Engine/Transmission (1998.5 - 2002) Why not supercharge??

[RAndrae]

Just wondering why no one has tried to supercharge a CTD?

I believe it has been tried, but with the great turbos available it may not be worth the expense & effort.

I always wondered especially with all the new type chargers out there. They are smaller and more efficient than a GMC roots type. I would think it would be instant boost no lag etc.

Beat me to it... thats the only one Ive heard of

I guess the trick is to do something like them old Detroits do, have a bypass open open based on boost. and rum a big huge single for the "bottom" charger.



Your not really going to be able to re-compress well with a roots or anything like that from what I understand.



Think of the blower as nitrous to get the big turbo going

Was talking to my salesman @ Procharger and he said that there are some powerstroke guys out west that are using some of the big head units with 1 turbo. He said the problem is, since the diesels don't turn the high rpm's like gassers, they don't make the boost. But they are working on different step up ratios & pulley size.

Keep in mind that the old Detroit's were 2-strokes and required a blower to run. I absolutely hate the engine, Detroit in general, but still... Nothin quite sounds like an 8V92 at full boost!

Or two 671's in an old USCG 40 footer! SNOKING

In the 1960s I worked for a sand & gravel company that had two GMC dump trucks, one with a 4-71(the screamer) and the other a 6-71, Detroits.

I would hear the guys driving them in and out of the yard and they sounded so neat, especially with a load. I was sure they were turning 5 or 6000 RPMs,and had Hotrod type horsepower.

When I finally started driving them, I was a little disapointed, especially in the HP and RPM dept. They did'nt have much of either.

I still love their sound. Although they're not around much anymore, I will always stop, watch, and listen when I hear one coming.

I'm not sure, but I think driving those trucks was probably the starting point of why I'm half deaf now. Oh yes, I still like noisey engines though. Genetics, I think.

Those two-strokes had plenty of RPM... When they run away on you and grenade into millions of pieces! Kinda hard to beat the sound of one of those!
