OBS vs. EARLY 99 vs. LATE 99 Turbos. Info needed.

Does anyone know what the *STOCK* CFM rating is on these 3 setups? I'm mainly curious about the early vs. late setups, but I thought I'd add obs for giggles.

I've been poking around and can't seem to get a GOOD answer.

I have been told by a good diesel shop that the stock late 99 is around 850 and the OBS/early99 is around 800.

That is when I was researching turbos. Give BWD a call, I talked to Kevin. Give Bean a shout as well. And while you are at it call ITP, DI and WOP. Then take the average to get a close answer.....LOL....

It appears I'm always on your trail. That is almost exactly what I did. That's how I came up with the 800-900.
