Detroit Diesel Super Charger rebuild kit sourcing?

[Garymci5]

If anyone has input on a good source to get them, would be grateful for a link or any company info.!

Think my SC is sucking oil

It is called a

roots blower

not supercharger. ( they are fundamentally different applications. )

Identical actual thing, different application maybe, I remain convinced it's a roots blower that is acting as a supercharger.  The air pressure in the air box is higher than atmospheric by about 2psi, therefore you have a 2 psi supercharger.  But that's semantics and no one agrees with me.  Anyone asks me, I say "durn right it's supercharged, It's a bad-@$# 8V71!  Watch my smoke!"

when I asked this question, the best advice was that you may be able to buy the kit, or the seals, but the $1000 worth of  special tools and the training to actually rebuild the thing makes the rebuilt blowers available from the rebuilders for about $500 - $600 a bargain.

Had a Marshall-Nordic Roots type Supercharger on my 1948 MG-TC.  Would out-drag an Austin Healy back in those days (1956-58)!  A fun car until a rock got in through the unfiltered carburetor and got into the blower and ruined the magnesium rotors!  Still have the blower.

Ah, the "old days" when kids had fun with their cars and not putting in earth-shaking stereo systems like today!!

You will have better luck getting the parts from www.dieselpro.com in Fl the kits are 159.00 for the small bearing blower and a little more for large bearing model if seals are all you need they are less than 3 bucks each 


good luck

Many thanks, and even more for the add'l tech tip! Now the journey begins, after all the OTHER ones I need to finish first....

Gary, Diesel Pro is the best place for you guys to order parts they do cost a little more but it is a easy site to order from and plus they have pictures lol and they sell to the public where McBee and FP won't 

good luck

Me thinks someone ought to study up before (self) proclaiming Professor status. Maybe the world is flat?..?

Semantics aside, it is generally called a "blower" among Detroit Diesel folks.  You will sound more knowledgeable if you use that term.

If you call it a "supercharger", the parts guy is likely to ask if you mean "turbo charger".

Yeah, Well OK, That pretty much puts and end to my participation here.
Apparently I don't know CARP about anything, The X-Purts have made
that clear.

Dave, don't be a jerk!  It's just people, it's just words, we love ya'.

[Garymci5]

With all due respect: since when is (trying) to ONLY correct semantics-- tech terms-- when someone posts a clear question, actually called "participation"? 

If I am violating the International Standards of Technical Terms, herafter referred to as ISTT, please by all means continue to treat me as the dolt, that I appear to be 

Did you (anyone really), know that a turbo is a form of super charging? In typical auto coloquialism, a supercharger has been known to be a Blower (Roots is a type, the DD's are a 2 lobe), but as someone else pointed out could also refer to part of the turbo system (for a DD 2stroke anyway); it's a dual stage supercharged system-- cars are now using the same SC and Turbo technology together and calling it "Twin Charged"; see VW.  Supercharging is a flexible term it seems.

I'm all for people saying stuff, but if someone is going to "venture" a statement (like that), then be open to the idea someone might have something to say in return- - after all it IS a forum and that IS why we're here (right?) 

So, there's really no need to run off in a huff, but maybe a little more Participation could both be helpful and positive (which is always good).

DD calls it a blower you take a 671 blower Teflon it put on a big block Chevy it becomes a supercharger and on the Cummins Diesel it a supercharger what the hell is the big deal here it's just a different name for the same thing.


good luck

It is a little more than just semantics.  As Dave said, it is a different function.  A supercharger is used to force more air into an engine, thus increase the horsepower.

The blower is only used in a two stroke engine to scavenge the exhaust gases because there is no exhaust stroke.  The two cycle engine will not run without it.

The 6-71 blower does indeed become a supercharger when you install it on a four stroke engine.

This has been beat to death in earlier threads with the same hurt feelings.

So, call it what you want.  When you go the the dealer and ask for parts for your 8V-71 supercharger, he is going to smile real nice at you and double the price.
