So maybe Ford simply doesn't know their overboost function is not working as intended. Is that better or worse than simply fudging numbers a bit?

 

More speculation. Until we have an explanation, we're just putting our thumbs in our asses and claiming we found oil.

 

Evo 10 is a Evo thick skull.

 

No, owners/tuners have found that the car is not working as advertised.

 

I have some logs of the USDM Focus RS and what is happening is throttle closure, so my thoughts where correct.

It's not overboost not working, it's the other ECU fail safes coming into play. I think perhaps Ford made the first ROM rev a little too conservative for North American fuel.

Tuning will of course help, a new ROM rev from Ford is also probably inevitable.

Mitsubishi did the same thing with the Evo 10 when it first came out.

Here is a 4th gear pull showing throttle closure:

Correction, owners/tuners have dynoed the car, and been unhappy with the results. That is not the same as the car not working as advertised.

 

If it is working as intended that is even worse. Can you still claim the car has 350hp at that point?

Any aftermarket tune that "fixes" it will undoubtedly void the warranty.

Ford says, nearly permanent overboost gives 350hp. Reality says something else.

 

This is a ****ing lost cause. Fine, you're right, the out of context, no baseline dynos you have prove beyond a doubt that the RS doesn't make the power claimed. You've won; the Evo 9 is the bestest car ever made and nothing can ever touch it. Your ego is safe and unchallenged.

 

How are the baseline dynos out of context?

 

I am right. Those results are the baseline dynos. The results are in. Overboost is not working consistently. The stock RS is not making the advertised 350hp. Any questions?

 

Bench racing is lame. How do the real world numbers stack up? What do the stock 1/4 mile times look like? Skid pad #'s lap times etc, these are the things that will actually matter in the real world.

 

There is a lot of chaff in this thread so I will repost this for you.
2016 Ford Focus RS vs. 2015 Subaru WRX STI
0–30 MPH 1.5 sec vs. 1.4 sec
0–60 MPH 4.6 sec vs. 4.7 sec
0–100 MPH 12.2 sec vs. 12.0 sec
0–110 MPH 14.4 sec vs. 16.0 sec
¼-MILE @ MPH13.4 sec @ 105 vs. 13.4 sec @ 104

Almost identical results. Which makes sense with both car's dynoing at ~250whp. stock. One would expect better results from the RS if the claimed 50hp. advantage of the RS was a reality.

 

Ah thx for posting that. Well one things for sure, its certainly not revolutionary or anything.

 

...so you are this dense. Where is the baseline indicating what 250 whp means on that specific dyno?

 

I wonder why there doesn't seem to be any mfg in this platform that has the ***** to do a flexfuel setup. Now that would be something.
