Lol how can a car go lean if the pump isnt pumping It might see a stupid lean AFR for a split second before all the rail pressure is gone and there isnt enough fuel being sprayed to even ignite.

Its going to use whatever pressure is left in the rail and then shut off, now a pump that is getting weak is a little different, but every single one of us takes that risk.


IMO using E85 over a Meth Kit is more reliable, less aftermarket **** to fail, less worry and less variables, less wiring, less clutter etc etc.

Spray Meth it doesnt matter to me, you will find its far from popular in the Honda crowd.

 

Meth is fun until your pump either slows down the cycling (internal pressure regulators suck), or the pump fails, or the nozzle clogs.

K.I.S.S.

Choose a fuel, and use it.

Can someone chime in on WHY methanol has better cooling properties than ETOH? Heres my stab at it. If you look at the chemical structure of both molecules, Ethanol has a higher boiling point mainly becuase it has one more carbon atom and obviously 3 more H atoms. Since the boiling point is lower for methanol, its rate of vaporization to the gaseous phase (evaporation, and as we all know evaporation is a cooling process) is faster than ethanol (ETOH) and therefore exhibits a better cooling effect.

 

Nice

Methanol and Ethanol are very different, dont let the similarities in the name confuse you.

Methanol will make you cry if the fumes get blown in your face, Ethanol definately will not, its got a sweet smell to it.

It definately has cooling properties though (feels very cool if you pour it on your hand, similar to denatured alcohol) and supposively only burns 200deg hotter than Methanol, I know my EGT's went down vs when I was running Gas.

 

lol i was gonna start a thread like this i guess im a bit late

 

Depending on what ecu setup you are using, could you not set it up so if the ecu sees IAT that are high enough to know your meth kit is failing, then it backs off the boost, I am sure you could do it with the aem ems, but I am not sure about the other issues.

 

There's a lot of fantastic discussion of various mixtures on this page, including using NitroMethane. . .

Seems like direct port might be a good idea if you were going to pump in a bunch of Nitro though! Heh heh. . .

 

Not a bad idea, but unfortunately the stock IAT responds extremely slow.... so by the time the ECU picks up on it...... its probably too late.

You would be better off using an external pressure sensor or a hobb's switch if your ECU can be setup for it (AEM etc)

 

I'd say it depends on the availability of E85 and how much you drive. I run water/meth, which I am happy with, but the E85 gas station is 15 minutes away. I drive a fair amount, so that'd become a pain after a while.

When it comes down to it, i'd rather be running E85 than water/meth, but water/meth is much easier for me to refill.

 

Thanks, Thats what 120k of college debt will do for ya, and i still dont know anything. Hows the car coming? Dan and I are hopefully finishing up my POS soon.

 

Car is coming slowits a bare shell ATM I am just stacking parts right now, I have so much stuff still to buy it depresses me to even think about it. Still need the front end, cage, shortblock and paint before I can even start to reassemble....lol I think I went a little too far this go around but I am hoping to fall into some $$$ real soon.

With the release of the new ID2000's you better believe I will have a 4Bar map's worth of a street tune....lmfao

 

haha, tell me about it, **** adds up real quick, especially the nickle and dime stuff, really rediculous when you think about it. Im hopin to make it home soon maybe make a trip out to delmar/cecil.

 

cooling properties are all about absorbing BTUs (a btu is the amount of energy it takes to raise 1 lb of water 1 degree). just as an example lets say that we're using water to cool. if it starts out around 100 degrees under your hood then it would take 112 BTUs just to get it to its boiling point, it takes 970 BTUs to change teh state of water from liquid to gas, then once it becomes steam it expans 1700 times (making it take 1700 BTUs to raise 1 pound of steam 1 degree fareinheit.) anyway a substance with a lower boiliing point will absorb more BTUs faster because of the expansion of hte surface area. the boiling point for ethanol is 173 F while the boiling point for methanol is only 148 F.

also the two substances release different amounts of BTUs when burned. 1 gallon of meth will release 62800 BTUs while 1 gallon of ethanol will release 84400. less BTUs released=less heat.

 

e85 depends if you gona daily it. i dont know how many gas stations that carry it in you area, but i would hate to have to drive all over jus to fill up

 

true

I'm lucky,the nearest station that carries it is a 3 min drive from my house,anywhere in the city or outside i'm always +/- 10-15 mins away from somewhere that has it.

Simple solution to that though,get any decent ems that can do dual maps and hook it to a switch.1 map for gas 1 map for e85.Plenty of people do that now for race gas tunes.

 

can e85 be used on turbo cars? i was planning to buy the aem kit but should i save my $? and look into e85
