So right now I'm having thoughts of switching to E after I get my Mid lenght and some 80's. But the real question is, will I need to get something like the ZZP boost ref. setup since it takes roughly 30% more E than gas.

I did a lot of research on this for my DSM about a year ago, since where I work has E at the pump.

 

With your setup all you will need is the injectors and a tune

 

Nice, ZZP tried to tell me to run a 2.8 I would need a FP soooo I think instead of dropping pulleys I'll go E with a header DP combo with a good dyno tune. Maybe get me some DR's idk yet though.

 

i ran with a 2.7 on the m62 some have ran 2.6 with 80's inj

 

im going to be running 2.9 pulley an 60lb injectors on e85 Boosted talked to Ebristol about the topic he knows alot about it and he does tuneing so he might beable to further answer ur questions

 

ive been running a 2.8 with 80's and E for over a year with no issues.

 

Ya im sdone asking tuners who dont run e85 or talking to people outside the cobalt website about e85. All i hear is u will run ur engine bust a fuel line change oil sooner gum up injectors lose mph. Ive talked to alot of people on here and it will be fine so im taking the plunge soon.

i think i might run e85 and a 35 or 50 shot not sure yet. Our cars seem to beable to handle e85 and nos pretty good as long as u tune for it

 

You have an 05. You'll need a fuel pump to run E, but probably won't need the BRFS.

 

why would he need a fuel pump

 

05s have a weak fuel pump. If he had an 06+ he MIGHT be OK, but I don't understand why people want to cheap out when it comes to fueling. If it were my car, I wouldn't be comfortable running it on the stock pump with E85.

What I don't understand is why ZZP told him he'd need a fuel pump for a 2.8. The 05 pump is weaker, but not THAT weak. I've seen plenty of people run a 2.8 and 60s setup on an 05.

Either way, a fuel pump is only about $65 IIRC, small price to pay in relation to running the car too lean.

 

i wouldnt worry about it if i had a wideband and i assume anyone runnning e is gonna have one just watch ur afr

 

ive ran quite a few guys on 2.8s and60s with meth and they never once have had a issue!!!!!!! So if you go e just fine tune the car!!

 

most guys dont see that big of a difference on afr's with e85. If u have time look up ebristols thread. He has all his mods and dynons on 93 oct and e85 huge difference. Also he took out a stage 1 tc cobalt pretty esaily. I have 2.9 pulley and my stock FP will do the trick. Also he has a thread on e85 and nos.; Just do some resreach but u shold be fine on a 2.8 or 2.9 with 60's or 80's u wont max out ur injectors at all

 

Or op can google e85 and ect, afr will change unleess he wide band is calibrated for the ethanol blend.

 

are u saying E and 60's on a 2.8 will work? i feel like ur idc will be about 90-95%

 

The afr's that show up on your gauges shouldnt change much at all when you switch to e85, unless you change your fuel blend setting on the actual gauge. The actual sensor on the wideband (and all o2 sensors) only read stoich and how the fuel mixture is relative to stoich. I dont want to have this argument right now though because it normally makes me lose faith in every tuner on whatever site it happens on.

 

not trying to jack the thread but im just curious what your power numbers are at

 

Ebrstiol ran e85 with suppourt mods exhuast work and a e85 tune and made in the range of 280-290 wheels and 272 for tq. on a 2.9 pulley. Its all in the tune and ur mods plus what degree of safe timming u can run. What are ur other mods besides a 2.8. I can talk to ebristol for u and find out. u might need 80's for a 2.8 depending on what type of tune u run and ur setup

 

im fully bolted i have m-dub to tune me if i want to run it but not many e85 stations in this area

 

run it dude, or atleast to get mdub to tune you for e-85 so you can have an e-85 tune and a 93 tune

 

if only e85 were closer man

 

I wish i could feel ur pain. Living in wisconsin we have over 130 e85 stations troughout the state. 2 in my city alone. Also thats great becuase when Ebristol tunes me he said he woulf reflash my tune to run 93 if i ever wanteds to go back. So thats smart.

also if u did have to upgrade to 80's zzp sells em for like 175 or something in that price rang. So that plus what ur tune costs not a bad deal for all that extra hp

right now im at 260 to the wheels maybe a bit more and with that tune i can be 10hp away from 300
safely might i add

 

I meant zzp said I need a pump to run E on a 2.8. But I won't cheap out once I go for it, I'll snag my H/DP first then my injectors and pump, may go 2.8 but I need a dual pass. ZZP will be dyne tuning the car for sure. Hoping a stock clutch will hold lol, dealer is going to be putting a new 1 in under warranty soon I hope.

Ty all for the good info/imput.

 

If you can find a dealer who will do a clutch under warranty on an 05, you owe them some sexual favors.

And yeah, you'll probably need a new one, but you're better off getting an upgraded one.

 

No i am not arguing so dont think i was, there are wide band gauges out there that ned to be calibrated meaning like the aem wideband theres one... But yes most gauged will see that the mixture for ethanol blend for a stoich afr will stay 1.00 lambda.....

so no argument hre buddy!!!
