On my old evo (2.0 liter w/ the green) I used 1000 cc injectors & they didn't have much left.

on my new evo (2.3 w/ green) I went w/ 1200's luckily because they were about maxed as well-car made 462whp/500 ft lbs at 29 psi

I am making almost as much power as I did on C-16

It costs around 3.50/gallon here now vs. 4.25 for 93 so it is well worth it to me & we have many stations in the area

Downside my old car w/ the AEM EMS it took about 3-5 times to get it started in 50-70 degree weather & that was in the spring w/ winter blend closer to 70

The new car w/ the AEM EMS only takes 1-2 cranks so far w/ closer to 85

 

Fast Frank-

What did you do differently between the two starting situations on the AEM? I am doing an AEM with my Green as well...

-E

 

I'm not sure that anything was done differently, same tuner same basic mods etc..

I may have had an issue w/ my old EMS?

 

Was asking because I know sometimes a custom trigger wheel helps start up and wasn't sure if you had one.

I doubt anything was wrong with your old one. It is VERY common for the AEM to act that way on the Evos on the stock trigger wheels.

Wanted to add some info..
Let's see if a single pump is good for the green's airflow.

Here's an AMS chart of what the 255 Walbro and its combinations and other pumps flow:



If I wanted to run 28psi that would put me approximately in the 70psi (28psi + approx 42psi of base fuel pressure)
Looks like a single Walbro flows 231 ltr/hr and as far as i know the flow should drop off more at 75psi because that's when the relief valve should open (unless you modify it), the graph doesn't look that way though... But in any case flow keeps falling.

So 231 liters/hour is
231 / 3.875 = 61 Gallons/hr
A gallon has between 5.8 to 6.5 lbs of gasoline and approx 6.6 lbs of Ethanol. Let's use 6.2
61 x 6.2 = 378 lbs/hr
Which is 378 / 60 = 6.3 lbs/min

So it's capable of 6.3lbs/min of fuel flow at 28psi.
And if let's say we want to see 7.6AFR (0.77 lambda or 11.4 on your gasoline configured wideband) it would be good for:
6.3 x 7.6 = 48 lbs/min air

Plus/Minus of fuel flow on the actual life application and it looks like theoretically it's right on the edge for the green turbo. Basically it can work on one. For maxing it out though, dual pump set-up will be better.

Just some numbers to back up what I've been saying all along I guess

 

Nice writeup. Lots of good info here.

 

Gained 56 max hp and 16 ft-lbs of torque on E85 vs 91+50% meth. Both tunes were done consecutively on the same dyno at Harman Motive in Torrance, CA. Huge thumbs up to Dan H and Scott B! The quality of their work and tuning is top notch. Quality of work and customer service is the best I've had in SoCal.

E85 - 376 hp & 357 ft-lbs tq
91+ 50% meth - 320 hp & 341 ft-lbs tq

For reference: was told that the new GTR did 405 hp on the same dyno

I was amazed how smooth the E85's hp and torque curves... The car is my DD and a blast for street driving.

Mellon's evogreen DLL 93 octane 26psi
***

Hey I just stumbled upon this thread while dreaming about e-85 coming to my area and I figured there would be more power with the green setup. Are you pushing the tune very hard? Maybe I'm just expecting too much from E-85 or it's just a difference in DLL settings. I'm about 300ft above sea level but don't do any SAE correction and use a conservative 165lbs for the driver weight for what it's worth. IIRC DLL was more like 395-405 in the summer heat and humidity.

I don't have a green anymore, stepped up to a HTA 35R but this was one of the last DLL's I did before the swap.

mods at the time were:
93 octane
26psi spike (tapering horribly as they do)
hks 280 cams
br deluxe fmic and pipes
br 3" turbo back, test pipe and bullet muffler
br ported stock exhaust mani
ss 02 housing
my tuning of course

I know it's not a good idea to compare DLL from car to car but it's all I have. I did trap ~ 118 with the green on 93 octane fwiw. If you have one I could run your log file through DLL to try to reduce the variables.

It does look the the 3500-4000rpm torque is way better on e-85, likely because you can run significantly more timing there.

 

You know as well as I, comparing dyno numbers between cars isn't always a good idea. Comparing DLL's is even worse. There are just TOO many variables. So if I were you i wouldn't be paying too much attention to the differences between your graph and mine. It's oranges and apples...

You will definitely pick power by going from premium to E85. You may also get faster spool-up, which i'm sure you'll appreciate with a HTA35r.

I picked up ~40-50whp/tq by switching to E85 on green, that's what matters!

 

I agree there's lots of room for errors with the variables. I can't wait for that e-85 to hit the Memphis area...I did some research and found out it's across the river in Arkansas but that's still a bit too far to drive unless I had a pickup truck with 55gallon drums

 

E-85 has convinced me to upgrade to a FP Red intstead of a 35R HTA like I was planning to do in the future. I currently run a Green and will extract as much from E-85 as I can. Adios 680cc, hello 1000cc

 

I'm waiting for some real spool-up numbers for Red. If it spools (to 28-30psi) before 5000 in 3rd gear, it may be the ticket!

 

churchja, as I said in my PM but just have to say again here, I can't get over how great your dyno graph curves look. If there has ever been an example of a FUN looking dyno graph that speaks volumes for powerband > peak numbers, that's it.
I also really appreciate the true back-to back comparison with meth. If I ever upgrade, I think between you and Mplspilot's results, I know exactly what I want. Congratulations and thanks again for sharing.

 

Red + E85 does sound like it might be a slick combo.
