Fuel Pressure Power Boost Valves...You Vote!

[EJ Doc]

Out of intrest i would like to know how many of you think these valves are good and how many of think these arent worht touching.

I have heard some bad things from some of you guys but i have sold them for a long time and used them alot on our applications, and they have never once given us any problems when set up currectly.

Just intresting to see your view guys

Cheers for now,

name and shame in the rules of posting buddy.....
but as they are a generic idea, i personally think you'd be better hooking up your aircon into your inlet

Are these the jobbies that introduce an unmetered airflow into your intake system?

The raise the pressure of the fuel line. I had a HKS one on the MR2 and it drove very well. It was £30 direct from Japan. I wouldn't bother spending £80-120 on one over here though when you can buy an uprated fuel pump for a similar amount.

ah so you are awake

Aaah, so they are basically a different spec fuel pressure regulator then, or are they fitted in addition to the standard regulator?

Regarding the info on these fuel pressure regulators this is what the Glencoe book says:
"They are an designed for use on electric fuel injection engines with a special fuel enricjment facility for acceleration, commonly known as a'rising fuel rate. the enrichment is 1.7:1
Benefits are:
Suitable for standard and tuned vehicles
Quicker throttle response
Faster acceleration
Throttle hesitation(inmost cases eliminated)
Formal idle (with adjustment) retained.
Normal economy on light throttle"

They let you run the engine richer under power, without the cost and hassle of remapping. Sometimes running richer is a good thing, sometimes it isn't. If your engine has been modified significantly then you would almost certainly be better off getting it mapped properly rather than just richen it up a bit. And if it hasn't been modified, why would you want to run it richer than standard?

An indirect advantage is that it extends the range of the injectors without compromising the fine control at idle, but that doesn't seem like a big deal. There is a well known brand commonly fitted to TVRs in the UK which has a reputation for 'going soft' and losing pressure over time. I'd suggest that the slightest lack of consistency/reliability in maintaining fuel pressure is more important than all the other considerations.

well you know I think they are pants, as do those in the "know " in the Supra world. As far as adjustable Fuel Pressure Regulators go there are far better for not much more money. I am sure they have there place though.

I had one on my supercharged Corolla for all of 2 days. The stock regulator kept the pressure at 42psi at idle not matter what. The FSE would range anything between 39psi and 45psi at idle - no good to man nor beast. The stock one has been back on ever since.
