2012 Civic Si 92 octane and E85 results

[VitViper]

Just got done with the 2012 Si Dagocrazy drove up for some testing. We did a 92 octane and an E85 tune right after. Using Dyno dynamics dyno in Oregon. Here are the results!

Pump gas results: 218whp/190wtq

E85 results: 225whp/200wtq

Pump gas vs E85

And of course, we love to compare to the 8th gen... pump gas vs pump gas, same dyno. The 8th gen dyno is literally my own 08 Civic Si from about 3 years ago when it had bolt ons (i/h/e).

very nice man! Added vid to the media area & linked it here for dyno sheets.

Wait... Our cars can run e85 and get more power. Will this hurt anything? Can I get more power from e85 stock and not damage anything or would some work be needed to run it

 

[KennyGS]

Any conversions needed for E85?

it's not uncommon for turbo users to run an e85 setup to create more power.

"The higher autoignition temperature of Ethanol (689 degrees F, compared to gasoline's 475 degrees F) enables E85 to be more knock-resistant and handle more boost or higher compression."

Yeah I've seen a lot of supercars as well run e85 for more power. But will my Si run e85 with no damage and generate more power?

if you're running flashpro and you have the car tuned for e85. Looks like vit gained 7hp/10tq on the e85 tune.

 

[VitViper]

Bingo, you need FlashPro, and if you are bolt on -- all you need is a set of 550cc injectors to support E85. We used Deatschwerks new 550cc injectors that they recently released (fits 8th gen RBC manifold).

 

[Bulkybear]

Ok so its not as simple as putting e85 in and gaining 10 go lol.

 

[webby]

Vit - you want to specify an injector set that you like for e85? I'm sure this will not be the only time it comes up.

 

[VitViper]

I was using the Deatschwerks EV14 Universal line injectors that they recently came out with. I will have a deeper review on the injectors soon.

What mods is he running on the pump gas set up?

 

[webby]

looks like he's running a rbc manifold with an aem intake from this post

not sure about exhaust or whatever....

 

[w00t692]

he has a downpipe as well.

 

[VitViper]

3" exhaust (Full Race I believe).
8th gen AEM CAI
RBC IM
RV6 3" catted DP

 

[boejoula]

Wait.... Rv-6 has a 3" now?

 

[VitViper]

Sorry, it's the ultimate racing 3" dp. Was a really loooonng and busy weekend

 

[Nix]

Nice stuff! Thanks vit.

 

[squiggy]

Nice stuff! Thanks vit.

How does this affect the MPGs?

 

[w00t692]

expect 20% less mpg on E85.
