additional compensations can be applied to raise or lower these values.

Tuning Tips - The OEM values are meant for economy, bringing the DC in earlier will aid in consistent power delivery."

 

[mercdank]

Yes, thank you! ! I edited the post to give you credit.

 

[BoostBumps]

Yes, thank you!

Your Welcome!

I just wanted to provide further clarification that COBB raises and uses the same duty cycle values in the Cooling Fan Tables for their stg 1, 2, and 3 maps....

More importantly those with COBB ATR could probably modify this table further and bring on duty cycle even earlier for running track conditions....The stock table was setup moreso to optimize for fuel economy...

Adjusting the cooling tables won't make that much of a difference in performance conditions. It does help a little, but I wouldn't consider it anything more than marginal and a temporary band-aid for someone that actually tries to push their vehicle even slightly over 'normal driving'.

Indeed...However, I would think bringing on duty cycle much earlier would help somewhat but its certainly not a fix particularly for those with track intentions!

 

[dyn085]

Definitely nothing major. For the guy stuck in stop-and-go traffic or drag-step racing it's great, but that's about it.

I don't consider stop-and-go or drag strip racing to be 'performance use' because loads are low or only really high for about 15 seconds. Anyone that is actually pushing their car for an extended period of time, even for something as relatively short as and auto-x or a mountain run, definitely wants to change hardware because even the OTS tune changes are ineffective in those conditions. I would probably opt for the radiator over the oil cooler first, but maybe people will accumulate some data in the future.

 

[mercdank]

Thanks for the input guys. I will be the first to admit I don't know a whole lot about exactly how well this would work, but I was just trying to think of a way to try to help the maintain normal coolant temperatures when using the Mishimoto oil cooler since it blocks some airflow to the radiator. It is likely that coolant temperature increases with the Mishi oil cooler will be greater when running a stock tune as compared to a stage 1+ tune that has adjustments to the duty cycle. I don't expect coolant temperatures to rise dramatically with the Mishi oil cooler, and it would be even nicer to know that any changes in the rate at which the coolant temperature increases can be compensated for by adjusting duty cycle and temperature activation programming.

In other words, I am trying to ascertain: Do you think that the decrease in airflow to the radiator can be offset by reprogramming of the cooling fan settings?
My goal isn't so much to increase performance, as it is to maintain efficiency, which I am hoping we can accomplish.
