^ they have to be treated or fuel specific?

 

This is from the thread on the walbro 485

 

Hmm never thought about that...so would you get rid of your Aeromotive then?

 

yea thats what i thought, they need to be treated or it eats up all the orings n what not inside, on your pump and injectors

 

eh i think that settles it, ill just stick to 91 for now.

 

a good article from ID on the subject btw

Good info.

 

I'll just say it short and quick I don't believe in e85 (down the road I do however think it's our future fuel). Eventually it does impact your engine life, and does over time wash walls... ruin rings etc.
Some people argue that on a built performance motor, the thing's going to let go before that ever happens anyway (which I agree, this is true) but when I spend thousands on thousands to do things as best I can, I feel running e85 is against my principles. I say that knowing the amount of timing blah blah blah you can add, I just don't believe in it... Don't even get me started on the economical ethics of it either.

Proof is in the pudding though and e85 is pretty much dirt cheap every day race gas... If you want to run it, I can't knock you (HAH!) but I fundamentally disagree with it.

/endrant
Dik go pick up a good water meth kit, and set it up CORRECTLY. Then add some race gas

 

I don't think e85 will significantly reduce the lifespan of fuel pumps. Look at the walbro 255. They haven't changed it and people are running them with no problems. Same with bosch. They haven't changed their fuel pumps and I know quite a few people running 044's on e85. DSM guys run them all the time. I think it's just a CYA because they know eventually their fuel pumps fail and they can now blame it on something so they don't look bad.

So if it's shortening the life of these fuel pumps then these fuel pumps must last forever. The evo and dsm guys have been running e85 on these "standard" pumps. On that same topic some of these guys are at a decade or just shy of a decade without adverse affects on their engines with e85.

 

Yeah lots of people run it and it seems to be fine, but im at this point anti e85 pro water!

 

If i was going to do a meth kit, i would only do water injection. Hrmmm....

 

Well you're in the same boat as me. Pure water is awesome

 

it might work well but if you are worried about washing cylinders there are far more cylinders washed with water injection verses e85 fuel. I've actually never heard of it on a properly tuned e85 vehicle and I hear about water injection causing it quite a bit in both import and domestics.

Plus the amount of water you need to inject to get the same cooling effect as e85 would definitely put a person in the range of washing the cylinders or hydrolocking the engine. If not then you would see dyno numbers from cars with water injection near e85 and it's not even close.

 

I have no idea what to do thanks everyone

 

I've heard about it from my local machinist.

You've read my newest link in the water injection calculator thread right?

the amount of water you need for cooling effect is very minimal. You just want to run enough to squelch all knock basically. So you add air and timing until things even out. You run very little. Like on my 1000hp setting, I'll be running approx 740cc off the pump... not sure what I'll be doing for nozzels but that's not very much considering thats calculated for an overkill of fuel flow on 1200cc injectors.
Water doesn't wash walls like alcohol does, or attack rings the same way. Besides that it cleans the valves and has been shown to have improved head/valve cooling.

Beyond that, some very very very badass 7-8 second domestics on the domestic boards swear by 100% water. (Speaking of which I need to hunt down a thread where they were switching to 100% water, the guys were going to post data logs etc a couple of days after i found the thread)

I mean binder you're a doctor right? (not sure if this is right)
You took chemistry and understand the whole latent energy deal. Water has the highest energy absorption of any liquid known to man by MILES, simply because it doesn't change chemical structure when it goes through phase changes. E85 can run plenty cool but nothing compares to water.
Especially when we look at how the molecules arrange when benzine and h2o are mixed in air/in the combustion chamber (they line up really nicely, not sure the exact number of benzine molecules are in a row then 1 h2o then a bunch of benzine) acts as a fantastic cold spot for heat to attack. I won't thread jack but it's awesome stuff, just need to set it up right.

 

**** the 91 i'm just going to run 100% water.

 

fck ya ****.

get some sick *** custom rods made too:

 

Eeeeeeekkkkkkkk

 

i hear if the rods are bent it makes it less work for the motor

 

I heard honda's f1 cars have a second stage vtec, that bends the rods different angles for variable compression too. But it's just a knock off from ferrari.
