E85 & tpro=500HP

E85 prices.

E-85 is 2.57 around Chicago.

What a/f ratio where you running?

Thanks

You can't compare E-85 to gasoline or even Race gas for that matter. You put E-85 in a car, use the same timing, boost, etc and change nothing but fueling and you make more power/ torque immediately. In fact E-85 is alot more forgiving than gas, so much so that you know have to worry about breaking the engine before knock occurs.

Going to bigger injectors and better fuel lines is a small price to pay to able to use the same setup and get at least 20% more power even more safely than you did before..all the while having a very clean burning engine. We all know how these cars dirty the oil quickly, anything to help that is an added plus.

No apologies to the race gas or alky guys but E-85 is the future of real power at an affordable price. Alky is affordable but the power you can make will be less period!! I know of plenty of people that have now taken their Race gas out or removed the alky injection system in lieu of E-85. Its hard to get in most places but once you run it you will see, its that simple.

TOM Did you buy chance notice how much your EGTs drooped from before without E-85??

No I didn't use a egt, and I ran AFR of 11.5

Do u have proof to back that up. A local discussion around here is not in agreement with that and also about the cost factor. The fact that U have to burn more of the E-85 as compared to straight 93 Alky negates the assumed cost savings. For example it may take 1 gallon to drive from point A to point B using 93 octane at a cost of $3.40 a gallon. That same trip using E-85 will cost u $3.43 because ur consumption of fuel will be about 1.3 gallons. (Assuming ur getting E-85 at 2.50 a gallon, 1.3 gallons=$3.43) So yes U can run higher boost, but that will require even more fuel with E85 which again cuts into the assumed savings, maybe even putting U in the red compared to 93 and alky. Those are my numbers check em out and let me know if Im wrong.

Good Point! I'd like to see some proof also.

E-85 is 105 octane. How can your car be faster on it than 114 ????

Good to hear another GN running the Corn power, it will be huge once we get 95lb and larger high Z injectors.

Even though E85 is 105 octane it does not act like that because it is an alcohol and has a much cooler physical property than gas. Many turbo shops are seeing the same results as 110 or 112 gas and some have seen the same at C16.

Good to hear there will be some in tank pumps coming out, but they will have to be really huge like 50% bigger for it to be worth while.

A couple of the things I like about E85 is that you can easily get it ( Illinois has over 150 pumps and counting ) and that you don't have to worry about the alky pump dying or not spraying alky in your car. You can run the same tune over and over again.

What kind of chip do you have to run to get more fueling out of the injector? If you are using 83# injectors, is the chip burned for 83# injectors since you have to use more E85 than premium unleaded? And have you noticed that it consumes alot more than unleaded? Awesome #'s!!!

From my research on E85 it only uses more fuel at or near WOT. If your driving around in normal driving conditions you wont notice much difference in fuel mileage.

rb66rr octane is not everything. Those of you who know me know my car ran better on 104 unleaded than it did on leaded 112 or higher. I found comparable runs on 110 leaded as I did on the unleaded. check my sig those #'s were on unleaded.

Different fuels have different burn rates, meaning you need to experiment with different octanes not just buy into all the B.S you read. (Oh I need 116 because thats what everybody else is using).

Do your own research because your probably spending way more for fuel than you need to. Only use the max octane you need to suppress knock, any higher your just wasting money.

just because one can run 25 psi and 25 deg timing , dont ASSume that the same amount of power is being made with the e-85. this same motor on 110 would make more power. im not trying to bash e-85. its a good alternative, but its not a breakthrough.

Are you sure about that, check out this thread. I would willing to do a simular experiment if someone wants to help with the cost. THIS WOULD BE FOR THE GOOD OF THE BUICK COMMUNITY! There are plenty of well respected buick guys in the chicagoland area that could take witness.

Tom what kind of mileage are U getting?

Im just trying to make sure my numbers were correct or close to itin my earlier post on this topic.

I don't now, No odometer

Doug, I know what you mean. My car hates c116!!
