Last Sunday I took the Fiesta to button willow for its first track event.
My track car is my 91 hardtop mr2 gen3 turbo(330whp). And i have never tracked a FF before
Drove my buddies FFs before but only for one or two hot laps just for giggles.

Let me just start by saying this car was built right! Feels alittle weird on higher speed corners. Pretty sure a stiffer sway bar would make the car feel more stable but the stock suspension is great. All the kids I track with own integras, civics, and some BMW. Their cars have years of tuning for the track and talk a little mess about my Fist. That all ended when they couldnt keep up with my car in corners. My fastest time was 2.16, in 100 degree weather. I think on this setup I could break into 2:10s

The only bad thing and reason why I didn't was because the car would overheat after one hot lap so I would have to pit to let the temps cool. My AP was reading temps exceeding 235. I blame the small radiator and single fan. Th IC blocking most flow also doesn help. It was a hot day at button willow with temps of 100 but I don't think a car should ever over heat if brand new and proper coolant. My 91 mr2 has never overheated, So this was a little upsetting. I would of thought twice befor buying it if I would have known of this issue.

Another issue that happens my first two sessions was my IC coupler kept blowing off. This was when the day was a lot cooler (80 degrees) so I put a t-bolt th second time and the issue stopped, but my next session outside temps were 100.

The mods on my st is just full bolt ons and tune to open up the car a little.
Levels FIC, Cobb ap, fswerks intak, catless dp, mrt CBE.
Stock tires and wheels.

I did! That's a lot for just a radiator tho. Idk if I can wait until then. Going to buy a Toyo or other brand radiator and just tig weld it to fit. It will be way cheaper, unless the 350 sale comes out soon.

Factory stock the Radiator is adequate. You have added mods and are upset that the OEM radiator isnt able to keep up makes no sense. Your producing more HP and Tq now.

Great photos. I agree with re-rx7, more power means you are working the engine much harder and probably contributing to your cooling issues.

My mr2 has 100 more hp and the stock cooling was more than enough. But I just guess that the FiST oem cooling, cheap lol

Again ignorance. Comparing one cars cooling system to anothers is just complete non-sense. My Rx7 has 200 more and is on stock rad. You fail to take in space considerations, air flow, and yes even cost. The Mr2 when it was being built was not a cheap car by any means. Mr2 were awful handling cars if memory serves me correct. I also wonder if that MR2 has AC.

So rad!

I was thinking of going but decided to hold off.

2:13 on stock tires!!! That's fast.

Get that video together!

:D

I would think the fiesta ST has an "over boost protection" to protect it from over heating...

We are making 200+ wheel torque from a 1.6 liter engine that is running 11:1 compression and 20 pounds of boost from the factory.

Most 90's turbo cars ran 7-12 psi with 9:1 compression and 2.0/ 3.0 liter engines etc.

This car is running everything on "edge" as efficient as possible for fuel efficiency and performance...so when we add a tune without upgrading cooling.... it gets hot.

I love it, modern technology!

It's actually 10.0:1. Not sure why the specs on Fords website are wrong. I think they just copied it over from the non turbo column.

The actual Ford tech doc for the 1.6T Ecoboost lists 10.0:1 which makes more sense.

High-output 1.6-liter GTDI EcoBoost? I-4
3.11 x 3.20 in./79.0 x 81.4 mm
10.0:1

The actual Ford tech doc for the 1.6T Ecoboost lists 10.01:1 which makes more sense.

Oh wow, that's good to know and makes more sense now!

The mr2 also has like 5 gallons of coolant lol
But I still don't understand why our cooling system is so shity. The mr2 handles pretty good. It's not st, but can't say it handles awful. Mr2s have a/c. As did mine. And comparing two cars is not non-sense. Designed differently yes, but discussing pros n cons and parts that need upgrading and the others that don't. Mr2 is just an extremely old car and for a 2014 vechile to have technology and still over heat is just amusing to see.

My mr2 is running 18lbs on a td06 but that makes sense and I know for a fact I need cooling upgrade. How I like to upgrade my cars is ems, fuel, cooling and then turbo.

Didnt expect bolt ons to upset the car this much. Now time to talk to 2j and see what they think the next upgrades should be. My tuner already adjusted my tune.
