Max power without Cam/heads? with E85?
So after reading some of JJFormato's threads about E85 and the flex fuel sensor mods, etc.
It seems like 460-480whp with intake/headers/E85/tune (and maybe a ported TB/Mani) is possible... Has anyone done more? Is a cam going to be required to get over 500whp or has someone done it already and I missed it?
Thanks all!

My local dyno put a stock C7 at 415.
My car dyno'd 439 with only a tune and ported TB / intake manifold.
Now I have headers and a CAI (AFE). Haven't redyno'd yet.
I would expect ~470 and with E85, ~480-485
IMO, it will be hard to surpass 500 without a cam (NA). However, there is no driveability penalty up to that point either.

In a few weeks I plan to install
TSP Heads, bump compression to 12.1, Custom CAI, TSP LT's/no cats, E85 Flex fuel kit, ported Manifold/TB. I'm an A8 and I think 500rwhp will be possible with stock cam (only b/c of the heads/CR jump)
