Ethanol blends

Interesting so it can react very fast to a fresh tank of E10 that now is E35-E85? No issues with E85 (lower air flow but much higher fuel flow requirements to the engine) to maintain richness to repvent misfires?

In the US , is Ethanol added to a base fuel with an octane of lower than that rated at the pump ?
EG : for E10 91 octane fuel is the actual octane 91 or is it higher than 91 after the ethanol has been added ?
I did do a google search but couldn't find an answer to this .

If they blend it with ethanol the final mix is the octane at the pump.
They get to use crappy fuel and improve the octane # with the Ethanol 😐

Here they mix 95 with ethanol to get 98 and advertise it as 98 (your 93) .
Ya...that's basically what they do here.....they take 85 and mix in 10% to get 87....
We can get non-ethanol 94 here though......and mix that with 50% ethanol and you have my go to fuel

im new to rotary scene. are there major benefits to running e50 or higher on renesis NA motor. ideally i want to setup for flex fuel but dont want to go with stand alone ecu. this will be mostly track car. i ran e85 on my Evo. it's cheap, burns clean, and run cooler. is it worth the hassle for NA renesis. how much more power can i expect running e50-85

It will depend on a lot of variables and my car is mostly custom mods rather than off the shelf parts. I dyno’d higher on gasoline than anything I’ve seen for E85 from anyone I’d trust to provide a good number. The potential is quite significant for FI, but for NA it’s pretty much what I previously posted.

ok, ill stay with 93 pump for the first season and see how close i can get to max hp/weight ratio for the class. running a turbo car for the last 7 years, i'm spoiled with having max power from 4k to red line :D

the 8 is a somewhat a momentum car. definitely different from driving the evo. you'll never be below 4k on most tracks, but when you are IT SUCKS

Actually he stated in text at the very beginning of the thread that it dyno’d 179 rwhp before mods including the fuel change. It still doesn’t define it exactly, but if you figure in the usual expectation for the tuning and mods it more or less mirrors my general assessment.

For anyone turboed that runs a high % ethanol mixture . The omp oil cranked up is insufficient to properly lubricate the apex seals past about 10PSI .
I now run Motul micro 2T premix (150:1) as well as omp for any hard abuse situations when running an ethanol mix.
