The real question is, would you notice? Is there enough performance difference that you'd be able to easily tell?

Since I drive around with my AP always on, the numbers are actually quite different. I've done some before and after datalogging and will do more today. The weather conditions are the same. Conservatively it's consistently several degrees cooler. It takes a lot to bring it meaningfully higher than ambient -- even then it cools right off.

Your point remains valid -- you won't feel it until the heat gets to a point where it affects power. That takes a lot on this little car!

It could my imagination but seeing the cooler intake temps makes me feel like it used to feel when driving in the cooler evenings.

Okay, here's one sample:

Ambient 72 deg F, 15 minutes of spirited driving, stock OE intercooler would allow intake temp to spike to 91 deg F.

Same cycle and conditions with Mountune IC peaked at 82 deg F, it took longer to get there, and was around 78 for the most part. It also cooled back to 75 once out of boost and moving at 30MPH.

Both running the 91 Cobb map on the same 91 octane fuel. Repeatable runs in my local industrial park loop.

Knock count was zero for both and -1 OAR-L. No apparent loss of power on either.

Maybe the photos don't show it well, but they look so close in size that I don't understand how the Mountune unit can perform any better. What am I missing?

Was there any drifting involved?

Much less drop in pressure! Also I'd say around10% bigger core.

Yes! Jam in, drop throttle, slide, get pointed the right way and stand on the accelerator. Rinse, repeat.

Also...I'm experimenting with lower air pressure to gain better mechanical grip from the tires.

The allotted space in the Fiesta is tight for an uprated intercooler. Anything larger (taller) would compromise the cooling system (cooling package) by blocking airflow to the radiator thereby increasing the coolant temps. Once that happens the timing is pulled and the performance suffers dramatically. Trust me when I tell you we have tested just about every configuration possible on the car coupled with all of the OE data we have access to and this is the best solution up to 230-250bhp. The stock Fiesta intercooler is about the same size as the stock Focus ST and that power unit produces significantly more power than the 1.6L. So the stock overall size is not too bad for the 1.6L Our core is tube and fine and the intercooler core has been increased in surface area and the end tanks have been reduced to allow the unit to package correctly. This then increases the cooling efficiency of the total package compared to that of the OEM unit. No drill installation. We also have an uprated intercooler pipe set coming next month. It's designed to have about a 2kPa pressure drop. The perfect complement to our MR 23(?) upgrade. It will be interesting to see the data at the track next weekend.

I have been waiting for the intercooler pipe set for the Fiesta as well.

"Before shot" while getting the FiST aligned over at WestEnd Alignment, note the visible IC:

"After shot" with new stealthier IC!

So did you map out the spot for the two hook while you had the nose off your car?

Two Hooks and I was only going to go with One behind the Lic plate maybe ...

Eh, kinda...

I want a clean setup and have some ideas. Stay tuned!

I know this is old Ken, but... What did you find with the intercooler piping upgraded at the track?
