Found some old threads on here about low boost turbo on the cheap.
In them, they recommend a rising rate fuel pressure regulator if megasquirt isnt an option.
I have a 2000 1.8 car and a vortech supercharger. Im thinking that if i place the maf on the intake side of the supercharger and a boost reference regulator or fmu, i should be fine at a 6psi Street car. What says the hive? It could possibly be a challenge car....
I have a 5th injector setup for that car that is PNP. Pulls power from the fan setup and has a vacuum reference to determine flow.
PM me if interested
OLD threads. FPRs are the quick, dirty and risky way to do it. The biggest failure is forgetting to upgrade the fuel pump, so it gradually fails and your car gets leaner and leaner...
An electronic doodad like the Voodoo Box is a much better choice. Your power limit will be the ability of the stock injectors to deliver fuel. It'll also work with the stock ECU to prevent a lean tip-in condition.
voodoo box is like $400. microsquirt is $300. either one is a much better low buck option.
A rising rate FPR would be quite difficult to fit to an NB anyway, because of the non-return fuel system on that car.
I totally forgot about the voodoo box. That and a wide band sound like a much easier way than MS to control my idiot Frankenstein build.
But if it's limits are the stock injectors, would it be a good idea to run a boost controller as well, or am I over thinking again and this acts as a boost and fuel controller.
I left that last part in for myself, decided to read installation instructions before asking dumb questions. It sounds like I'll need a wideband, 94-97 injectors, and someone with good hearing to catch knock, yay something is simple for a change.
Sorry for the thread jack duster, but my turbo came in today and this thread was just too relevant to my interests to let it go.
Duster's asking about a centrifugal SC, so no boost control.
RevRico asks about boost controller, so that's a turbo question. You will have SOMETHING to control boost, even if it's just a wastegate. You will adjust that something so that you don't make more boost than the stock injectors can support.
In reply to RevRico:
Your thread is the inspiration for this one.
So its cool.
Everyone else smarter than me: thanks. No way I can pull this, and the other work the car needs, off for challenge budget. So i apologize for wasting time and bandwidth.
You can sort of do boost control with a centrifugal supercharger. They generally will have a LARGE bypass/blowoff valve for part throttle operation. You can use a 2-way solenoid to gate in vacuum from a canister to dump all boost in an emergency (low fuel pressure switch?) or you can run a second one that is controlled by pressure instead of vacuum, to limit boost.
Yes, but that's a bit of an unusual setup. I've always thought it a bit odd myself.

True story: I installed a Procharger on an LQ9 that already had a healthy cam in it. It sounded exactly like the start on this video.
Same for the "first start" when we took a customer's already-Procharged LT1 Camaro and added a 3.75" crank and some better heads and a cam whose specs I have long forgotten but were definitely in the popcorn popper range. The car detonated the 4L60 on the second dyno pull
