I'm new to working with 5.0's .. So i'm learning as I go.. I made a post a couple weeks ago but am thinking of going a slightly different way with the build... so a few more questions...
The project car I bought has some issues that I'm trying to remedy
So heres what the car has done to it currently
19# injectors
Stock fuel pump
Forged bottom end
GT40 heads
Edelbrock performer intake
Edelbrock throttle body elbow
65mm throttle body (Not sure on the brand.. but its screwed up..)
Paxton Novi 2000 S/C
Paxton FMU with a 10:1 disk in it
BBK Shortys
Off-road X-pipe
Side dumped exhaust
When I bought the car, it wouldn't run worth a crap above 3500RPM.. In the process of fixing that issue, I've found some other issues with the car.
In order to have a good running car I'm thinkin about upgrading some parts
42# injectors
Walbro 255lph fuel pump
BBK 65mm Throttlebody
Abaco MAF (spending a little extra money here so I can reprogram it as if I change injectors at some point)
Out side of these parts I'm not sure which way to go..
Now for some questions..
#1 Should I replace the stock fuel rail? I've been told it'll support up to 500hp or so.. but I'm not sure exactly how much HP to expect from this setup.
#2 Should I ditch the Paxton FMU all together? Should I go with a boost referencing fuel pressure regulator? Paxton says to go with a 4:1 disc with 42# injectors .. Should I find a FPR that has the same rising rate? If I go with the FPR, do I ditch the stock FPR? .. Which leads back to the first question.. Will I need an aftermarket rail to use an after market FPR?
#3 Would it be benifical for me to goto some sort of a stand-alone system? Or should I do a piggy back system? What ever I decide to go with I want to keep the cost as low as possible of course... but would also like to for it to be as plug-n-play as possible and real-time programming is a must... (I dont wanna mess with pulling a chip to make any changes.)
the PMS system from Anderson Ford is supposed to be pretty good from what I've seen. I was also reccomended a system from AEM (though its like 2x as expensive as the PMS system..)
What ever I decide to go with for engine management, I'd like for it to be upgradeable to what ever i decide to throw in the car later on.. Possibly an LSx motor.. maybe a turbo charged SBF..
Should I use a system that uses a MAP sensor instead of a MAF? Which one would provide the best streetability..
Thanks for reading my long post
