Looking to switch to E85
I recently just finished up a build and could not boost over 16 psi because my brand new AEM Water/Meth controller took a crap on me. I'm tired of the trying to play the gas game and can get E85 locally. I'm curious as to the next step for E85. Here is my fuel system and turbo setup:
T04Z w/ Vmount kit
ID850 primaries and ID2000 secondaries
Aeromotive A1000 fuel pump w/ large surge tank
-10 AN hard line up to the engine bay with a -8 AN drop for the FPR and Xcessive rail for use with the Xcessive LIM.
I have only had the car on the dyno and was not impressed with the numbers. Wanting to run E85 now. I also stepped up to the Adaptronic ECU to control boost and AFRs and IDC.
How do I go about flushing the system to run E85? Is this something I can accomplish in my garage? I would imagine that I need to run upwards of ID2000 primaries as well but that is an easy swap.
What should my target AFR's be and what should my fuel pressure be? still 43.5 at idle?

What Numbers did she put out
What numbers are you looking for?
Are you running 2 850 and 4 2000 in the Xcessive LIM.
Fuel press 43 is fine, AFR all depends on the porting and timing.
Also What Apex Seals, if your running soft seals I wouldn't worry about AFR, as the leaner the engine runs the Hotter the EGT will get and soft seals don't hold to high EGT like stock,Atkins or Super seals.

you should have made around 450/460...
if not, there could be other factors with which you have to deal, otherwise you will switch to E85 and be watching the same movie.
can you post a dyno sheet? it would be helpful. zero smoothing, rpm on the X line and SAE.

I'll try to get the dyno sheet. Steve says the car sounds great and isn't missing a beat. It made 330 hp on a mustang dyno which he claims is 10-15% under other dynos. So I'm thinking it makes about 370.
Apex seals are 2mm super seals. They have held up well thus far. I won't use any soft seals because they break so easily. I'm also just running 2xID850 pri. and 2XID2000 sec.
As for numbers... I'm was trying to get over that 500 mark. I know the T04Z builds usually make between 425 and 450 with supporting mods at 1 bar so I'm kind of baffled as to what the deal is. Engine wraps to 8500 rpm without the slightest sputter. The plan was 22 psi with water/meth but the AEM controller took a ****. It's brand new out of the box and functioned properly about once. Now it won't stop throwing error codes. I have to box it up and send it back to AEM.
How do I go about cleaning the injectors and pump so I can swap to E85?

Shouldn't be bad then. I'll dump my ID850s and grab another set of ID2000s for primaries. Already have ID2000s for secondaries.
550 x 6.5 = 3575 CC/min NET of lag and IDC
3600 x 1.35 = 4860 Gross injector capacity needed
4 x 2000 = 8000 CC/min or @70% should be around 5600 CC/min gross capacity.
Is this correct on the math? I think I can even just step up to ID1300 primaries and leave my secondaries. That would be 5600 @ 86% would be about 4860 (capacity needed) and I would be able to idle and cruise a little smoother.
Is this correct on my assumptions or should I just go up to the ID2000 primaries?
Pump: Aeromotive A1000 w/ pre and post filters and large surge tank

That's good you have nice clean new lines. Did you clean the tank? What kind of filters?
Are you in an area where ethanol content varies significantly by season? If so you may want to look into tuning with a flex fuel sensor...or buying your E85 in drums.

Tank was cleaned inside and out. The filters are aeromotive pre and after pump filters. Paid high dollar for those filters.
The E85 here is sold on Hurlburt AFB so it doesn't change from season to season. It's about 35 minutes from my house. I have heard good things about the quality of their E85. A couple of big evos and sti run it.

I would suggest at least a 10 micron Filter with a SS element so the injectors dont get clogged. The fuel tank has a small drain in the bottom of it drain the gas out its to easy too do. I did it in my garage.
I'm running 4 id2000 and its a great combination on E85 I wouldn't put anything smaller if your target is 500+ whp. The -8 feed and -8 return is also done on my car but I went with dual walbro 485 in tank they work great.

The internal filter on ID2000 is 7 micron. If you want to prevent your injectors from being clogged it would be wise to run a filter element that is smaller than the injector filter. The best E85 filter currently on the market is the 6 micron fiberglass from Fuel Lab. Ive confirmed this with ID. Your 10u isn't ideal, but may suffice. What material is the element?
Other than that, you seem like you're good to go.

The A1000 is pretty loud but i don't mind it. I'll look into the 6 micron filter. The filter elements are SS. Later I plan to turn this chassis into a Texas mile car with a 20b turbo. This motor will go into a touring car with a small gtx30r for more street activity.

Make an assessment...
iTrader: (3)
Just curious...Are you running off the stock relays still, to tell your pump to switch between high speed and low speed? If so, did you do the fuel pump relay/rewire? Back in 2010 I was on the dyno and would plateau at 300whp every single pull, and my system was built to the hilt too. I even had the Kenne Bell BAP, so I cranked that up, along with turning up the FPR and also dumping fuel in on the map, all with no change. Once I did the rewire, I was able to get above 300whp. Just a thought. I would imagine since your system is a pretty insane setup already that you don't use stock wiring, but it sounds a lot like my issues back then.
