Can a diesel supercharger be used on a gas engine?

To everyone that wants to overhaul their own blower: unless you are a machinist and are used to working with 1 thousandth, do yourself a favor and take it to a blower specialist. You need special equipment. You need to know all the specs. You need to be able to work at very close tolerances. A blower that isn't assembled correctly will self destruct in a little bit. It's not that you can't learn, just get someone to show you how before you ruin what you have. Your intake has to be perfectly flat. The original 6-71 cases have a lip that has to be machined off before you can use the case. If you take one that needs new parts and run it without, you may get the priviledge of watching it self destruct with rpm before your very eyes. Someone needs to show you the correct proceedure for starting a blown engine. There's lots to learn and it's very unforgiving.

 

Do you have any links or pictures you can post? I'm working on installing a 225 slant 6 in my '34 Dodge pickup right now and I'm interested to see various power adder combos. Yours is the first roots blower slant I've come across.
Thanks!

I will try and remember to send some pics to you in an e-mail sometime this weekend. I am at work right now and do not have any way to do that from here.

 

So, if someone did decide to upgrade a 6V71 do the bearings and plates from a 671 fit onto it? Or do you have to get performance parts specifically for the V series?


Also, there was a webpage with a guy who had a 471/slant6 in a duster or something. It looked pretty damn sweet with the blower offset, sideways and sticking through the hood...now I can't find the page.

 

is there any way i would be able to talk you into sending me those cnc program files ? i could certainly use them

...another zombie from the grave appears.....

 

There is a way.... it involves sacrificing a chicken, a dark room and a special "channeler".
Or you could try sending a PM, who knows if the OP is lurking occasionally.

 

Use someone`s smart phone to take the pics. Log into the HAMB on their phone and pots the pics that way. Just post them as `full image`.

 

OP question was 2006 Pete. Some time ago.

 

Cheers I really need to look at post dates.

 

You can tell it's old-the CNC program is saved on a disc. Probably a 3.5" floppy

 

Hello,

With the question in mind, something as technical as modifying a stock diesel 671 supercharger is no laughing matter. When my brother and I wanted to get a 671 for our newly acquired Isky Gilmer Belt Drive Kit for the SBC motor, we looked everywhere. People had access to a ton of diesel junkyards and suppliers of diesel parts in the Long Beach/Los Angeles Harbor area. Diesel motors were on the huge trucks coming in and out of the harbor docks on a daily basis. They still do today.

But, we decided that such a integral part of our new build should get some expert help and work to make the best of a good solution. So, we scoured the diesel dealers along the PCH corridor in Wilmington, CA for a purchase of a used one that fit our budget. As we searched several shops, one stood out in a nice showroom display. Red painted diesel motor was on a stand and on it was a sandblasted 671 supercharger. It was not painted to show those shoppers what it looked like not painted, as almost 90 percent of the diesel superchargers were shown/ordered painted in matching colors.

The sales guy said for a low cost, he could sell us the demo 671 in sand blasted form, but it was not sold as a new supercharger. Since it was a display, now, it was technically “used.” So, we got a “used” and very low cost version from a diesel dealer’s showroom. He was going to get a chromed or polished version to make his diesel motor display stand out even more. But, had to sell the old, “new” one to get a polished chrome one for his display.

With something so critical as adding extra boost to a high performance motor was important to us. But, we did not want to start with something already used by someone else or not for racing specifications. So the experts at Reath Automotive did their magic and now we had a ready to go “New” 671 supercharger for our 292 c.i. blower spec motor.
Similar motor set up from 1960.

Go to a certified supercharger dealer/builder, like Don Hampton superchargers run by one of the 1950s-60s old drag racers from So Cal, still in business of superchargers.
NOTE 2:

Don Hampton is very well known in the drag racing circles. He teamed up with Kenny Lindley in the white full body FED in 59-60 and that became a great competitor everywhere. As stated before, we saw this FED almost every week at Lions Dragstrip. It was a hard charging race car with a very skillful race car driver.
Here’s coming at you…

Don Hampton has gone on to being one of the top custom blower drive kit producers in the industry. There is plenty of background in drag racing and in all applications of his shop’s supplies, staff and crew.

The above Clay Smith Engineering ad was in 1959 during the cam builders' “ad war” in the Drag News paper every week. The Clay Smith Speed Shop was just down the street from our house in the Westside of Long Beach. In this ad, they were located near the 405 Freeway, LB Airport, Signal Hill. That portion of Long Beach, later on, was near Reath Automotive's newer corner building, just up the street, on Cherry Ave and 33rd.

I built a 3-71 blower to be used on a Flathead Ford v8–built my own intake from a single four barrel intake—had the rotors pinned to keep from slipping on the shaft(they are only pressed on as diesels turn low rpm)/ found a local gmc mechanic with 50 years blower experience—set up blower at .010 clearance everywhere one could place a feeler gauge. Yes, he said he could have set up tighter(less clearance) but the tighter clearances wouldn’t have radically changed how the blower performed( this is a street car) All of the 71 series blowers(gmc) use the same end pieces front and rear and the only differences are longer rotors and longer cases. Flatheads Forever!!
