E85 vs 93 vs Spark vs Boost
If you want a solid 850rwhp go straight to a F1A especially for a 416. You say there are no fuel upgrades but there are people making big power on C7's and have been for a while. I'm sure you can get a flex fuel kit from Dsteck so you can run e85 and pump, a set of ID1300s or the new 1700s, and maybe hit up Matt at FSP or Vengeance to see what fuel upgrades they offer. Meth is a great option and low maintenance. Hell FSP just made this on 93 and meth: http://www.corvetteforum.com/forums/...p-843rwtq.html

Makes more sense now. With that said i think 12.1:1 is drastically overkill. If it where my car it would never see 93. With your fuel limitations you might want to look into a blend such as E50/70. You can achieve the same knock protection as E85 with far less fuel demand.

I know you said your not interested in running a cam but Tick Performance just built a cammed 5.3 DI Silverado and made 680RWHP through an unlocked converter. They said that they thought they had enough fuel for well over 700RWHP. It might not be the answer you are looking for, and its not an apples to apples comparison, but I'll bet if you called them they would have some insight into what the system could do. Tick posted the results on Facebook if you want to find it.
My friend also just picked up his C7 that Lingenfelter did some work on. They put a supercharger on it and reworked the heads, and put the Z06 fuel pump and injectors on and it made 608RWHP. I don't know what they did as far as cam, but I'm sure they left plenty of head room in the fuel system just to be safe, since they put a 3 year warranty on the engine.
I usually run Gen3/4 engines at ~24-25 degrees at full throttle NA (unless the compression is really high then I run less)...seems to be the best power, so yeah, 12 PSI on 93 would probably take 12 degrees...I honestly don't know what would make more power though, 93 at 12 PSI and 12 degrees or E85 at only 9 PSI...but I will say E85 at 9 PSI will take more than 15 degrees...I'd run 93 at 9 PSI and 15-16 degrees, I'd add probably 4-5 degrees of timing to that on E85.

Verdad Gallardo I can't get E85 at local stations...have to order it by the drum or go WAY out of my way to fill the tank with it (like close to an hour out of my way, onto a toll highway because it's only sold at a gas station inside a rest stop, which I then have to travel ~10 miles to an exit from to turn around and pay a second toll to come home)...so I always build my stuff to run on 93...I can get that everywhere.

I have E85 right down the street....it's looking like the E50 blend will be the solution, easy to achieve with the DSteck Flex Fuel Kit, I am already running full E85 now.
I would love to size the blower for 850rwhp @ 6300 RPMs but I'm worried about running out of fuel on E85 even with Z06 fuel system. However, at E50 I could get a lot closer and may just limit RPMs if I run out of fuel until I figure out how to get more.
