Want more pump gas numbers-->check this thread out.
For the benefit of those who may be unaware, since E85 consumption is roughly 40% greater than gasoline, that works out to around $3.43/gallon gasoline equivalent. Hopefully it will eventually become cheaper to use E85, but as for now, it isn't the case (unfortunately).

I'm not arguing that. I'm just pointing that out for those who already whine about the cost of fuel, and that for reasons of price and availability (or rather, the lack thereof), one has to consider such things where everyday usage is concerned.
^Very true. Now can somebody answer my question!!
How reliable will the car be on e85 with stock fuel lines etc? Bigger injectors, check! Bigger fuel pump, check! What else would you need to make this system work properly. Fuel rails? Fuel pressure regulator? Thanks!

Since E85 requires 40% more volume than the gasoline equivalent, injectors and fuel pump will need to be sized accordingly. A larger rail is cheap enough, and I believe the factory lines are fine for most applications.
For example, a FP Green car using 650cc injectors and a single Walbro should consider 1000cc and possibly a dual pump arrangement. A GT35R car using 850cc should use 1200cc and a dual pump arrangement. Etc., et al.

Such a setup is limited only by injector, not pump capacity.
E85 and gasoline have almost identical s.g., so they are the same for all practical purposes. Stoich for E85 is 9.77:1, which is ~36% greater than gasoline on a mass basis.
1000cc is ~95 lb/hr, which given a conservative BSFC of 0.55 lb/hr/hp works out to be ~173 bhp/injector, or 692 bhp in total. Divide that by 1.36, and we get ~509 bhp.
In reality, that flow rate equates to 80-85% duty, and the difference in Dynojet figures from bhp decreases as the power rises, so we should be able to get ~500whp or so out of those 1000cc injectors on E85.

Awesome, lets hope for the best eh? I think MalibuJack is about to start playing with e85 and there is a guy with the username robertinaustin that is already using it unfortunately with no dynoplots or anything of the like.
I'm torn as to what to use for a race gas now.... C16 is sweet but just so damn expensive...... any good"deals" out there in the 105-115 octane range?
s.g=specific gravity correct?
-still learning

"Pump gas" or "pump fuel" carries the default connotation of 93-94 octane gasoline.
E85 should be referred to simply as "E85", regardless if it comes from a pump or a dixie cup.
Anyone who deliberately attempts to mislead forum members by obfuscating the two is lower than manure, and deserves to have their account suspended.

I am using C 16 at 11.75 per gallon now - with E 85 my fuel cost is cut significantly
E 85 for turbo cars is not targeted at the buying the gas at cosco crew

I dont want to wax overly political but it seems that the major oil companies own our government
The significance of the price of E85 really has little to do with us, but we are at the mercy of the desires of every other consumer (99+% of the buying public), and the pricing affects them. If the price is such that it's cheaper than regular gasoline, the demand will create a need for more flex fuel vehicles, increased production of E85, and naturally, nation-wide distribution. Unless or until that happens, it will remain mostly a sparsely distributed, speciality product, simply because people will use what's cheapest.
I'd love to see the day when I can quit gasoline altogether, but it just won't happen unless/until the price drops.

I can't speak for the rest of the US - but I would use E 85 where available just to help curb dependance on foriegn oil and help the environement
Brazil has the right idea on fuel and its a shame that we (USA) cant produce ethanol in reasonable amounts
I believe in free open market ecomony - however, the government must provide incentives and regulations as needed to move big business in the right direction
Props for the terminator in CA for requiring 10% ethanol in all CA fuel
Too bad the CA is so weak in other respects
