Hudson Turbocharger

[Deleted User]

Rudy Bennett (Super651) sent me an eye opening e-mail that contained pictures of his setup. Hot off the press Hudson performance engineering from the man who brought you the Triple-H and other pieces that has won my admiration and respect in the "Hudson go-fast" world.



Quoted from the e-mail:



The turbo is a T0-3 Garrett from a Buick ( carb suck through ) along with a 2-barrel manifold.

The intake is from a 49 262 and is Aluminum with a stock ex-manifold.

We had to build all piping from ex-to the turbo along with the Black elbow that goes between the compressor and the Carb box.

This complete set-up can be unbolted and installed on any Step-down ,just connect the oil supply to the main oil supply under the manifold and install the carb linkage to the Hudson bel-crank and a fuel line and is Go set-up

We are using a 500 Holly 2-barrel carb and with about 6 lbs of Boost it will start to PING. ( we will add water injection and a MSD Boost control this week to eliminate that)

This 46 has a 2.73 Roadrunner diff.(no overdrive) and you need to slip the clutch a little to get it moving but the, when the Boost starts to come in it will pull like a 308 +

and has very little Turbo lag.

( i ran a 308 jet drag car in the 1970s but could not keep head gaskets on or Flywheel bolts tight,thats another story)

After all the bugs are worked out it will be installed on my Newly Rebuilt 308 with 200-R-4 Trans.

Hope this will be of help to tho es that are wondering how a Hudson would run.

No hot cam,porting or bigger valves is needed when set-up properly.

Hudsonly to All. Rudy and Rick B.

AWESOME!!!!!!!!!!!!!!!!!!! What is not to love here????

I tell you what...I'm a hands on guy...like to get my mitts into every part of the build...and it's not that I don't think I could do something like this fine example - I just don't know the internal mechanicals of a Hudson engine to know what I'd have to do to keep one running with this kind of additional HP!

Hat's off to some really nice looking work and I bet it sounds pretty cool to boot!

Hi Mark This looks close to the same as i have except I have 4 Barrel carb

I would sure like to see that setup.



Got pictures? We'll get them up here for you somehow, if you can't get them posted yourself.

I just found this link on another forum...goes along with this thread very nicely I think...anyone see parts that they could put on a Hudson?

Rudy,

are you doing anything to boost reference the power valve in the Holley 2bbl carburetor?

If not this may be the reason for the pinging under boost as the power valve would see a high vacuum condition in a draw thru turbo arangement. If its vacuum sorce is not attached after the turbocharger then this high vacuum condition will be present when ever the turbo is producing boost.

As you know this will not allow the power valve to open and richen the mixture so you may be extremly lean at any boost level. I had the same problem on my old Corvair Spyder turbo set up when I added a 4bbl holley & adaptor.

Most of the time a passage would be drilled into the metering block, an extra vacuum nipple would be added that intersects the power valve passage and the orginal power valve passage in the main body would be plugged. A simple vacuum line connected to the orginal carburetor mounting flange on the intake would supply vacuum while not under boost and then blow open the power valve when under boost.

I got to admit this is one sweet looking setup! You got to tell us how it performs after you get everything tuned in.

thanks,

Hi again Mark

I'l see what I can do about some pictures of what I have.

Awsome pictures duncan

Hi Mark The adapter that you used ( alluminum) exatly what I was going to

use .Adapt the turbo to Hudson single 2 barrel intake. How would it work

if a person adapted it too twinH intake. I never dreamed of having

my name and being answered on this page duncan

super651

Thanks to ALL,and to PACERACER for the info on the Power-Valve we will check that before we add the Water-Inj.

When the eng.is cool and running with 3-4 degree adv.it will pull STRONG with 6-7 psi Boost and no Death-Rattle

This is a very worn 262 with loose valve guides but you would never know that when the Boost comes in,it just keeps PULLING and have to get out of it.

This is a test for better things to come,like a 308 with all New Parts.

Other than Blown Head Gaskets at times the other WORRY is the CON-RODS. They are weak just below the pin bore and I will now try to find a good Co. that can BOX in the sides.

Thanks to all as there is no turning back now.

Will let youall know more next weekend on the Carb-Power-Valve Mods.

Hudsonly Rudy.

duncan, the turbo setup is not mine - it is the work of Rudy Bennet aka super651.



Any technical questions regarding the setup need to be directed to him.



And welcome to the board, lots of Hudson speed fanatics lurking here.

