Buschur Build/Tune + BBK = One Broad Power Curve!
On the same dyno, the FP Green did not perform as well. It has already been stated that this thing will not put down numbers like the FP Red and is most at home on pump gas. I am very happy that it puts down more horsepower up top than the FP Green on my old EVO and spools better too. A full weight EVO with these dyno numbers will trap mid 120's in the quarter. What were your expectations?
Planning to be at the Shootout. Looking forward to meeting you
Probably will bring the Genesis this year though as the Magnum has an appetite for transfer cases when being drag raced 
445whp, also on a mustang dyno, similar mod path as yours.
It made 418whp, 425 tq on a 2.0L, Green, and E85 - but the spread was not as wide as on the current setup. . .

Every 110oct evo I have retuned on E85 made more power.
We recently switched over to E85 from 116 oct on our shop Time Attack Unlimited class Subaru and it made more power, at less boost.
btw, great results, the BBK is a great stock variant turbo. I recently retuned a BBK equipped Evo 8 that had a TME turbo on before, the BBK spooled only slightly slower.
You would most likely make the same power as the 116 oct tune with E85, at a much cheaper cost.

thats interesting. I would choose the green power band. More power sooner. Good bit more in the 4500-5500 range. I am only seeing a 8 HP gain with the BBK and it sacrifices too much power under curve early on. looses 15tq. But they are really close either way I would be happy with that car
~400 TQ on a MD is enough. I would absolutely trade -15tq at 4000rpm for +30HP at 7000rpm (assuming you already have a surplus of torque. . . )

One thing to consider, though, is intended use of the car. With a light EVO there is a maximum amount of torque you can use in an autocross situation. Anything above that will make the car harder to control coming out of corners. . .

Here is a vid from my old EVO with the Green. The car was basically full weight with the dyno numbers previously referenced. You can see how fun...errr wild the torque gets in a Solo application 
Good for drifting but not so much for autox.

The problem I have right now is when David checked with the fuel cell manufacturer, they were not sure the foam in my cell would play nicely with the E85. Probably will look into changing that for next season. I still have a barrel of 116 to use up
Previously, an ethanol plant was going to build near me and was willing to sponsor the car with free E99 or what ever concentration I was interested in. If that would not have fallen through, I would be running it now.
