There is one in the for sale section
When and on what did they do this??? Industrial application??

Re: NOS turbo 440 manifold??? - 12/12/10 05:27 PM
i am guessing a late 70's motorhome.i remember seeing a cam for it in the PAW catalog in the 80's.i am useualy wrong tho. 
found some pics here.

RV's. they would work great on a something like I built. the trouble is getting them to fit a vehicle

I bet that heated the floors in the RV!
What type of Thermoquad was that?

Probably a standard T-quad. That RV setup is a draw-thru system, which typically does not require carb mods.
Air goes thru the carb into an adapterplate, thru the turbo compressor, and then back thru a separate chamber in the adapter plate and into the intake manifold.

Do you have to richen it up a bunch for the extra air?
How would a air/fuel mix work going into a intercooler?
Fuel fall out of suspension?

You set it up like a normal carb but need to enlarge the needle and seat to allow more fuel flow.
They're great for fuel suspension. Most of the fuel gets mixed into a really nice aerosol. The down side is that if there's a leak you've got a fuel/air bomb on your hands. It's not possible to intercool and will ice the carb in cold weather.

i dissagree on intercooling.it can be drawn thru an A/W like with the roots but would need fab work to mount it over the intercooler core.just saying.
ps:my brother made 300rwhp on a KZ1425cc MR turbo kit draw thru [correction[S&S flat slide 40mm.

Re: NOS turbo 440 manifold??? - 12/17/10 12:08 AM
I thought those were really terrible for fuel suspension because you need to drag the fuel all the way from the carb, to the turbo, then back to the intake manifold. That's a lot of area for the fuel to cool and fall out of suspension.

Draw cold air through an intercooler then compress it and heat it up again?
Yeah, that makes sense.

If you have an overly rich condition you can actually spin the fuel out of the mix in the compressor. Keep the tubing runs as short as possible and you'll be okay with the mix under boost.
At cruise you certainly can have the fuel falling out.

no SIR!the draw thru carb setup gets bolted on top of the A/W that is on top of the intake.

That would help but I feel sorry for anyone with a backfire. That IC would be a bomb!

Re: NOS turbo 440 manifold??? - 12/18/10 04:50 AM
NEVER done any tweaking on this set-up but I have heard some reports from guys who have had this combo in motorhomes......
GOT to run premium fuel ... and with the weak as-is 440 in a motorhome chassis .. you are always "in" the turbo boost.
It is not the type of combo I would want to have.

I wouldn't think 6 pak rods would be necessary. Some did get them.
Cast pistons in there? I would want to run water/meth injection.

The fuel/air mix inside the IC core would be the bomb. Ignite that mess and it's going to blow.

that is what thay make the burst plate for correct?dont think that i am being arguementive,i like finding ways to make things work.

The manifolds were add ons. They were sold through a place called turbo power until about the mid '80s.
As for intercooling a draw through system... The minimal positive theoretical effect won't come anywhere close to outweighing the negatives that come with it. Draw through systems suck(litterally) and adding an intercooler just makes it worse.

Re: NOS turbo 440 manifold??? - 12/19/10 01:22 AM
so even with the I/C on the pressure side you feel it is restrictive?gaining 1 hp per *F IAT drop what is the negative?

Re: NOS turbo 440 manifold??? - 12/19/10 06:09 AM
The carb will ice below 50 degrees F. In addition, fuel will fall out of suspension in the IC through lower velocity and condensing due to the temperature and pressure drop.

Beat me to it. Your intercooler will fill up with fuel as it cools, condenses and falls out of suspension. Really draw through carbs are not a good idea at all. You'd be a million times better off in just using a holley double pumper in a blow through application. Better driveability, performance, safer. Draw through is doable with port efi because the fuel is still injected at the head. Yet it's still not the most desirable because if a turbo pressure hose bursts you have no means of controlling engine speed.

i do see a lot of fuel loss on my A/W with the roots but the velocity has me puzzled as the I/C would be no different the a tunnel ram with a plenum.i am sure the velocity gets complecated on just where the fuel would fall from suspension.thanks for your input.

I have a old RV Turbo kit on the 440 in my '85 W-350 Crewcab. It does really well for it's age and puts out 7psi max boost, on a 10 to 1 440 that's plenty for me

A real 10:1?
How's the MPG's?

Re: NOS turbo 440 manifold??? - 02/12/11 04:44 AM
True 10:1, the engine is a '68 with zero deck uncut flat top forged pistons, ported #452 heads, other than the intake the rest is factory stock. Yes it is water/meth injected with injection being triggered by vacuum not boost.
Mileage is 10-13 unloaded, 5-8 when towing up to 10K.
Here's a pic of it.

same principle as the Martin/ Accel units
