turbo regulators

[70 grabber]

I cannot seem to find anywhere a fuel regulator thats turbo referenced without it being made "only" for efi systems.I am trying to find one thats adjustable from close to 8-30psi thats boost referenced and has a fuel return. Looking to find something thats reasonable in price.I know low price and quality dont mix.but under $100 if possible. can anyone please inform me of their set ups if there is other ways or just point me in the right direction.

Well, it is not in your price range but Aeromotive makes a regulator that most of us are using.

adjustable from 3 psi to 60.

yea they are nice but way more than I was hoping to spend on a regulator.Is there a such thing as a no name regulater thats still got some quality?or I should just watch e bay! thanks

You get what you pay for.

Watch Fleabay. Linc got that exact model really cheap because the seller had no idea.

Also, try to see it differently - the return style regulator is very useful with either turbo or non-turbo applications. It's simply an investment in controlling your motor more effectively.

Yes you do and that is why I generally use just a plain old pressed metal one from a jap car. I've used ones from the N/A engines many times and they seem to work perfectly well on boost applications.

As long as they have a return line and a easily accessible reference port.

And also are adjustable.

Nah, adjustable isn't normally required. On injector engines the duty cycle handles the metering and on carby engines the bowl pressure held at constant rise above manifold pressure is generally OK in my experience.

My experience has been different. If you are using a OEM style regulator it is most likely set at a different pressure than is ideal for whatever system you are using.

I bought my aeromotive regulator local for $91. shop around for a deal. BTW they do come with springs for EFI adn Carb apps. (was a big plus for me)

there is a mallory #4309 with a pressure guage and fittings has a return and is adjustable on craigs list for $75 is this a good choice?also if I am running 10 lbs boost and have a regulator set at 16 psi does my fuel pump also need to flow at 16psi?

The Mallory 4309 works great. It's what we currently use.
Set the fuel pressure at 5 to 6 psi at idle and it'll increase with boost.
We've had it up to 17lbs. of boost (22psi fuel pressure) without any problems. And we run E85! It's been on the car for about 5 yrs. now.

Yes the fuel pump MUST be able to pump enough fuel at 16psi (in your case) to handle the fuel demand. A normally aspirated carb style fuel pump will not pump at higher pressures. Their fuel flow will quickly drop off at pressure rises.
If you're running 10lbs. of boost I'd recommend an Inline EFI style pump and obviously run a return line from the regulator. Walbro, Paxton, Carter, and others all make an relatively inexpensive pump that'll work just fine.

Later,
Will

thanks for the info. 10's thats flying man!!Thats seriouse for a straight six to run that fast.Oh I have one more Question about the carb. if I get an autolite 350 cfm does that have that atomizing or whatever setup from factory or is that just from pony carbs? and also what needs to be done to that carb? does it already have solid floats?
