MG TD TF 1500 - Marshall blower on ebay

Marshall-Nordec supercharger on ebay at the moment.

Just a heads up.
JIM NORTHRUP SR

Sold for, would you believe- $5,500 + shipping!?!

Anyone here the proud owner?

Not me. I haven't got rocks in my head!

I had a couple of bids at about $2500 but it got far to rich for me especially since you can buy a new kit from Moss for $4500. By the way I thought these kits were around $3000 when first introduced a year ago.

Let's all just sit back and see if someone in the next month or so posts a question on "issues installing a Marshall Nordec blower".

Ray Coyte

Why is it the Moss blower isn't available for a TF? PJ

On the Marshall blower, I wonder if the seller gave the buyer a kiss to close the deal?
Paul Jennings

anyone know the auction number?
Rod Brayshaw

"Why is it the Moss blower isn't available for a TF? PJ"

Because it won't fit into the engine bay without modifications.

I would rather go for a blower from MGT repair. Fits my TF.

Some people say that a supercharger should not be higly polished externally as that will impede heat dissipation. Theoretically that is obviously correct, but will a supercharger get that hot, while chewing high volumes of fresh air?

It will still require some small modifications to fit in a TF.


Yes it will generate considerable heat compressing all that air.

MG LaVerne

Roots type superchargers will really only generate heat under boost, they're sort of internally air cooled under manifold vacuum, refrigerated actually! They're also low boost, as opposed to really high output turbos. We might see steady 4psi boost running down the highway at 80mph.

The temperature difference between the "as cast" housings and "polished" surfaces would be immeasurable, in my opinion, no more so than an argument that polished surfaces would be microscopically thinner and so run cooler.

A more serious concern for heat, to me, is the proximity of the blower to the exhaust manifold (crossflow heads wouldn't have this problem). As hot as the footwell gets in the summer, the blower must be getting awfully preheated! I started making a stainless heat shield but never finished it. I did cover all the exhaust pipes, from the manifold out past the back bumper with flexible stainless tubing to knock the convection down, but not by much! I do want to start inserting thermocouples in the engine compartment to expore the heat issues. Have stuck one in the O2 ensor bung to measure exhaust temps. You guys driving around without the bonnet louvered sides know what you're doing!

The real heat issue arises from the higher temp air instantly shoved down the manifold. Without intercoolers, that hot air (along with increased pressure) can invite pinging. Gotta keep the timing a bit more retarded than normally aspirated carb only engines. Fortunately, our old, lower compression engines are perfectly designed to accept superchargers with todays gasoline. We run regular, and haven't experienced any "audible" detonation. Installed a "knocklite" for warning, but it never blinks. One of these days, "when I have spare time," I'd like to hook up laptop oscilloscope and actually watch the signal from the knock sensor.

LaVerne,

Can you fit an air cleaner in there or do you just count on clean mountain air?

LaVerne;
what kind of modifiations are needed with an MGTrepair supercharger in a TF? I may be ripe for one...

regards,

Jan
JE Kristoffersen

I use a K & N filter. I've got an MGB filter base plate inside of itto reduce the turbulance flow.

As you can see Jan, the starter switch had to be moved. I put the bracket on the inside of the bulkhead.



MG LaVerne

Remove the front latch assembly but put the button back on. Bonnet will stay closed just fine without it.

MG LaVerne

Here is the part you may not like. I had to cut the forward brace from the bonnet because it rested on top of the pulley.

MG LaVerne

Just removing the catch wasn't enough.

MG LaVerne

Little paint band all is well.

MG LaVerne

The fender cross brace goes away as well, which after 20000 miles I can confidently say it isn't needed. In fact unless I owned a 100 point car I wouldn't put it back in there. It's a major pain in the ass to work around.

MG LaVerne

Might be some other modifications I'm not aware of as the super charger design has changed since I've done mine.

Maybe Tom has sold one of the newer units to a TF owner and they could shed some light on it.

By the Jan, the last picture is what you will be looking at if you ever have to do any work ...like changing an exhaust gasket, head gasket..etc. You can't do any of those things without removing all the sheet metal on a TF.
MG LaVerne

LaVerne,

The main change that I'm aware of is the front mount. The snout of the supercharger is now turned down and the mount is made to fit over it so the front support is now infinitely adjustable as to where you bolt it to the front engine mount.

