High horsepower fuel setup help!
Hey I dyno'd/tuned my car this past saturday. Everything went well
The new motor sounded very strong and the new setup is Kick ***
http://youtube.com/watch?v=nyA1Lp77Qgo
However I was not able to push the boost like I had planned due to fuel pressure
dropping at around 26PSI (Boost)
I have a walbro 255L HP pump feeding a inline surge tank with a -12AN outlet
screwed into a Aeromotive 100 Micron -12AN Pro Filter then into a Aeromotive Eliminator -10AN line from there up to the firewall then reduced to -8AN to the rails
-6AN return back into the surge tank, the overflow goes back into the fuel tank..
I still like to run the car on the street so I don't want a weldon
or another aeromotive pump (pump runs fine till I'm stuck at a light)
My question is would 2 Bosch 044's support 650rwhp on a rotary application?
which would require 70+PSI of steady fuel pressure no drop..................
If not I could just say F'it and use 3 044' externals off a surge tank
y'd into a -12AN line then y'd -8AN into the primary and secondary rails tied together at the regulator.....................
I just want make sure I have no more fuel issues next time I tune

well lol I didn't record the highest boost pull
thats pretty close for that lower boost pull on the vid
started off at 15PSI wastegate spring pressure to 26PSI on the Boost controller
1st pull right off the bat @15PSI was 429rwhp in the upper 10 AFR's
Gaby had to dump fuel to try to smooth out the curves on the screen cause of the weak fuel pump
Next time around with a better fuel system we'll be able to lean out the AFR's with out pressure drop
No secret My Goal is 650rwhp..... I don't need 700-800 rwhp to run 9's
Theres a saying Big Turbos require Big Boost Next time It'll be big boost

I did have 2 walbro intank but I don't trust them at high pressure ratios
I'm thinking of how to design a 3 pump system (actually 4 pumps with 1 swirl pot feed pump) since I do got a extra walbro pump I could stick in the tank again
1WLB+2 044 externals
This for future growth potential in case I decide to step up even further and run 6 injectors and beyond 3Bar aka E85

C16
Final numbers where in the mid 500's (I might attend a local dyno war so actual numbers shhhhhh
will go again for 32-35 PSI in mid to lower 11 AFR's and Q16 fuel instead of C16
Bullseye Turbo was really picking up steam as we got closer to mid 20's
and I'm sure would screem! in the 30's where it really like to make big power

yea but I would have to get a fuel pump controller
must cars I've seen with weldons and the like are trailered street cars, cause the
small print on those pumps read "Limited street duty" I actually do drive my car around for quite a distance in and out of traffic
We'll see what I decide on. I'm parking my car for a bit

Well when it comes to Aeromotive what do you consider a reliable product
5% failure rate
10?
15?
20?
50?%
seems to me its about 30+ failure rate on there red pumps
In any other company this is unacceptable quality

nope 70% have there pumps last a few years with a pump voltage controller
or in most cases very little street duty...
30% failure rate is unacceptable
do a search on many many diffrent car forums over half the responders have bad things to say about Aeromotive Red pumps

Oh, I know this. I've known this for years, ever since I put one on my FD back in 2000. I heard alot of bad things from the ford guys but also heard alot of good things. It's a toss up. If mine failed me, I would switch to a Weldon.
