EM's GT-R Refresh

Thank you for the explanation. So water separates from the fuel, however, how do you tell the difference between gas content and ethanol? Sorry if I missed something.

you don't, you use the tester to check the ethanol content of what is in the pump.

you don't, you use the tester to check the ethanol content of what is in the pump.

So, basically it's susceptible to the same issue as the "ethanol" (actually gas) sensor?

[Seer]

All it is, is a graded tube, that tests ethanol content from the pump. You fill the water to the water fill line, then the rest with "E85" when it separates it tells you what real percentage of ethanol is coming from the pump. If it's E85, it'll show 85%

My car will just make whatever it makes on pump and I'm calling it a day. That is if I ever build a motor atleast.

Plus the closest e85 station to me is I believe 35-40 minutes

Im with you bro, E85 is way to scarce around these parts and it seems as if there's always worries of various grades, etc...thus the reason why I ruled it out awhile back. I can think of easier and more dependable ways of picking up 25-35 RWHP.

25-35rwhp.

such a cute little yellow car.....

Yep, thats about what the average NA car picks up......what does the average boosted car pickup....40-50 rwhp?

I've seen gains in the 100+ whp range in a turbo car.

DSteck flex fuel sensor and a tune. Put E85 in when you can/on the way to the track and never worry about it.

Adding boost then yes I can see that but fuel/tune only the gains won't be nearly that high. Adding fuel/tune/boost then absolutely.

I've looked into it....yes $500 for the Dsteck setup and $150 for new fuel pump....and $800-1000 for injectors and probably $300-400 for fuel pump install as I've heard it's a huge pita to change then you got it.

I've already got ID1000 injectors so no worry there for me but I'd still need the fuel pump...install and the flex fuel setup and then a re-tune. If there were more E85 stations around and the fuel seemed more stable I'd probably go for it as I'm all about picking up extra power.

[JeffreyCole]

I think that's kinda the point though lol.

E85 greatly increases the knock threshold, so you lean it out to 12.5:1 (gas scale wideband), add 10 lbs of boost, and 6 degrees ignition timing.

Leaner, more boost, more aggressive timing, just like switching from pump to c16.

[ERR0RMACR0]

Yeah, e85 is mostly about running more boost. You pick up power in a bunch of different ways (as Jeff pointed out), but primarily boost is the key.

My setup is approximately a 100hp pickup on e85. I just think of it this way:

A lot of guys run octane boosters, or find 110 or whatever, this is the same thing for my car. Except my race gas is $2 a gallon lol. If there weren't 3 e85 stations within 15-20 minutes of my house, I'd just order a barrel and run it when at the track rather than all of the time.

They are placed perfect around the city for me.

One by my house, one on way to work, one on way out east and one up north.

Debating on taking the car to work today.

Sure is chilly.


BTW,

Walmart has Lucas Ethanol Treatment on the cheap.

Basically $2 a fill up to add.

Grabbing a case of it after work tomorrow.

I bought a case from Amazon a couple weeks ago for around $100. 24 5oz bottles. 5oz. treats 25gallons, but I usually just use the whole 5oz. on a fillup (19 gallons). How much is the case from Walmart?

[thedak]

With tax around $98ish

[thedak]

Hmmmm...

Case of the 12oz bottles is only $76 a case on Amazon.

[ERR0RMACR0]

I think it's a 12 case of 16oz. that you are looking at.

That's quite a deal, that works out to 192oz. total for $76

I paid $100 for 126oz. total. Then again, I pretty much bought the 5oz. case, so that I didn't have to measure or anything at the pump. Looks like I'm paying nearly double (my case is $0.76 per oz. while your case is $0.40 per oz.) for convenience...ugh, what's done is done I guess lol.

Im going from 21psi on 93 to hopefully 30psi on e85 (with new heads, bigger turbo), I better pick up more than 50whp or I'm going to put it on craiglist with thedak.
