turbo: blow thru vs. draw thru
Thats the one! It is on a engine stand now.
When you get a chance, write down the numbers on the turbo tag. Should be riveted down on the side of the compressor discharge nipple.
It should have a couple of lines, the top line will have both numbers an letters like :
3 A1 EE _ _ _ B1
There may be dashes for blank spaces, or info in those underscored lines above.
The second line will be a number, usually six digits with a dash & two more digits like this:
600586-62
That will tell me a little more about the compressor.
I would be a liar if I said that 500 hp number was easy for that turbocharger. It took a special trim on the compressor wheel, and was basically all that unit had. It was out in the 55% part of the island near the choke line to get the job done. Back then we just did not have the turbocharger selection that is available today.
A lot of Gale's motorhome units were 4psi setups. The ran in Vail, CO like a stocker did at the beach. A huge improvement to be sure.