LaVerne, I just noticed the name change.. Love that >>>>
Tom Maine

I tried to put my name in there Tom but I had an old account that got hacked and it wouldn't accept it so I went with the MG. It still won't take a picture to go with the Name??? My initials (LED) confused a few as to what my name was. So I hope this is better.
MG LaVerne

For anyone that wants to join the supercharged club, contact Moss or Tom Lange for a lot less money:
http://www.mossmotors.com/Shop/ViewProducts.aspx?PlateIndexID=112337
http://mgtrepair.net/Supercharger.html

They both use the Eaton blower. I'm prejudiced to Tom's package, but it is sort of like choosing which of my wife's breast I prefer, the left or the right one!

You don't buy a supercharger, it is an investment that keeps growing as time goes on! The Marshall kits started out as just a couple hundred bucks!

{picture: our Marshall during '50 TD overhaul. How sweet it is!}

JRN JIM

My Marshall on my MKII, works just fine.

Marvin Stuart

LaVerne,

Could you please post a Photo of the relocated starter switch when you have the time ? Thank you!

JE Kristoffersen

I still have not got rid of the supercharge bug but right now I cant afford one. My engine was built for a supercharge, custom Venolia pistons thicker heads, Crower custom rods, New crank etc. My next investment is going to be Lens roller cam.
Tom Maine

Here is a picture of the bracket Jan. Moved to the inside of the cockpit. The switch is still on the engine side, but is flat against the bulk head as shown in the next picture. The is no room for a filter otherwise.

MG LaVerne

Not a great picture but I think you get the idea.

MG LaVerne

My supercharger came from Tom's supplier before Tom took over distribution. My TF was a "test mule" for TF fitment. Originaly it had a very nice cast piece between the blower and the carb, but it was impossible to fit it on the TF. So we had to use the flat plate adapter shown in the first picture.

MG LaVerne

Interesting to appraise the value of a Marshall blower, in pieces, by the bidders:
5 bid over 2 grand;
3 bids over $2,500;
2nd place bidder went $5500;
winning bidder??? priceless!

A clean running Marshall-Nordec, like Marvin's, to me, looks like a million dollars!

Max,
To get back to your question, I believe the new Moss package has always been well over $4000. Currently it is $4595, with no discounts applicable. I seem to recall paying about $2650 for our Magnacharger from Moss, back about a dozen or more years ago.

I often think about those blowers mounted in front of the engine, driven by a shaft straight off the crank. The long intake runners served as crude intercoolers!

JRN JIM

Thank you for the pictures! It seems like fitting a supercharger to my TF is more of a winter job than a weekend job. And for peace of mind the engine should probably be opened up and inspected . Although my XPEG seems to be in good condition I do not know what the PO did inside it. Magnafluxing rods and crankshaft would have been nice.
But then - if it ain't broken don't fix it?

Regards
Jan

JRN, here is a photo of a Toyota S/C14 supercharger I made up for my TC. I am thinking of adapting it for my TF.

As we seem to have moved away from the Ebay blower, anybody have any comments to make about the supercharger designed & built by Terry Peddicord from Mirage Garages? Pic attached. I understand it fits TC's & TD's with minimal & easily reversable modification. And a lot cheaper than the Ebay job! I believe he used to be associated with Moss.

The "Mirages Garage" blower is the unit I offer - Terry Peddicord, who designed and engineered the T-series system, sells to Europe and Down Under, I sell to the US. Please see my listing at

mgtrepair.net

It is a tried-and-true kit, with dozens sold successfully world-wide - I am putting two kits together right now for customers! Installation takes about two full days, with TFs taking just a bit longer, due to the access difficulties. We have not found that this generation of kits requires ANY TF cutting, just removal of one bonnet latch and some relocation of pieces under the bonnet.

Read this article for one owner's installation experience (he chose to have a mechanic do the work): http://ttypes.org/ttt2 in issue 7, pages 13-16.

My price in the US is $4295 - unchanged for the past few years - and includes the following: new Eaton supercharger, intake manifold, all necessary hardware (ARP quality) and linkage, belt, idler pulley arm, completely re-manufactured 1.5" carb from Joe Curto (ready to install, with overflow pipe), and complete instructions. Lead time is somewhere between 4-6 weeks, and we have had no problems with the unit.

For clarity's sake I will also start a new thread with this message, since it seems to have gotten somewhat far afield.

I'm happy to answer any questions, and know that some purchasers may want to recount their experiences.
