I am running 10:6:1 compression on my b16 pump gas is not doing it for me that's why i went to E85 i get more octane for a better price + E85 don't stink like gas does it smells like wine to me
.
10.6:1 is
not high compression
you can run a B16 on 91 octane with no problems at all
using a higher octane than what is required for the engine is a waste
if you cant compress it enough, it wont burn as strong or completely
this means you have a weaker combustion, and you make
LESS power
you should run your car on the lowest octane you can run without detonating
that will give you your best burn and the most power
running a grade higher as insurance if you are going to be running the engine HOT for a long time to protect against detonation is fine... but otherwise it is a complete waste
so e85 on an engine not built for it with HIGH compression or boost is going to make LESS power, and get worse mileage.... all around waste of money
if you want to run e85 and actually make power with it on an NA engine... then get your compression up around 13.5-14:1.... run a lumpy ass cam and a big injector... get it tuned by someone who knows what the fuck they are doing... and go have fun
with proper tuning you can run into the mid 12._:1 range on pump gas
high octane alone DOES NOT MAKE MORE POWER
