I looked into buying it by the barrel for track days. The most economical way was a station about an hour away and having them fill a fuel drum. I called and asked and they were not willing to fill a drum for me even if it was fuel rated

Well yes, but also no. Let's say you have a full tank of E85, and you drive to the track and let's say it's a really long way away. You get there with a half-tank and there's no E85 stations near-by. You fill up the rest of the tank on 93 because that's what's available. Okay, well now you have ~E45 and you're still getting massive benefits of ethanol which is way more power, cooler running engine, and more knock resistance.

Definitely up to you, but E85 is just such a big gamechanger on these cars. There's bone stock (minus tune) w/ E85 cars doing 200 whp. Is there even a single stock block NA 91/93 octane car out there doing over 200 whp? I honestly don't think so, but maybe there's like one (PTunings, though technically it was 199.5 whp). Just food for thought.

That 200whp is so dyno dependent. Delicious tuning has a video of them hitting 201whp with only E85 on a Dynojet with STD correction which seem legit until they mention it was ran in 5th gear. More often than not dyno graphs for this car and many other are done and shown in 4th gear. Well 4th was 197whp with STD correction on that dyno. Had it been in SAE it would have been around 193whp in 4th. It should also be noted that car baselined at 175whp. I think we could agree that a 20whp+ gain from E85 on a stock car is possibility but not necessarily a game changer.



Oh and Ptuning doesn't apply any correction factors to their dyno figures, I asked. It makes whatever it makes that day. They have read as high as 227whp on a FBO E85 FA20 and even 215whp with crap Borla UEL headers.

Oh yeah no doubt it depends on the dyno. In general, I think we still have more than enough data to conclude that E85 alone is worth a ton of power on these cars. In some cases, it's worth more power than FBO's on pump gas.

Just for reference: I can fit 6 of the 5-gallon jugs of E85 in the trunk of the BRZ. If I fold down the back seats, I can fit about the same amount of containers in the passenger seat and one on the floor, so I can potentially store 14-15 of the 5-gallon jugs with 75 gallons of gas plus the gas tank. Just saying.

I hope you drive with your windows down.

Well, I usually do have the windows open, but the containers are sealed. I know they seal well because the alcohol vapor can pressurize with heat enough to expand the tank and cause a hiss when opened, which is why they have a line that says, "Do not fill past this line." Plus, they are CARB compliant.

They are 75+ percent alcohol too. Ever been to a frat party?

10k rpm? I am suddenly interested!
