Supercharger vs turbocharger

Im not very experienced with the ole 2 strokes, but i believe the 6-71 was am inline motor? In detroit fashion the 12-71 was two 6-71's glued together (more or less...).
6V53 and 6V92's were v blocks.
If i am wrong on the 6-71, someone, please correct me....

 

was the 12V92 ever factory installed in trucks?
I had the "pleasure" of driving a 12-71 truck for a brief time some years back. Low geared, all in at 60 mph, engine brake and a 13 speed. Sure could make alot of noise with that truck...

 

I used to drive an old cracker box Jimmy with a 238 Detroit and a ten speed. The engine was an inline six. 6-71. The engine had a bad habit of running backwards on shut down filling the cab with white smoke. The only way to shut it off was to put your foot on the brake let the clutch out.
The same company had another truck powered by the 12v71. We used to call it the buzzin dozen because that's exactly what it sounded like.

 

im interested in a blower if u still have one for sale...new prefered but used will do...thx in advance please get back to me

 

The 6-71 is an inline engine. The 6v-71 is a V block engine. The 12v-71 is two 6v-71 blocks bolted together to make the 12v.

 

Backpressure does not take any HP to remove.

In a naturally aspirated engine, exhaust removal is accomplished by the pressure and air intake is accomplished by the vacuum created by the pistons. A small amount of backpressure greatly affects the amount of air that can be drawn in. Less air/fuel in means less HP created.

In a turbocharged engine, the intake side has pressure. When the intake valve opens, air is forced in. It doesn't have to wait for the piston to create a vacuum, so the exhaust backpressure created by the turbo has virtually no effect on the incoming air. That is why it doesn't rob engine HP.

Backpressure created after the turbo is a problem because it keeps the turbo from working properly.

As far as putting a turbo on your car, it would work with a properly sized turbo. A small car engine couldn't even begin to spin one of those big turbos fast enough, let alone two.

 

Bender I have been around DD all my life and have never seen a 1271 made out of two V671, the 1271 is a single block, now the 1292 is two 692 bolted together, same goes for 1671's= two 871 bolted together 1692's = two 892's and it goes on an on 2471= 2x1271.

 

Then I've seen some freaks, they were in trucks.

 

Ran a 1271 and it was one solid block. Ran a V16 also it was 2 318' s bolted togather. Lots of noise, used lots of fuel and still didn't make much power

 

lol superchargers are like a blowdryer compared to a fan on a block of dry ice.
