I'll be switching to e85 here pretty shortly.

I absolutely agree with the 700 awhp on 16g's, not because all of a sudden the 16g's could flow more air, it's mainly because his setup plus the e85 can generate more torque with the air the 16g's can give. However, I am skeptical of the injectors used, I would think huge injectors would be needed to make that kind of power on e85.

Case in point, a local supra guy here was making around 620 whp @ 22 psi on c16 race fuel. He decided to make the jump to e85 since there's a pump local to him (and I). With no other changes to the engine, he switched to e85, and retuned his ems to account for a proper e85 afr, and ended up with over 650 whp @ 21.5 psi. He effectively gained almost 10% more power with less boost just from switching to e85. Now take full advantage of its anti-knock properties and raise the compression ratio, without even turning up the wick he could probably make another 20 or so whp just from the higher thermal efficiencies associated with higher compression ratios.....and during all this, not one hint of knock. e85 is almost a godsend.

All of these principles are applicable to twin 16g's, so now with a setup that, maxed out, might be barely pushing 630-640 awhp, can now come realistically close to pushing 700 awhp, without even touching the compression ratio.

Another note, performance-orientation aside. If one really wanted to see what e85 can do as far as gas mileage, I'm willing to bet a pretty penny that if you built a small displacement naturally aspirated engine that was built specifically to use e85, as in....super high compression ratio...to take full advantage of e85's anti-knock properties, you would probably actually end up on top of the game as far as fuel mileage (mpg) with e85 vs. pump gasoline. The efficiency boost of the sky high CR would more than offset the extra fuel generally need to produce x amount of torque. If this could be achieved, you would save money since e85 is usually about $1.00+ below the cheapest fuel on average, some places less, but some places are ALOT more cheaper. The one caveat is obviously that travelling with an e85 ONLY vehicle would be nearly impossible, not enough pumps.
