Akina's build

[halfspec]

I am monitoring with a infrared temp gun and a temp gauge with sensor in the return line after the cooler, before the tank. I can watch the temp rise and the voltage control for the pump increase once it hits about 110-115 on the gauge, boiling point
Good eye on the return line. Ran into this before getting to drive it long enough to heat the fuel. That was a issue but i move the return line to the other end of the tank, basically extended the return line so its a good distance from the sock. What actually made me notice the problem was the pump speed changing erraticly due to the regulator trying to keep pressure inline with the airation the pump was picking up. Very sensitive speed control.

Good man! That airation in the fuel will also lead to a noisier pump via cavitation if you didn't already know. It's a nightmare if you don't know what's going on. Glad you got that part sorted though 

I think your method for measuring your fuel heat is sound. I now see that you're saying the temperature of your whole tank of gas is rising which definitely is concerning. Its been a long time since I've browsed your entire thread so the next couple of questions are lazy.  Do you have any lines that are close to your exhaust / headers? Did you use any heat sleeving for areas that are? Have you coated the tank in anything that's potentially insulating? Using any in-tank foam?

I was eying their 510 series as well. I was going to do custom valved Bilsteins but it seems like it will be a lot of time and testing to get things where I want them... and it will end up costing more. Were you able to get a caster and camber plate up front or is it camber only?

Once I figure out my spring rates with my current BC coilovers (which are not horrible), I will be ready to move forward.

I got the camber plates but the cast/cam plates are not available yet for the FC.
I debated on a lot of different packages before going with these. Affordability wise there on the high side of my budget but bang for the buck there as close as your gonna get to a fully built, custom, one off suspension.

Thanks and yeah the complete system is heating up. With the temp gun the fuel tank reads 115*, when the lines and gauge read 137*.  The tank is insulated with that black material that mazda coats them with from the factory. I do have fuel media in the tank, not foam though.
My exhaust system is DEI lava wrapped except the headers/mufflers and at the closest point to the headers it is insulated with DEI sleeving - fibermatt with reflective material.

Well after thoroughly testing everything I can, I have decided the fuel pump/system is just flowing/returning fuel so fast and its picking up heat from the rails/engine bay and there's not much I can do other than change pumps or change fuels. So onto E it is.
I have been going back and forth between the fic 2000's and the bosch 127's. The fic2000's scare me due to what type of injector they are and the issues they have considering this car doesnt get driven every day and sits pretty much all week. The 127's limit me to what kind of power I can make but is a true gas injector and would be better in my scenario I think.   Thoughts?

[Jordan Innovations]

ID2000's or similar for sure.  Won't have problems with Ethanol driving once a week, more like if you left it all summer or for a year.  You'll run out of 1300cc injector pretty quick.

[mefarri]

I know Magnafuel recommends using a fuel cooler on the return line for street cars.

[zbrown]

The 127s will get u to 1k who easy enough on E. Just depends on how much u want

I am still holding out for the new id1600

[AKINA FC]

Well I just had a nice conversation with Kyle at fuel injector connection and ordered the 127's, will have them tomorrow. Kyle told me he will let me know when the 160, 180 and 200 come out later this fall and will trade me/upgrade me to the bigger ones which is awesome. This is the third set I have got from them between me and my friends, good people to deal with so far.

I think your right Zach, I was reflecting back on our earlier conversation in this thread and these should keep me happy for a while or at least till the bigger ones come out.

I agree Jeff Ill max these out quick but I sometimes let this car sit for long periods with work, so I just dont feel its worth the chance. You seem to play with yours enough and its warm year round for you so I dont think you'll ever have a issue. One day Ill move out west haha

Yeah Matt I installed a 16 row, 8 AN Derale cooler with a 10" fan on it. Dropped temps by about 20* which makes it driveable when its cooler out but in 100* temps it cant keep up and looses pressure in about a hour or so depending on ambient temp. Having the hood off does help so a bunch - about 15*- so I am going to do something there as well, maybe a Ronin hood or designing some louvers, naca ducts. Dont know yet.

Using Lucas low impedance 120# units, we made 911 RWHP with ~20% injector left at 45 psi, on E85 on Nick's car.   I have ID1300s in mine and they should cover ~900+ RWHP on E85 by my math (58 psi).

Blake you running 58psi static?

The problem is boost - it's not the power so much as the pressure.  Unless you've got an insane fuel pump that'll do 4bar base + 2bar boost, you'll need the big injectors, since you'll be lowering pressure to keep pump flow up.

58 psi with 0 vacuum, then boost referenced.

Well things are finally starting to look good for a change. Switched to e85 and fuel temps dropped, consistent 118 under cruise and 121 for a high after a long pull. I can now grab the fuel rails and filter after a drive which is impressive to me. Engine temps appear to be lower as well. Neat stuff to say the least.
One last issue to resolve so far is the regulator appears to be overly sensitive and the pressure oscillates about 4 psi under any condition and will level out for a few seconds then oscillate again. Spoke with josh at fuelab again and he is doing some research on the regulator as they changed programming on the newer regulators for this same kind of issue. Hopefully that will be the fix as I went through the wiring thinking it might be some sort of feedback and could not find anything.
So far 14 psi at 5500 and it feels like a rocket! Should be about 16-17 psi at 6500-7k.

Congrats!

I also had troubling fuel pressure feedback issues, however mine was due to an on rail sensor. Got much better feedback at the FPR. Looks like you've got that covered.

Have you got your hood on yet? I only ask because I had problems with my FD's hood clearing a fuel filter that was mounted right over my vacuum booster exactly like you've got yours setup. Hopefully it won't be a problem with your setup.

[AKINA FC]

Yes hood is on and everything clears  The FD appears to have less clearance back at the fire wall than the FC.

On other news still awaiting information from Josh@fuelab.

That's my dude right there, definitely buying beers next time I see him.  I'm interested to see my fuel temps now, reading all this... the Infinity reads the FlexFuel sensor's frequency for ethanol content but I haven't seen a way to parse out the pulsewidth data (which is how it conveys fuel temp).

Josh has been real good to me so far. Spoke with him again this afternoon and found the regulator I have is one of the newer ones with the current programming. So I am going to do some more testing by bypassing the cooler to see if the added resistance in the system is causing minor fluctuations in the system that the regulator is trying to compensate for. If so Josh told me to ship the regulator and cooler, if i want, to him and they will reprogram the regulator for my system. He is also going to be racing his bike's here next weekend at heartland park so I will get to meet him as I will probably be picking up my regulator from him
I would love to see what kind of temp's you are running as I have nothing to compare it to as well. One thing I have wondered is how much the temperature varies with ethanol content, even though it doesnt really affect performance just more of curiosity sake.
