I cringe when I see people using their intercoolers and radiators.

 

nope not alone

 

looks like RDU is still an issue

Weak sauce.

 

Hard for me to imagine GKN is going to allow "more". They're the experts and the RDU capacity and durability are set. Ford's desire for less understeer would necessarily eat up some of that cushion that the RDU would have in a less sporting application. Ford's assertions that they beefed up the unit were shot down in separate interviews by the head of gkn powertrains.

Slapping on big aftermarket coolers are your only option.

 

I have an interesting data point.

Yesterday at a local autocross I had a national level driver (trophied at multiple prosolos and tours this season with a Focus RS in BS and will likely trophy at the nationals this Sept) drive my minimally prepped (B-Street) Evo X, after he drove a friend's Focus RS on the course (he doesn't own a RS anymore).

He ran a 44.3 in the RS and then a 43.7 in my X.

He commented that while my X doesn't have as much on-throttle rotation as the RS, it is much easier to drive and more composed. Mind you, he has never autocrossed an Evo X before and would likely have gone even faster if he were more used to the car, as opposed to the Focus RS that he had been actively autocrossing the entire season.

The RS has 245 RE71Rs on 8 inch rims. My Evo X has 265 RE71Rs on 8.5 inch rims with revalved MR Bilsteins and CIRO front sway bar brackets.

 

I wouldn't doubt a modded Evo X drives better than a stock RS (I assume stock as I don't see much aftermarket support, at this time).

 

A modded Evo X with wider tires, wider wheels and an upgraded suspension.

**** while we're at it, let's toss a fully prepped CSP Miata in there and compare it to a stock RS.

 

Did you even read my post? smh

 

Yes, and from what I can see, your Evo had wider tires, wider wheels, and a modified suspension.

 

OEM Evo 10 wheels are 8.5.

So it leaves wider aftermarket tires (but same brand as RS) and revalved OEM bilsteins. I would hardly call that an unfair fight but whatever..

 

Enough to explain a 0.6 second time difference.

 

Let me add a bit of clarification.

CIRO brackets are a set of adjustable sway bar endlinks that is supposed to stiffen the front sway bar a minute 15%. I still have OEM sway bar. It makes almost no difference, certainly not enough to change tire rollover amount.

My Bilsteins are off a 2014 MR and were revalved by Bilstein USA. In all honesty it is a very crappy revalve (no changes to damping forces under 5 ips and unreasonable amount of forces added all the way up to 15 ips). I am almost convinced that all they accomplished is making high speed bumps unbearably harsh with no actual improvement in autocross performance.

In other words, my 'suspension mods' are almost feel-good mods that I did because I felt guilty (lol) about running a completely stock car. I would not have any hesitation to run a factory stock evo against my car on same tires. You guys make it sound like I was comparing an Evo with Penske triple adjustables and 12kg springs against a stock RS.

And like razorlab mentioned, the Evo X comes from the factory with wider wheels and tires so I don't see how that makes the data point invalid. Hell both cars in the video are on OEM wheels.

So idk why some of you are so quick to ridicule or dismiss it. If anything the results indicate that the performance of the two cars are close under an autocross situation in BS legal trim. But of course you are free to interprete the data however you'd like.

 

It's a data/talking point. Take the "mods" with a grain of salt. I've heard from more than a few people that for how harsh the RS rides on the street, it should be a better "racecar" on track or at autocross than what it is.

 

I wonder if the rdu was working, or if it decided to tap a nap
