Simple mods like intake and full exhaust and tuning will put this thing in the 345-360 whp range on cobbs dyno. I don't think big gains are coming from intake and exhaust being that the factory stuff must flow great to get 345 bhp to begin with. Some improvement is better than nothing tho with intake and exhaust. So add e85 and I'm sure we could be close to that majical 400 whp number. Then as montune releases cams, throttle body and other upgrades we could see 400 whp on pump gas and 450 on e85 on the stock turbo.
Clearly the 50 hp is going to come from the tuning side mainly. If what you're saying is even remotely close to being true, then a 2500 dollar turbo swap and another few hundred for tuning will solve all of this. Not really a lot of money in the grand scheme of things.I don't think ford is going to be leaving much on the table with this one. The ST saw such big gains from tuning partly because ford dialed the torque back to make it manageable, that won't be the case with the RS. The factory exhaust and intake look like they're designed to breathe pretty well out of the box as well. Not saying there won't be some room for improvement with bolt-ons, but certainly not as much as there was with the ST. If you want your RS to put down 400 hp it's going to cost you.
What does this mean?There won't be much room for improvement according to inside source over by the Impreza forums. The car will need lots of money poured into it to have good gains vs reliability
I was in the market for the ecoboost mustang. So i followed the guys on the ecoboost forums-those guys are pumping out huge gains that are reliable. Go check those forums out. Guys with tunes and exhaust are pushing 370hp 400trq. Of course, it starts to drop significantly after 5500RPM.There won't be much room for improvement according to inside source over by the Impreza forums.
