900 BHP in a 3.8 is comparable to 450 BHP in a 1.6.
At power levels that high in a street driven vehicle, your Fast, Cheap, Reliable question is blown out of the water, anyway. I don't care how much money you have available to spend on it, reliabiliy becomes relative in a high HP street car.
To the question of E85, and why one would want to use it, it can handle much higher combustion pressures and temperatures without detonation. It has an apparent octane level higher than some race fuels. It's reasonable to think that you could have 14:1 dynamic compression ratios while still running boost, and not get detonation with a proper tune and timing curves.

900hp/3000lb, and 450hp/2300lb. 3.33lbs per hp vs 5.11lbs per hp, it's simple math. 3.33lbs per hp will outrun 5.11lbs per hp, that's what I meant by not comparable
.
I know exactly what e85 does, and it's high octane, it's good stuff, it's just easier to use meth kit. get some low comp pistons and you won't have to worry about detonation. Back in the day I was running 18psi on 93 octane and 27psi on meth with intercooler, I blew a head gasket once I believe, but that was it, ran it that way for 3 years and 50xxx miles, the motor had 170xxx miles on it when I started modding it, to this day it still runs good in my buddies car with well over 300xxx miles on it, but he doesn't run more than 10psi though.
