Webber Alpha FPR

[AM400]

Anyone running one of these on their Wedge?

I want to ditch the FSE rising rate regulator and was looking at the adjustable Webber. Might even go for the fixed pressure version 3 bar.

Yes it's what Mark Adams suggested - adjustable with a temp gauge is the way to go

[AM400]

Have you been running with one for a while? I don't suppose you have a picture of it in situ? Looks like I can probably fit it where the original was if I make a bracket up. Think I will be getting one of these over the weekend, thanks.

Since a rolling road run was aborted due to being dangerously lean - discovering a std Land Rover FPR was fitted (32psi!!)

Will take some pics over the weekend

You may also wish to consider this one from Jenvey:

I made (well hacked) the munting bracket from sheet ali

[Number 7]

Ran one on mine for years (originally fitted by a TVR dealer when they stuck in a bigger engine)at around 42 psi IIRC. Gave it away to a PH'er some time ago when I fitted bigger injectors and a hot-wire fuel rail, as it would not have been straightforward to install the Webber.

[Transmitter Man]

Excuse me if this is a dumb question but with the Hotwire do you then not need a pressure regulator?

If not, why not?

Yes you do.

The rolling road people got me a FSE 'boost valve' adjustable regulator for my hotwire 400SE. Part number VK-384-18-H, so the fuelling could be got spot on.

Yes, you do, but the hot wire rail is made to accomodate the standard fixed FPR directly, not on a hose, so fabricating a bespoke connection would have taken time, and the car was in for a mapping session.

[Transmitter Man]

...and from what I've been told the ideal regulator on anything but a flapper is a 3 bar fixed rate.

Agreed?

I can't say I've heard that it's ideal, although I guess once you start playing with fuel pressures, you should really look at the fuel map itself,which doesn't seem to be that easy with Lucas systems. I have heard of people slightly crushing the fixed FPR's to increase pressure though.

Thanks Cuneus, I have ordered one today.

Andy,

Are you getting the Jenvey 3 Bar?

Why not get the matching bracket for a Few Dollars More and make less of a pigs eye of the job

The Jenvey one is actually the Weber Alpha regulator. I am going for the adjustable one and don't worry about the bracket I have some stainless flat bar somewhere and I am a dab hand at polishing now!

I have concluded that I hate rising rate regulators, as they are just a band-aid to a properly mapped engine - which means fitting an aftermarket system, which will also control your spark advance too - which all improves the engine a fair bit too.

I think I'm going to invest in a Megasquirt and be done with all this pratting about.

You not going to go Emerald, That's what a lot of the Rv8 TVR guys use.

Yeah, I agree about the rising rate regulators hence my changing it. If I had the choice and the money I would go to carbs. Nothing like the intake roar from 4 downdraughts!
