Hello all! I'm SPOOLISH. Its awesome to be among the beginning of a huge car scene that's in its infancy!! Anyways, I've come across a lot of information on the RS that excites me. I have found a mustang ecoboost online that makes 500hp on ALL STOCK INTERNALS. The car made the power with a 5858 turbo and some other supporting mods. This is really exciting because the focus rs has a better engine and a bigger turbo stock, well, not bigger than the 5858 lol. Now, we don't know what the stock turbo can do just yet but I think its safe to say the engine is very capable of 500hp safely and reliably.

So to get to that 500 hp would it just take some tuning? No need to add anything else to it?
I highly doubt that. There's no way of knowing what we can get out of the car untill we have more information. Or, better yet actually have the car to play with! At this point we know the RS has a better made engine than the mustang so handling 500hp should be stupid easy. My guess would be (without knowing the size of the stock turbo or how much stock boost is) the car will be capable of 80hp+ over stock on stock turbo without losing efficiency. Its direct injected so who knows the issues down the road. Coaked valves for one, like the LNF version of the cobalt ss, is probable. First mod should be PCV fix. I have a feeling its going to be an issue. I see no reason why the stock turbo wouldn't be capable of pushing the RS over 400hp. With E85 probably more like 420-430hp stock turbo.
hmm i wonder if its going to have more lag then the mustang. "added a new low inertia twin scroll turbocharger with a larger compressor wheel than what is found on the 2015 Ford Mustang EcoBoost." The Mustang already has a low interia twin scroll... sounds like they went for a larger compressor for more boost, which would then make sense why they added more components to mitigate heat
That has me wondering what it's going to be like driving out an hour to the track, ripping it around the track for the better part of the day and then driving back.
