Yank SS-4000 + Dyno #s??

How much HP should I expect to be taken up by my Yank SS-4000 converter unlocked on the dyno? Just trying to put some #s together.

Just found another thread that gave me some insight. About 34-hp with the Yank SS-4000

But if you can add anymore please fell free.

WOW that is BIG #s for locked and unlocked.
I have to get mine Dynoed with it locked up to get some good #s then. I have H/C and stock gears and just put down 378 unlocked.

Doesn't mean your car will be the same.This was a race car with alot of extension in the converter.The car runs 10.8's at 124mph -3650lbs.I've seen some people only gain 10hp on the dyno with it locked.

My car dyno' d 360/371 locked and 319/312 unlocked. SS3800 3.23s. I had it tuned a couple times, and both runs were about the same loss.

I' m not worried about it. My brother was running 107 MPH in the 1320 before the stall, with 2.73s, and after 3.73s and a SS4000, it ran a little more than 108. Seems to be a pretty efficient converter. The unlocked numbers looked kinda' scary, but, Yank confirmed it' s normal for the SSs and it looks to be true.
