Whipple Supercharged Duramax Diesel with Water Injection - Vid

[71catruck]

The old 2 strock detroit diesel engines dont have intake valves, the bottom part of the cylinder wall has slites Cut into it. Think of it like a water jacket that surrounds the cylinder but its full of air and when the piston moves down to expose the slites then the air gets in. Since there is no intake valve it doesnt have and vacume to lpull air into the motor on start up. The blowed was gear driven and provided that air. The turbo was used to make the power.

Thought so, and they were 4 valve heads too. Hence the distinct sound they made.

Yep, those old 6-71 and 8-71's made some noise. That power band was stupid though. Ask me how I know.

How is that blower spinning with no belt?
Probably the backside of the blower now that I look at it more.

Yep. You're looking at the back of the blower.

Interesting video. The water injection setup is really neat. I searched YouTube for (hopefully) a video of this bad boy at a track but couldn't find one.

There are a few vids out there when it still had turbo's on it Bob.

Search for
Banks top diesel dragster

That should give a little insight to it. lol

I wonder why they would move from turbo's, doesn't seem like any advantage there?

Also the 7.1 DMAX never really caught on either, people were making so much power with the base 6.6 there was really no need for the big $$ for 7.1 parts.

I wonder too why they would go from turbos to a supercharger.

This isn't a pickup truck.
When they were running turbo's IIRC the were spraying it to help low end and getting it to spool.

So believe it or not for this application the S/C may be better.
