Hey guys i recently finished my heads cam swap on my camaro runs great perfect even without a tune ! SO here is the dilemma i need to upgrade injectors and i kinda wanna run e85 i can get deka 60lb of my buds supercharged mustang for cheap with less than 1k on them , or just pick up some red tops. Here are some Facts i have had my car for nearly 2 years and put only 3k miles on her so the whole loosing mpgs is not big for me, there is an e85 station 1 mile from my house and others within 6 mile radius so thats covered , i HAVE not gotten a tune yet so im not loosing money on a retune and it would be something different and i could pick up a few more ponies !!!!!


Camaro = fast 78 , 216/220 560/560 cam , 243 heads milled to 11:1 ,pacesetter shorties , bassani Ory to 3.5 mufflex catback, powerbond underdrive


will i see any good gains ?????? or stay non e85 ???

if you're staying normally aspirated then I say just keep it running on regular gas.

yea but if i can squeeze a at least 10hp out of it wouldnt that be worth it ???

No lol

im spending 100 more for 60lb injectors than red tops so 100 for 10hp isnt that bad lol !

can any one with e85 chime in and lay down some positive info ????

With e85 there is more maintainence to the fuel system you have to clean your injectors check your gas atthe srations to find consist e85 the fuel will deteriorate your fuel lines quicker it is worse gas mileage and not worth 10 hp lol it sounds like you want it just to say you have it

hell yea i wanna say im running e85!!! its like saying your gf is a 10 when she is really a 6 !!!
but really would like to try something different and maybe make more power !!!

At 11:1 there is no reason to run it. It's just adding more maintainence that you have to deal with. The onlyreason guys run it in high ccompression 12.x:1 and up and forced injection is because it's cheap race gas. But it seems like your mind is already set on it so hopefully there are good stations near you lol

ok then one quick question can i run red top injectors without a tune till i get a tune in a month ???

It's going to be very rich dumping all that extra fuel in it I'd run the ones you have until it's tuned

SMH...

Don't ask for advice, then argue.

E85 has nearly HALF the BTU's of gasoline, thus approximately half the fuel mileage. You will need to maintain the system better, keep a hunt on for E85, and fill up about twice as often. Will it be worth it for 10hp? Not in my opinion anyhow

I'll play devils advocate here for a sec. So far here I have seen people say its not worth it but no offers up much fact why....

Other cars with similar compression seem to pick up around 15-20whp with the timing adjustments and fuel corrections made so I'd think it comfortable to say it worth more than 10 especially with the op's mods.

Has anyone here drove and documented the mpg drop with e85? I have and it drops roughly 30% seen it on my dad's tahoe and on other cars as well. E85's stoich ratio is around 10:1 and gasoline's is around 13.8:1 this means that it should consume roughly 40% more fuel. On paper e85 looks like it will eat much mroe than the 30% I posted but then again e85 also burns much more densly than gas. When gasoline burns 60% of the burn is converted to energy and 40 is lost to heat. When e85 burns it makes 85% energy and converts only 15 to heat.

One benefit to it making more power that no one recognizes is that E85 since it burns with less heat loss, cools the intake charge much more than gasoline will so its like running in really cool weather all the time or having a badass CAI.

So with all that said if the op wants to run e85 he will need bigger injectors and likely a racetronics pump (good investment anyway). The fuel system amy or not be ok if you drove the car consistantly and ran some regu;ar gas through it before storing and every once in a while it would be probably ok. To be safe though I would probably replace the few rubber lines our vcars have which isnt a big deal

roninsonic - I argue with the advice if i stated mpg wont matter or that i will have to search for fuel stations. I definitely appreciate all the advice but when it comes down to it i wanted to see if any good gains could be made.With that said i think ill get it tuned to 91 then run e85 and see if i can gain anything , and since my tuner will only charge me 100 for re-tune and i can borrow my buds injectors it wont cost much more than just time..... I will keep you guys posted this coming month Thanks again guys !!!

Oh and just to add this logic is completely flawed. BTU's mean little unless your talking about a BBQ or home heater. All Btu's state that as the fuel burns it produces so many british thermal units of heat. Without getting into physics and gas laws it boils down to something like this. Heat DOES NOT drive an engine and the pressure from the explosion does.

The amount of BTU's created by ethanol is less than gasoline which as I said before (60% VS 85% efficiency) produces a cooler burn which is a good thing. The energy that is extracted from the reaction is less with ethanol which is why more must be burned but again it results in only a 25-30% loss in economy.

OP, sounds to me like you started a pointless thread. You asked a question, then argued when you didn't hear the answer you wanted. Stop thinking like a child and wasting everyone's mind.

Seems like you have your mind made up. If you daily drive the car I wouldn't run e85 in a na motor unless you have higher compression (exp 13:1 like my buddy's 427) . Now if you don't drive it as much than run e85 and see how it does. If I was in your shoes I wouldn't run it just my .02
