Om606/605 supercharged.
I say go for it! (But I'm no expert)
You know what you'll get with a HX30 but I don't think anyone's run just a large supercharger.
With the correctly sized pulley and a big IC you could have a monster off the line. Your top end may suffer though.
The specs from your SC will give us more insight.
I, for one, am excited to hear more!
Well, I got given it. So specs are limited to say the least.
All I know as of now is it's off a military Detroit diesel v6.
The charger is fairly large around a third bigger than a eaton m112.
Was told that the engine it was on produced around 250hp with lots of tq
However being a slow military vehicle , reliability was was key.
I would hope it could squeeze enough air for 300/350bhp.
When I can I will post an image. If anyone knows much about gmc chargers is love to know more.
(10-13-2013, 09:53 AM)MFSuper90 EDH ran with only a supercharger for awhile, then added a turbo later
Here is the build thread
http://www.superturbodiesel.com/std/Thre...hlight=EDH
Eaton m90, which is micro sized compared to the 6v53/71/92 blower you are planning on using.
Besides just having one around, I think using a screw type would be much more beneficial, just from what I've read
Oohh, this will be a sucsess!! Stick it on and run a intercooler on it and it will be sweet! I put a turbo on because i was aiming for the 4-500 hp range
The car felt just like a strong N/a engine with just the supercharger

So if it came from a v6, it narrows it down to a 6v53,6-71, 6v71, 6v92. All are from the old two stroke detroits
I honestly don't know how to tell the difference between them. Serial numbers would be the easiest, but measurements might help also

How do I tell between them? I'd imagine the numbers determine the size. I will check for serial numbers...

6V51 is a 6 cylinder in a vee config that displaces 53 cubic inches per cylinder
The last two numbers tell you the cubic inch per cylinder of the engine. Either way that supercharger will be more then enough volume for a 606. Im not so sure about what sort of pressure they could develop effectively. I would do some research or testing to see how far you can overdrive this thing to make pressure. Two stroke diesel's super charger's were only used to push air through the cylinder liners for for exhaust scavenging, not boost per se. Detroit later turbochargers their engines for more power (6v51T), these force air into the inlet of the supercharger.

Just for clarification; the 51 series Detroits weren't made in a vee configuration.
I believe you meant to say 6v53 & 6v53T.
Wiki says that only inline 2 & inline 4 were made in the 51 series but there were also single cylinder 51's made as well. Way to go wiki!

Have spent the morning looking at these online. You can tell the differace between the v and non v fairly easily as the mounting or base plate is different I don't think it's the 53 as that looks a bit small compared.
When I'm in the workshop I will look at serial numbers as I'm just speculating right now!
Although mine has a mechanical govener on it which I don't see on many online? Not sure if that helps to determine? Or do most just get taken off??
I think the mechanical governor your seeing is either the blower bypass valve or the emergency air shutoff
(10-15-2013, 08:56 AM)hansendk It looks more like a 8V71 blower and its the governor for engine speed that's on it.
there is no bypass valve a 2 stroke diesel will not run without the blower turning.
we have on in the shop so I can compare tomorrow at work

(10-15-2013, 07:43 PM)hansendk i just messured the rotors on the dismantled blower from the 8V71 we have here at work and they are 16 inch long
your blower can be from a 6V engine Detroit might use the same blower on both 6V and 8V

I see these problems
1. 2 times oil pressure 1 in each end of the blower, 4 times oil return 2 in each end.
2. there is no pulley you have to fabricate bearing and pulley holder
3. its moves to much air means you might have 15 psi at 1000 rpm which is to much at that rpm, but can be regulated with pulley size or maybe a waste gate
remember max rpm on the Detroit is around 2500, the best was to know how much air it moves pr. rpm and the max rpm its designed for.
4. its heavy needs a very solid base to mount it on last thing is space if you don't do as Mantahead
everything is possible but you need good fabricating skills and be prepared for some problems but who knows it might be a super engine in the end or a blown engine, but anyway that why we play with engines
I am lucky its both my hobby and my work.

The problem i see here is just wheelspin when you floor it at idle
Ok, I have been at the workshop today.
Blower has cleaned up really well, rotors are in ok shape. More than good enough to make good boost.
The ID plate on the blower says its a 6-81 , I can't find anything online about that? As if it don't exist? Anyone shed light on this?

Then its probably going to come down to detailed measurements and more info from the previous owner. Some good old sleuthing!
