Supercharger or Turbo conversion for AWD tj magna

The biggest restriction in the fuel rail is the joiner between the two rails. I've pissed that off and run a braided hose between the two, plus the same size hose from the reg and return line. AFAIK you dont need to run dual feed rails in these cars, but it doesnt hurt.

*has one of these for sale if anyone is interested* Just a plug there...need to get rid of it.
but thats why I got one (albeit i do buy alot of random stuff).......was told that the kink in the fuel rail is just another slight restriction which doesnt need to be there.

if you check the 3sx website, they also have aluminimum fuel rail loops for sale too.

The fuel pressure problem is addressed by fitting a 7th injector into the intake manifold in a Sprintex system.

That in itself makes for an even amount of extra fuel to all cylinders since they all have the same length induction path.

However it is a form of throttle body injection which is notorious for bad fuel economy.

Not to mention the 7th injector being a lazy band aid fix to what is a problem that should only be fixed properly.

While yes, the 7th injector is a crude form of extra fuel injection, its hard to tune for uniform control too.

it also - would cause a DROP in fuel rail pressure when you think about it.
The 7th injector in the sprintex setup - is a big one..... when it opens... a fair bit of fuel goes in (trust me I know - was driving the car around with it pretty much firing all the time....)
When the injector is open - the fuel in the rail is being let out... which would lower rail pressure for a moment or so until the fuel pump has pumped more up again.

Thats how i see it in my mind - instead of 6 controlled leaks - you get 7 (altho.. the extra is a hard to control leak!)

To contridict the bad ecomony idea:
while yes - if your running an EA Falcon with centrepoint injection - thats bad for economy. However the Sprintex system, only adds fuel when its needed through the 7th - its not ment to fire ALL the time!
If you drive it like a hoon on full / big boost all the time.. then yeah.. the 7th will fire away happily.

sorry, but they don't have the same length induction path. the blower outlet is as far to the drivers side as it can get, which means the cylinders on the passenger side are quite a bit further away from the outlet than the drivers side ones.

that's why there's an upright in the plenum to evenly distribute the pressure. I'm sure it helps, but I'm also sure it doesn't fully compensate for the difference in distance.