Hi Rudy I replyed to your messages thinking that Mike was doing the

turbo build for the Hudson. I have the same looking setup for adapting

the turbo to the Hudson single 2 barrel manifold except I have a 4 barrel

carb. How would it work to adapt the turbo to the Hudson twin H intake.

I have pictures of the turbo and 4 barrel carb and a few pictures of my 54 Hornet Hollywood in final primer ready for scuffing and sealing then paint

I don't know how to send the pictures duncan

Twin-H...Twin-Turbo Hudson?

super651

Duncan,Go for it. When you use a SUCK-THROUGH Style Turbo it dont care what you use. You could put TWIN Pipes from the Turbo down to the Twin Manifold. ( may try that on my 51 Super-6 later)

We should have the test info on the 46-Turbo,later

It is still Hoooolding Togather ????

Thanks to all Rudy

( the turbo is soooo Far from the intake valves and the Commpressor Wheel does such a good job of mixing the fuel and air that the engine runs smoothly and more Power even with No-Boost,+ instant starts,Hot-Cold eng )

Posted the following for Randy and Rick.... check out the pictures too



This is the test on Casper as i reported to lots of you by Phone and P.M.

1946 Super-6-4 Door X-SHINE-RUNNERS-CAR ?? 1951 Highly Worn 262 eng. with cast iron 232 cyl head.

Turbo is by Garrett -T03 as was used on a 78-82 Buick Regal Carburated type.with a holley 2-barrel 500cfm carb. Std fuel pump.

Start-ability--Cold,needs one pump on the accelerator and starts instantly at 29 degree amb.temp. The short pipe from the carb adapter gets ICE-cold until the heat from the radiator fan becomes warm. ( a little hard to warm up)

Eng hot --if a piston brakes over-center its instant fire-up and no flat spots ( due to the carb being so far from the intake valves and the Commpressor wheel mixing the Air-Fuel it burns clean)

Ignition -- is a MSD-Blaster coil running std points through a MSD-Boost Timing-Master #5462 ( same fire-power as a HEI,points act as a switch only) at 4-5 lbs of boost retard is 12 from the setting.

Road-Test, Amb.temp is 80 degree. Eng. temp is 190 ( had to lower the boost from 7 to 4-5 psi so as not to Blow her up ) At around 95 mph and with 3 lbs of boost the carb was not wide-open I turned Chicken and backed off ( the chase car had a Calibrated Speedo) and he was not the LAW.

Hill climbing from 3,800 ft to5,000 ft wehad to use second speed and MPH was 45.

With the Turbo we pulled it in third gear at 60-65 mph and boost at 3-4 lbs. ( carb not wide open) with No Death-Rattle.

Ex-pipe is 2 and 1/2/ Id from the turbo. to the back bumper and is Not Loud at all,as the Turbine Wheel Diffuses the sound as it scavenges the ex-system.

The only thing that we did not do but,should have,was to wrap the complete ex-manifold as we did the turbo pipe so as to keep the intake manifold a little cooler.

( it will be done later)

SO--- it was well worth it as we were shifting gears to much and now we just ease the pedal down ,watch the boost go from a vacum to a Pressure and Feel the power in the seat as well as the pocket-book.

We will get some fuel mileage testing in a week or so. ( if I can keep my foot out of it)

Again,this is a well worn 262 with a STD-trans. and a Mopar 2.73 rear ratio.

Hudsonly to all Rudy and Rick

Bring it to Muncie Rudy. Will run you if you give me a four car lead. Looks great from the pictures.

That sounds like a Hudson only episode of "PINKS"!

super651

Good try Randy but, Iwill be on your pit Crew.

I found out last night that the clutch is the WEAK-LINK after a few runs you have to get off the ( foot-feed) as we used to call it .when you make a shift from 1-2-3 because if you are in the Boost Range the Clutch Slips.

To many hard miles and i guess thats next.

( I know that it was NOT the rear wheels slipping,not with a 2.73 ratio )

So I will Chicken-out-again. Thanks for the try. Rudy

Rudy--How about if I send ytou stiff springs for your pressure plate? That should hold that cork in place.



Randy

super651

Please do. as we will have to get in there in the next few days

Thanks so much. Pal Rudy

Rudy,



I was wondering what timing points you have your MSD controller set at per psi of boost? A timing curve compared to vacuum/boost @ whatever rpm would be terribly important information.



Whatever you've discovered with your turbo outfit would be a huge help in setting up any other forced induction outfit. I haven't installed the McCulloch yet, but this very topic is weighing heavy on my mind before getting neck deep in the situation.



Mark

Mark, I will find out tomorrow and let you know.

Thanks Rudy.
