    The problem is with the 35% according to this facebook page, you can only run e85 on stock tune or lower boost. It will not support more boost.

    I have not seen any testing on if it helps the fuel rail pressure dip i was asking rbrown about....and hes the only guy on here i know of using these right now. If it fixed this, it would be safe to run a little more boost.

    If we can make 400-450 on gt turbo on stock hpfp and be safe fueling, i dont see a point to this pump any longer.

    I did run full E85 on the 35% HPFP. If you work the wastegate table to bring boost out later in the RPM, you can run around 17-18 psi and more timing using E85. I was able to make around 400whp at 17 psi with 14* and I know it would have taken more timing but I ran out of time testing. However, you are correct, down low the 35 suffers the same fate as the stock pump with issues pumping enough fuel to support higher boost, and we know most tunes make quite a bit of boost right on the initial hit.

    @WooBoost its going to take cams to fix what you talking about...

    Everyone that was pushing to get people to buy them (ie get others to be the Guinea pigs) stopped talking about them when they realized that even with the 60% pump, you are just fighting a system at its limits in that low rpm area where the ecoboost shines.

    Not being a D. But dude why post this now when your a coyote owner. I’m very confused. I get the other posts but not this. The link comes in the instructions when customers by the pump from a Dealer.

    UWE on his page was only testing the 35% pump on stock tune last time I looked on e85. His claim was it will save owners money, however we know e85 gets far worse MPG. It's only benefit is using as race gas type aka more power, not DD.

    You're saying the 35% suffers down low like stock pump....on pump gas or e85?

    lol. It's just so many factors this is why I like to see others sort out the BS first. a pump and turbos cost the same. Turbos will provide a lot more pleasure and power, however i would need a shop to do it($$) bc im not in a location currently I can do work like that myself (although I am capable) on the other hand the pump is easier to install than changing spark plugs. To run e85 in even stock boost or mess with tables for a little more boost (menmtioned above) would require a dyno tune, turbos would as well. So if I got a pump, it would only be for 93 and bumping boost some bc i dont have a want for dyno tune unless turbos. On top of all this I commute to work everyday in traffic and a few times a month I drive a couple hundred miles away. Turbos would favor this, bc if i am going to be running 93 on turbos and pump for the benefits of each, why only get a little hp on the pump when turbos give a lot more power. On top of all that, do I even need any of those? Maybe just run 87 always bc DD. This is all the **** that goes through my head.

    Haha. I KNOW what you mean. As I've gotten older, I have learned to turn it off when I suddenly realize I'm bouncing all over the place.
    Or put another way, I just allow myself to make LESS than the best decisions. At least that way I actually make one.
