Schwitzer Ball Bearing turbos

[JohnSpina]

Anyone have any first-hand knowledge of Schwitzer turbos? I am installing a pair of these ball bearing turbos into my project car. They are used on a John Deere diesel but I'm not sure what they are capable of. They have small housings and appear to be able to do the trick for a street driven car. I can't seem to find out what the map spec's are for them. Here is how the fab is going:

They both feed into a custom front mount IC with a single 3 inch discharge. The plumbing is pretty straight forward, individual wastegates on each side, tee'd together using a bypass air pressure regulator for boost control.
I'm days away from running the car, but it'd be nice to know if there are any flow spec's out there that can justify the use.

Any ideas?

John,


They are very good durable turbos.If you have any numbers on the tag I can get the flow numbers.Good luck.Scott

If you have the compressor wheel dimensions, I can compare them to the 3000GT/Stealth twin stuff and get an idea of HP capability.

Here's a challenge. I don't have any spec on this turbo, but I'm using two of them. They're small, and will probably spool like a banshee. I would like to find out how much airflow at what boost the turbo is best suited for, and whatever info anyone might have.

The turbo in question is a Schwitzer designed for John Deere applications:

Schwitzer Mod. S1B
John Deere P/N RE 71550
Schwitzer P/N 316101
Serial No. 03E01-0296

Any help very appreciated.
