200whp for ~$1000

But it was much closer to knock limit and far more sensitive to heatsoak and fuel quality. So with fewer mods and e85, the car makes 12whp more peak power (and a lot more area under the curve) and does so more comsistently and smoothly.

Nice results! Glad to see more E85 tuning out there!

Shiv-mon.... How is the noise with the headers and the stock muffler? Is it a middleground for sound between the exhaust mods you were running before and stock/stock? I'd be willing to toss headers on and ditch the nameless axelback if the sound is a decent amount louder than stock (which is too quiet w/o the sound tube). Got to keep those neighbors happy too

Thx!

I have similar mods on my car and I get anywhere from 21–25mpg, depending on how much stop-n-go traffic I get stuck in.. most of the time, it's 23-24 mpg since I drive ~70% hwy. I don't drive too aggressively, but I like to floor it when I get a clear stretch of road.

Too bad the Phantom is overpriced lol

We have E85 on every other corner here and it is currently $2.65, half a buck less than premium. But at 25% loss in fuel economy it's probably not a reasonable trade for a DD, although an attractive option for the track or a buzz up through the mountains. Just have to make sure I run out of gas on Friday's and that I don't get "addicted".

E85 is a full $.96 cheaper than Premium at the station at the end of my road. It is encouraging to hear that it is just about ready. I'm hoping to pick up an OFT in the next few months after a decent set of winter tires.

MPG Stats pulled from
http://cars.findthebest.com/l/1403/2...ru-BRZ-Limited

BRZ Fuel Tank capacity = 13.2 Gallons
E85 = $2.65
Premium = $2.65 + $0.50 = $3.10
Premium Average MPG in City = 22 MPG
E85 Average MPG in City = 22 * (1 - 0.25) = 16.5 MPG
Premium Average MPG Hwy = 30 MPG
E85 Average MPG HWY = 30 * (1 - 0.25) = 22.5
---------------------------------------
Tank of Premium = 13.2 * 3.10 = $40.92
Tank of E85 = 13.2 * $2.65 = $34.98
---------------------------------------
Price Per City Mile Premium = $40.92/(13.2 * 22) = $0.14 Per Mile
Price Per City Mile E85 = $34.98/(13.2 * 16.5) = $0.16 Per Mile
Price Per Hwy Mile Premium = $40.92/(13.2 * 30) = $0.10 Per Mile
Price Per Hwy Mile E85 = $34.98/(13.2 * 22.5) = $0.12 Per Mile
---------------------------------------

Difference on Quoted Gas Prices $0.02 Per Mile

Based on National Average Prices

E85 = 2.71
Premium = 3.59
Premium Average MPG in City = 22 MPG
E85 Average MPG in City = 22 * (1 - 0.25) = 16.5 MPG
Premium Average MPG Hwy = 30 MPG
E85 Average MPG HWY = 30 * (1 - 0.25) = 22.5

Tank of Premium = 13.2 * $3.59 = $47.39
Tank of E85 = 13.2 * $2.71 = $35.77
---------------------------------------
Price Per City Mile Premium = $47.39/(13.2 * 22) = $ 0.163 Per Mile
Price Per City Mile E85 = $35.77/(13.2 * 16.5) = $ 0.164 Per Mile
Price Per Hwy Mile Premium = $47.39/(13.2 * 30) = $ 0.119 Per Mile
Price Per Hwy Mile E85 = $35.77/(13.2 * 22.5) = $ 0.12 Per Mile
---------------------------------------

Difference on Quoted Gas Prices $0.001 Per Mile

So you may have to check your area for your price difference and you will fill up more often but in general the price difference between both seem to be pretty minimal.

based on national average the price difference was about $0.88

If the price difference is around that or greater the $0.90 you are getting virtually the same price per mile or better. I hope that helps.

Based on the post by @toekneehair adopted for NY prices and Mileage based on my driving (hitting redline ever drive at least a couple of times):

Edit: I calculated Price Per Mile Differently than above. I did Price Per Gallon divided by MPG.

BRZ Fuel Tank capacity = 13.2 Gallons Average "Empty" Fill = 10 Gallons
E85 = $2.95
Premium = $3.91 = $3.10
Average 93 Octane Economy = 29mpg
29 - 25% = 21.75 Adjust E85 Mileage
---------------------------------------
Tank of Premium = 10 x $3.91 = $39.10
Tank of E85 = 10 * $2.95 = $29.50
---------------------------------------
Average Price Per Mile on Premium = $0.1348/Mile
Average Price Per Mile on E85 = $0.1356/Mile
---------------------------------------

Difference on Quoted Gas Prices is literally less than a cent for my driving. With a smaller difference in price, higher jump in prices, or bigger drop on efficiency it would be less worth it, but for some reason, I don't think I would drop far below 24mpg. That would bring me down to 12.12 cents per mile.

On a different note, the worst case scenario is still better than my other beloved vehicle. I get ~$0.18 - $0.20 cents per mile in my Wrangler Rubicon.

I'm running a uel catless header with the rest of the exhaust components stock and I think it sounds great. Combined with a drop in filter, snorkel mod and OFT tuning it has a neighbor pleasing sound level during idle and light acceleration/cruising. However, you go WOT and the extra exhaust noise from the removal of the primary cat along with the additional intake sound from the snorkle mod sounds aggressive without being obnoxious. Under hard acceleration especially through the mid range band it produces a hint of that deep Boxer rumble. Not loud but a louder, more refined than factory tone and sound level. I'm so content with the setup that I added some exhaust tips on the stock muffler and consider my exhaust system complete.

Do you need me to quote myself?

The Phantom ESC doesn't have an official price yet because it hasn't been released for production.

It's also the least expensive FI option available, which has been shown to give about 50 whp and 50 wtq. Estimated prices have been speculated at around $1,800... but it's still too early to tell.

So again... huh?

[forzajuve]

To answer your question... I have already been quoted and the unit itself at the time costed $1,400, not including the batteries. Also, its a sub-FI option to be more exact. It acts more like NOS than anything else, which if you're into that type of short term burst of power, to each his own. It is a nice product and I think it is a great option but I think a more fair price should be $999. For $1,400 you can stay NA, still gain 40 whp, and still spend less. Moreover, that +40 whp is at your disposal at any time, while the Phantom's is only at your disposal every charge, which only last around 1 minute. To me,@ $999 it better competes with other power options (not including full FI kits) and feels more balanced when I begin to compare options, which everyone will inevitably do.

**edited to clarify something I wrote which came out confusing to me.
