FSE Power Boost Valves! Absolute pile of shite!

If you have a BPU set-up and use an FSE power boost valve (fuel regulator) installed on your car, I would seriously recommend that you ask yourself what you are trying to achieve, and justify why you need it in the first place.

My VVTi Supra is currently on the market (now provisionally sold), It was viewed by a potential purchaser over the bank holiday weekend! couldn't fault the car until he followed me while I was driving and noticed a puff of black smoke when I was booting it and shifting gears, it was something I've not noticed before, it was obviously running rich, perhaps too rich.

The car was at phoenix today for a service, spark plugs were changed, and the fuelling was looked at, along with a leak down test to ensure everything was ok internally! I couldn't be bothered checking out the FSE regulator and opted to re install the original stock fuel regulator, and WOW! what a difference! Its so much more responsive, my car is now running better than it has ever been! I am absolutely amazed at the difference! It also feels more torquier at lower revs which was something I wasn't expecting, maybe with the car being a VVTi as something to do with it? The leak down test found nothing wrong with the cylinders, and the air to fuel ratio was checked out by Terry, and its now spot on!

If you've got this fuel regulator installed on your supra, I would seriously recommend that you BIN IT, whoever sold you the FSE, hang em buy the fucking balls!!

Goes to Terry Saunders and Mark from Phoenix who helped me out today

That's generally what I've heard too.

Perhaps if you're running twin uprated fuel pumps to a massive fuel rail on a single turbo conversion you will want to properly regulate the fuel pressure. But a decent one. I run a Malpassi on the kit to prevent the carbs flooding.

they are shit? Really? Next you'll be saying the piss fuel all over the engine bay at random intervals And they are some ghastly crutch for an inadequate fuel system. And so forth.

Perhaps it was never setup properly in the first place.

Lets be honest, theres only so much set up you can do, They are not 1:1 like the stocker or many other aftermarket FPR...Opps i broke a drumstick

There rising rate, and designed to give extra fuel on acceleration, probably more use on an N/A engine, but i think its down to the ECU as the Supra does seem to go very rich on acceleration, i used one on my S14 to good effect.

I know they are shit, I was in a confrontational mood.

Glad you got it sorted James.

Poor bloke. He comes on here trying to ward off everyone doing his good member bit and not to listen the marketing hype that surrounds these gizmos (which he or the previous owner was understandably sucked into) all you do is try to make him feel stupid and take the piss.

The potential power has truely been unleashed! Took it out for a spin earlier and Would love to see how this car performs on the rolling road in Surrey!

Ian C has been saying they are a worthless pile of mangled junk for years! I have just confirmed this, but with less techincal mumbo jumbo

I am the first owner who was sucked into buying this FSE from certain members on this board 3 years ago, when they were raving about how damn good they were!

I'd like to refer the honourable gentleman to this thread:-

I atill have 2 Toyota Team Europe, Bosch Motorsport quality fuel pressure regs for sale, you get what you pay for in FPR's .... http://chriswilson.tv/regulator/regulator.jpg

Agreed the FSE's aren't particularly any good, however the question is why did you have one in the first place? Surely increasing the fuel pressure on a car that doesnt NEED the pressure increased is only going to put you backwards anyway? (ie ANY increase in fuel pressure would have been pointless FSE or some other manufacturer) Or am I missing something?

Or am I missing something?

The idea is it maintains a steady flow of fuel at a set pressure which is right for the tuned state of the engine and eliminate possible pulsing from the fuel pumps. Not really to increase pressure, as Ian put it "some ghastly crutch for an inadequate fuel system".
